Full textAbstract:
Rosa ×scabriuscula SM. has been proven in southwest Lower Saxony. The hybrid between R. tomentosa (subsect. Vestitae) and R. canina (subsect. Caninae) is fertile and spreads much more strongly at the place of growth than the parent species. R. ×scabriuscula can be easily distinguished from the parents. It is very similar to R. tomentosa as seed parental species. R. canina determines the position and persistence of the sepals. It also significantly influences many other characteristics such as hairiness and glandularity. This is remarkable because hybrids between the subsections Rubigineae and Caninae are known to be largely similar to the mother plant and the paternal genome mainly only determines the sepal position and the diameter of the orifice. In the occasional glandular population on the branches, the hybrid shows a feature that was not observed in the parents. Characteristics of the stipules and sepals can be helpful in distinguishing R. tomentosa from similar species and hybrids.

Full textAbstract:
The aim of the present study was the investigation of the antioxidant activity of plant extracts from Rosa canina, Rosa sempervivens and Pyrocantha coccinea. The results showed that the bioactive compounds found at higher concentrations were in the R. canina extract: hyperoside, astragalin, rutin, (+)-catechin and (-)-epicatechin; in the R. sempervirens extract: quinic acid, (+)-catechin, (−)-epicatechin, astragalin and hyperoside; and in the P. coccinea extract: hyperoside, rutin, (−)-epicatechin, (+)-catechin, astragalin, vanillin, syringic acid and chlorogenic acid. The total polyphenolic content was 290.00, 267.67 and 226.93 mg Gallic Acid Equivalent (GAE)/g dw, and the total flavonoid content 118.56, 65.78 and 99.16 mg Catechin Equivalent (CE)/g dw for R. caninna, R. sempervirens and P. coccinea extracts, respectively. The extracts exhibited radical scavenging activity in DPPH and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS)•+ assays and protection from ROO•-induced DNA damage in the following potency order: R. canina > R. sempervirens > P. coccinea. Finally, treatment with R. canina and P. coccinea extract significantly increased the levels of the antioxidant molecule glutathione, while R. canina extract significantly decreased Reactive Oxygen Species (ROS) in endothelial cells. The results herein indicated that the R. canina extract in particular may be used for developing food supplements or biofunctional foods for the prevention of oxidative stress-induced pathological conditions of endothelium.

The presented research aimed to study the numerical taxonomy of the genus Rosa L. and to identify and differentiate its various species grown in different regions in Kurdistan, Iraq. This study proceeded in the 2021–2022 season at the College of Education of Pure Science, University of Mosul, Mosul, Iraq. Forty morphological quantitative and qualitative characteristics, including vegetative and reproductive traits (leaves, flowers, fruits, seeds, and pollen grains), gained taxonomic analysis. From there, selection of 12 morphological features finally drew polygonal shapes for the concerned species. The analysis of the polygonal shapes revealed the species owned significant variations in these forms. The similarity among these species ranged between 0.5% to 91.0%, and the highest level of similarity (91.0%) occurred between the two species Rosa canina var. ‘canina,’ and Rosa canina var. ‘verticillacantha,’ and the lowest (0.05%) emerged from the species. R. elyamaitica and R. dumalis subsp. boissieri. From the cluster analysis, the UPGMA dendrogram separated the 13 species into three main groups and subgroups. The first main groups, divided into two subgroups, included the species R. canina var. ‘canina,’ R. canina var. ‘verticillacantha,’ R. canina var. ‘dumetorum,’ R. canina var. ‘deseglisei,’ and R. dumas subsp. boissieri. The second main groups included the species R. eiyamaitica and R. heckeliana subsp. orientalis. The second subgroup included the species R. gallica, R. centifolia, and R. damascena. Moreover, the third main group included the species R. foetida, R. foetida var. bicolor, and R. hemisphareaca.

Full textAbstract:
The rosehip (Rosa canina L.) fruit has gained researchers′ attention due to its rich chemical composition in vitamin C, phenols, carotenoids, and high antioxidant activity; meanwhile, polymers such as pea protein are generally recognized as exhibiting a protection role against the extrusion process. Corn snacks extrudates obtained by replacing corn flour with 10% R. canina powder (R) and 10% R. canina with pea protein (RPP) were evaluated for the physicochemical, textural, optical, and nutritional characteristics. A sample manufactured without R. canina powder was used as a control. Hardness, crispiness, chewiness, and solubility index (WSI) of the final extrudates were improved by addition of R. canina and pea protein powder (PP); meanwhile, b* (yellow/blue coordinate), C (chroma), and h* (tone) optical parameters were significantly different from the control sample (p < 0.05). Extrusion highlighted a negative impact on total phenols, carotenoids, vitamin C, and antioxidant activity extrudates, while PP exhibited a good protection against the extrusion process. In vitro digestion increased the bioaccessibility of vitamin C, folate, antioxidant activity, total phenols, and total carotenoids mainly on RPP extrudates.

Rosa canina fruits have been used traditionally for the treatment of diabetes mellitus and its complications. The aim of current study was to evaluate the in vitro mechanism of action of R canina in managing diabetes mellitus. Cell proliferation and cytotoxicity assay were performed on pancreatic β-cells, βTC6. The protective activity of the extract on streptozotocin-induced death in βTC6 cells was studied. The effect of R canina on the metabolism of glucose in HepG2, a hepatocellular carcinoma cell line, was evaluated. The effect of the extract on glucose diffusion across the dialysis membrane, which is a comfortable model for assessing cellular glucose absorption, was evaluated. The results obtained from current study confirmed that R canina extract can act as a growth factor for pancreatic β-cell line providing a novel mechanism for the observed antidiabetic effect of this natural agent. Further preclinical studies are necessary to evaluate the perfect mechanism of action of R canina in diabetes mellitus.

Full textAbstract:
The Egyptian narrowly endemic and critically endangered plant species Rosa arabica Crép. was studied employing a taxonomic and molecular approach. Morphological investigations, distance analysis, and phylogenetic reconstruction revealed that R. arabica is a distinct species with great affinity to R. canina and differentiated from R. rubiginosa. Molecular identification based on the sequences of multiple markers single or in combination ITS, matK, rbcL, and trnL-F succeeded in identifying R. arabica at genus and species levels. We evaluated the potential of each marker and a combination of the nuclear ITS -Internal Transcribed Spacer- with one of the plastid markers, matK, rbcL, or trnL-F, to accurately identify Rosa species. All of them were successful in identifying R. arabica. Classification based on DNA sequences shows that R. arabica is placed within section Caninae in a clade comprising R. canina and R. rubiginosa. Moreover, R. arabica is closely related to other European Rosa species. In conclusion, our results indicate that the four DNA markers can provide species resolution in the context of the genus Rosa and relatives, aiming to characterize morphology and genetic diversity in the ecological and economically important genus Rosa.

Angiogenesis, known as blood vessel growth from preexisting vasculature, occurs when proangiogenic overcomes the angiogenic factor. The most important angiogenic factors (promotors) of angiogenesis were vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), fibroblast growth factor (FGF), platelet derived growth factor (PDGF), angiogenin and tumor necrosis factor (TNFα). Rosa canina, commonly known as rose hip or dog rose, widely distributed in Europe, Asia and North America, belongs to the Rosacea family. Different biological compounds were found in R. canina, such as high phenolic composition (specifically flavonoids), vitamins as vitamin C, carotenoids, and fatty acids as (linolenic acid). Polyphenolic compounds are very important due to its efficacy as antioxidants and antiangiogenic. The dried powder of R. canina was extracted by using successive solvent extraction according to polarity (hexane, ethyl acetate and ethanol). The yield% of hexane, ethyl acetate and ethanol extracts were (0.8, 1.2 and 2.4 g per 100 g dried powder). Rat aorta assay (ex-vivo) was done to investigate antiangiogenic activity and choose the most bioactive extract. IC50 of avastin (positive control), ethanol, ethyl acetate and hexane were 20.281, 33.582, 61.744 and 94.537, respectively. The results revealed that ethanol extract (EE) was the most biologically active extract. Chorioallantoic membrane assay (CAM) in-vivo was done using R. canina ethanol extract. eosinophilic esophagitis (EE) has a greater percentage of inhibition of blood vessels when used in two concentrations 250 and 500 mg/20 mL. The zone of inhibition as mean ± SD was 19.921 ± 4.048 mm and 30.302 ± 2.805 mm, respectively. Thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC), was used to identify the phytochemical constituents of the EE. In the present study, EE of R. canina revealed six flavonoid compounds (rutin, quercetin, catechine, astragalin, hyperoside and gallic acid) that could be responsible for the biological activity of the ethanol extract. In conclusion, the EE of R. canina reported a promising antiangiogenic activity both ex-vivo and in-vivo that may be attributed to the flavonoid content of the extract. The purpose from the study in order to investigate the antiangiogenic activity of R. canina extracts ex-vivo and in-vivo.

The genus rose hips, or rose (Rosa L.), belongs to the Rosaceae family. It has many cultural forms, bred under the general name Rose. Now, more than 400 species of rose hips known. Usually these are erect shrubs, less often lianas, sometimes-low tree-like forms or almost herbaceous plants. Rosehip is common in the temperate and subtropical zones of the Northern Hemisphere, it can often found in the mountainous regions of the tropical belt. Some types of rose hips distributed from the Arctic Circle in the north to Ethiopia in the south. On the American continent - from Canada to Mexico. The most favorable conditions for Rosehip are in the Mediterranean region. Several species of the genus Rosehip have a wide distribution area. Kazakhstan possesses significant resources of medicinal plant raw materials. Among the most priority representatives of the wild flora are species of the wild rose genus - Rosa L. as the most valuable medicinal plant. In total, 21 species of wild rose grow in the republic, including 5 in Central Kazakhstan: R. glabrifolia - w. naked, R. laxa Retz. - w. loose, R. acicularis Lindl. - (w. Spiny), R. majalis Herrm. (R. cinnamomea L.) - w. May (w. cinnamon) and R. pimpinellifolia L. (R. spinosissima L.) - w. femoral. Kazakh species of the genus Rosa L Rosehip fruits distinguished by a high content of biologically active substances and are widely used in medicine. Plant raw materials collected in the southern region of the Republic of Kazakhstan (Almaty region). The crushed air-dry raw material was extracted with hexane and chloroform in a raw material-reagent ratio (1:10) in a Soxhlet apparatus. Plants of the genus Rosa are rich in vitamins A, C, E and group B, and also contain sugars, flavonoids, saponins, phytosterols, glycosides, tannins, organic acids, amygdalin, essential oils. Thus, rosehip is a promising raw material for the creation of domestic medicines. This article examines the study of the quantitative composition of amino acids and vitamins in the fruits of the species of the genus Rosa widespread in Kazakhstan in the supercritical extract, isolated and the fruits of the Rosa canina plant, in order to establish the possibility of using and with the subsequent cultivation of the selected species.

Abstract Rosa canina L. fruit have been used internally as tea for treatment of viral infections and disorders of the kidneys and urinary tract. Also, it was reported that the R. canina fruit, with its high ascorbic acid, phenolics and flavonoids contents, have antioxidant, antimutagenic and anticarcinogenic effects. Antioxidants neutralize free radicals, which cause oxidative damage to lipids, proteins, and nucleic acids and thus protect the organism. Research studies conducted on this topic have shown that natural antioxidants are involved in protection against many diseases: cancer, cardiovascular diseases and osteoporosis. Different processing and storage methods of the fruit could affect the bioactive nutrients while preserving the antioxidant capacity of them is very important. The aim of this study was to evaluate the effect of storage in a dry or frozen state on the antioxidants content of R. canina fruit. The evaluation involved determination of carotenes, ascorbic acid and total polyphenols using spectrophotometrically methods. Analysis performed on the R. canina fruit showed significant changes in the antioxidants content in fresh, dried and frozen fruit during storage.

Full textAbstract:
Rosa canina L. is among the woody species which thrive through diverse habitats and is distinguished for its high nutritional value. In recent years R. canina L. has raised awareness due to its high demand in cosmetology and pharmacology. This study focuses on the results of a three-year experimental site including four R. canina L. genotypes treated with two fertilization regimes (conventional, organic) and harvested under four ripening stages. Τhe results indicate the most suitable period for harvesting the rosehip fruit in terms of ascorbic acid, antioxidant capacity and total phenolic compounds. This study recommends the first two ripening stages in order to achieve the highest concentration of ascorbic acid (4.53 mg g-1 F.W.). The last ripening stage came across as being the most appropriate stage for the highest total phenolic content (31.2 mg GAE g-1 FW) and in the meantime, this study highlights that the distinct ripening stages do not fluctuate the levels of total antioxidant capacity. Overall, the current study tries to identify the nutritional potential of domesticated R. canina L. and specify which of the ripening stages and fertilization regimes maximize its post-harvest value.

In Lower Saxony, R. ×scabriuscula and hybridogenic R. micrantha successfully spread locally. Their number significantly exceeded the number of R. canina, which is usually predominant in rose populations. They were more successful in colonizing dense herbaceous vegetation and as pioneers of young succession areas than other rose species. Four independently evolved hybrids of the Aosta Valley, morphologically assignable to R. rhaetica and transitional forms between R. caesia and R. rhaetica, also proved to be predominantly successful spreaders. R. rhaetica is recorded for the first time for Aosta Valley. The four hybrids are compared with R. rhaetica from the Lower Engadine. R. rhaetica and R. micrantha represent morphospecies like probably most species of Rosa sect. Caninae. Glandular characteristics of sepals and pedicels of hips may indicate hybrids between the subsections Vestitae and Caninae. Whether these characteristics, as well as the length of pedicels, are well suited for the determination of hybridogenic R. micrantha remains to be verified. The hybrids were identified by morphological characteristics. The ploidy level of one population was known supporting the identification.

Розглянуто вміст, компонентний склад та кількісне співвідношення алканів, що входять до складу воску пелюсток рослин представників роду Rosa L., що культивуються у Північному Лісостепу України. Актуальність і перспективність дослідження обраної проблеми зумовлена тим, що вихідні дані видів, що застосовуються в інтродукційній, селекційно-генетичній роботі, впливають на прогнозовану адаптацію та стійкість рослин. Дані про фітохімічний склад рослин необхідні для розуміння функції, яку відіграють сполуки у рослинах і мають важливе науково-практичне значення. Стійкість рослин, зокрема генеративних органів, визначається багатьма властивостями кутикули, що містить вторинні метаболіти. Важливі функції поверхневих восків доповнюються здатністю рослин утримувати та накопичувати тверді частинки забруднювальних повітря речовин у міських фітоценозах, яка варіює залежно від виду рослин, але у всіх видів позитивно корелює з масою кутикулярного воску. Нерозгалужені довголанцюгові алкани забезпечують гідрофобні властивості листкових восків і виступають первинним бар'єром рослин від зовнішніх умов середовища, захищаючи листки від втрат вологи шляхом транспірації. Види роду Rosa L. є багатим генетичним потенціалом дослідження, оскільки видовий склад роду становить 180-400 видів, згідно з різними джерелами. Стійкість природних видів зумовлена еволюційним відбором. Вивчення п'яти видів роду Rosa L.: R. multiflora Thunb., R. spinosissima L., R. canina L., R. centifolia L., R. rugosa Thunb здійснювали на базі колекційного фонду Національного ботанічного саду ім. М. М. Гришка НАН України. Ці види належать до трьох підродів і п'яти секцій: Підрід Stylorhodon Dumortier, Секція Synstylae DC. – R. multiflora Thunb.; Підрід Cynorhodon Dumortier, Секція Caninae Crep., Підсекція Eucaninae Crep. – R. canina L.; Секція Rugosa Chrshan. – R. rugosa Thunb.; Секція Gallicanae DC. – R. centifolia L.; Підрід Chamaerhodon Dumortier., Секція Pimpinellifoliae DC. – R. spinosissima L. Органічні леткі речовини виділяли традиційним методом – паровою дистиляцією. Леткі компоненти визначали з використанням системи ГХ-МСД Agilent Technologies 6890/5973. Для ідентифікації компонентів використано мас-спектральні бібліотеки NIST 05 та WILEY 2007 із загальною кількістю спектрів понад 470000 у поєднанні з програмами ідентифікації AMDIS та NIST. Усього визначено 28 компонентів, які належали до середніх або рідких (С10-С15) та вищих або твердих (С16-С34) алканів. Найбільший вміст алканів відзначено у пелюстках видів R. multiflora (72,06 %) та R. canina (87,50 %), середня кількість – R. centifolia (57,18 %), невисоким вмістом відзначилися пелюстки видів R. rugosa (14,58 %) та R. spinosissima (16,84 %). Для всіх досліджених видів шипшини характерна наявність насичених нерозгалужених вуглеводнів, таких як декан, тетрадекан, пентадекан, гексадекан, гептадекан, октадекан, нанодекан, генейкозан, трикозан, тетракозан, пентакозан, гептокозан, нанокозан, гентріаконтан, що показує їхню виняткову роль у складі восків пелюсток квіток рослин.

Full textAbstract:
The aim is to conduct a comparative pharmacognostical study of the series of roots of Rosa (R.) majalis Herrm. and Rosa (R.) canina L. with the establishment of diagnostic features of morphological and anatomical structure and boundary limits of numerical indicators of raw materials.
 Materials and methods. The fresh and dry raw materials were used to study the macroscopic microscopic features by microscope Delta optical BioLight 300 (Poland). Determination of total polyphenols was performed by spectrophotometry (on a spectrophotometer Optizen POP (Korea)) and HPLC (chromatograph an Agilent 1200 3 D LC System Technologies (USA)).
 Results. The morphological (nature of the surface (periderm) and fracture) and anatomical (color of cell walls and their cavities; location of the sclerenchyma; the presence of a crystalline coating of the sclerenchyma at the root of R. canina; of various elements of the remains of the tetraarchic conducting bundle in the center of the root) diagnostical features of roots of R. majalis and R. Canina were established.
 Comparing the numerical values of loss on drying (not more than 10 %), total ash (not more than 5 %), extractable matter (not less than 9 %) and the quantitative content of total polyphenols (not less than 4 %) it was determined that both types of raw materials according to these indicators are almost indistinguishable.
 Conclusions. Loss on drying, total ash, extractable matter and content of total polyphenols of the root of R. majalis and R. canina do not have significant differences, that is why the root of both plant species can be used as medicinal plant raw materials such as “Rose root”.

The <strong>aim</strong> is to conduct a comparative pharmacognostical study of the series of roots of Rosa (R.) majalis Herrm. and Rosa (R.) canina L. with the establishment of diagnostic features of morphological and anatomical structure and boundary limits of numerical indicators of raw materials. <strong>Materials and methods. </strong>The fresh and dry raw materials were used to study the macroscopic microscopic features by microscope Delta optical BioLight 300 (Poland). Determination of total polyphenols was performed by spectrophotometry (on a spectrophotometer Optizen POP (Korea)) and HPLC (chromatograph an Agilent 1200 3 D LC System Technologies (USA)). <strong>Results.</strong> The morphological (nature of the surface (periderm) and fracture) and anatomical (color of cell walls and their cavities; location of the sclerenchyma; the presence of a crystalline coating of the sclerenchyma at the root of R. canina; of various elements of the remains of the tetraarchic conducting bundle in the center of the root) diagnostical features of roots of R. majalis and R. Canina were established. Comparing the numerical values of loss on drying (not more than 10 %), total ash (not more than 5 %), extractable matter (not less than 9 %) and the quantitative content of total polyphenols (not less than 4 %) it was determined that both types of raw materials according to these indicators are almost indistinguishable. <strong>Conclusions. </strong>Loss on drying, total ash, extractable matter and content of total polyphenols of the root of R. majalis and R. canina do not have significant differences, that is why the root of both plant species can be used as medicinal plant raw materials such as “Rose root”. The obtained data will be used in further research when creating methods of quality control of plant raw materials and phytomedicines

Full textAbstract:
The current study aimed to enhance the sustainable utilization framework of the underutilized Greek native Rosa canina L. (rosehip) germplasm as a potential novel crop that can deliver high-quality products with minimum environmental impact. The first part of the work includes asexual propagation trials on cuttings of two Greek R. canina genotypes, assessing the potential of various alternative rooting enhancers to the conventionally used indole-3-butyric acid (IBA), as affected by rooting substrate and cutting type. The propagation results showed commercially acceptable (>50%) rooting rates for 2500 ppm IBA, coconut water, rooting gel and aloe vera treatments and similar rooting attributes of root number and length, providing evidence for the feasibility of using alternative rooting enhancers. The second part of the work presents the results of an ongoing ex situ cultivation trial assessing the potential of a diversified organic fertilization regime against conventional fertilization on fruit size and yield, coupled with macro- and micro-nutrient concentration, in the leaves of four Greek R. canina genotypes. The results showed a genotype-specific response in rosehip fruit size and yield to fertilization, with the organic regime showing comparable results to the conventional fertilization. In addition, diverse patterns, depending on the element, of macro- and micro-nutrient content were measured in the leaves in both fertilization regimes, which were, however, genotype-dependent. Overall, the current study reports for the first time the potential of alternative rooting enhancers for commercial R. canina propagation coupled with the application of organic fertilization as a means of establishing a diversified cultivation protocol for underutilized R. canina germplasm. The current results can be employed to further facilitate a value chain creation for Greek rosehips as a raw material for use in the agro-alimentary and medicinal–cosmetic sectors.

Full textAbstract:
In view of the high diversity found in many groups of vascular plants on the Canary Islands, Spain, the genus Rosa (Rosaceae) is poorly represented comprising only two native taxa (R. canina, R. rubiginosa). For the first time, this study provides detailed data on distribution, morphology, chorology and status of the so-called ‘Teyde dog-rose’, a representative of the Section Caninae, which occurs exclusively in the subalpine zone of the Cañadas del Teide, Tenerife. A survey of both native stock and herbarium material yielded that this population, currently classified as common dog-rose (Rosa canina L.), is phenotypically close to continental representatives of the glaucous dog-rose (Rosa dumalis Bechst.), from which, however, it differs in several traits such as floral characters and leaf morphology. Consequently, the population is formally recognized as a distinct taxon, Rosa dumalis ssp. nov. teydensis Weller & H. Reichert. The new subspecies appears to be extremely rare in the wild, with a low number of individuals growing at scattered localities mainly at shady rocky walls and adjacent habitats in a restricted area of the southern Cañadas. Consequently, according to IUCN criteria the taxon must be regarded as Critically Endangered.

Full textAbstract:
The paper presents results of preliminary research carried out in 2011 in the area of two Protected Sites – CHA Jakub, CHA Kopec and Nature Reserve PR Mackov bok in the buffer zone of the Low Tatras National Park. Six native species and one native hybrid of roses were found there (1 from the Pimpinellifoliae section and 6 from the Caninae section) and their 13 varieties. The most numerous among them are Rosa canina var. dumalis Baker and R. × subcanina (H. Christ) R. Keller. Such great diversity of species and varieties insuch a small area (only 20.2 ha) proves considerable floristic richness, and occurrence of habitats preferred by roses.

Full textAbstract:
AbstractThirteen populations of wild roses (Rosa L.) growing in northern and central Tunisia have been used for studies on the discrimination between accessions and populations. Thirty-eight morphological characters related to the branches, prickles, leaves and corymbs were measured on the collected accessions to study the phenotypic diversity among and within species. Principal component and hierarchical cluster analyses (PCA and HCA) separated rose accessions into two distinctive groups and eight subgroups. A taxonomic interpretation of the morphological variability has shown that Tunisian rose populations belong to two sections (Synstylae and Caninae) of the genus Rosa. Moreover, they have been identified as seven separated taxa: R. sempervirens L., R. sempervirens var. submoshata Rouy., R. sempervirens var. prostrata Lindl. belonging to Synstylae section and R. canina L., R. agrestis Savi., R. micrantha Smith. and R. dumetorum Thuill. belonging to Caninae section. PCA and HCA proved that morphological characters used in taxonomic identification such as styles form, leaf and leaflets length, number of flowers by corymb, leaflet serration, presence of glands in leaflet, peduncle, receptacle and sepal have a high value of discrimination, and have been very successful in morphological identification.

Full textAbstract:
Nowadays, research on plant extracts has attracted increasing interest. The aim of this study was to compare phenolic profile, vitamin C, and carotenoid content, as well as the biological activities of five different rose species, including Rosa canina, R. corymbifera, R. micrantha, R. rubiginosa, and R. rugosa. These species had different morphological characteristics, with R. rugosa showing higher size of flower petals and higher weight of hips. The highest vitamin C content was found in hip extracts of R. rubiginosa and R. rugosa, which also showed the highest carotenoid amount. R. corymbifera showed the highest phenolic content. No significant antimicrobial activity of extracts containing phenolic compounds against different indicator strains could be detected. Cell monolayer integrity was not affected by treatments with the above-mentioned extracts of R. canina, R. micrantha, and R. rugosa at different concentrations for up to 24 h, while those of R. rubiginosa and R. corymbifera affected intestinal permeability at the highest concentration tested. The partial least squares regression analysis generated a predictive model correlating phenolic compounds with cell monolayer integrity, suggesting a relevant role for catechin, quercitrin, and p-coumaric acid. In conclusion, this study highlights how rose hips belonging to different species can have a diverse phenolic profile, differently influencing intestinal monolayer integrity.

Full textAbstract:
Rosehips of various Rosa spp. are well known for having human health-promoting compounds like mineral nutrients, vitamins, fatty acids, and phenolic compounds. However, little is known about rosehip characteristics which describe the fruit quality and may indicate appropriate harvest times. Our study evaluated the pomological (width, length, and weight of fruits, flesh weight, and seed weight), texture, and CIE colour parameters (L*, a*, and b*), chroma (C), and hue angle (h°) of rosehip fruits of Rosa canina, Rosa rugosa, and genotypes of Rosa rugosa ‘Rubra’ and ‘Alba’, harvested at five ripening stages (I–V). The main results revealed that genotype and ripening stage significantly affected parameters. The significantly longest (R. canina) and widest fruits (R. Rugosa) were measured at ripening stage V. Genotypes of R. rugosa ‘Rubra’ and ‘Alba’ had significantly higher fruit and flesh weights at ripening stage V. Rosehips of all investigated genotypes expressed darkness (lower L*) during ripening, and had the highest hue angle h° values at ripening stage I while the lowest was at stage V. The significantly lowest skin elasticity of rosehips was found at stage V. However, R. canina was distinguished by the highest fruit skin elasticity and strength. As our results show, the desired pomological, colour, and texture features of various species and cultivars rosehips can be optimised according to the harvest time.

Full textAbstract:
The morphology of pollen grains of 16 species from the <em>Rosa </em>L. genus were studied (i.e. <em>R. agrestis</em>, <em>R. canina</em>, <em>R. dumalis</em>, <em>R. gallica</em>, <em>R. inodora</em>, <em>R. jundzillii</em>, <em>R. kostrakiewiczii</em>, <em>R. majalis</em>, <em>R. micrantha</em>, <em>R. mollis</em>, <em>R. pendulina</em>, <em>R. rubiginosa</em>, <em>R. sherardii</em>, <em>R. tomentosa</em>, <em>R. villosa</em>, and <em>R. zalana</em>). The material came from 16 native localities of those species in Poland. The measurements are based on at least 30-50 randomly selected, fully developed pollen grains per specimen. In total, 500 pollen grains were examined. They were analysed for 13 quantitative features of pollen grains and exine sculpturing and the following qualitative traits: outline, shape, "operculum" structure. The diagnostic features of pollen grains of studied species were: length of polar and equatorial axes and length of ectocolpi. The above-mentioned pollen grain morphological features make isolation of one species possible: <em>R. gallica</em>. <em>R. gallica </em>is distinguished for its highest values of the length of polar and equatorial axes, and the length of ectocolpi. The obtained analytical results of operculum and exine sculpture features, considered as diagnostic, corroborated only slightly their priority significance for the isolation of the examined species and sections. The collected data failed to confirm fully the current taxonomical division of the <em>Rosa </em>genus into sections (only section <em>Gallicanae</em> from <em>R. gallica </em>is isolated) as well as consanguinity relationships between the examined species from the <em>Caninae </em>section. On the dendrogram, both species closely related with each other as well as those from other developmental lines were found in the same group. These equivocal results are by no means surprising because the <em>Caninae </em>section is the most polymorphic group in the <em>Rosa </em>genus, and contemporary <em>Caninae </em>are of the nature of a swarm of <em>R. canina </em>hybrids as a link combining all taxons of the section.

There is great evidence regarding the beneficial influence of rose hips on human and animal health. In this respect, fruits of native populations of Rosa spp. collected from the northeastern part of Romania (400-1060 m altitude) were assayed for nutritional and some morphological properties, in order to select the best genotypes. The results show a great quantitative variability of analyzed genotypes, regarding dimensions and biochemical indicators as follow: ascorbic acid: 866.91 mg/100 g fw (R. rubiginosa), 615.98 mg/100 g fw (R. caesia); carotenes: 34.95 mg/100 g fw (R. subcanina), 24.64 mg/100 g fw (R. nitidula); protein content: 0.47 g/100 g fw (R. micrantha), 0.25 g/100 g fw (R. caesia); total sugars: 17.63 g/100 g fw (R. andegavensis), 11.55 g/100 g fw (R. caryophyllacea). The fruits length, width and dry weight were: 25 mm (R. canina), 12 mm (R. micrantha), 16.5 mm (R. corymbifera), 8 mm (R. micrantha) and 25% dry weight (R. rubiginosa), 38% dry weight (R. nitidula), respectively. The present study demonstrates the existence of a rich rose germplasm source in north-east area, with good biotechnological fruit quality, which recommends them as functional foods according to their chemical contents (R. rubiginosa, R. vosagiaca, R. subcanina, R. canina and R. caryophyllacea) and also as sources for natural colorants in food technology.

Full textAbstract:
This study delves into the chemical and genetic determinants of petal color and fragrance in Rosa canina L., a wild rose species prized for its pharmacological and cosmetic uses. Comparative analysis of white and dark pink R. canina flowers revealed that the former harbors significantly higher levels of total phenolics (TPC) and flavonoids (TFC), while the latter is distinguished by elevated total anthocyanins (TAC). Essential oils in the petals were predominantly composed of aliphatic hydrocarbons, with phenolic content chiefly constituted by flavonols and anthocyanins. Notably, gene expression analysis showed an upregulation in most genes associated with petal color and scent biosynthesis in white buds compared to dark pink open flowers. However, anthocyanin synthase (ANS) and its regulatory gene RhMYB1 exhibited comparable expression levels across both flower hues. LC-MS profiling identified Rutin, kaempferol, quercetin, and their derivatives as key flavonoid constituents, alongside cyanidin and delphinidin as the primary anthocyanin compounds. The findings suggest a potential feedback inhibition of anthocyanin biosynthesis in white flowers. These insights pave the way for the targeted enhancement of R. canina floral traits through metabolic and genetic engineering strategies.

Full textAbstract:
Abstract In this study, the leaf epidermal characters of thirteen taxa of the genera Rosa L. and Rubus L. belonging to the family Rosaceae, which grows naturally in the Kurdistan Region of Iraq, was investigated via light microscopy. All taxa have the type of anomocytic stomata on the abaxial surface, and no stomata are present on the adaxial surface. Within the genus Rubus, among eighteen anatomical characters examined, only three characters are valuable at the species level, such as the anticlinal wall patterns on the adaxial and abaxial surfaces and the shape of the epidermal cells on the abaxial side. In Rosa, the shape of the epidermal cells on the abaxial surface varies from polygonal and polygonal-slightly irregular to irregular, and the variety R. canina var. deseglsei is recognized by the abaxial surface’s anticlinal wall pattern and the epidermal cells shape from other vanities of R. canina. Stomatal density as a range and stomata index could be valuable two diagnostic features for separating R. hemispharica from the remaining taxa of the genus Rosa. The taxa of Section: Pimpinellifoliae can be separate by the patterns of anticlinal walls of the abaxial surface from the remaining taxa of Sections: Caninae and Gallicanae within Subgenus: Rosa under study. According to our findings, some leaf epidermal characteristics and stomata are advantageous for distinguishing the various taxonomic ranks of the genera Rosa and Rubus family Rosaceae.

In the study, the macro and micro elements and fatty acid contents in rose seeds, which are generally evaluated in the waste category, were determined. Among the plants belonging to these taxa, only the registered varieties belonging to four taxa were used, while the others were genotypes. The plant materials of the study include rosehip (R. canina L.), Yildiz variety of rosehip (R. canina L. cv ‘Yildiz’), Syrup rose (R. heckeliana Tratt. subsp. vanheurckiana), Austrian briar (R. foetida Herrm.), lax rootstock [R. caesia Sm. (Syn: R. laxa Retz.)], wild rose [R. montana subsp. woronovii Chaix subsp. woronovii (Lonacz) Ö. Nilsson L.], hybrid landscape roses (R. x hybrida) and Hosap rose [R. pisiformis (Christ) D.] taxa. It was determined that the contents of nitrogen, potassium, phosphorus, magnesium and calcium of the macro elements examined in the seed samples differed statistically from each other. The seeds of different Rosa L. species examined within the scope of the research can be considered as one of the fruit oil sources with its 3.71-10.01% oil content. The fatty acid contents were determined as follows: linoleic acid (ω6) contents in the taxa ranged from 41.63 to 50.11% with an average of 44.88%; oleic acid (ω9) ranged from 20.80 to 30.27% with an average of 24.95%; linolenic acid (ω3) varied between 14.00-28.51% with an average of 19.20%; arachidic acid ranged from 0.75-1.63% and the average was 1.97%; eicosenoic acid ranged between 0.13-0.65% and averaged 0.33%; palmitoleic acid contents ranged from 0.08-0.60; behenic acid varied between 0.08-0.19% with 0.11% average. It was observed that the (ω3/ω6 ratio of the hybrid rose, which is especially used as a landscape rose and whose fruits are not evaluated, had an average value. R. canina ‘Yildiz’ cultivar showed a high (ω3/ω6 ratio, which is important in health terms. The high oleic acid contents found in these taxa are important results.

Stability of Rosa agrestis, R. canina, R. dumalis and R. rubiginosa regenerants after shoot tip cryopreservation was monitored with the use of biochemical markers and pollen quality assessment in matured plants cultivated in the field. The results of rosa pollen and hip evaluation revealed no significant differences between post-cryopreserved regenerants and control plants; however, variations in the assessed markers were noted between Rosa species. Analyses of hips confirmed high levels of vitamin C in these plants; the highest was observed in R. dumalis (750–870 mg/100 g fresh weight). High total antioxidant activity (TAC) was as follows: DPPH – 50–250 mM TE/100 dry weight, FRAP – 80–180 mM TE/100 g dry weight. The present study showed a high content of flavonoids (TFC) and phenols (TPC). Post-cryopreserved plants retained pollen specific for Caninae: numerous anthers, abundant pollen, poor pollen germination and viability and typical pollen morphology. This study demonstrates new tools for evaluating the fidelity of post-cryopreserved regenerants.

Shoot tips from in vitro plants of four rose species were cryopreserved by the droplet vitrification method. Optimized conditions involved exposure to loading solution for 20 min, then treatment with plant vitrification solution (PVS2) for 20 min (<em>Rosa agrestis</em>, <em>R. canina</em> and <em>R. dumalis</em>) or 30 min (<em>R. rubiginosa</em>) followed by freezing in liquid nitrogen. Survival rate ranged from 78.3 to 95.1%, depending on the species. Regrowth rate of shoot tips was 50.5% for <em>R. agrestis</em>, 63.2% for <em>R. rubiginosa</em>, 71.4% for <em>R. dumalis</em> and 78% for <em>R. canina</em>. The preculture of donor plants in a medium with 0.25 µM sucrose facilitated the isolation of shoot tips and increased regrowth rate after cryopreservation. Plant regeneration was carried out in Murashige and Skoog medium with 1 µM 6-benzylaminopurine, 1.5 µM gibberellic acid and 0.087 M sucrose. Plants regenerated from cryopreserved shoot tips did not display morphological alterations in comparison with non-cryopreserved shoot tip – derived plants.

Abstract This study aimed to explore the ethnopharmacological use of Rosa spp. on the Vlasina plateau, a rural region in southeastern Serbia with limited healthcare coverage, and to conduct phytochemical and pharmacological analyses of these species. The ethnopharmacological survey was conducted using semi-structured interviews. After identifying the three species utilized (R. dumalis Bechst., R. canina L., and R. corymbifera Borkh.), a phytochemical analysis was performed to assess their vitamin content and phenolic composition using spectrophotometric and UHPLC-MS/MS techniques. Pharmacological activities of rose hips were evaluated through in vitro antimicrobial testing against enteric pathogens, antioxidant activity using DPPH and ABTS radical scavenging assays, protein denaturation inhibitory activity, and cytotoxic activity against human cervical adenocarcinoma (HeLa) cells. The most frequently cited ethnopharmacological application was for treating chills, followed by dietary use and managing conditions such as diarrhea, dry cough, abdominal pain, and urinary issues. In terms of phenolic phytochemicals, rosmarinic acid predominated among phenolic acids in all three species, whereas catechin was the dominant flavonoid in R. dumalis and isoquercitrin in R. canina and R. corymbifera hips. The highest ascorbic acid and α-tocopherol contents were found in the rose hips of R. dumalis (235.79 and 1.80 mg/100 g FW, respectively). R. dumalis exhibited the highest radical scavenging, protein denaturation inhibitory, and cytotoxic activities, while all three species showed mild antimicrobial activity. The study provides valuable insights into the potential health benefits of Rosa species but is limited by its reliance on traditional knowledge and laboratory tests. Therefore, future research should focus on clinical trials to confirm their efficacy and safety. Overall, the results could pave the way for developing innovative pharmaceutical and nutritional products inspired by traditional knowledge.

Background: Rosehips, the fruits of Rosa species, are well known for their various health benefits like strengthening the immune system and treating digestive disorders. Antioxidant, anti-inflammatory, and cell regenerative effects are also among their health enhancing impacts. Rosehips are rich in compounds having antioxidant properties, like vitamin C, carotenoids, and phenolics. Methods: Total polyphenol content (Folin-Ciocalteu’s method), and in vitro total antioxidant capacity (ferric-reducing ability of plasma, FRAP) in rosehips of four Rosa species (R. canina, R. gallica, R. rugosa, R. spinosissima) were determined and compared. Ripe fruits were harvested at two locations. Water and ethanolic extracts of dried fruit flesh were analyzed. Results:R. spinosissima had the highest total phenolic content and antioxidant capacity, significantly higher than the other investigated Rosa species. Both parameters were reported in decreasing order for R. spinosissima > R. canina > R. rugosa > R. gallica. Ethanolic extracts of rosehips showed higher phenolic content and antioxidant activity than water extracts. Antioxidant properties were influenced by the growing site of Rosa species. Conclusions: This study indicates that R. spinosissima exhibited the greatest phenolic and antioxidant content, and therefore can be used as a reliable source of natural antioxidants, and serve as a suitable species for further plant breeding activities. Furthermore, investigations of various Rosa species for their antioxidant properties may draw more attention to their potential as functional foods.

Cornus mas L. (Cornaceae) and Rosa canina (Rosaceae) are plant species growing in Turkey naturally. The fruits of both plants are rich in anthocyanins, phenolics and vitamins and used for production of traditional foods such as syrup, juices, jam and marmalade. The antimicrobial activity and some bioactive contents of extracts obtained from fresh and dried fruits of C. mas and R. canina were investigated in this study. Also, as a result of GC-MS analysis of fresh and dried fruit extracts of C. mas and R. canina, varying numbers of fatty asits were determined. The major fatty asits in the extracts of both species were determined as varying proportions of palmitic, oleic and linoleic asit. Bioactive substance contents and antimicrobial activities were varied according to the extraction method. The methanolic extraction (dried fruits) so was more productive than that of water (fresh fruits). Antimicrobial activities of the plant samples were tested by well diffusion assay using 8 bacteria and one yeast. According to the results, both of the plant samples showed an inhibition on whole test microorganisms in varying range but B. subtilis and MRSA.

Using high-performance liquid chromatography/mass spectrometry, leaf and petal phenolic profiles of four rose (Rosa) species (R. canina, R. glauca, R. rubiginosa, R. sempervirens) traditionally used for medicinal purposes and three modern rose cultivars (Rosarium Uetersen, Ulrich Brunner Fils, Schwanensee) were determined. An abundance of phenolic constituents was identified: seven different anthocyanins and 31 flavonols in petals; 30 flavonols, 14 phenolic acids, and their derivatives; 15 flavanols; and 20 hydrolysable tannins in leaves. Additionally, petal color was measured with a colorimeter and regression analysis indicated a strong correlation between color parameter a* and total anthocyanin content. The content and composition of phenolic compounds varied significantly among species and cultivars and plant organs investigated. Distinct differences in the distribution of leaf phenolic compounds were observed, especially between Rosa species and modern rose cultivars. In general, leaves of analyzed species were richer in content of most phenolic groups and individual components compared with cultivars. Multivariate statistical analysis clustered the investigated species and cultivars into three distinct groups. Among species, leaves of R. canina stood out with their high and varied phenolic content. Conversely, leaves of the susceptible cultivar Schwanensee appeared most dissimilar as a result of their low levels of phenolic constituents.

Full textAbstract:
AbstractA method for screening Rosa accessions for their host suitability to Pratylenchus penetrans was developed. The best conditions were obtained in growth chambers with plants grown in sand, inoculated with 250 P.penetrans per 50 cm3 pot and fertilised weekly with 0.75 g/dm3 soluble fertiliser (containing 20% N, 20% P2O5, 20% K2O and balanced trace elements). Fifty days after nematode inoculation, these conditions permitted greater nematode multiplication than any other combination tested and also allowed good host development. When used for the screening of 21 Rosa accessions, these conditions revealed a large variation in host suitability. Least multiplication (Pf/Pi) was observed on R. virginiana (1.36) but this did not differ significantly from that on R. multiflora (2.87). The greatest Pf/Pi was on R. canina cv. Superba but this did not differ significantly from that on R. canina cv. Pollmeriana. The correlation of Pf/Pi with the nematode population and the number of eggs within the roots was significant; the percentage of nematodes outside roots was negatively correlated with Pf/Pi. The intermediate host status of R. corymbifera cv. Laxa, one of the most common rootstocks, was confirmed. Differences in host status became statistically significant when intra-accession variation was observed with a larger number of plants.

O Toxoplasma gondii, agente da toxoplasmose, encontra-se distribuído mundialmente. No presente estudo, determinou-se a prevalência do T. gondii nas espécies suína, bovina, ovina e eqüina oriundas de fazendas do município de Jaguapitã , através da imunofluorescência indireta para detecção de anticorpos da classe - IgG, considerando-se sororeagentes aqueles títulos maiores ou iguais a 1:64. Verificou-se uma prevalência de 24% em 267 amostras de suínos, 25,8% em 400 amostras de bovinos, 51,8% em 228 amostras de ovinos e 12,1% em 173 amostras de eqüinos. Com relação às faixas etárias, apenas os ovinos e suínos apresentaram diferenças estatísticas significantes, aumentando a soropositividade com as idades, porém, não se verificaram diferenças estatisticamente significativas com base no sexo de nenhuma das espécies animais estudadas. Obtiveram-se correlações entre os títulos de anticorpos interespécie, positivas e significativas, sendo que apresentaram importância epidemiológica aquelas entre as espécies humana-canina (r=0,64 p=0,05), humana-felina (r=0,78 p=0,01), canina-suína (r=0,96 p=0,0001), bovina-ovina (r=0,82 p=0,006), bovina-eqüina (r=0,89 p= 0,001) e ovina-eqüina (r=0,92 p=0,0004), demonstrando que as espécies hominívoras, carnívoras e herbívoras estariam expostas avias de transmissão comuns. Os resultados demostraram a elevada prevalência da toxoplasmose na população estudada e, conseqüentemente, o alto risco da carne como via de transmissão para o homem, quando ingerida crua ou mal cozida.

The article presents the data of the biochemical composition of the fruits of wild roses species, laboratory studies of which were conducted for the first time in Volgograd. Special attention is paid to the fact that wild roses is the one of the most important genera in the world and has an economic value in the biological, floriculture, pharmaceutical and cosmetic industries. It has been established that the difficulties of seed propagation of wild roses in arid conditions are primarily related to the peculiarities of their physiology, biochemistry and morphology. The objects of research were species with different areas of natural distribution: R. rugosa Thunb., R. cinnamomea L., R. spinosissima L., R. canina L., Ribes aureum Pursh., growing in collection areas of the Federal Research Centre for Agroecology, Complex Reclamation and Protective Afforestation. The article analyzes the indicators of weather conditions. The degree of demand for soil fertility and light revealed the most low-demand species: R. aureum, R. cinnamomea, R. rugosa and R. spinosissima. The authors found that all the studied species had good growth and development during the observation period. The amino acid composition of wild roses and currant fruits was determined using the capillary electrophoresis system "Drops" at a wavelength of 250 nm and allowed us to identify the most valuable species in terms of their biochemical composition. Analysis of the biochemical value of fruits found that the highest amount of protein, calcium, raw fiber, iodine and phosphorus differs type R. cinnamomea from the section of high-vitamin species and R. canina.

La ehrlichiosis monocítica canina (EMC) es una enfermedad causada por la bacteria intracelular obligada Ehrlichia canis (Rickettsiales, Anaplasmataceae). La EMC es de importancia en salud animal por ser considerada de alta mortalidad en caninos domésticos, con distribución mundial; con síntomas inespecíficos como fiebre alta, depresión, letargia, anorexia y signos clínicos como linfoadenomegalia, esplenomegalia y trombocitopenia con tendencia hemorrágica, por lo que su diagnostico es un desafío en el entorno clínico. Ehrlichia canis es transmitida a un hospedador susceptible por ninfas y adultos de la garrapata Rhipicephalus sanguineus sensu lato. El taxón R. sanguineus s.l. representa un complejo de especies asociadas a caninos domésticos con distribución cosmopolita y particularmente en la región Neotropical se reconocen dos linajes: tropical y templado. El linaje templado, que representa a R. sanguineus sensu stricto, siendo el límite geográfico que separa ambos linajes una zona ecotonal situada entre 24 ° y 25 ° de latitud sur. En condiciones experimentales, R. sanguineus s.s. (linaje presente en la región centro de Argentina) demostró no tener competencia vectorial para transmitir E. canis (cepa Jaboticabal, Brasil) pero si R. sanguineus s.l. del linaje tropical. Sin embargo, estudios recientes han determinado molecularmente la infección con E. canis en muestras de sangre de perros con diagnóstico presuntivo de EMC en la provincia de Buenos Aires, dónde prevalece R. sanguineus s.s. Además, poblaciones de R. sanguineus s.l. (LT) y R. sanguineus s.s. de las provincias de Formosa y Buenos Aires, respectivamente, se detectaron naturalmente infectadas con E. canis. El presente informe de caso es el primer reporte de caso confirmado de EMC por E. canis en un canino de la ciudad de Rafaela, Santa Fe, área endémica de R. sanguineus s.s.

Full textAbstract:
The volatile oils of R. canina flowers were isolated by hydrodistillation (HD) and traditional dry distillation (DD) and analyzed by HRGC-FID and GC-MS. Compared to HD, DD at 50°C leads to the isolation of high quality oil which contains the highest content of oxygenated compounds (83%). The main components are the 2-phenethyl alcohol and eugenol. The percentage of the 2-phenethyl alcohol, a highly desirable component in rose oil, was significantly higher (58.4%) in DD extract when compared to that of HD one (13.6%). As temperature increased (100°C) during DD, the oil quality decreased. The most significant changes were observed in 2-phenethyl alcohol percentage (4.5%). Moreover, an increase of alkanes/alkenes and the production of furan derivatives were observed. So, DD at moderate temperature (50°C) seemed more suitable to improve the volatile oil quality and hence, to make more value of R. canina.

R. canina L., H. rhamnoides L. and P. spinosa L. species are used traditionally as medicinal plants due to phytotherapeutical and nutritional potential of fruits. The aim of this study is to identify and quantify the catechin and epicatechin in branches of these species, using qualitative (HPTLC) and quantitative (HPTLC densitometry) methods. HPTLC fingerprinting of crude methanolic extracts showed specific peaks, with different Rf values, corresponding to catechin (at Rf 0.46) evidenced in branches of all three species and epicatechin (at Rf 0.43) highlighted only in samples of P. spinosa. The quantitative evaluation by HPTLC densitometry indicated the amount of catechin in branches of R. canina (0.17% g/g in dried plant material), H. rhamnoides (0.10% g/g in dried plant material) and P. spinosa (0.25% g/g in dried plant material) and the amount of epicatechin in branches of P. spinosa (0.22% g/g in dried plant material). These vegetal species can be considered a new source of catechins.

Full textAbstract:
This study was conducted to determine the change of fatty acids ratios of some rose hip species seeds in different harvest times. Seeds of five genotypes belonging to rose hip species (Rosa sp.) were used in the study. The fruits of species were harvested in six different ripening times and analyzed. Total oil analysis was performed for the fifth harvest only, which was determined as the optimal harvest time. As a result; total oil ratio of rose hip seeds varied as 5.22 and 6.62 g/100g respectively for accessions of Rosa dumalis (MR-12 and MR-15), 6.37 g/100g for R. canina (MR-26), 5.00 g/100g for R. dumalis ssp. boissieri (MR-46) and 5.29 g/100g for R. villosa (MR-84). Eleven fatty acids were determined in rose hip seeds. Among these fatty acids linoleic, oleic, linolenic, palmitic and stearic acids respectively had high ratio. Saturated fatty acids ratio (SFAs) was the highest in R. canina (MR-26) and the lowest in R. dumalis (MR-12); monounsaturated fatty acids ratio (MUFAs) was the highest in R. dumalis (MR-12) and the lowest in R. dumalis ssp. boissieri (MR-46); polyunsaturated fatty acids ratio (PUFAs) was the highest in R. dumalis ssp. boissieri (MR-46) and the lowest in R. dumalis (MR-12). Mono and polyunsaturated fatty acid contents obtained in this study was high; the change of fatty acid profile in the studied species in relation to harvest time was significant for some species and insignificant for others. A conclusion was reached that it is important to pay attention to qualitative and quantitative properties of seeds when conducting studies about rose hip improvement.

Paz (zona noroeste del Área Metropolitana de Buenos Aires –AMBA-). Se colectaron 32 garrapatas, siendo determinadas taxonómicamente como R. sanguineus s. l. (30 larvas y 2 ninfas). Mediante una PCR inicial para la familia Anaplasmataceae para un fragmento del gen ARNr 16S, resultaron positivas un grupo de 10 larvas y una ninfa. Dichas muestras positivas también fueron amplificadas mediante una PCR para un fragmento del gen dsb del género Ehrlichia, y posteriormente secuenciadas, resultando en un 100% de identidad con E. canis. Los especímenes de R. sanguineus s.l. positivos para E. canis fueron estudiados mediante una PCR para del gen mitocondrial 16S de garrapatas del grupo Metastriata, demostrándose su pertenencia al linaje templado de R. sanguineus s. l. Los estudios experimentales y los antecedentes epidemiológicos relacionan E. canis con R. sanguineus s. l. del linaje tropical, pero considerando que el único linaje de R. sanguineus detectado en AMBA ha sido el LTe, es necesario continuar investigando para dilucidar el mecanismo de transmisión y la dinámica vectorial en esta área.

The Rosa is one of the most diverse genera in the plant kingdom and, in particular, its fruits have been used for multiple purposes in different parts of the world for centuries. Within the genus, Rosa canina and Rosa dumalis are, economically, the most important species and dominate Rosa fruit production. In this study, some important fruit and shrub traits of ten Rosa canina and ten Rosa dumalis ecotypes collected from rural areas of Kars province, located in the east Anatolia region of Turkey were investigated. We found significant differences among ecotypes in most of the morphological and biochemical traits. The ecotypes were found between 1446–2210 m altitude. Fruit weight and fruit flesh ratio ranged from 2.95 g to 4.72 g and 62.55% to 74.42%, respectively. SSC (Soluble Solid Content), Vitamin C, total phenolic, total flavonoid, total carotenoid, and total anthocyanin content of the ecotypes ranged from 16.9–22.7%, 430–690 mg per 100 g FW (fresh weight), 390–532 mg gallic acid equivalent per 100 g FW, 0.88–2.04 mg per g FW, 6.83–15.17 mg per g FW and 3.62–7.81 mg cyanidin-3-glucoside equivalent per kg, respectively. Antioxidant activity was determined to be between 19.7–34.7 mg ascorbic acid equivalent per g fresh weight. Rosa ecotypes contained chlorogenic acid and rutin the most as phenolic compound. Our results indicated great diversity within both R. canina and R. dumalis fruits.
