Abstract:

The pollen of 15 genera and 36 species of the family Agavaceae were studied, based on Hutchinson' s classification. Observations were made with LM and SEM. Different taxonomical classifications are reviewed considering pollen morphology, geographical distribution, chromosome number and ovary position. From palynological point of view, Dahlgren et al., last classification agrees with the results obtained. Pollen samples studied show two levels of morphological behaviour: at an interespecific level there is little or no variation and at a generic level the following patterns are observed: a) semitectate and mainly monosulcate: Agave, Beschorneria, Dasylirion, Furcraea, Hesperaloii, Manfreda and Polianthes sometimes disulcate (Agavaceae, Agavoideae); b) tectate-perforate and monosulcate: Yucca (Agavaceae, Yuccoideae) and Dracaena americana (Dracaenaceae); c) tectate perforate to microreticulate and monosulcate to disulcate: Beaucamea, Calibamis and Nolina (Nolinaceae); d) intectate verrugate and monosulcate: Hasta (Funkiaceae); e) semitectate to tectate perforate and trichotomosulcate: Phormium (Phormiaceae); f) fosulate and monosulcate: Cordyline (Asteliaceae) and Dracaenafragans (Dracaenaceae) and g) psilate and ulcerate: Sansevieria (Dracaenaceae).

Abstract:

Draceana cinnabari (Dracaenaceae) is traditionally used in the treatment of wounds, leucorrhea, fractures, and diarrhoea. Herein, we performed a pre-clinical safety evaluation of extract of Draceana cinnabari resin on Spradgue Dawley rats. Toxicological codicil of the extract was carried out following OECD guidelines 423 and 407, with minor changes. DC resin methanol extract administered to the rats by oral gavage at 50, 500, 1500, and 2500 mg/kg body weight daily up to 28 days to male and female rats. Herbal extract could most likely be very much endured up to the dose 2000 mg/kg body weight and could be named Category 4. Oral toxicity studies confirm that Draceana cinnabari has no therapy-related demise or toxic signs on rats. Therefore, the resin, ought to be suitably considered for additional research for its medicinal and therapeutic efficacy.

Abstract:

Las invasiones biológicas se consideran en la actualidad como uno de los principales factores que condicionan la pérdida de biodiversidad en el planeta. En las últimas décadas, se ha incrementado el número de especies exóticas/invasoras detectadas en España. Este es el caso del picudo negro (Scyphophorus acupunctatus), un coleóptero (familia Curculionidae) originario de América, especializado en el consumo de plantas de las familias Agavaceae y Dracaenaceae. Detectado por primera vez en España en 2007, en Barcelona, ha sufrido una amplia expansión por todo el arco Mediterráneo. A partir de la recopilación de citas obtenidas de diferentes bases de datos, así como de otras obtenidas por los autores, se presenta una actualización de la distribución de esta especie para la España peninsular, discutiendo su potencial invasor. Biological invasions are considered one of the main factors conditioning the loss of biodiversity on the planet. During the last decades an increase in the number of exotic/invasive species has been detected in Spain. This is the case of the agave weevil (Scyphophorus acupunctatus), an American coleoptera (Curculionidae family) specialized in plants of the families Agavaceae and Dracaenaceae. It was detected for the first time in Spain in Barcelona in 2007. Since then it has suffered a wide expansion throughout the Iberian Mediterranean arc. From the compilation of citations obtained from different databases, as well as others obtained by the authors, an update of the distribution of this species is presented for peninsular Spain. We also discussed its invasive potential.

Abstract:

AbstractPhytochemical investigation of the aerial parts ofSansevieria trifasciata, one of the most common Dracaenaceae plants, has resulted in the isolation of a new dihydrochalcone derivative named trifasciatine C (1), four previously unreported steroidal saponins as two pairs of inseparable regioisomers: trifasciatosides K/L (2/3), M/N (4/5), together with the known 1,2-(dipalmitoyl)-3-O-β-D-galactopyranosylglycerol (6), aconitic acid (7), and 1-methyl aconitic acid (8). Their structures were elucidated mainly by extensive spectroscopic analysis (1D and 2D nuclear magnetic resonance) and high-resolution electronspray ionization-mass spectrometry, as well as chemical methods and comparison of their spectral data with those of related compounds. Compounds2/3and4/5were evaluated for their antiproliferative activity on Hela cells, and no significant effect was observed.

Abstract:

Background: The phytochemical screening and antidiabetic activities of the methanol leaf extract and fractions of Sansevieria liberica Ger. and Labr. were investigated.Objectives: To identify the phytoconstituents present and evaluate the anti-diabetic activity of the leaf of S. liberica Ger. and Labr.Material and Methods: A 1.2 g of the pulverized leaf was cold macerated in methanol to obtain 240 g of the crude extract (CE), fractionation was done using n-hexane, ethylacetate and butanol. The CE and the fractions were screened for phytochemical and antidiabetic analysis using standard procedures. Diabetes was induced by intraperitonial injection of alloxan. The blood glucose levels were analyzed as indices of diabetes.Results: After 24 hours, alloxan increased the blood glucose level of rats indicating hyperglycaemia. Treatment of the rats with the extract and fractions reduced the blood glucose level within 3 to 7 days of treatment. The standard antidiabetic, metformin (500 mg/kg) also showed similar effect. Extracts (250 and 500 mg/kg) of the crude extract decreased significantly (p<0.05) the blood glucose level. The antidiabetic potency of the extract and fractions were in the order of CE ˃ ethylacetate fraction > n-Hexane fraction > butanol fraction. The phytochemical screening of the extract and fractions revealed the presence of flavonoids, steroids, alkaloids, glycosides etc.Conclusions: From the findings, S. liberica leaf posses antidiabetic activity which may be due to the phytochemical constituents present, and this justifies its use by local users as traditional remedy for diabetes mellitus.

Abstract:

The pure Soqotri resin of Dracaena cinnabari Balf.f. (Dracaenaceae) has no volatile smell due to its low content of volatile constituents. Although it is insoluble in n-Hexane, we found that the resin, when suspended in n-Hexane within five days at 5 °C, led to the extraction of a small portion of a single volatile liquid constituent, which was identified by GC-MS as sesquiterpene β-caryophyllene. This method of extracting the volatile constituents using hexane under cooling is very suitable for resins of the Dracaena species because these resins usually contain very few volatile terpenes and/or non-terpenes, and they may contain only one volatile terpene per resin as this study result. β-Caryophyllene was identified and separated for the first time from the Soqotri standard resin of Dracaena cinnabari. Therefore, β-caryophyllene, as a new chemical property, can support to evaluate the purity of the Soqotri resin. Moreover, a big mass of D. cinnabari resin can yield concentrated β-caryophyllene as a liquid extract for further pharmaceutical and nutraceutical applications.

Abstract:

We induced preferential allocation of Ca to two calcium oxalate (CO) sinks in immature leaf tissues of D. sanderiana: subepidermal extracellular deposits and intracellular raphides. Allocation was affected by exogenous Ca levels. Two groups of rooted cuttings were termed Ca-deficient and non-deficient. The first group consisted of cuttings that had been deprived of Ca for 18 months, and, the second, cuttings rooted under standard horticultural conditions. All plants were grown in liquid medium supplemented with 100 ppm of potassium nitrate and subjected to 0, 3, or 7mm Ca from calcium acetate. The most striking feature of Ca-deficient plants grown in 0 mm Ca was the absence of intracellular raphides in the leaf primordia. The largest number of intracellular raphides developed in Ca-deficient plants grown in 7 mm Ca. The number of extracellular crystals in Ca-deficient plants grown in Ca-supplemented solutions versus non-supplemented were similar, but crystals were considerably smaller in non-supplemented plants. Total number of extracellular crystals per epidermal cell did not differ significantly between plants in all treatments. This implies that nucleation sites are pre-determined and finite in number. In contrast, the number of intracellular raphides was highly variable. In terms of Ca prioritization, the extracellular crystals took precedence over intracellular raphides, and this was most obvious in Ca-deficient plants. The significance of this research is that the extracellular crystals represent Ca sinks with limited induction capacity compared to intracellular Ca sinks. Plants with genetic predisposition for intracellular CO crystal formation may be able to respond favorably to root environments with low Ca levels compared to species with limited capacity for intracellular CO deposition. Intracellular CO crystals, therefore, play an integral role in plant nutrition as Ca storage sinks.

Abstract:

The effect of 0, 3, and 7 mm Ca2+ on the allocation and deposition of Ca2+ into intracellular and sub-cuticular periplasmic calcium oxalate (CO) crystals was examined in leaf primordia of rooted cuttings of Dracaena sanderiana Hort. Sander ex M.T. Mast. Crystal development was monitored in two types of cuttings, those rooted in deionized water for 18 months and those rooted in Metro Mix 500 for 6 weeks. Response differed remarkably depending on the type of cutting. Cuttings rooted in deionized water deposited sub-cuticular crystals at the expense of intracellular crystals (raphides). The number of sub-cuticular crystals in leaf primordia of cuttings rooted in deionized water grown in solutions supplemented with either 0, 3, or 7 mm Ca2+ was similar, but crystals were considerably smaller in plants grown in 0 mm Ca2+. Sub-cuticular crystals appeared developmentally earlier in leaf primordia of all cuttings grown in either 3 mm or 7 mm Ca2+ than in cuttings rooted in deionized water grown in 0 mm Ca2+. This finding supports the premise that deposition of sub-cuticular crystals is modulated by Ca2+ levels and could be induced at an earlier ontogenetical stage by raising rhizospheric Ca2+ levels or delayed by lowering rhizospheric Ca2+ levels. The total number of sub-cuticular crystals per epidermal cell did not differ significantly between treatments implying that crystal nucleation sites are predetermined and finite in number. In contrast, the formation of intracellular raphides was highly variable and depended on Ca2+ concentrations. In terms of Ca2+ prioritization, sub-cuticular CO crystals took precedence over intracellular CO raphides.

Abstract:

The genus Dracaena has been placed in Agavaceae by most taxonomists. Recent work, however, has justified the placement in a separate family, Dracaenaceae. This study was initiated to examine the extracellular crystalline deposits in Dracaena and the possibility of this feature as a taxonomic trait of the genus. Fresh epidermal peels of five Dracaena species were observed under polarized light. Extracellular epidermal crystals were evident in all of them. The deposits were found between the cuticle and the outer primary epidermal cell wall. The crystal size varied from less than 1 μm to 5 μm along the long crystal axis. The size and quantity of the deposits varied between the species with largest and most numerous crystals in the cuticle of D. marginata and D. sanderiana. Dracaena deremensis, D. fragrans, and D. surculosa had smaller and less numerous crystals. The optical properties of the crystals were indicative of calcium oxalate monohydrate form which exhibited interference colors of second and third order. For comparison species of three members of Agavaceae were examined -Cordyline terminalis, Sansevieria trifasciata, and Yucca sp. No extracellular crystal deposits in the proximity of the epidermal wall were detected. Based on our observations, the genus Dracaena possessed an anatomical feature which could be used for identification. The existence of calcium oxalate crystals embedded in the cuticle was readily observable in fresh epidermal peels under polarized light.

Abstract:

The nature and limits of the Agavaceae have been controversial since its proposition in the last century. Here we analyze the sequences of the chloroplast gene rbcL of 9 species from the Agavaceae sensu Hutchinson (1934, 1959) along with 44 additional sequences, including 36 sequences from the Lilianae, and as outgroups 8 sequences of the Alismatanae and Arecanae. We present parsirmony, neighbor-joining and maximum likelihood analysis We identified three main evolutionary lines related to the Agavaceae as defined by Hutchinson. These lines encompass most of the Asparagales order as defined by Dahlgren et al. (1985): (i)Asparagus (Asparagaceae), Dianella (Phormiaceae), Hemerocallis (Hemerocallidaceae) and the Asphodelacea (Aloe, Haworthia and Kniphofia); (ii) Agavaceae sensu stricto, including Agave, Manfreda, Beschorneria, Hesperaloe and Yucca, the Asiatic genus Hasta (Funkiaceae) and the pantropical herb Chlorophytum (Anthericaceae); (iii) Sansevieria (Dracaenaceae), Danae (Ruscaceae) and the Nolinaceae (Nolina, Beaucamea and Dasylirion). According to our analysis other groups of species related to the Agavaceae sensu Hutchinson are: Bowiea (Hyacinthaceae), ledebouria (= Sci/la, Hyacinthaceae), Clivia (Amaryllidaceae), Lomandra (Dasypogonaceae), Xanthorrhoea (Xanthorrhoeaceae), Cyanastrum (Cyanastraceae) and the lridaceae (Iris, Orthosanthus and Anomatheca). We conclude that the Agavaceae, as proposed by Hutchinson (1934, 1959) is not a monophyletic group, although most of its species form the core of a larger clade that approximately corresponds (with the addition of the Iridaceae) lo the Asparagales as proposed by Dahlgren et al. ( 1985).

Abstract:

Dracaena cinnabari Balf. f. (Dracaenaceae) is an important plant endemic to Soqotra Island, Yemen. Dragon’s blood (Dam Alakhwin) is the resin that exudes from the plant stem. The ethnobotanical survey was carried out by semi-structured questionnaires and open interviews to document the ethnobotanical data of the plant. According to the collected ethnobotanical data, the resin of D. cinnabari is widely used in the traditional folk medicine in Soqotra for treatment of dermal, dental, eye and gastrointestinal diseases in humans. The resin samples found on the local Yemeni markets were partly or totally substituted by different adulterants. Organoleptic properties, solubility and extractive value were demonstrated as preliminary methods to identify the authentic pure Soqotri resin as well as the adulterants. In addition, the resin extracts and its solution in methanol were investigated for their in vitro antifungal activities against six human pathogenic fungal strains by the agar diffusion method, for antioxidant activities using the DPPH assay and for cytotoxic activity using the neutral red uptake assay. The crude authentic resin dissolves completely in methanol. In comparison with different resin extracts, the methanolic solution of the whole resin showed the strongest biological activities. It showed strong antifungal activity, especially against Microsporum gypseum and Trichophyton mentagrophytes besides antioxidant activities and toxicity against FL-cells. These findings confirm and explain the traditional uses of the resin for the treatment of skin diseases and mouth fungal infections.

Abstract:

Varicocele is a disease characterized by an abnormal dilation of the pampiniform plexus that drains the testis. The main objective of this work was to evaluate the curative effects of aqueous and ethanolic extracts of Dracaena arborea on some reproductive and antioxidant markers in rats with experimental varicocele. Following varicocele induction, rats (5 per group) were randomly partitioned into untreated varicocele, vitamin E-treated (150 mg/kg), aqueous extract-treated (500 mg/kg), and ethanolic extract-treated (100 mg/kg) animals. Two other groups served as normal and sham-operated. After 2 or 4 weeks of treatments, body and sex organ weights, spermatozoa characteristics, antioxidant status, NO level, sex hormones, and testis histology were measured. Animals with 3 weeks of varicocele showed a significant ( p < 0.05–0.001) decrease in body and sex organ weights, total proteins, sperm characteristics, testosterone concentration, SOD, catalase, and total peroxidase activities. An increase in the plasmatic FSH, LH, and testicular MDA and NO concentrations was also recorded. Moreover, marked disorganization of the testicular architecture was observed. Treatment with D. arborea significantly reversed these impairments due to varicocele. For instance, after 4 weeks, treatment with aqueous extract of D. arborea significantly ( p < 0.05–0.001) increased testes and epididymis weights, sperm viability (89.12 ± 1.09 vs 68.22 ± 1.42), sperm density (148.50 ± 2.59 vs 110.25 ± 2.51), and sperm motility (68.16 ± 2.39 vs 55.88 ± 3.20) in the left side, compared with varicocele-untreated rats. The extract also significantly ( p < 0.05–0.001) decreased malondialdehyde level (2.19 ± 0.04 vs 3.50 ± 0.13) but elevated catalase (0.97 ± 0.03 vs 0.55 ± 0.03), SOD (0.5 ± 0.03 vs 0.15 ± 0.03), and peroxidase (65.80 ± 2.9 vs 40.95 ± 2.44) activities. Present results showed that D. arborea extracts possess antioxidant effects and improve sperm quality in male rats with an existing varicocele.

The phylogenies show that Acorus calamus is the living plant more closely related to the ancestral monocotyledons. The different analyses identify three main evolutionary linages in the Agavaceae sensu Hutchinson: 1) One including the Agavaceae sensu stricto, (Agave, Manfreda, Beschorneria, Hesperaloe and Yucca) with Hasta (Funkiaceae) and Chlorophytum (Anthericaceae). 2) Other group that includes the Nolinaceae (Nolina, Beaucarnea and Dasylirion), Sansevieria (Dracaenaceae) and Danae (Ruscaceae). 3) A third group formed by the Asphodelaceae (Aloe, Haworthia and Kniphofia) and Dianella (Phormiaceae). These lineages include the majority of the Asparagales, as were defined by Huber (1969) and Dahlgren et al. (1985). A molecular clock was also estimated to obtain the divergence times among the groups related to the Agavaceae. A rate of 0.34x10-9 nucleotide substitutions per site per year was obtained. Using this calibration, a date for the origin ofthe true Agavaceae (separation between Agavaceae-Hosta) was estimated to be about 14 million years, for the separation of the Agavaceae-Nolinaceae of about 47 million years and for the origin of the Asparagales + Iridaceae + Cyanastraceae of about 84 million years. Nevertheless, these estimates should be regarded as preliminary.

Abstract:

A comparative foliar anatomical study of the invasive and non-invasive species of Dracaena in Obafemi Awolowo University Campus in Nigeria was carried out. A specific aim of the study was to determine the foliar and morphological traits in Dracaena mannii, which may be responsible for its invasive habit. The foliar anatomical traits were also used to describe the two studied Dracaena species. Fresh and matured leaves of D. mannii and D. arborea were collected and authenticated at the Herbarium of Obafemi Awolowo University (IFE). Quantitative and qualitative data were recorded for morphological traits, whereas scraping techniques were used to obtain the epidermal peels and photomicrographs of slides were taken for observing the anatomical traits. The presence of club-like glandular unicellular trichomes and papillose, high stomata index and frequency of epidermal cells per unit area strengthen the invasive habit of Dracaena mannii. The thin walls of the epidermal cells increase the intercellular flow of assimilates within D. mannii, which is also a notable invasive character.

Abstract:

In Nigeria, there is paucity of information on plants used to repel or kill mosquitoes despite the abundant plant species in the country’s tropical rain forests. Majority of available data are on the traditional use of plants for curative purposes. This study documents some plant species used for insecticidal or repellent purposes against mosquitoes in Nigeria. An ethno-botanical survey was carried out in four geo-political zones in the country using structured questionnaires and focus group discussion. A total of six plant species belonging to five families were reported in Delta state with Conyza Canadensis (Compositae) being the most utilized (50%) and Aspilia africana (Compositae), the least mentioned (5.60%). In Enugu state, a total of nine plant species belonging to eight families were mentioned by respondents with Aframomum melegueta the most utilised (26.09%) while Agava sisalana and Dracaena manii belonging to the families Agavaceae and Dracaenaceae were the least mentioned (1.09% each). A total of six plant species belonging to five families were reported in Kaduna State with Lantana camara belonging to the family Verbenaceae accounting for 58.82% of the utilised plant species for mosquito control while Ipomea asarifolia, Terminalia catappa and Citrullus vulgaris belonging to the families Convolvulaceae, Combretaceae and Cucurbitaceae respectively were the least utilized (5.88% each). Lagos State recorded the highest number of plant species (twenty five) belonging to eighteen families. Spondia mombin belonging to the family Lilaceae was the most mentioned (7.33%) while the least mentioned (0.37% each) were Magnifera indica, Baphia nitida and Pennisetum purpeum belongingto the families Anacardiaceae, Fabaceae and Poaceae respectively. There is a need for further investigation on these plant species as they may constitute potential sources of cidal and repellent compounds against a wide range of insect pests.

Abstract:

Plant poisoning is a health concern in many countries where plants are used either accidently, especially among children, or intentionally for purposes such as assassination, suicide, hunting, fishing and treating various diseases. Presently, despite the implementation of toxicology surveillance systems in many countries, plant poisoning continues to be a preventable cause of morbidity and mortality. In the Aden governorate of Yemen, there are no laws or regulations for the prevention of plant poisoning, despite the existence of several poisonous species in gardens, and as roadside trees planted by the local authority, or growing wildly in public areas. In addition, there is a lack of scientific studies on the risks of these poisonous plants. Therefore, we undertook this study, based on scientific review, to document and illustrate the botanical, geographical and toxicological characteristics of fourteen poisonous plants collected from different districts of Aden governorate. The documented poisonous species (6 species) belong to Apocynaceae followed by Fabaceae (2 species), whereas Aristolochiaceae, Cucurbitaceae, Dracaenaceae, Euphorbiaceae, Meliaceae, and Verbenaceae are represented by one species each. The toxic parts of the majority of studied poisonous species are the whole plant, latex, seeds, and fruits. Cardiotoxicity, cytotoxicity, gastrointestinal toxicity, and inflammation of skin and mucous membrane are the main clinical manifestations. They are caused by varying amounts of plant toxins such as cardiac glycosides in Calotropis procera, Cryptostegia grandiflora, Nerium oleander and Thevetia peruviana, and cytotoxic toxins such as toxalbumins in Abrus precatorius and Ricinus communis, aristolochic acids in Aristolochia bracteolate, and vinca alkaloids in Catharanthus roseus, as well as gastrointestinal toxins such as cucurbitacins in Citrullus colocynthis, and tannins in Caesalpinia pulcherrima. Inflammation of skin and mucous membrane is caused by calcium oxalate crystals in Calotropis procera latex, and soluble protein in Cryptostegia grandiflora latex. Moreover, Azadirachta indica caused a number of toxicities attributed partially to tetranortriterpenoids, while Sansevieria trifasciata toxicity was reported to be low. The significance of this work is to promote the awareness among the local authority to take legal actions against plant poisoning. In addition, it provides the physicians with scientific information for the diagnosis and treatment of poisoning by some plants. It is hoped that this study motivates researchers to conduct further research on poisonous plants throughout Yemen.

Abstract:

The subfamily Nolinoideae of Asparagaceae is an extremely morphologically heterogeneous group, which is comprised of seven lineages, formerly known as Eriospermaceae, Polygonateae, Ophiopogoneae, Convallarieae, Ruscaceae s.s., Dracaenaceae, and Nolinaceae from different families or even orders. Their drastically divergent morphologies and low level of molecular resolution have hindered our understanding on their evolutionary history. To resolve reliable and clear phylogenetic relationships of the Nolinoideae, a phylogenetic study was conducted based on transcriptomic sequencing of 15 species representing all the seven lineages. A dataset containing up to 2,850,331 sites across 2,126 genes was analyzed using both concatenated and coalescent methods. Except for Eriospermum as outgroup, the transcriptomic data strongly resolved the remaining six lineages into two groups, one is a paraphyletic grade including the woody lineages of dracaenoids, ruscoids, and nolinoids and a monophyletic herbaceous clade. Within the herbaceous group, the Ophiopogoneae + Theropogon is sister to a clade that is composed of Convallarieae and the monophyletic Polygonateae. Our work provides a first robust deep relationship of the highly heterogeneous Nolinoideae and paves the way for further investigations of its complex evolution.

Abstract:

The Floristic inventory of the swamp forest at Atan Ukwok was carried out using the Systematic and Transect Sampling Methods where the line transect was the main path of the forest and Sampling units were chosen along the path at a distance of 14m × 14m and 6 sampling plots were sampled. The frequency, density and abundance of the identified species were calculated using standard formulae. A total number of 61 species from 35 families were identified. The number of species recorded for the plant families were, Cyperaceae 5, Euphorbiaceae 4, Acanthaceae, Apocynaceae, Asteraceae, Aspidiaceae and Poaceae 3 each, Arecaceae, Caesalpiniaceae, Mimosaceae, Melastomataceae, Schizaceae, Thelypteridaceae and Verbanaceae 2 each and Athyriaceae, Costaceae, Dioscoreaceae, Dracaenaceae Gleicheniaceae Araceae, Davillianaceae, Malvaceae, Commelinaceae, Clusiaceae, Selaginellaceae, Combretaceae, Convolvulaceae, Colchicaceae, Fabaceae, Moraceae, Malvaceae, Lycopodiaceae and Rutaceae 1 each. The highest species frequency and density of 66.7% and 9.5% respectively was found in Setaria megaphylla and the highest abundance value of 50.0 was found in Dracaena arborea. The frequency percentage of the plant species showed that the forest is fast loosing vegetation due to the obvious encroachment of parts of it by the inhabitants of the community for the purpose of cultivation. This calls for concerted conservation measures in order to ensure the sustainable use of the floral diversity of the forest.

Abstract:

Abstract Background We investigated the effects of a polyherbal formulation prepared from the extracts of Mondia whitei (Periplocaceae), Dracaena arborea (Dracaenaceae), and Bridelia ferruginea (Euphorbiaceae) (MDB) on the sexual behavior of normal rats (NR) and prediabetic rats (PR). Methods Male Wistar rats were administered with drinking fructose solution (21%) or tap water for 16 weeks. After induction of prediabetic status, NR (n = 30) and PR (n = 30) were randomly distributed into 10 groups of six animals each and orally treated with distilled water (10 mL/kg), sildenafil citrate (5 mg/kg), or MDB (50, 100, or 500 mg/kg) for 21 days. Sexual behavior parameters per series (S) of ejaculation were evaluated on days 1, 7, 14, and 21. Results Drinking fructose solution (21%) induced prediabetic status in rats, characterized by a significant (p < 0.01) increase in glycemia by 43.41% compared with the control group. MDB improved sexual performances of NR and PR by increasing the mount frequency (MF) and the intromission frequency (IF) as well as the number of rats capable of ejaculating. For instance, the MF and the IF were significantly increased in animals administered with MDB for 7 (50 mg/kg, S1 and S2), 14 (100 mg/kg, S3), or 21 days (100 or 500 mg/kg, S2). This increase was more pronounced on days 7 and 14 in NR and PR treated with sildenafil citrate or MDB extracts, respectively. Conclusions The mixture of MDB improved sexual activity in NR and PR. This result may further justify the traditional use of these plants as sexual performance enhancers.
