Abstract:

Cotyledons of several collections of each taxon of Cucumis africanus Lindley f., C. anguria L. var. anguria, C. anguria var. longipes Meeuse, C. dipsaceus Ehrenb. ex Spach, C. metuliferus E. Mey ex Schrad., C. myriocarpus Naud., C. zeyheri Sond. (2x, 4x), and C. melo L. were surveyed using horizontal starch gel electrophoresis to characterize interspecific and intra-specific variation and to furnish preliminary phylogenetic information with regard to the cross-compatible group of wild African Cucumis species. Eight enzyme systems were studied: shikimate dehydrogenase, triose-phosphate isomerase, glutamic-pyruvic transaminase, glucose-phosphate isomerase, phosphogluconate dehydrogenase, isocitrate dehydrogenase, peptidase with phenylalanyl-L-proline, and phosphoglucomutase. All enzymes were polymorphic. Although C. anguria var. anguria accessions from Brazil and Ethiopia were similar, zymograms of C. anguria var. longipes were more similar to the C. melo collections. Results from var. anguria and var. longipes support previous data with regard to their varietal nature. The relative similarity among patterns of C. anguria var. longipes, C. metuliferus, and C. myriocarpus suggests a closer phylogenetic relationship than had previously been proposed. Isozyme similarities between C. anguria var. anguria, C. africanus, and C. dipsaceus suggest some phylogenetic affinities.

Abstract:

Wild Cucumis species have been divided into Australian/Asian and African groups using morphological and phylogenetic characteristics, and new species have been described recently. No molecular cytogenetic information is available for most of these species. The crossability between 5 southern African Cucumis species (C. africanus, C. anguria, C. myriocarpus, C. zeyheri, and C. heptadactylus) has been reported; however, the evolutionary relationship among them is still unclear. Here, a molecular cytogenetic analysis using FISH with 5S and 45S ribosomal DNA (rDNA) was used to investigate these Cucumis species based on sets of rDNA-bearing chromosomes (rch) types I, II and III. The molecular cytogenetic and phylogenetic results suggested that at least 2 steps of chromosomal rearrangements may have occurred during the evolution of tetraploid C. heptadactylus. In step 1, an additional 45S rDNA site was observed in the chromosome (type III). In particular, C. myriocarpus had a variety of rch sets. Our results suggest that chromosomal rearrangements may have occurred in the 45S rDNA sites. We propose that polyploid evolution occurred in step 2. This study provides insights into the chromosomal characteristics of African Cucumis species and contributes to the understanding of chromosomal evolution in this genus.

ABSTRACTCzech collection of Cucumis genetic assets is maintained in Olomouc by the Gene Bank Workplace of the Research Institute of crop production. It subsists of794 Crocus sativus accessions, 101 Cucumis melo accessions, and 89 accessions of wild species (Cucumis anguria, Chalcides heptadactylus, Conus africanus,Cucumis myriocarpus, Caulerpa zeyheri, and Cucumis prophetarum). Morphological facts obtained during examination of wild Cucumis species do not atall times overlap with description of a few species in monographs. The taxonomical range of some accession should be reconsidered. An internationaldiscrepate list for cultivated. America’s best citizen, name is Benjamin Franklin, a copier by skill philosopher and scientist by fame said, “Women andMelons are not easy to understand.” Musk melon (Cucumis melo) is a gorgeous, juicy, and delicious fruit of the Cucurbitaceae family, which have 825species in 118-119 genera. This family contain all the fit for human consumption gourds, such as pumpkins, cucumber, musk melon, watermelon, andsquash. Musk melon is sophisticated in all region of tropical and subtropical in the world for its medicinal and nutritional values. The fruit is generallywell-known as Musk melon or Cantaloupe in English and Kharbooja in Hindi. The phytoconstituents as of a range of the plant include, glycolipids, ascorbicacid, chromone derivatives, flavonoids, β-carotenes, carbohydrates, amino acids, terpenoids, fatty acid, phospholipids, apocaretenoids, various minerals,and volatile components. C. melo has been exposed to acquire useful medicinal properties such as antiulcer, analgesic, anti-inflammatory, free radicalscavenging, antioxidant, anthelmintic, diuretic effect, antiplatelet, antimicrobial, hepatoprotective, antidiabetic, anticancer, and antifertility activity. Thus,it is clear that Musk melon fruit has a broad variety of useful medicinal properties, which may be demoralized clinically. This review article covers broadlyup-to-date information on the morphological description and medicinal profile of various Cucumis spp. and Musk melon.Keywords: Musk melon, Cucumis spp., Antiulcer, Anioxidant.

Abstract:

Objective. To evaluate the phytochemical content and antioxidant potential of the acetone, aqueous, and methanol extracts of the fruit, leaf, and root of Cucumis africanus L.f. Methods. Total phenolic, flavonoid, and proanthocyanidin contents were evaluated using spectrophotometric methods. The free radical scavenging activity of the acetone, methanol, and aqueous extracts of the fruit, leaf, and root were evaluated against DPPH+, ABTS+, and phosphomolybdenum. Alkaloid and saponin contents were also determined. Results. The acetone extract of the fruit revealed the highest polyphenol content when compared with the other solvent extracts analyzed. Total phenol content of the parts tested ranged from 3.66 ± 0.17 to 44.98 ± 3.41, flavonoid content ranged from 4.63 ± 3.33 to 401.33 ± 7.89, and proanthocyanidin content ranged from 8.84 ± 2.65 to 504 ± 36.6. Significant amount of alkaloids present was observed in the fruits, leaf, and root (10.68 ± 0.68, 14.12 ± 1.67, and 12.15 ± 4.74), respectively, while saponin content was 33.33 ± 11.55, 26.67 ± 11.55, and 20.00 ± 0.00 for the fruit, leaf, and root, respectively. Solvent extracts showed significant antioxidant activity, with acetone showing highest antioxidant ability in correlation with the polyphenol contents. Based on the IC50 values, acetone extract of the root revealed the best DPPH radical scavenging ability, the leaf aqueous extract had the highest IC50 value for ABTS, and the methanol extract of the leaf was best for phosphomolybdenum assays. Conclusion. This study suggests that fruit, leaf, and root of Cucumis africanus could be a potential source of natural antioxidant and justifies its use in ethnomedicine.

Abstract:

The thermostable cucurbitacin A and B from mature fruit of wild cucumber (Cucumis myriocarpus) and wild watermelon (Cucumis africanus), respectively, are used in product development for various industries. Mature fruit from wild cucumber and wild watermelon suffer from high incidents of postharvest decays. Drying fruit at the recommended temperatures of 30 to 40 °C for medicinal plants resulted in molds developing on the material, with optimum temperature to prevent decays being at 52 °C. The influence of 52 °C and higher temperatures on active ingredients in the two fruit had not been documented. The objective of this study, therefore, was to determine the relative effects of increasing drying temperatures above the 52 °C standard on concentrations of cucurbitacin A and B in fruit of wild cucumber and wild watermelon. Fruit pieces were oven-dried at 52, 60, 70, 80, 90, and 100 °C for 72 hours. Relative to 52 °C, higher temperatures resulted in 25% to 92% less cucurbitacin compared with the maximum produced at 60 °C. In contrast, relative to 52 °C, higher temperatures reduced concentrations of cucurbitacin B by 47% to 86%. In conclusion, the compromise temperature of 52 °C for preserving fruit pieces in wild cucumber and wild watermelon from decay should also be viewed as the optimum temperature for preserving cucurbitacin A and B.

Abstract:

Este artigo apresenta uma pesquisa sobre os Cucumbis Carnavalescos. Esses grupos alcançaram a sua maior notoriedade na segunda metade da década de 1880, aparecendo cada vez mais nos jornais e conquistando seu espaço nas ruas durante os dias de carnaval. Eles foram reconhecidos, por jornalistas e outros observadores contemporâneos, como "africanos" - "danças africanas", "instrumentos africanos" e "trajes africanos" - desfilando pelas ruas da cidade. O objetivo principal deste trabalho é tentar entender os possíveis significados por trás do ato de criar, preservar e transformar uma ação festiva que tem o passado africano como elemento fundamental para a formação de identidade para os seus membros. Essa identidade africana foi reforçada precisamente enquanto a luta pela abolição da escravatura tornou-se mais intensa e os debates sobre cidadania tornaram-se mais fortes do que nunca.

Abstract:

A study of the family Cucurbitaceae in Akwa Ibom State, Nigeria, was carried out in 15 Local Government Areas in different ecological zones across the State, where collections were made between May 2017 and June 2018. A total of eleven species in nine genera were collected: Citrullus lanatus, Citrullus mucosospermus, Cucumis sativus, Cucurbita maxima, Lagenaria siceraria, Lagenaria sphaerica, Luffa aegyptiaca, Momordica charantia, Siraitia africana, Telfairia occidentalis, and Trichosanthes cucumerina. Variation in morphology were seen in the investigated species in the stem shape that were cylindrical or angular, the compound or simple types of leaves, the indumentum of the leaf, the acute or acuminate leaf apices, the yellow or white petals, the cylindrical, spherical or irregular fruit shape, the lanceolate or irregular seed shape, and the pubescent or smooth seed. Cultivated cucurbits collected were 65% of the species investigated, while 35% occurred in the wild. A survey of the Cucurbitaceae collections in the Forest Herbarium Ibadan showed only four species recorded for Akwa Ibom State, of which only Luffa aegyptica was identified and collected in the course of this work. More cultivation should be encouraged, as this will serve as a conservation measure for cucurbits in the State.
