“…Despite the known importance of bioactive compouds content of kola, efforts to breed varieties with enhanced levels of these compounds is lacking. Breeding of fruits with enhanced amounts of nutritional and phenolic traits is deemed very necessary [28][29][30][31] to promote good health among consumers. Farmers and other stakeholders along the kola value chain in Ghana use kola for medicinal purposes and indicated their preference for kola varieties with high nutritional and medicinal compounds content [32].…”

Cola nitida known as Kola serves as flavouring ingredient in the food industry and is also of great importance during traditional rites in Africa. Despite the well-known pharmaceutical values of the species, efforts to develop improved varieties with enhanced nutraceutical quality is limited due to unavailability of information on variation of genotypes in bioactive compounds in the nuts. The objectives of this research were to evaluate 25 genotypes of kola for bioactive contents, determine relationship between nutritional and phenolic traits and to identify kola genotypes with good nutraceutical quality for use in developing improved varieties. The kola genotypes were established in the field using a randomized complete block design with three replicates. Nuts harvested from the blocks, were bulked and used to quantify soluble and insoluble sugars, total protein, moisture, ash, fats, pH, polyphenols, tannins and flavonoids using completely randomized design with three replicates in the laboratory. Data were analysed by combining Analysis of Variance, Kruskal-Wallis test, correlation test and multivariate analysis. Significant variations (P < 0.05) were observed among the kola genotypes for the bioactive traits evaluated. Phenolic traits were more heritable than nutritional traits. Although not significant (P > 0.05), correlation between nutritional and phenolic traits was negative, whereas correlations among nutritional traits were weak. On the contrary, significant and positive correlations (P < 0.05) were observed among phenolic traits. The hierarchical clustering analysis based on the traits evaluated grouped the 25 genotypes of kola evaluated into four clusters. Genotypes A12, JB4, JB19, JB36, P2-1b, and P2-1c were identified as potential parental lines for phenolic traits selection in kola whereas genotypes A10, Club, Atta1 and JB10 can be considered for soluble and insoluble sugar-rich variety development. These findings represent an important step towards improving nutritional and nutraceutical quality of kola nuts.

“…The utilization of medicinal plants and plant-derived products for therapeutic purpose is rapidly increasing and gaining attention globally because they exhibit little or no safety concern and their biofriendliness compared to synthetic medications. Cucurbita pepo (Pumpkin), an economically and nutritionally important fruitbearing vegetable belonging to the family Cucurbitaceae, is a reservoir of variety of nutrients and bioactive compounds such as unsaturated fatty acids, micro and macro minerals, α and γ tocopherols, β-carotene, proteins (albumin and globulins), vitamins and phytosterols [10][11][12][13][14].…”

Introduction: Paraquat is a bipyridil herbicide commonly used in modern agriculture for weed and pest control. Paraquat poisoning usually occurs through direct ingestion for suicidal intent, causing mortality as a consequence to oxidative damage, inflammation and multi-organ failure. Objectives: In this study, we investigated the ameliorative potential of Cucurbita pepo fruit on paraqaut-induced oxidative damage, inflammation, hyperlipidemia, hepatotoxicity and nephrotoxicity in rats. Methods: Rats were orally administered paraquat (2 mg/kg b.w) with or without the fruit extract (500 mg/kg b.w) or resveratrol (3.57 mg/kg b.w) co-administration for 2 weeks. Results: We found C. pepo fruit extract significantly restored paraquat-induced oxidative damage, acute inflammation and hyperlipidemia. Reduced glutathione (GSH) concentration was significantly abridged in paraquat treated group, while the concentration of GSH increases substantially across groups administered fruit extract and resveratrol. Furthermore, paraquat induced concomitant reduction in the activity of glutathione peroxidase (GPx) and superoxide dismutase (SOD), which was restored by the fruit extract and resveratrol. However, nitric oxide level demonstrated a substantial elevation in paraquat-treated group, but restored by both the fruit extract and resveratrol. Moreover, pumpkin fruit extract and resveratrol supplementation suppressed overproduction of total cholesterol, triglycerides, low density lipoproteins, high density lipoproteins and thus, alleviated paraquat-induced hyperlipidemia. In addition, administration of C. pepo fruit extract and resveratrol ameliorated the hepatotoxic and nephrotoxic effect caused by paraquat. Conclusion: We conclude that C. pepo fruit extract and resveratrol administration ameliorated oxidative damage, acute inflammation, hyperlipidemia, hepatotoxicity and nephrotoxicity caused by paraquat ingestion.

“…The cultivated populations of E. fulgens in greenhouse showed a morphometric variation in vegetative structures, similar to the wild-growing groups, which suggests that these characteristics are highly stable in this species. In most studies of ornamental plants, phenotypic differences in structures with aesthetic or commercial value are evaluated; for instance, stem length, firmness, and flower number, size, colour, and odor in Peruvian lily [15]; branch number and length, flowering duration, height, disc and ligulate flowers, and central head diameter in sunflower [14]; and growth habit, ramification, foliar blade, and fruit shape, size, and colour in ornamental gourds to obtain ideal genotypes for cut flower, bouquets, arrangements, or pots [16]. Cultivation of E. fulgens in greenhouse demonstrated that it adapts and develops well under controlled conditions.…”

Morphological variation is useful in conservation and genetic improvement programs. Euphorbia fulgens, a range-restricted local endemic species of Mexico, is used locally during the altars in the festivities of different saints and is also cultivated as an ornamental plant mainly in Europe. Thus, in the present study, morphological variation was evaluated in wild populations and cultivated populations. Characterization of 90 individuals from three wild populations (the only ones recorded to date) was done by measuring 30 morphological traits both vegetative and reproductive. Thereafter, seeds were collected, and established under greenhouse conditions, and 39 morphometric variables were evaluated in adult plants. An analysis of variance (ANOVA) was done for wild and cultivated groups independently, and when significant differences were found, Tukey’s comparison of means was applied (p < 0.05). To identify the traits responsible for the differences between wild and cultivated groups, a linear discriminant analysis (LDA) was conducted. Morphological variation was found among wild populations, and this variation decreased in cultivated populations, mainly in reproductive structures. The LDA separated the wild populations from the cultivated groups, according to inflorescence length, petiole length/blade length ratio, and leaf roundness. The variables that determined the separation of individuals between wild and cultivated populations were cyme number, foliar Feret diameter, and inflorescence length, variables that can be important for breeding strategies and artificial selection.
