This study consisted of the physicochemical, phytochemical and antioxidant characterisation of two varieties of Hibiscus sabdariffa, to evaluate the influence of genetic and environmental factors on these parameters leading to an objective and rigorous classification of our extracts. To this end, calyxes and seeds of the red and white phenotypes were collected in Bobo-Dioulasso, Dano and Nouna respectively in December 2019 and 2020. Principal component analysis showed that physico-chemical and biochemical parameters could potentially be used to discriminate varieties. The calyxes of the sabdariffa variety showed the best physicochemical profile (total phenolics, flavonoids, ascorbic acid), pigments (anthocyanins, chlorophyll) and antioxidant activity (free radical scavenging and SOD activity) while the seeds showed the best carbohydrate, lipid and peroxidation inhibition content. In view of these results, the red phenotype has an interesting nutritional and therapeutic potential. It could therefore be interesting candidate in the pharmaceutical and food industries.

A study on the potential for agronomic valorisation of Jatropha curcas co-products in rainfed agriculture was conducted in Burkina Faso to determine the impacts of compost-based by-products of Jatropha on the nutritional quality of the sorghum seeds produced. The effect of 13 composts was evaluated and compared to a control. Sorghum seed parameters determined were total phenolics, total flavonoids, starch, total sugars, phorbol esters and antioxidant activities measured with DPPH and FRAP protocols. The results have showed a statistically significant difference between the treatments for all parameters. Correlations between the different parameters mean a simultaneous improving of biochemical parameters of sorghum. The ferric reduction ability power was significantly and positively correlated to total phenolics (r = 0.792) and flavonoids (r = 0.602) content. The analysis of the main components has enabled the various treatments to be divided into 4 groups. Flavonoid content and FRAP activity are closely related to the treatment BM+CP. The treatments for the control group have improved total polyphenol content and DDPH activity. The others groups have improved starch and carbohydrate content. The phorbol ester dosage revealed no contamination of sorghum seeds. These results suggest that Jatropha by-products compost can be used as an alternative or complement to chemical fertilizers for soil fertility improvement.

“…Other studies surveying protein in legumes, particularly cowpea, have emphasized the influence of soil fertility, including nitrogen (N) and phosphorus (P), in the expression of protein content in cowpea [ 37 , 38 ]. Soil N and soil pH are factors that affect the symbiotic relationship between legumes and N-fixing bacteria, which in turn contribute to soil fertility [ 20 ].…”

Cowpea (Vigna unguiculata L.), a traditional legume food crop indigenous to Africa, has potential as both a vegetable and grain crop in contributing to dietary diversity to support health and address malnutrition, especially for those relying heavily on wheat, maize, and rice. The expression of nutritional traits (protein content and concentrations of iron (Fe), zinc (Zn), and manganese (Mn)) in cowpea leaves was evaluated over diverse agro-ecologies of South Africa and typical agronomic practices of smallholder farmers. The genotypes evaluated displayed genetic variation for all four traits. The mean values of Fe, Zn, Mn and protein content varied from 33.11 to 69.03 mg.100.g−1; 4.00 to 4.70 mg.100.g−1; and 14.40 to 19.63 mg.100.g−1 and 27.98 to 31.98%, respectively. The correlation analysis revealed significant degree of positive association between protein and Zn (r = 0.20), while negative associations were observed between Mn and protein (−0.46) and between Mn and Fe (r = −0.27). Furthermore, the expression of these important nutrient traits was influenced by the climatic conditions represented by six environments (location by year combinations) as is typical of ‘quality’ traits. Additionally, genotype-by-environment interaction effects were detected, suggesting that local soil properties and soil health may play a role in nutritional content in plants, perhaps particularly for legume crops that rely on symbiotic relationships with soil bacterial populations to fix nitrogen, which is crucial to protein formation. Further studies are needed to understand how to coordinate and align agronomic and soil management practices in vegetable cowpea production, especially those workable for the smallholder farmer, to realize the full genetic potential and nutritional value of improved vegetable cowpea varieties.
