“…Indeed, seeds from both phenotypes showed the best carbohydrate and lipid contents while no significant difference was observed for protein composition. Similar proportions were obtained for carbohydrate content (101.1 ± 11.3 g.kg -1 ) and protein content (92.5 ± 4.3 g.kg-1) in red calyxes respectively [ 24 ]. lipids content of the samples was higher than those obtained elesewhere [ 24 ].…”

This difference could be explained by the climatic parameters including solar temperature.…”

“…The chromaticity index C*, which measures colour saturation was similar in the different samples (CA, GA and GA), except for the calyxes of the sabdariffa variety. The red coloration of the calyxes of the sabdariffa phenotype shows the presence of bioactive compounds including the flavyliun cation which turns red in acidic medium and the saturation may be related to the anthocyanin concentration [ 24 ].…”

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.
