Hibiscus sabdariffa: Genetic variability, seasonality and their impact on nutritional and antioxidant properties

Abstract
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.
