Abstract :
Anthocyanin content of Hibiscus sabdariffa calyces was determined to compare two cultivars from Senegal called Koor and Vimto. Results showed a significant difference in terms of total anthocyanin content (TA) and relative abundance (RA) of anthocyanin species. Values of TA for Vimto were 3-fold higher than Koor’s. Two minor anthocyanins, delphinidine-3-glucoside and cyanidine-3-glucoside, not frequently mentioned in literature, were detected in both cultivars. Cyanidin-3-glucoside in particular was present only in Koor calyces. The influence of agronomic conditions on TA and RA was highlighted.
