To compare the phytochemical and biological profiles, infusion and decoction extracts of dried Hibiscus sabdariffa calyces were prepared. Infusion extract had the highest phenolic content (292.42 ± 0.62 mg GAE/g extract) and antioxidant activity (TEAC = 3.09 ± 0.28). It also potently inhibited the activities of α-amylase (58.57 ± 1.4%), α-glucosidase (66.92 ± 2.5%) and 5-lipoxygenase (58.97 ± 1.17 μg/ml). All extracts showed weak cytotoxicity as tested on Vere monkey kidney cells.
