Alpha-amylase inhibitors from roselle (Hibiscus sabdariffa Linn.) tea.

C Hansawasdi1, J Kawabata, T Kasai.   

Abstract

A roselle (Hibiscus sabdariffa Linn.) tea extract was found to have high inhibitory activity against porcine pancreatic alpha-amylase. Hibiscus acid and its 6-methyl ester were respectively isolated as active principles from the 50% methanol and acetone extracts of roselle tea. The activity of each isolate was compared to that of structurally related citric acid, a previously known inhibitor of fungal alpha-amylase.
