Abstract:
:Two new and one known compounds were isolated from the methanol extract of Sesamum indicum leaves. By means of spectroscopic methods, their structures were elucidated and identified to be 3-epibartogenic acid (1), kaempferol 3-O-[2-O-(trans-p-coumaroyl)-3-O-α-L-rhamnopyranosyl]-β-D-glucopyranoside (2) and epigallocatechin (3). Compound 1 and 3 strongly inhibited α-amylase with the IC50 values of 146.7 and 303.9 μM, respectively, in comparison with acarbose (IC50 124.0 μM).
