Abstract

OBJECTIVE: To investigate the chemical constituents from flowers of Sesamum indicum. METHOD: Column chromatography with silica gel, C18 and Sephadex LH -20 as packing materials was used to separate the chemical constituents, and the structures were determined by chemical and spectroscopic methods. RESULT: Six flavones were isolated and elucidated as apigenin (1), ladanetin (2), ladanetin-6-O-beta-D-glucoside (3), apigenin-7-O-glucuronic acid (4), pedalitin (5), and pedalitin-6-O-glucoside (6). CONCLUSION: All of the compounds were isolated from this plant for the first time.
