[Flavones from flowers of Sesamum indicum].
OBJECTIVE
To investigate the chemical constituents from flowers of Sesamum indicum.


METHODS
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.


RESULTS
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).


CONCLUSIONS
All of the compounds were isolated from this plant for the first time.
