OBJECTIVE
To study the chemical constituents from the leaves of Sterculia foetida.


METHODS
Compounds were isolated by chromatographic techniques. Their structures were elucidated by spectroscopic methods.


RESULTS
Eight compounds were identified as 5,7,8-tetrahydroxy-4'-methoxyflavone-8-O-beta-D-glucoside (1), 5,7,8-tetrahydroxy-4'-methoxyflavone-7-O-beta-D-glucoside (2), quercetin-3-O-beta-D-glucoside (3), apigenin-6, 8-di-C-beta-D-glucoside (4), puerarin (5), 5,7,8,3'-tetrahydroxy-4'-methoxyflavone (6), 5,7,8-tetrahydroxy-3',4'-dimethoxyflavone (7), 5,7,8-tetrahydroxy-4'-methoxyflavone (8).
