Objective:
To study the chemical constituents from the leaves of Sterculia foetida.
Method:
Compounds were isolated by chromatographic techniques. Their structures were elucidated by spectroscopic methods.
Result:
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).
Conclusion:
Compounds 1, 2 and 4-8 were isolated from this plant for the first time.
