Two flavonoid glycosides and a phenylpropanoid glucose ester from the leaves of Sterculia foetida.
Two new flavonoid glycosides, hypolaetin 4'-methyl ether 8-O-beta-d-glucuronide 2''-sulfate (1) and hypolaetin 4'-methyl ether 3'-O-beta-d-glucoside (2), and a new phenylpropanoid glucose ester, 1,6-diferuloyl glucose (3), were isolated from the leaves of Sterculia foetida L. Their structures were elucidated by spectroscopic analysis and chemical evidence.
