Six flavonoids, including one flavan‐3‐ol epicatechin ( 1 ), one flavone glycoside apigenin 7‐ O ‐ β ‐D‐glucopyranoside ( 2 ), three flavones namely dimethylchrysin ( 3 ) , trimethylapigenin ( 4 ) and luteolin ( 5 ) and one flavonol quercetin ( 6 ) were isolated from the hexane and chloroform extracts of the leaves of Sterculia foetida Linn. collected in Binh Thuan Province by using various chromatographic methods. Their chemical structures were identified by comparing their spectroscopic data as well as physical properties with those in literature. Compounds 1‐4 were obtained for the first time in Sterculia genus.
