Objective To study the chemical constituents from the herbs of Biebersteinia heterostemon. Methods The compounds were separated and purified by chromatographic methods. The structures were identified by spectroscopic analyses. Results Ten flavonoids were isolated from the butanol fraction of 95% ethanol extract in B. heterostemon and identified as diomsmin (1), apigenin-7-O-rutinoside (2), chrysoeriol-7-O-sophoroside (3), luteolin-7-rutinoside (4), quercetin-3-O-β-D-glucopyranosyl (1→2)-β-D-glucopyranoside (5), apigenin-7-O-sophoroside (6), quercetin 3-O-β-glucopyranoside (7), 6-hydroxyluteolin (8), luteoloside (9), and hypolaetin-7-O-β-D-glucopyranoside (10). Conclusion Compounds 1, 3, 5-8, and 10 are firstly isolated from B. heterostemon.
