Abstract:
Objective To study the chemical components from aerial part of Tibetan herbal medicines Biebersteinia heterostemon. Methods The chemical constituents were isolated and purified by silica gel, Sephadex LH-20 chromatography and preparative liquid chromatography. Their structures were identified by physicochemical properties and spectral analysis. Results Thirteen compounds were isolated from B. heterostemon and their structures were identified as umbelliferone (1), 5,7,3’-trihydroxy-8,4’,5’- trimethoxyflavone (2), luteolin (3), quercetin (4), protocatechuic acid methyl ester (5), apigenin (6), alternariol (7), luteolin-7-O-β-D- glucoside (8), quercetin-3-O-β-D-glucoside (9), (+)-dehydrovomifoliol (10), β-sitosterol (11), 4’-methoxytricetin (12), and 3’,4’,5,8- tetrahydroxyflavanone-7-O-β-glucopyranoside (13). Conclusion Compounds 3, 5-7, 10, 11-13 are isolated from B. heterostemon for the first time. Compounds 5, 7, 10, 12, 13 are isolated from the genus Biebersteinia for the first time.
