Abstract:
Objective: To study the chemical constituents of Bidens parviflora. Methods: The ethyl acetate fraction of 80% ethanol extract from B. parviflora was isolated and purified by silica, polyamide, Sephadex LH-20, and HPLC, then the structures of obtained compounds were identified by physicochemical properties and spectral data. Results: Ten compounds were isolated and identified as Z-6-O-(4″-O-acetyl-6″-O-p-coumaroyl-β-D-glucopyranosyl)-6,7,3’,4’-tetrahydroxyaurone (1), okanin-4’-O-β-D-(6″-O- acetyl)-glucoside (2), Z-6-O-(4″,6″-diacetyl-β-D-)-7,3’,4’-tetrahydroxy aurone (3), 6,7,3’,4’-tetrahydroxy aurone (4), isookanin (5), syringic acid-4-O-α-L-rhamnopyranoside (6), okanin-4’-O-β-D-(6″-trans-p-coumaroyl)-glucoside (7), okanin-4’-O-β-D-(4″-acetyl- 6″-trans-p-coumaroyl)-glucoside (8), quercetin-3,4’-dimethyl ether-7-O-rutinoside (9), and cordifolioidyne B (10). Conclusion: Compound 1 is a new compound named as bidenoside I, compounds 6 and 10 are isolated from the genus Bidens for the first time, other compounds are isolated from this plant for the first time.
