Abstract:
The ethyl acetate fraction of 80% ethanol extract from Bidens parviflora Willd．was isolated and purified by silica, polyamide, Sephadex LH-20 and HPLC. A total of eleven compounds were isolated and identified by physicochemical properties and spectral data as (2S)-11E-tetradecene-3,5,7,9-tetrayne-1,2,13-triol (1), pyridine-4-formyl-O-β-D-glucopyranoside (2), maritimein (3), trichocarpine (4), okanin-4-methyl ether-3′-O-β-D-glucopyranoside (5), okanin-4-methyl ether-4′-O-β-D-(6″-acetyl)-glucopyranoside (6), (Z)-6-O-(4″-acetyl-6″-O-p-coumaroyl-β-D-glucopyranosyl)-6,7,3′,4′-tetrahydroxyaurone (7), quercetin-3-O-α-L-arabinoside (8), hyperoside (9), (3S)-(6E,12E)-tetradecadiene-8,10-diyne-1,14-diol-3-O-β-D-glucopyranoside (10), bipinnata polyacetyloside B (11). Compounds 1 and 2 are new compounds, compounds 4 and 8 were isolated from the genus Bidens for the first time, compounds 5-7, 10 and 11 were isolated from this plant for the first time.
