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.
