ABSTRACT
To investigate the chemical constituents of the whole plants of Bidens bipinnata, the separation and purification of constituents were performed by chromatography on macroporous resin, silica gel, MCI and Sephadex LH-20. Their structures were elucidated by spectroscopic data as quercetin (1), quercetin-3-0-alpha-L-rhamnoside (2), keampferol-3-O-beta-D-glucopyranoside (3), keampferol-3-O-alpha-L-rhamnoside (4), 3', 5-dyhydroxy-3, 6, 4'-trimethoxyl -7-O-beta-D-glucopyranoside flavonoid (5), 7, 8, 3', 4'-tetraflavanone(6), (2S)- and (2R)-isookanin-7-O-beta-D- glucopyranoside (7a/7b), (2S)- and (2R)-3'-methoxy-isookanin-8-O-beta-D-glucopyranoside (8a/8b), 6, 7, 3', 4'-tetrahydroxyaurone(9), maritimetin (10), esculetin (11), 3-O-caffeoyl-2-methyl-d-erythrono-1, 4-lactone (12), (7S, 8R) balanophonin-4-O-beta-D-glucopyranoside (13), eugenyl-O-beta-apiofuranosyl-( 1"-6') -O-beta-glucopyranoside (14), and (+)-syringaresinol-4'-O-beta-D-glucopyranoside (15). Compounds 8, 13, 14, and 15 were isolated from this genus for the first time. Compounds 1 and 6 were potent inhibitors against HSC-T6 cells in vitro and compounds 1, 2, 6, and 7 were capable of decreasing the inflammatory cytokine production of macrophage cells in vitro.
