Objective To isolate and identify chemical constituents from Bidens bipinnata L. and screen for the an-ti-fibrosis activity. Methods The extracts were passed through HPD-100 macroporous resin columns with 100%water and 70% ethanol following by macro resin HPD-100, silica gel column chromatography, Sephadex LH-20, MCI and ODS chromatography. The structures of the components were elucidated by NMR methods. The prolifera-tion of HSC-T6 cells was evaluated by MTT. Results 13 components were isolated from the plant including 3-(hydroxyacetyl)indole (1), Kaempferol (2), 6,7,3′,4′-tetrahydroxy-aurone (3), Quercetin (4), Okanin (5), Pinoresinol (6), (3E,11E)-tetradecadiene-5,7,9-tetrayn-1,2,13-triol (7), Isookanin (8), bis (2-ethylheptyl) phythalate (9), kaempferol-3-O-α-L-rhamnoside (10), (2S/2R) isookanin-7-O-β-D-(2″,4″,6″-triacetyl)gluco-pyranoside (11/12), 2-O-β-D-glucosyltri-deca-3,11E-en-5,7,9-tetrayn-1,13-diol (13). Conclusion 13 com-ponents are isolated from Bidens bipinnata L. , among which compounds 6, 9 are isolated from this genus for the first time and compounds 2, 4 could inhibit the proliferation of HSC-T6 cells.
