Abstract: The chemical constituents of Clematis tangutica was investigated by the methods of Si-gel,Sephadex LH-20,ODS and MPLC,and the structures of compounds were identified by means of physicochemical properties and spectral analysis.Eleven compounds were isolated from the ethyl acetate fraction of Clematis tangutica, and identified as luteolin(1),clemaphenol A(2),alpha-linolenic acid(3),daucosterol(4),daucosterolaglycone(5 ),hederagenin-3-O-α-L-rhamnopyranosyl(1→4)-β-D-glucopyranosyl (6), hederagenin-3-O-α-L-arabinopyranosyl(1→3)-α-L-rhamnopyranosyl(1→4)-β-D-glucopyranosyl(7), Acanjaposide G(8),hederagenin(9),apigenin(10),echitin(11).All of these compounds were obtained from the plant for the first time.
