The chemical constituents of the stems ofAncistrocladus tectorius were isolated by silica gel and Sephadex LH-20 column chromatography,and the structures were elucidated on the basis of spectral analysis.The results showed that five known dihydroflavoids(-)-epicatechin-3-gallate(1),3,3′,5,5′,7-pentahydroxyflavan(2),(-)-catechin(3),(-)-Epicatechin(4),(-)-epigallocatechin(5)and one known phenolic compound(3,5-dimethoxy-4-hydroxyphenol)-1-O-β-D-(6-O-galloyl)glucose(6)were obtained.Compounds 1,2,4-6 were reported for the first time from this species.
