Abstract

AIM: To study the chemical constituents of Sargentodoxa cuneata. METHODS: To isolate compounds with chromatography technology and to elucidate their structures by spectral analysis. RESULTS: Ten phenolics were isolated from Sargentodxa cuneata and their structures were determined as 1-O-(vanillic acid )-6-O-( 3", 5"-dimethoxy-galloyl)-beta-D-glycoside (I), (-)-epicatechin (II), phydroxyphenylethanol ferulate (III), chlorogenic acid (IV), methyl chlorogenate (V), apocynin (VI), vanillic acid (VII), protocatechuic acid (VIII), 3,4-dihydroxy-phenylethanol (IX), tyrosol (X). CONCLUSION: Compound I is new compound, compound III-VI and VIII-X were isolated from Sargentodoxa cuneata for the first time.
