Phenolics from traditional Chinese medicine Sargentodoxa cuneata

AimTo study the chemical constituents of Sargentodoxa cuneata. MethodsTo 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)-β-D-glycoside (I), (-)-epicatechin (II), P-hydroxyphenylethanol ferulate (III), chlorogenic acid (IV), methyl chlorogenate (V), apocynin (VI), vanillic acid (VII), protocatechuic acid (VIII), 3,4-dihydroxy-phenylethanol (IX), tyrosol (X). ConclusionCompound I is new compound, compound III—VI and VIII—X were isolated from Sargentodoxa cuneata for the first time.
