ABSTRACT
AIM To study the chemical constituents from the Polygonum amplexicaule var.sinense.METHODS The n-butanol fraction of ethanol extract from P.amplexicaule var.sinense was isolated and purified by TLC,normal-phase silica,macroporous resin column,sephadex column,preparative TLC and semi-preparative HPLC column,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Ten compounds were identified as 2-(aminomethyl)-4-methoxy-phenol (1),p-methyl-hydroxybenzoate (2),p-methyl-hydroxyphenylacetate (3),2-[2-(methylamino) phenyl]-4-thiazolecarboxylic acid,methyl ester (4),p-methylphenylethanol (5),bergenin (6),arbutin (7),rhododendron-2-O-β-D-glucopyranoside (8),n-butyl gallate (9) and β-sitosterol (10).CONCLUSION Compounds 1-8 are isolated from this plant for the first time.
