Abstract:
Objective To study the chemical constitients of Polygonum cuspidatum.Methods The compounds were isolated through column chromatography and their structures were elucidated through physicochemical and spectral analyses.Results Seven compounds were obtained from the diethyl ether fraction of ethanol extract and identified as physcion(Ⅰ),emodin(Ⅱ),ambrettolide(Ⅲ),?-sitosterol(Ⅳ),oleanolic acid(Ⅴ),coumarin(Ⅵ),and 2-ethoxy-8-acetyl-1,4-naphthoquinone(Ⅶ).Conclusion Compound Ⅶ is a new compound named as cuspidatumin A,and compound Ⅲ is obtained from P.cuspidatum for the first time.
