Abstract:
Objective To investigate the chemical constituents of Polygala fallax.Methods The chemical constituents were isolated and purified via silica gel and Sephadex LH-20 column chromatography as well as recrystallization.Their structures were determined on the basis of spectral analysis and physicochemical properties.Results Six compounds were isolated and identified as 3-O?-D-glucopyranosyl senegenic acid(Ⅰ),tenuifolin(Ⅱ),presenegenin(Ⅲ),1,7-dimethoxy-2,3-methylenedioxy xanthone(Ⅳ),sinapinic acid(Ⅴ),ferulic acid(Ⅵ).Conclusion Compounds Ⅲ—Ⅵ are isolated from P.fallax for the first time.Compound Ⅰ is a new triterpenoid saponin,named fallaxsaponin A.
