Abstract:
Objective To investigate chemical constituents in the leaves of Euphorbia soongarica(Xinjiang origin).Methods The leaves were extracted with 95% EtOH and partitioned with petroleum ether,CHCl3,and n-BuOH,respectively.Compounds were isolated by using repeated silical gel column chromatography and Sephadex LH-20 column chromatography.Results Eight compounds were identified on the basis of physiochemical properties and spectral data as chrysoeriol(Ⅰ),phthalic acid,bis-(2,5-dimethylhexyl) ester(Ⅱ),fraxetin(Ⅲ),3-(4-O-?-D-glucopyranosyloxy-3,5-dimethoxy)-phenyl-2E-propenol(Ⅳ),fraxin(Ⅴ),3-methylellagic acid-3′-O-?-D-xylopyranoside(Ⅵ),3,3′-dimethylellagic acid-4-O-sulphate(Ⅶ),and(+)-isolariciresinol-9-O-?-D-xylopyranoside(Ⅷ).Conclusion Compound Ⅶ is a new natural product,the other seven compounds are obtained from this plant for the first time.
