Abstract:
Objective To elucidate the constituents from the root of Euphorbia pekinensis and to look for new products with antitumor activity.Methods The chromatography on silica gel was used and the structures were identified by IR,NMR,and MS spectral analyses and their physicochemical properties were comparied.Results Eight compounds were isolated and identified as octadecanol(Ⅰ),octadecanyl-3-methoxy-4-hydroxybenzeneacrylate(Ⅱ),?-sitosterol(Ⅲ),triacontanoic acid(Ⅳ),2,2′-dimethoxy-3,3′-dihydroxy-5,5′-oxo-6,6′-biphenylformic anhydride(Ⅴ),euphol(Ⅵ),tirucallol(Ⅶ),and euphpekinensin(Ⅷ).Conclusion The compounds Ⅰ,Ⅳ,Ⅵ,and Ⅶ are isolated from the roots of E.pekinensis for the first time.
