ABSTRACT
Objective To study the chemical constituents from ethyl acetate extracts of the strips of Semiliquidambar cathayensis.Methods The strips of S.cathayensis were extracted by 80%ethanol and the extracts were evaporated.Fourteen compounds in ethyl acetate extracts were isolated and purified by various chromatographic techniques,such as silica gel,Sephadex LH-20 column and pre-HPLC,etc.Their structures were identified on the basis of physicochemical properties and spectroscopic analysis.Antioxidant activity test was used to evaluate total extraction,each extraction part and the isolates.Results Fourteen compounds were isolated from the strips of S.cathayensis and identified by NMR as tetradecanoic acid(1),stearic acid(2),sesamin(3),9-octadecenoic acid(4),linoleic acid(5),dibutylphthalate(6),stigmasterol(7),β-sitosterol(8),lupeol(9),oleanolic acid(10),lup-20(29)-ene-3-[3-keto-hexadecanoate](11),peujaponisin(12),C-veratroylglycol(13),and 2,3-dihydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone(14).Conclusion Compounds 1,3,4,5,6,7,9,11,12,13 and 14 were isolated from this plant for the first time.The EA part,compounds 13(C-veratroylglycol)and 14(2,3-dihydroxy-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone)showed significant antioxidative effects.
