摘要: 本文主要研究平颏海蛇干体的化学成分及其抗氧化活性。采用硅胶柱色谱、凝胶柱色谱、重结晶等方法进行分离纯化,从平颏海蛇干体中分离得到7个化合物,根据理化性质和波谱数据鉴定化合物的结构分别为:胆甾醇(1)、5,6β-Epoxysitosteryl oleate (2)、9-Octadecenoic acid (9Z)-, (2R)-2,3bis[(1-oxooctadecyl)oxy] propyl ester (3)、1-甲基海因(4)、α-棕榈酸甘油酯(5)、鲛肝醇 (6)、7α-甲氧基-β-谷甾醇 (7)。其中化合物2、3、5、6、7为首次从平颏海蛇中分离得到。采用DPPH自由基清除试验评价化合物的抗氧化活性,结果表明7个化合物几乎无抗氧化活性。

Abstract: To study the chemical constituents of the dry Lapemis curtus, and the antioxidant activity of the isolated compounds.The seven compounds were isolated and purified from the dry Lapemis curtus using different kinds of column chromatography.Their structures were determined as cholesterol (1), 5,6β-Epoxysitosteryl oleate (2), 9-Octadecenoic acid (9Z)-, (2R)-2,3-bis[(1-oxooctadecyl)oxy] propyl ester (3),1-methylhydantoin (4), α-palmityl glycerin ether (5),Chimyl alcohol (6), 7α-methoxyl-β-sitosterol (7) onthe basis of the physicochemical properties and spectral analysis.Compounds 2,3,5,6 and 7 were isolated from the dry Lapemis curtus for the first time.All compounds show weak antioxidant activity by DPPH method.
