摘要
采用冷渗漉提取的方法提取马兰的化学成分。经硅胶柱色谱和Sephadex LH-20进行分离纯化,通过理化方法和波谱数据分析进行结构鉴定。从80%乙醇冷渗漉提取物的水不溶物中分离并鉴定了12个化合物,分别为正十六烷酸(1)、6-羟基-桉烷-4(14)-烯(2)、β-谷甾醇(3)、α-菠菜甾醇(4)、香草醛(5)、β-20(21),24-二烯-达玛烷-3-酮(6)、豆甾醇(7)、木栓酮(8)、羽扇豆酮(9)、α-香树脂醇(10)、表木栓醇(11)、神经酰胺(12)。化合物2、6、9、12均为首次从该种植物中分得。
The chemical constituents were extracted from Kalimeris indica by cold percolation extraction.Compounds were isolated and purified with silica gel and Sephadex LH-20 column chromatography,the structures were determined on the basis of physicochemical evidence and ectroscopic analysis.Twelve compounds were separated and purified from water insoluble parts of 80% alcohol extracts of K.indica.They were identified as n-Hexadecanioc acid(1)、6-Hydroxy-eudesm-4(14)-ene(2)、β-Sitosterol(3)、α-Spinasterol(4)、Vanillin(5)、3-Oxo-dammara-20(21),24-dene(6)、Stigmasterol(7)、Friedelin(8)、Lupeone(9)、α-Amyrin(10)、Friedel-3-ol(11)、(2S,3S,4R,8E)-2-[(2R′)-2′-Hydroxyteracosenoilamino]-8-octadecene-1,3,4-triol(12).Compounds 2、6、9、12 were isolated from this plant for the first time.
