摘　　要：目的:研究佛甲草的化学成分。方法:采用硅胶柱色谱、薄层色谱、结晶等方法对佛甲草中化学成分进行分离、纯化,根据化合物的理化性质和波谱数据分析和鉴定其结构。结果:从佛甲草的乙醇提取物石油醚部位中共分离得到6个甾醇类化合物和2个三萜类化合物,分别鉴定为豆甾-5-烯-3β-醇-7-酮(1)、豆甾-5-烯-3β,7α-二醇(2)、胡萝卜苷(3)、胡萝卜苷棕榈酸酯(4)、β-谷甾醇(5)、豆甾-7-烯-3β-醇(6)、δ-香树脂醇(7)、δ-香树脂酮(8)。结论:化合物3、4、7为首次从佛甲草中分离得到,其中化合物4为首次从佛甲草属植物中分离得到。该研究为佛甲草的质量评价奠定了一定基础。OBJECTIVE：To study the chemical constituents of Sedum lineare. METHODS：Silica gel column chromatography,TLC and crystallization were adopted to isolate the chemical constituents of S. lineare. And chemical structures were analyzed and identified based on physicochemical properties and spectral data of compounds. RESULTS：A total of 6 sterols and 2 triterpenoids were isolated from petroleum ether fraction of S. lineare,which were identified as stigmaster-5-ene-3β-ol-7-one（1）,stigmaster-5-ene-3β,7α-diol（2）,daucosterol（3）,daucosterol palmitate（4）,β-sitosterol（5）,stigmaster-7-ene-3β-ol（6）,δ-amyrin（7）,andδ-amyrone（8）respectively. CONCLUSIONS：Compounds 3,4 and 7 are isolated from S. lineare for the first time,and compound4 is isolated from genus S.lineare for the first time. The study has laid certain foundation for the quality evaluation of S. lineare.
