摘　　要：目的:研究龙胜香茶菜化学成分。方法:采用硅胶柱层析进行分离纯化化合物,依据理化性质和现代波谱技术进行结构鉴定。结果:从龙胜香茶菜叶乙醇提取物的石油醚部位分离出4个单体化合物,分别鉴定为龙胜香茶菜素E(1)、鲁山冬凌草丙素(2)、β-谷甾醇(3)和十六烷酸(4)。结论:化合物4为首次从该植物中获得;石油醚部位中活性成分β-谷甾醇含量近5%。Objective： To explore the chemical constituents of Isodon lungshengensis. Methods： Compounds were separated and purified by silica gel column chromatography and their structures were elucidated on the basis of spectral data and chemical evidences. Results： Four compounds were obtained from petroleum ether fraction of the extract from leaves of 1. lungshengensis and identified as lungshengenin E （1）, lushanrubescensin C （20）, β-sitosterol （3）, and palmific acid （4）. Conclusion： Compound 4 is isolated from this plant for the first time; there is very high amount of β-sitosterol in the petroleum ether fraction.
