摘　　要：[目的]研究印度獐牙菜石油醚部位化学成分。[方法]分别用石油醚、乙酸乙酯和正丁醇萃取印度獐芽菜乙醇浸膏,所得产物用硅胶柱、Sephadex LH-20柱洗脱后进行结构鉴定。[结果]从印度獐芽菜全草乙醇提取物的石油醚部位分离得到2个化合物,经鉴定分别为β-谷甾醇(Ⅰ)和1,8-二羟基-3,5-二甲氧基山酮(Ⅱ)。[结论]2种化合物β-谷甾醇与1,8-二羟基-3,5二甲氧基山酮均为首次从印度獐芽菜乙醇提取物的石油醚部位分离得到。[ Objective ] The research aimed to study the chemical constituents from Swertia chirata extracted with petrolelum ether. [ Method ] S. chirata ethanol-extracts was extracted with petrolelum ether, ethyl acetate and butanol, respectively. And the products were eluted with silica gel column and Sephadex LH-20 column before structure identifiation. [ Result] Two compounds were isolated from the petrolelum ether fraction of S. chirata, and they were identified as β-sitosterol and swerchirin by spectral method. [ Conclusion ] These two compounds were got firstly from the petrolelum ether fraction of S. chirata.
