摘　　要：目的首次对甘肃醉鱼草低极性成分进行了研究。方法采用乙醇提取,再经石油醚萃取,硅胶柱层析分离,得黄色油状物质,用GC毛细管柱进行分析,采用峰面积归一化法测定其相对含量,运用GC-MS联用技术检测并核对质谱标准图谱。结果从分离出的317种组分中鉴定出66种化合物。结论其主要成分是14-异丙基-8,11,13-罗汉松三烯-13-醇(7.68%),20-羽扇烯-3β-醇乙酸酯(4.57%)等多种类型的化合物。Objective To analyze the low polarity components from Buddleja purdomii W.W. Smith. Methods The components were isolated and identified by GC-MS. Results 317 components were isolated, and out of them 66 compounds were identified. Conclusion The main compounds of low polarity components are podocarpa-8, 11, 13-trien-13-ol, 14-isopropy1（7.68%） and lup-20 （29）-en-β-lactate（4.57%）.
