摘　　要：目的:分析云南产藜蒿(Artemisia selengensis)茎和叶挥发油的化学成分。方法:采用水蒸气蒸馏法提取挥发油;通过气相色谱-质谱(GC-MS)联用技术进行成分分析。结果:藜蒿叶挥发油含41种成分,主要成分为1,8-桉树脑(17.17%)、β-崖柏烯(10.84%)、(1S)-(-)-樟脑(9.62%)、檀紫三烯(8.45%)、龙脑(8.37%)、α-蒎烯(4.24%)、β-石竹烯(1.22%)等。藜蒿茎挥发油含46种成分,主要成分为:1-(2-氨基苯)吡咯(14.51%)、檀紫三烯(8.16%)、α-蒎烯(6.62%)、β-崖柏烯(3.9%)、β-石竹烯(1.08%)等。结论:云南产藜蒿茎、叶挥发油的成分及含量有较大差异,本研究为藜蒿的综合开发利用提供了一定科学依据。Objectv ： To study the chemical constituents of essential oil of Artemisia selengensis. Methods ： Extracted the essential oil by conventional steam distillation method and analysis by GC - MS. Results： 41 compounds of essential oil from the leaves of Artemisia selengensis were identified and the principal constituents are 1, 8-cineole （17.17%）, β-thujene （10.84%）, （1S） - （-） -camphor （9.62%）, santolina triene （8.45%）, camphol （8.37%）, α - pinene （4.24%）, β- caryophyllene （ 1.22% ）, etc. 46 compounds of essential oil from the stem of Artemisia selengensis were identified and the principal constituents are 1 - （2 -ami- no benzene） pyrrole （ 14. 51% ）, santolina triene （8.16%）, α - pinene （6.62%）, β - thujene （3.9%）, β -caryophyllene （1.08%）, etc. Conclusion： There were signed differences in composition and in content of the essential oil between leaves and stems. This study can be served as a scientific basis for the further exploitation and utilization of Artemisia selengensis.
