摘　　要：目的:对甘肃产百里香挥发油成分进行分析比较研究。方法:水蒸气蒸馏法提取百里香挥发油,用GC/MS法对不同样品精油成分进行分析鉴定,并利用柱色谱法对挥发油中部分化合物分离纯化,辅助鉴定精油化学成分。结果:从3种精油中共鉴定出89种化合物,其中化合物相对含量大于0.5%的共有成分有10种。达宗湖产精油主要成分为香叶醇、百里香酚和长叶烯等;扎油沟产精油以芳樟醇和百里香酚等为主;天水产精油主要含有侧柏烯、桉叶醇、百里香酚和雪松醇等。结论:甘肃产百里香挥发油的主要化学成分为单萜类化合物;同种植物由于生长环境的差异,使其精油成分及相对含量产生影响。Objective：To study differences between the essential oil of Thymus mongolicus from Gansu by GC /MS.Method：The essential oils were extracted with steam distillation method.The relative amount of each component was calculated in area normalization.The compounds in oils were isolated by column chromatography to identify the chemical constituents of essential oils as assistant method.Result：Eighty-nine compounds were identified in the three essential oils.The major constituents of oils from Dazonghu region were geraniol,thymol and longifolene,and from Zhayougou were linalool and thymol,ect.The major constituents of oils from Tianshui were sabinene,eucalyptol,thymol,cedrol,ect.Conclusion：The main chemical component of essential oil of T.mongolicus in Gansu were monoterpenes.The differences in growing environment were different with relative content of essential oil composition.
