摘　　要：目的:对3种不同方法提取的蓝布正挥发油的化学成分进行分析研究。方法:采取水蒸气蒸馏(SD)法、同时蒸馏萃取(SDE)法和微波萃取(MAE)法3种方法提取蓝布正挥发油,用 GC-MS 分析其化学成分。以 HP-5MS 毛细管柱为分离柱,程序升温从50℃(保持2 min)开始以4 ℃·min^(-1)。升到180℃,再以9℃·min^(-1)升到290℃,保持5 min,气化室温度250℃,载气为高纯氦气(1.0 mL·min^(-1))。结果:通过计算机检索,共鉴定出58个化合物。结论:SD 法和 SDE 法提取的挥发油成分相似,MAE 法与前2种方法提取的挥发油化学成分有差异。Objective：To analyze the chemical constituents of volatile oils from Herba Gei with three kinds of extraction methods. Methods ： The volatile oils from Herba Gei were extracted by stream distillation （ SD）, simultaneous distillation extraction （SDE） and microwave extraction （MAE） method, and analyzed their spectrometry （ GC - MS） by capillary columns gas chromatography with HP- 5MS phenyl methyl siloxane capillary columns. The column temperature was in rate of 4 ℃ min ^-1 from 50 ℃ （ hold 2 min） to 180 ℃ , then in rate of 9 ℃· min^ -1 from 180 ℃ to 290℃ （kept 5 rain）. The carrying gas was helium （ 1.0 mL· min^-1 ）. Results：58 compounds were identified. Conclusion：The compounds from the volatile oils extracted with SD and SDE are resentble. The oil with MAE is different from the two formers.
