摘　　要：目的:用GC-MS分析小飞蓬挥发油的化学成分。方法:采用水蒸气蒸馏法提取小飞蓬挥发油,利用GC-MS对所提取的挥发油成分进行分离鉴定,并用色谱峰面积归一化法计算各成分的相对百分含量。结果:鉴定出小飞蓬挥发油成分中26个化合物,占所提取挥发油总量的98.25%。主要成分为:柠檬烯(58.30%)、2,6-二甲基-6-(4-甲基-3-戊烯基)二环[3.1.1]-2-庚烯(8.7%)、β-蒎烯(6.28%)、2-甲基-6-(4-甲基苯基)-2-庚烯(5.13%)、棕榈酸(5.07%)、月桂烯(4.52%)、1,3,5-三亚甲基-环庚烷(2.05%)。结论:小飞蓬挥发油主要成分为柠檬烯。Objective：To analyze the constituents of volatile oil from Erigeron canadensis by GC-MS.Method： The volatile oil was extracted by steam distillation,and then separated by capillary gas chromatography.The constituents of volatile oil were identified and their amount was determined by normalization method.Result： Twenty-six components were identified from E.canadensis and their amount accounted 98.25% of total volatile oil.The main components were limonene（58.30%）,2,6-dimethyl-6-（4-methyl-3-pentenyl） bicyclo -2-heptene（8.7%）,β-pinene（6.28%）,2-methyl-6-（4-methyl-phenyl）-2-heptene（5.13%）,palmitic acid（5.07%）,myrcene（4.52%）,1,3,5-trimethylene-cycloheptane（2.05%）.Conclusion： The main component of volatile oil from E.canadensis is limonene.
