摘　　要：目的分析新疆芜菁子中挥发油的化学成分。方法采用水蒸气蒸馏法提取芜菁子中的挥发油,用GC-MS分析其化学成分。结果共分离出25个峰,鉴定出了23种成分,占挥发油总成分的98%以上。主要组分为异硫氰酸-3-丁烯酯(22.98%)、3-甲基-3-丁烯腈(21.29%)、5-甲硫基戊腈(10.07%)、2,3-二甲基-2-丁烯二酸(9.82%)、异硫氰酸丁酯(9.39%)、异硫氰酸烯丙酯(8.19%)。结论所提取的挥发油中含有异硫氰酸酯、羧酸、羧酸酯、腈类、少量醛和萜类等化合物。OBJECTIVE To analyze the chemical components of the essential oil from the seeds of Brassiea rapa L. METHODS The essential oil of Brassica rapa L. seeds was extracted by steam distillation method. The chemical components of the essential oil were analyzed by GC - MS. RESULTS 25 peaks were separated totally. 23 components were identified. The main components were isothiocyanic acid, 3 - butenyl ester （ 22. 98% ） , 3 - methyl - 3 - butenenitrile （ 21. 29% ） , 5 - methyhhio - pentanenitrile （ 10. 07% ） ,2,3 - dimethylfumaric acid（ 9.82% ） , butyl isothiocyanate（ 9.39% ） and allyl isothiocyanate （ 8.19% ）. CONCLUSION There are isothiocyanate, nenitrile, carboxylic acid, ester,and little terpene in essential oil of Brassica rapa L..
