摘　　要：目的:分析黄芩花、茎叶、根和种子挥发油成分的差异。方法:采用共水蒸馏法分别提取黄芩不同器官中的挥发油,用气相色谱-质谱联用(GC-MS)技术并结合Kovats保留指数(KI)对比法对挥发油化学成分进行分析鉴定,运用面积归一化法确定各组分相对含量。结果:黄芩花中鉴定出53种化合物,占花挥发油总量的91.16%;茎叶中鉴定出48种化合物,占茎叶中挥发油总量的88.48%;根中鉴定出39种化合物,占根中挥发油总量的91.79%;种子中鉴定出32种化合物,占种子挥发油总量的84.58%。结论:黄芩花、茎叶、根和种子挥发油的成分和相对含量各不相同,均含有大量的活性成分,具有较高的应用潜力和综合开发前景。Objective：To evaluate the differences among essential oils from the fresh flowers,stem leaves,roots and seeds of Scutellaria baicalensis.Methods： The oils was obtained by hydrodistillation and identified by gas chromatography-mass spectrometry（GC-MS） and the Kovats retention index.The relative contents of the components were determined by the peak-area normalization method adopted in gas chromatography.Results： Fifty-three compounds constituting 91.16% of flower oil,forty-eight compounds comprising 88.48% of stem-leaf oil,thirty-nine compounds representing 91.79% of root oil and thirty-two compounds accounting 84.58% of seed oil have been identified.Conclusion： The results showed that the components and relative contents of the essential oils among flowers,stem leaves,roots and seeds have significant differences.Each of them had a great range of potential utilities and a prospect of development.
