祁白芷挥发油成分的GC-MS分析

GC-MS analysis of essential oil from root of Angelica dahurica cv.Qibaizhi

目的:研究祁白芷Angelica dahurica cv.Qibaizhi干燥根的挥发油化学成分。方法:采用水蒸气蒸馏法提取祁白芷挥发油,利用气相色谱-质谱联用技术分析挥发油成分。结果:检出290个色谱峰,鉴定出111个化合物,占挥发油总量的90.61%。结论:祁白芷根挥发油中主要成分为:3-蒈烯(3-carene,12.70%),β-榄香烯(β-elemene,6.20%),β-萜品烯(β-ter-pinene,3.53%),β-香叶烯(β-myrcene,1.97%),γ-榄香烯(γ-elemene,1.82%),β-水芹烯(β-phellandrene,1.65%),β-马阿里烯(β-maaliene,1.61%)等。此外,还检出香豆素类成分软木花椒素(suberosin,0.16%)。

Objective：Essential oil from root of Angelica dahurica cv.Qibaizhi were studied.Method：Essential oil was extracted by water-steam distillation and analyzed by GC-MS.Result：Two hundreds and ninety chromatographic peaks were detected,among which 111 compounds have been identified.The contents of them made up 90.61% of the total essential oil.Conclusion：The main compounds in the essential oil were 3-carene（12.70%）,β-elemene（6.20%）,β-terpinene（3.53%）,β-myrcene（1.97%）,γ-elemene（1.82%）,β-phellandrene（1.65%）,and β-maaliene（1.61%）,et al.In addition,suberosin（0.16%）,a coumarins compound,was also determined.
