不同产地防风挥发油的GC-MS分析

Analysis of the Volatile Oil from Saposhnikovia divaricata in Different Habitats by GC-MS

目的:分析10个不同产地来源防风挥发油的主要化学成分,为其质量评价提供依据。方法:采用水蒸气蒸馏法从防风中提取挥发油,用气相-质谱联用仪检测不同产地防风挥发油的化学成分。结果:不同产地防风挥发油均含有人参醇、9,12-十八碳二烯酸、十六酸、油酸、匙叶桉油烯醇、肉豆蔻醚、庚醛、辛醛、壬醛、2-壬酮、桉油脑等11种化合物,其中防风挥发油中的特征成分人参炔醇以10号黑龙江的相对含量最高(60.87%),2号云南的相对含量(59.15%)次之,8号内蒙古防风相对含量(6.69%)最低。结论:不同来源防风挥发油中共有11个共有成分,但各成分含量在不同来源的防风挥发油中有一定差别。

Objective：To analyze the chemical constituents of volatile oil from Saposhnikovia divaricata in 10 different habitats and provide scientific basis for its quality control.Method： The components of volatile oil were separated and identified by GC-MS.Result： There were 11 common constituents in different habitats which were panaxynol,9,12-octadecadienoic acid（Z,Z）-,hexadecanoic acid,oleic acid,（-）-spathulenol,myristicim,heptanal,octaldehyde,nonanal,and et al.The maximum content of panaxynol was 60.87% in No.10 Heilongjiang＇s,then was 59.15% in No.2 Yunnan＇s,and No.8 Neimenggu＇s 6.69% was minimum.Conclusion： There were 11 common compounds in ten volatile oil,but the chemical consituents of volatile oil were different in different habitats.
