正骨水化学成分气相-质谱分析

Determination of Zhenggushui by GC-MS

目的:采用气相色谱-质谱(GC-MS)分析正骨水的成分。方法:采用HP-5MS弹性石英毛细管柱,程序升温,以EI离子源和四极杆质量分析器进行分析,质谱图用NIST2002谱库检索,结合人工谱图解析,鉴定各种成分,并用色谱峰面积归一化法测定其相对百分含量。结果:分离出30个色谱峰,鉴定出29种成分,占已分离组分中含量的97%以上。其中左旋樟脑、薄荷脑等是相对含量较高的成分。结论:该方法简便、快速、灵敏度高。

Objective：To analyze the chemical composition and their relative contents of Zhenggushui.Method：Acapillary column HP-5MS was used.The column temperature was controlled by a program and the MS analysis was performed with EI and quadrupolemass analyzer.The chemical composition was identified by NIST2002 searching and mass spectra comparing and their relative contents were determined by using normalization method of chromatographic peak areas.Result：There were 30components were found and 29 of them（more than 97%） were identified.Conclusion：The GC-MS is a simple,rapid and sensitive method for the chemical composition analysis of Zhenggushui.
