不同产地白豆蔻挥发油成分的GC-MS分析

Analysis of Volatile Constituents in Amomum kravanh from Various Habitats by GC-MS

目的:分析与比较不同产地白豆蔻挥发油的化学成分。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NIST08和Wiley275谱库检索,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:不同产地的白豆蔻挥发油中均含有桉油精、α-律草烯、β-蒎烯、α-蒎烯、α-荜澄茄烯、百里香素等19个化合物,但含量不同。结论:不同产地白豆蔻挥发油的主要成分存在差异。

Objective： To analyze the constituents of volatile oils in Amomumkravanh from various habitats. Method： The column temperature was controlled by a program with capillary column HP-SMS and the MS analysis was performed with EI and quadruple mass analyzer. The chemical composition was identified by NIST08 and Wiley275 library, and their relative contents were determined by using normalization method of chromatographic peak areas. Result： There were 19 common compounds in A. kravanh from various habitats which were eucalyptol, α-caryophyllene, β-pinene, α-pinene, α-cubebene, o-cymene. Conclusion： The main constituents were different in various habitats.
