摘 要:目的:采用GC-MS分析广西细叶桉叶及果实挥发油的成分。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NIST98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法测定其相对百分含量。结果:细叶桉叶挥发油共鉴定出了39个化合物,占挥发油总成分的96.69%,主要成分为桉油精(27.93%)、1R-α-蒎烯(22.60%)、异松香芹醇(8.71%)等;细叶桉果实挥发油共鉴定出了36个化合物,占挥发油总成分的93.50%,主要成分为1R-α-蒎烯(32.88%)、桉油精(13.64%)、D-柠檬烯(8.31%)等。结论:该法简便、快速、灵敏度高。Objective : To Analyse the chemical composition and their relative contents of essential oil from the leaves and fruits of Eucalyptus tereticornis in Guangxi prvince. Methods : The column temperature was controlled by a program with a capillary column HP-5 MS, and the MS analysis was performed with EI and quadrupole mass analyzer. The chemical compositions were identified by NIST98 searching and mass spectra comparing, and their relative contents were determined by using normalization method of chromatographic peak areas. Results : 39 compounds constituting 96. 69% of the oil of leaves were identified. The major components were eucalyptol (27. 93% ), 1R-α-pinene (22. 60% ), isopinocarveol (8.71%) ; 36 compounds constituting 93.50% of the oil of fruits were identified. The major components are 1R-α-pinene (32. 88 % ), eucalyptol (13.64%), D-limonene (8.31% ). Conclusion: The GC-MS is a simple, rapid and sensitive method.
