Abstract

OBJECTIVE

To Analyze the chemical composition and their relative contents of essential oil from the leaves and fruits of Eucalyptus tereticornis in Guangxi province.

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-alpha-pinene (22.60%), isopinocarveol (8.71%); 36 compounds constituting 93.50% of the oil of fruits were identified. The major components are 1R-alpha-pinene (32.88%), eucalyptol (13.64%), D-limonene (8.31%).

CONCLUSION

The GC-MS is a simple, rapid and sensitive method.

摘要

目的

分析广西窿缘桉树叶和果实挥发油的化学成分及其相对含量。

方法

采用HP-5 MS毛细管柱，程序升温控制柱温，用EI源和四极杆质量分析器进行质谱分析。通过NIST98谱库检索和质谱图对照鉴定化学成分，采用色谱峰面积归一化法测定其相对含量。

结果

从窿缘桉树叶挥发油中鉴定出39种化合物，占挥发油总量的96.69%。主要成分是桉叶油素（27.93%）、1R-α-蒎烯（22.60%）、异松蒎酮（8.71%）；从窿缘桉果实挥发油中鉴定出36种化合物，占挥发油总量的93.50%。主要成分是1R-α-蒎烯（32.88%）、桉叶油素（13.64%）、D-柠檬烯（8.31%）。
