OBJECTIVE
To provide scientific methods for quality criterion by studying the chemical components of essential oil from Baeckea frutescens.
METHOD
The chemical components of essential oil from B. frutescens were identified by GC-MS-DS, TLC and capillary GC. The relative contents of main components were determined by area normalization.
RESULT
More than 50 peaks were separated, and 38 components were identified, which accounted for over 94% of the total GC peaks areas of the essential oil. The methods for quality evaluation of essential oil from B. frutescens by TLC and capillary GC were established.
CONCLUSION
The chemical components of essential oil from B. frutescens collected from different habitats and collecting periods have common characteristics as well as differences. Some components, such as linalool, can be used as a standard and chromatography fingerprint to analyze the quality of essential oil from B. frutescens.
目的
通过对岗松挥发油化学成分的研究，为其质量标准提供科学依据。
方法
采用气相色谱-质谱-数据系统联用（GC-MS-DS）、薄层色谱（TLC）及毛细管气相色谱法对岗松挥发油的化学成分进行鉴定，用面积归一化法测定主要成分的相对含量。
结果
分离出50多个峰，鉴定出38种成分，占挥发油总GC峰面积的94%以上。建立了岗松挥发油的TLC及毛细管GC质量评价方法。
结论
不同产地、不同采收期岗松挥发油的化学成分既有共性又有差异。其中一些成分，如芳樟醇，可作为分析岗松挥发油质量的标准及色谱指纹图谱。
