摘要:

应用水蒸气蒸馏法从多花红千层（Callistemon speciosus）叶提取挥发油，利用气质联用仪(GCMS)分离鉴定，采用GC峰面积归一法确定其相对含量。挥发油得率为1.34%；分离出29个组分，鉴定了其中的21种化合物，占色谱总馏出峰面积的90.303%，其主要成分是1,8桉叶素(31.987%)、α松油醇(14.059%)、β硝基乙醇(13.264%)、瓜菊醇酮(9.246%)、松油醇4(6.038%)等。

Abstract:

The essential oil was extracted from the leaves of Callistemon speciosus with the steam distillation method. The chemical constituents were identified by the gas chromatographymass spectrometry (GCMS), and the content of each chemical constituent was calculated with the peak area normalization method. The yield of the essential oil was 1.34%. 29 components were separated. 21 components were identified, which accounted for 90.303% of the essential oil. The main compounds included 1,8cineole (31.987%),αterpineol (14.059%),βnitroethanol (13.264%), cinerolone (9.246%), and 1terpinen4ol (6.038%).

Key words: Callistemon speciosus, chemical components, essential oil, gas chromatogrphy-mass spectrometry (GC-MS)
