柠檬醛和桉叶油素的新资源植物

NEW RESOURCE PLANTS FOR CITRAL AND CINEOLE

摘要: 对湖北川桂叶油等四个样品的化学成分,使用毛细管气相色谱/质谱/计算机联用系统进行分析。结果表明,其中三个样品富含柠檬醛:长阳产川桂叶油(含77.99%)、咸丰产川桂叶油(含86.47%)和湖北樟叶油(含95.01%)。另外,樟树油樟型的叶油中,主要成分为1.8-桉叶油素,含量高达65.76%。这几种樟属植物是湖北的常见树种,资源丰富,鲜叶出油率较高,可供开发利用。

Abstract: The essential oils were extracted by steam distillation from fresh leaves of 3 species of Cinnamomum collected from west Hubei. 4 samples of essential oils, prepared respectively from different producing area, were examined qualitatively and quantitatively by the methods of capillary GC/MS/DS on Finnigan-4510 type. As the result, the major component of 3 samples is citral——the essential oil of C. wilsonii produced from Changyang County contains it 77.99%, the essential oil of C. wilsonii produced from Xianfeng County contains it 86.47% and the essential oil of C. bodinieri var. hupehanum contains it 95.01%. The major component of the essential oil of C. Camphora is 1,8-cineole (65.76%).
