柠檬叶挥发性成分分析

Study on the chemical constitents of Citrus limon leaves oil

用挥发油提取器提取柠檬叶中挥发油,利用气相色谱-质谱分析其中的化学成分,采用GC峰面积归一化法定量,鉴定出29种化合物,占挥发油总量的96.45%以上,主要成分为d-柠檬烯(28.69%)、β-蒎烯(19.77%)、香茅醛(16.82%)、桧烯(5.10%)等。

The essential oil of Citrus limon leaves was extracted by volatile oil content equipment.The chemical compositions and their relative contents were quantitatively and qualitatively analyzed by means of GC-MS and GC.29 compounds were identified,which comprised more than 96.45％ volatile fraction.The major compounds were d-limonene （28.69％）,β-pinene （19.77 ％）,citronellal （16.82％）,sabinene （5.10％）,etc.
