山鸡椒不同部位挥发油化学成分的GC/MS分析

Analysis of Volatile Oil from Different Parts of Litsea cubeba

目的:研究山鸡椒各部位挥发油的化学成分。方法:用水蒸气蒸馏提取山鸡椒各部位挥发油,用GC-MS分析和鉴定其化学成分。结果:从其果实、根、叶中分别鉴定出19种(占挥发油总量的93.57%)、17种(占挥发油总量的98.01%)、28种(占挥发油总量的95.33%)化合物。山鸡椒果实挥发油的主要成分是柠檬醛(69.22%)、柠檬烯(8.69%)等,根挥发油的主要成分是柠檬醛(34.70%)、3,7-二甲基-6-辛烯醛(26.56%)、3,7-二甲基-2辛烯-1-醇(21.81%)等,叶挥发油的主要成分是柠檬醛(19.05%)、桉叶油素(13.80%)、α-香茅醇(7.37%)、3,7-二甲基-6-辛烯醛(16.74%)等。结论:山鸡椒各部位挥发油的主要成分和含量均有差异,在入药和研究中都应区别对待。

Objective： To analyze and compare the compounds of the essential oli from the fruits and leaves and roots of Litsea cubeba.Methods： With steam distillation extraction method,Litsea cubeba essential oil was extracted from the fruits and leaves and roots.The qualitative and quantitative analysis of Litsea cubeba essential oil were carried out with GC-MS.Results： 18 compounds were identified from the fruits（93.57% of the total essential oil）and 17 compounds were identified from the roots（98.01% of the total essential oil）and 28 compounds were identified from the leaves（95.33% of the total essential oil）.The main constituents of the fruits essential oil were Citral,Limonene,and so on;The main constituents of the roots essential oil were Citral,6-Octenal,3,7-dimethyl-,2-Octen-1-ol,3,7-dimethyl-,and so on;The main constituents of the leaves essential oil were Citral,Eucalyptol,Citronellol,6-Octenal,3,7-dimethyl-,and so on.Conclusion： The constituents of volatile oil extracted from the different parts of Litsea cubeba were different,so they should be utilized differently in clinical application and study in great depth.
