Analysis of the Chemical Constituents of Essential Oil from the Leaves of Callicarpa integerrima

目的:分析全缘叶紫珠叶挥发油化学成分。方法:应用气相色谱-质谱联用仪进行分离鉴别。结果:鉴定出42种化学成分,占总挥发油的97.62%。结论:挥发油中β-石竹烯(33.74%)、甘香烯(12.86%)、τ-杜松烯(9.57%)和(-)-斯巴醇(8.99%)为主要成分。此外,古巴烯(4.21%)、兰桉醇(3.81%)、α-石竹烯(2.48%)、十氢-α,,α4 a-三甲基-8-亚甲基-[2R-(2α,4a,α8 aβ)]-2-萘醇(2.37%)和1,6-环癸二烯(2.24%)的含量也较高。

Objective：To analyze the compositions of the essential oil from the leaves of Callicarpa integerrima.Methods：GC-MS method was used.Results：42 chemical constituents,accounting for 97.62% of total content were identified.Conclusion：The main components were β-caryophyllene（33.74%）,Elixene（12.86%）,τ-Cadinene（9.57%） and（-）-Spathulenol（8.99%）.Besides,some sesquiterpenes and their oxides,such as Copaene（4.21%）,Globulol（3.81%）,α-Caryophyllene（2.48%）,2-Naphthalenemethanol,decahydro-α,α,4a-trimethyl8-methylene-[2R-（2α,4aα,8aβ）]-（2.37%） and 1,6-Cyclodecadiene（2.24%） had also relatively high contents.
