摘　　要：对乌饭树(Vaccinium bracteatum Thunb.)叶挥发油进行了GC-MS分析,分离得到65个色谱峰,从中鉴定出49种成分,占挥发油相对含量的91.94%。主要成分为萜类54.75%、开链烷烃6.93%、环烷烃20.13%、烯烃0.60%、芳香烃1.60%、醇酚醚3.39%、醛和酮2.14%、酯1.15%、杂环0.47%、胺0.78%。在萜类中含量最高的有:橙花叔醇20.01%、(Z,Z,Z)-1,5,9,9四-甲基-1,4,7环-十一碳三烯17.99%、石竹烯9.59%。分析表明,乌饭树叶挥发油中含有12种目前已经工业化生产的香精,有5种成分具有驱虫和抑菌作用。The volatile oil from Vaccinium bracteatum Thumb. leaves was analyzed by GC-MS. 65 peaks were separated and 49 compounds were identified, which represented about 91.94 % of the total content. The main chemical constituents were terpenes 54.75 % , open chain alkanes 6.93 % , cycloparaffins 20.13 % , olefins 0.60 % , aromatics 1.60 % , phenol, ether and alcohol 3.39 %, aldehyde and ketone 2.14 %, ester 1.15 %, heterocyclic compounds 0.47 % and amines 0.78 %. Nerolidol 20.01%, （ Z, Z, Z）-1, 5,9,9-tetramethyl-1,4, 7-cycloundecatriene 17.99 % and caryophyllene 9.59 % were the main components in the identified terpenes. 12 kinds of industrial production flavors were found from volatile oil in Vaccinium bracteatum leaves, and five components have insecticide and antibacterial activity.
