摘　　要：目的:分析研究光果莸挥发油的主要化学成分。方法:采用共水蒸馏法分别提取光果莸茎、叶和花的挥发油,应用气相色谱-质谱联用(GC-MS)技术并结合Kovats保留指数(K I)对比法对挥发油化学成分进行了鉴定,运用面积归一化法确定了各组分的相对含量。结果:从茎、叶及花中分别鉴定出13、48和42种成分。其中花和叶中的主要成分及相对含量均相似,分别为桃金娘烯醛(2.73%,1.69%)、反-乙酸松香芹酯(46.69%,55.48%)、乙酸桃金娘烯酯(1.17%,1.42%)、β-柏木烯(1.62%,3.21%)及石竹烯氧化物(1.67%,2.73%)等。茎中的化学成分与花和叶中化学成分的相差较大,主要成分为反-乙酸松香芹酯(24.19%)、棕榈酸(47.32%)和植醇(0.77%)等。结论:光果莸茎、叶及花的挥发油均含有大量的活性成分,具有较高的应用潜力和综合开发前景。Objective： To study the main chemical components of essential oils from Caryopteris tangutica. Methods： The chemical compositions of essential oils obtained by hydrodistillation from different organs of Caryopteris tangutica were separately analyzed and i- dentified by GC-MS and Kovats retention index. The relative contents of the components by the peak-area normalization method adopted in gas chromatography. Results： 13,48 and 42 components were separately identified from stems, leaves and flowers. The components and relative contents of the leaves were similar with the flowers, and the main constituents were Myrtenal（ 2. 73%, t. 69% ）, trans-Pinoearvyl acetate（46. 69% ,55.48% ）, Myrtenyl acetate （ 1.17%, 1.42% ） ,β-Cedrene （ 1.62%, 3.21% ）, Caryophyllene oxide （ 1.67%, 2.73%）and so on. The components of the stems were different from others, and the main constituents were hexadecanoie acid （47. 32% ） ,trans-Pinocarvyl acetate（24. 19% ） ,phytol（0. 77% ）. Conclusion：The components and relative contents of the essential oils among stems,leaves and flowers were distinctly different,and each of them had a great range of potential utilities and a prospect of development.
