摘 要:采用共水蒸馏法分别提取唇形科香薷属鸡骨柴茎、叶、花中的挥发油,用气相色谱-质谱联用(GC-MS)技术并结合Kovats保留指数(KI)对比法对挥发油进行了化学成分对比鉴定,运用面积归一化法确定各组分相对含量。分别从茎、叶、花中鉴定出24、33、42种成分。其中花和叶中的主要成分和相对含量相似,分别为1,8-桉树脑(21.9%,24.73%)、丁香烯(8.79%,8.51%)、γ-松油烯(4.57%,5.11%)、邻伞花烃(3.98%,6.13%)等,其次要成分差异较大。茎中的成分与花和叶中的相差较大,主要成分为棕榈酸(65.05%)、植醇(2.75%)、丁香烯(2.53%)等。结果表明,鸡骨柴茎、叶、花挥发油的成分和相对含量各不相同,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。The chemical compositions of essential oils obtained by hydrodistillation from different organs of Elsholtzia fruticosa (D. Don) Rehd. were separately analyzed and identified by the GC-MS and the Kovats retention index. The relative contents of the components were determined by the peak-area normalization method adopted in gas chromatography. 24,33 and 42 components were separately identified from stems, leaves and flowers respectively. The components and relative contents of the leaves were similar with the flowers,and the main constituents were 1,8-cineole (21.9% ,24.73%),caryophyllene (8.79% ,8.51%),γ- terpinen (4. 57%,5. 11%) and so on. The components of the stems were different from others,and the main constituents were hexadecanoic acid (65.05%), phytol (2.75%) and caryophyllene (2.53 %). The results showed that the components and relative contents of the essential oils among stems,leaves and flowers were distinctly different. Each of them had a great range of potential utilities and a prospect of development.
