GC-MS-AMDIS结合保留指数分析花椒、竹叶花椒挥发油的组成成分

Analysis on Essential Oil from Zanthoxylum bungeanum and Z. armatum by GC-MS-AMDIS Combing with Kováts Retention Index

目的：研究不同产地的花椒和竹叶花椒挥发油组成成分及相对含量.方法：采用水蒸气蒸馏法提取挥发油,用气相色谱-质谱联用法（GC-MS）和自动质谱退卷积定性系统（AMDIS）结合Kováts保留指数（Retention index,RI）对其化学成分进行检测分析.结果：8批样品共鉴定出86个化合物,其中2批四川产花椒含量最高的化合物为芳樟醇,其含量分别为36.25％,30.91％;2批陕西产花椒含量最高的化合物为柠檬烯,其含量分别为15.63％,17.23％;4批竹叶花椒含量最高的化合物均为芳樟醇,其含量在71.74％ ～75.03％.结论：花椒挥发油和竹叶花椒挥发油的组成结构之间差异显著;四川产花椒和陕西产花椒可能分属两个不同的化学型.

Objective：Study on volatile oil composition and relative content of Zanthoxylum bungeanum and Z.armatum from different origin.Metho.d：The volatile oil was extracted by steam-stilling.The chemical constituents of the volatile oil were detected and analyzed by GC-MS-AMDIS combing with Kováts retention index.Result：A total of 86 compounds in the essential oils of eight batches were identified.The highest level compound of two batches of Z.bungeanum from Sichuan is linalool,which represented 36.25％ and 30.91％,respectively.The highest level compound of two batches of Z.bungeanum from Shaanxi is limonene,which represented 15.63％ and 17.23％,respectively.The highest level compound of Z.armatum is linalool,accounting for 71.74％-75.03％.Conclusion：The volatile oil of Z.bungeanum and Z.armatum is significantly different; Z.bungeanum,which come from Sichuan and Shaanxi may belong to two different chemical types.
