摘要
目的：比较研究不同产地花椒的挥发油含量和组成。方法：以水蒸气蒸馏法提取挥发油，挥发油测定器测定含量，采用气相色谱．质谱联用法（GC-MS）检测，运用自动质谱退卷积定性系统（AMDIS）结合Kovats保留指数对其化学成分进行分析。结果：6批花椒的挥发油含量在1．52～3．410mL·100g^-1。6批挥发油样品共鉴定出68个化合物，其中5批样品含量最高的化合物为芳樟醇，其含量在24.28～42．10％；1批样品含量最高的化合物为乙酸芳樟酯，其含量为32．52％。结论：不同产地的花椒在挥发油含量及组成上均存在一定差异。
Objective： Study on volatile oil composition and content of Zanthox＇ylum bungeanum Maxim. from different origin. Method： The volatile oil was extracted by steam-stilling method.The chemical constituents of the volatile oil were detected by GC-MS and analyzed by AMDIS combined with Kovatts retention index. Result： The volatile oil content of 6 batches of Zanthoxylum bungeanum Maxim. was between 1.524 mL·100g^-1 and 3.410 mL·100g^-1. 68 compounds in the volatile oils of six batches were identified. The highest level compound of five batches of Zanthoxylum bungeanum Maxim. was linalool of 24.28 %- 42.10%. The highest level compound of another batch of Zanthoxylum bungeanum Maxim. was linalyl acetate of 32.52%. Conclusion： The content and composition of volatile oil of Zanthoxylum bungeanum Maxim. of different origin is different.
