In this study,the changes of volatile components in different processed Zanthoxylum bungeanum were analyzed, the volatile oil from Z. bungeanum was extracted by steam distillation,the composition and content of volatile components in different processed Z. bungeanum were analyzed by GC-MS. By comparing the volatile components of different processed Z. bungeanum,it was found that the volatile oil of Z. bungeanum could be divided into three categories:alcohols,alkenes and esters. The compounds with high content were linaloyl acetate,linalool and limonene in turn. Among the identified compounds,there are 25 kinds of components in different processed products of Z. bungeanum,among which eucalypt oil is not identified in wine products. The results of this study provide a theoretical basis for further research on the anti-toxic and synergistic effects of Z. bungeanum.
