[Analysis of volatile oil in Fructus Aurantii processed with Zhangband method by GC-MS].

Objective: To analyze the chemical components of the volatile oil in processed pieces of Fructus Aurantii (PPFA) with JiangXi Zhangband methods by GC-MS.

Methods: The volatile oil was obtained from PPFA by steam distillation. The amount of the components from the volatile oil were determinated by area normalization method. The separated components were identified by GC-MS.

Results: Composed of the total volatile oil over 90% , 70 components were separated and identified. All of the processed Fructus Aurantii produced new chemical composition, in the meantime,the contents were changed in some chemical composition after processed.

Conclusion: The method is reliable, stable and has good repeatability. This method can be applied to the analysis of volatile oil components in PPFA. It will provide the certain scientific methods for further evaluating of PPFA quality.
