The essential oil in Zanthoxylum Bungeanum Maxim was extracted by steam distillation and the distilled liquid was collected by passing through chloroform. The aqueous phase was extracted with chloroform sufficiently. The chloroform solution containing the constituents of essential oils was analyzed by gas chromatography-mass spectrometry(GC-MS). Seventeen peaks were separated by gas chromatography, and 16 of them were identified by MS with "Nist98.L" Mass Spectral Data Registry. The structures of the constituents were further verified by manual analysis. The identified constituents accounted for 97% of the peak areas of the essential oils on total ion chromatogram. The major chemical constituents of them are C9, C10 alcohols and alkenes.
