Objective：To analyze the different ingredients and identify the main ingredients and content of the volatile oil，which extracted from Nanyang Artemisa argyi volatile oil by two different methods: solid-phase microextraction (SPME) and supercritical fluid extraction ( SFE)

and analyse them. Method：The volatile oil was extracted separately from Artemisa argyi leaves by SPME and SFE. Then GG-MS was used to analyze it. Result：38components was identified by SPEM

accounting about 95.17% ，26 components was identified by SFE

accounting about 95.26%. 35kinds of compoments was identified by comparing with the Mass spectrometry data base from the former

and 25 from the latter. The content of each component was different

but most contents of which was Eucaylptole (18.26% and 15.35% respectively). There are other components from SPME

include borneol(11.58%)、isoartemisia ketone(7.15%) and esym-dimethylurea(5.12%); the same as from SFE include isoartemisia ketone(12.15%)、borneol(7.15%) and trans-ocimene(7.03%).Conclusion：The result verify the superiority of the way of SPME

though the components of the volatile oil eatracted by two different ways are obviously different .
