Objective: The aim of this study was to analyze the ingredients

and to identify the main ingredients and content of the volatile oil

which extracted from Nanyang Artemisiae Argyi Folium volatile oil by two different solid-phase microextraction (SPME) and supercritical fluid extraction (SFE). Method: The volatile oil was extracted separately from Artemisiae Argyi Folium by SPME and SFE. Then GG-MS was used to analyze it. Result: Thirty-eight components were isolated by SPEM

accounting for 95.17% of the total content

Thirty-five components were with 35 identified by comparing with the mass spectrometry database

while 26 components were isolated by SFE

accounting for 95.26% of the total content

with 25 identified by comparing with the mass spectrometry database. The content of each component varied

with eucaylptole as the most (13.75% and 18.26% respectively). The following components isolated from SPME were including borneol (11.58%)

isoartemisia ketone (7.15%) and esym-dimethylurea (5.12%);the following components from SFE included isoartemisia ketone (12.15%)

borneol (11.38%) and trans-ocimene (7.03%). Conclusion: The result verified the superiority of the SPME method

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