Abstract: The volatile components of Artemsia argyi were extracted by steam distillation（SD） and head space solid phase micro-extraction（HS-SPME）,respectively,and their composition and relative content were analyzed by gas chromatography-mass spectrometry （GC-MS）. The results showed that 42 components were separated by SD-GC-MS and 22 components were identified,accounting for 75.95% of the total volatile oil;53 components were separated by HS-SPME-GC-MS and 28 components were identified,accounting for 74.11% of the total volatile components. There are some differences in the volatile components extracted from the two different pretreatment methods of SD and HS-SPME. The combined analysis of the volatile components of folium artemisiae argy can provide more comprehensive information.
