摘　　要：Both essential oils of fresh and air-dried Asarum caulescene （Maxim.） were analyzed by GC-MS in three different polarities. The resuits show that thirty-four components were identified in the oils, and main compounds of both oils were β-pinene （7. 63% vs. 20. 77%）, 2 carene （8.94% vs. 7.99%）, β-phellandrene （7.80% vs. 14.39%）, 1,8-cineole （8. 91% vs. 13. 29%） and germacrone （46. 64% vs. 6.64%）, however, the content of monoterpene hydrocarhons（30.29% vs. 52. 30%） and oxygenated sesquiterpenes（47.69% vs. 10.65%） of both oils was different. The antimicrobial activity of the oil was evaluated against 3 fungi and 11 hacteria including 7 clinical isolated strains. Our results showed that both oils presented a broad antimicrobial spectrum, and compared with the essential oil from fresh herb, the extracted oil from dried herb had hetter antimicrohial activity, its minimum inhibitory concentration（cmi） values of dried herh were 0. 16-2. 5 g/L and lowest minimum bactericidal concentration（cmb ） value was 0.31 g/L.Both essential oils of fresh and air-dried Asarum caulescene （Maxim.） were analyzed by GC-MS in three different polarities.
