| Abstract: | The essential oils were obtained in yields of 1. 12% and 1.87% from Amomum tsao ko by steam distillation - dieth yl ether extraction and Clevenger method respectively. The chemical components of two essential oils were analyzed by GC/ MS. When the essential oil obtained by steam distillation - diethyI ether extraction method was analyzed, 30 components were detected and in which 29 components that occupied 99. 619% （relative content, and so on） of the total constituents were（dentifled, the main components were 1 , 8 eineol （ 41. 433% ）, a-phellandrene （ 7. 882% ） arid 2 isopropylbenzaldehyde （ 5. 930% ）. For the essential oil obtained by Clevenger method, a total of 38 components were detected, in whieh 32 components that account for 98. 395% were identified. The main components were 1,8-cineole （41）. 891%） （mass fraction）, ce phellandrene （9.769%） and 2-isopropylbenzaidehyde （6.988%）. The ability of scavenging DPPH of both essential oils were studied, and the result showed that they had considerable effect of scavenging DPPH, the scavenging rate were 80. 0% and 75.8%, respec- tively, when 10. 0 mg/mL of oils were used. |
