摘　　要：采用Clevenger法提取草果精油,以1.87%的平均得油率获得精油,用GC-MS联机对精油进行了成分分析,检测出38种成分,解析鉴定了占总成分98.393%的32个成分。主要成分1,8-桉树脑占40.891%(相对含量,以下同),α-水芹烯9.769%,2-异丙基苯甲醛6.988%。测定精油清除NaNO2能力结果可知:当精油用量为0.15～0.45 mL时,清除率为68.22%～81.40%,大于对照物Vc(57.12%～78.16%)和BHT(14.64%～18.66%)(精油和对照物浓度10 mg/mL)。The essential oil was obtained in 1.87% y/eld from Amwwan tsao-ko by clevenger method. The chemical components of the essential oil were analyzed by GC-MS. 38 components were detected and 32 compounds which occupied 98. 393% （relative content） of the total constituents were identified. The main components were 1,8-cinecl （40. 891% ） ,a-phel-landrene （9.769%） and 2-isopropylbenzaldehyde （6. 988% ）. The ability of scavenging sodium nitrite of essential oil was investigated. The results showed that the essential oil had considerable effect of scavenging NaNO2 ,the scavenging rate were 68.22%-81.40% when 0.15-0.35 mL of the oil was used. It was higher than Vc （57. 12%-78. i6%） and BHT （14.64%-18.66% ） which were used as controls （conc/entraetion of essential oil, Vc and BHT are 10 mg/mL）.
