摘　　要：为提高精油得率,优化亚临界萃取光皮木瓜[Chaenomeles sinensis(Thouin)Koehne]果皮精油的工艺,在单因素试验基础上,通过响应面试验优化光皮木瓜果皮精油亚临界萃取工艺条件,研究了亚临界萃取的光皮木瓜果皮精油对DPPH·和ABTS自由基的抑制率。结果表明,优化后的光皮木瓜果皮精油亚临界萃取条件为萃取温度30℃、萃取时间27 min、萃取次数3次,光皮木瓜果皮精油平均得率为4.16%。光皮木瓜果皮精油对DPPH·和ABTS自由基的半抑制浓度IC_(50)分别为73.5 mg/L和93.5 mg/L。To improve the yield of essential oil and optimize the subcritical extraction process of Chaenomeles sinensis(Thouin)Koehne peel,on the basis of single factor experiments,the subcritical extraction process conditions of Chaenomeles Sinensis(Thouin)Koehne peel essential oil were optimized by response surface experiments,and the inhibition rate of DPPH·and ABTS free radicals of Chaenomeles Sinensis(Thouin)Koehne peel essential oil were studied.The results showed that the optimum extraction conditions were as follows:extraction temperature 30℃,extraction time 27 min and extraction 3 times.Under this condition,the yield of essential oil was 4.16%.The IC50 values of essential oil on DPPH·and ABTS free radicals were 73.5 mg/L and 93.5 mg/L respectively.
