Abstract: 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.

Key words: Chaenomeles Sinensis (Thouin) Koehne peel, essential oil, subcritical extraction, antioxidant activity
