摘　　要：[Objectives] To study the in vitro antioxidant activity of resveratrol in peanut shell.[Methods] The crude extracts and purified substances were obtained by ultrasonic extraction and extraction,respectively.The scavenging ability and reducing ability of DPPH free radicals,hydroxyl radicals and superoxide radicals were studied and compared with BHT and Vc.[Results]Regardless of crude extract or purified substances,resveratrol in peanut shells had reducing ability,but the crude extract had greater reducing ability than purified substances,Vc and BHT,and the purified substances had greater reducing ability than BHT.At the same concentration,the effects of purified substances on scavenging DPPH free radicals were better than BHT,and the scavenging rate of crude extracts for superoxide radicals was higher than BHT,purified substances,and Vc;the purified substances had certain scavenging effects on the DPPH free radicals,hydroxyl radicals and superoxide radicals;the scavenging effects of crude extract on superoxide radicals increased with the increase of the concentration,but the scavenging effects on DPPH free radicals and hydroxyl radicals dropped with the increase of the concentration.[Conclusions]Crude extracts and purified substances of resveratrol in peanut shell have antioxidant activity.[Objectives] To study the in vitro antioxidant activity of resveratrol in peanut shell.[Methods] The crude extracts and purified substances were obtained by ultrasonic extraction and extraction,respectively.The scavenging ability and reducing ability of DPPH free radicals,hydroxyl radicals and superoxide radicals were studied and compared with BHT and Vc.[Results]Regardless of crude extract or purified substances,resveratrol in peanut shells had reducing ability,but the crude extract had greater reducing ability than purified substances,Vc and BHT,and the purified substances had greater reducing ability than BHT.At the same concentration,the effects of purified substances on scavenging DPPH free radicals were better than BHT,and the scavenging rate of crude extracts for superoxide radicals was higher than BHT,purified substances,and Vc;the purified substances had certain scavenging effects on the DPPH free radicals,hydroxyl radicals and superoxide radicals;the scavenging effects of crude extract on superoxide radicals increased with the increase of the concentration,but the scavenging effects on DPPH free radicals and hydroxyl radicals dropped with the increase of the concentration.[Conclusions]Crude extracts and purified substances of resveratrol in peanut shell have antioxidant activity.
