[Objective] To study the scavenging effects of Rutin and lipase Novozym 435 synthesized rutin fatty acid ester on ·OH and O2-·. [Method]The UV spectrophotometer was adopted to determine the scavenging effects on ·OH and O2-·. [Result] Rutin and its fatty acid ester had certain scavenging effects on ·OH and O2-·, the scavenging effect of rutin on ·OH and O2-·could achieve 50% with the concentrations of 1.711 mg/ml and 1.423 mg/ml respectively(EC50), While the concentrations of rutin fatty acid ester called for 0.893 3 mg/ml and 1.358 mg/ml to achieve the same effects. [Conclusion]Rutin fatty acid ester could scavenge ·OH and O2-· effectively, which was superior to mannitol under the same conditions.
