[Objective] The research aimed to compare the scavenging abilities of total flavone from Lygodium japonicum with different solvents to free radical activity.[Method] DPPH method,pyrogallol method and Fenton reaction were used to study the scavenging ability of extracts with 95% ethanol,ethyl acetate,acetone,acetic acid,chloroform,methanol to free radical activity.[Result] Six kinds of solvent extracts from L.japonicum had certain scavenging ability to DPPH·,OH · and O2-·.The scavenging ability of extracted with different solvents to free radicals were difference.The extracts from L.japonicum with 95% ethanol had the best scavenging effects on three kinds of free radicals.[Conclusion] L.japonicum can be used as antioxidants for the development and utilization of resources.
