Both of them showed no toxic effect on mice at the testing dose of 10 mg/kg. The 2,2-diphenyl-1-picrylhydrazyl free radical scavenging test showed that both of the formicary extracts were potent radical scavengers and their scavenging activities were dose-dependent. Furthermore, at higher concentrations (5～10 mg/ml) both of them exhibited significantly higher DPPH scavenging activity than butylated hydroxytoluene.
