摘要(Abstract):

[Objective] This study was undertaken to extract flavonoids from cherry leaves and to investigate the anti-oxidative activity in vitro. [Methods]The scavenging action on OH·and O-2·and its inhibiting effect on oxidative hemolysis of erythrocyte induced by H2O2and lipid peroxidation of hepatic tissue in mice were investigated in vitro. [Results] The flavonoids showed concentration-dependent scavenging effect on OH·and O-2·. The flavonoids also showed remarkable inhibiting effects on oxidative hemolysis of erythrocyte in mice induced by H2O2. When the final concentration of the flavonoids reached 30%,the inhibition rate was 74. 13%. It could inhibit lipid peroxidation of hepatic tissue in mice induced by vitamin C with low concentration and ferrous sulfate. And the inhibiting effect was concentration-dependent.When the final concentration of the flavonoids reached 30%,the inhibition rate was 68. 33%. [Conclusions]The total flavonoids from cherry leaf have concentration-dependent antioxidant activity in vitro.
