Abstract:
Objective:To investigate the antioxidant activity of the total flavonoids of Cinnamomum septentrionale Hand.-Mzt. Methods:A ferricyanide reduction method was used to study the reduction ability. The scavenging activity of the total flavonoids on DPPH· free radical( DPPH·),hydroxyl radicals( ·OH)and superoxide anion free radical( O2-·)was investigated as well. Re-sults:Cinnamomum septentrionale Hand.-Mzt. had good reduction and scavenging activity on the free radicals in a concentration-de-pendant manner. When the concentration of total flavonoids of Cinnamomum septentrionale Hand.-Mzt reached 0. 15 mg·ml-1 ,86%of DPPH free radical( DPPH·),68% of hydroxyl radicals( ·OH)and 59% of ultra oxygen anion free radical( O2-·)were scav-enged. Conclusion:Cinnamomum septentrionale Hand.-Mzt. has good antioxidant activity,and as a natural antioxidant,it is worthy of further research and development.
