摘要

Anti-lipid peroxidation activity,reducing power and chelating power of flavonoid extracts from Oxytropis glabra DC,as well as their elimination effect on DPPH,superoxide anion and hydroxyl radicals were determined in the paper,so as to evaluate in vitro antioxidative activities of flavonoid extracted from O.glabra.The results showed that flavonoid from O.glabra had fairly strong anti-lipid peroxidation.The antioxidation effects on rapeseed oil successively were vitamin C > sample > vitamin E > BHT > CK ;the effects on cottonseed oil successively were sample > vitamin C > BHT > vitamin E > CK;the effects on sunflower oil successively were sample > vitamin C > vitamin E > BHT > CK ;the effects on lard successively were BHT > vitamin C > sample > vitamin E > CK.The samples had stronger clearance rate against DPPH,superoxide anion and hydroxyl radicals than control;the reducing power of sample was weaker than Vitamin C and stronger than Vitamin E;chelating power of sample was weaker than EDTA.Flavonoid from O.glabra had the value for further development and utilization as natural antioxidant.
