Objective:To study on the antioxidant activity of Schisandrae Chinensis Fructus red pigment.Method:With UV-V is spectrophotometry
compared with vitamin C(VC) and vitamin E(VE)
the antioxidant activity of Schisandrae Chinensis Fructus red pigment was studied by measuring its scavenging effects on 1
1-Diphenyl-2-picrylhydrazyl radical(DPPH ·)
hydroxyl radical(· OH) and superoxide radical(O-2 ·).Result:Antioxidant activity of Schisandrae Chinensis Fructus red pigment with EC50as index
the results were 27.95 mg · L-1(scavenging DPPH ·)
98.03 mg · L-1(scavenging · OH) and 154.27 mg · L-1(scavenging O-2 ·).Its scavenging effects on radicals were not significant with VC
but much stronger than VE.Conclusion:Schisandrae Chinensis Fructus red pigment has strong antioxidant activity and shows a significant dose-effect relationship.
