Peroxyl Radical Scavenging Ability of Fifty kinds of Chinese Medicines Determined by an ESR Spin-trapping Technique

摘要：

　　The peroxyl radical scavenging abilities of fifty Chinese herbal medicines were determined accurately by an electron spin resonance (ESR) spin-trapping technique using 5,5-dimethyl-1-pyrroline 1-oxide (DMPO) as a spin-trapping reagent.The peroxyl radical was generated by the thermolysis reaction of 2,2-Azobis(isobutyronitrile) (AlBN) in the presence of the spin-tap DMPO and with or without sample.As a result of these studies,a strong scavenging ability of peroxyl radical was found in Chinese medicines for diseases of anti-aging and blood circulation.
