Antioxidation and scavenging effects on free radicals of some extracts from Chinese medicines 1 first-author 1 1 1 2 2 Institute of Radiation Medicine, Suzhou Medical College, Suzhou 215007 Institute of Radiation Medicine, Suzhou Medical College, Suzhou 215007 Biomedical ESR laboratory, Beijing Institute of Radiation Medicine, Beijing 100850 Biomedical ESR laboratory, Beijing Institute of Radiation Medicine, Beijing 100850 The inhibiting effects of Chinonin, Quercetin and Tannic Acid on the lipid oxidation (LPO) induced by irradiation were investigated by means of a modified TBA spectrophotometry. The scavenging effects of these three active compounds on free radicals were studied by ESR technique. The results showed that antioxidation effects of Chinonin and Quercetin were better than that of Tannic Acid; though scavenging effects of the three active compounds were similar. γ-irradiation Chinonin Quercetin Tannic Acid LPO Free radicals ESR References Simic M G , Bergtolo D S.
