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.
