| الوصف: | In the present study, the anti-lipoperoxidant activity of some phenolic acids, flavonoids and purified tannins from Quercus sp. was determined. Phenolic acids (10, 25 and 50 µg / ml) inhibited lipid peroxidation by 42 – 51%. Caffeic acid seems to be the most potent inhibitor among phenolic acids. Tannic acid, a commercially available tannin, inhibited lipid peroxidation in the same manner as phenolic acids. The inhibition did not exceed 43%.Catechin and quercetin significantly inhibited lipid peroxidation at all tested concentrations and the percentages of inhibition varied between 38 and 60%. However, flavonoid glycosides (rutin and diosmin) did not behave in the same way. Quercus purified tannins showed high inhibition of lipid peroxidation. The observed inhibition was not significantly related to the concentration. Among the four tested tannins, castalagin gave the smallest rate of inhibition (53.9%) versus acutissimin B (65.5%).
