Antioxidant activities of tocopherols on Fe2+-ascorbate-induced lipid peroxidation in lecithin liposomes

Abstract

The antioxidant activities of 4 tocopherols, tocol, and a water-soluble model analog of α-tocopherol were compared. Egg lecithin liposomes were used and oxidation was catalyzed by Fe2+-ascorbate. The activities decreased in the order α->β->γ->δ-tocopherol>tocol, in agreement with their potencies in vivo. The water-soluble analog was the least effective… (More)
