The antioxidant and antiradical activities of sulfur containing phenols which are analogues of probucol in comparison with alpha-tocopherol and BHT were tested using initiated methyl oleate oxidation model. The antioxidant effect linearly increased with increasing concentration of phenols. The ability of investigated phenols to destroy and reduced accumulation of hydroperoxides is revealed. The combined inhibitory effects of composition most effective researched antioxidant--CO-3--with alpha-tocopherol for the first time are described.
