Extracts of antioxidants from foods were found to behave differently in a lipsome model for antioxidant activity. According to recent research from England, "The effects of mixtures of antioxidants on the oxidation of phospholipids have been investigated in large unilamellar liposomes following initiation by 2,2'-azobis(2-aminopropane) dihydrochloride. The lag phase increased linearly with antioxidant concentration. The lag phases of mixtures containing alpha-tocopherol with ascorbic acid showed synergy between the antioxidants, but mixtures of beta-carotene with cc-tocopherol or ascorbic acid were not synergistic. "The liposome system was used to...
