The antioxidant effects of aqueous green tea extracts with $alpha$-tocopherol and lecithin dissolved in lard were investigated on the lipid metabolism in serum and liver of Sprague-Dawley male rats. Elderly male rats were fed for 8 weeks by different experimental diets containing 10% lard(w/w), 0.5% aqueous green tea extracts, 0.05% $alpha$-tocopherol and 1.0% lecithin. By the addition of the mixture of the antioxidants, the level of total cholesterol. HDL-cholesterol and triglyceride in serum and liver were not changed. The activities of glutathione peroxidase were significantly increased in the case of addition of the antioxdant mixtures but the activities of superoxide dismutase and glutathione S-transferase were not affected.
