The antioxidative effects of the six commercial lecithins, tocopherols, citric acid and ascorbyl palmitate on refined perilla oil were inverstigated by active oxygen method ($AOM,\;hrs\;at\;97.8^{\circ}C$) and oven test. Except for the lecithin I (aceton insoluble content 55%), the induction time on perilla oil treated with commercial lecithins at 5% level was longer than that of refined soybean oil. When the concentration of lecithin (0.5, 1, 2.5, 4 and 5%) in perilla oil was increased, enhanced the antioxidative effect at AOM and oven test. Lecithin also showed synergistic effect with the mixtures of tocopherol, citric acid and ascorbyl palmitate. The antioxidative effect of ${\gamma}-rich-tocopherol$ on perilla was higher than that of ${\dalta}-rich-tocopherol$ or mixed tocopherol.
