This study was done to determine the effect of antioxidants added perilla oil diet on the content of cholesterol, vitamin E, and lipid peroxide in serum and tissue of rats. Four groups of experimental diets, such none added perilla oil diet, ascorbic acid added perilla oil diet, vitamin E added perilla oil diet, EDTA added perilla oil diet were fed ad libitum to the 4 weeks white male rats of Sprague-Dawley strain. The results obtained are summarized as follow: 1) The body weight gain in all experimental diet groups was higher than the control gorup and EDTA added diet group was lower than the other experimental diet group, while food intake in vitamin E added diet group was the highest and vitamin C added diet group was the lowest in the control group. 2) Total cholesterol levels in serum of all experimental diet groups were lower than that of the control group and especially the level of total cholesterol in none added diet group and vitamin C added diet group were significantly lower than that of control group. 3) HDL-cholesterol levels of all experimental diet groups were lower than that of the control group and especially none added diet group was significantly lower than that of control group. 4) The activities of glutamic oxaloacetic transaminase (GOT) in serum of all experimental diet group except EDTA added diet group were higher than that of the control group and especially none added diet group was significanly higher than that of the control group. The activites of glutamic pyruvic transaminase (GPT) in serum of all experimental diet groups except vitamin C added group were higher than that of control group. 5) Vitamin E levels in serum of none added diet group and vitamin C added diet group were lower than that of the control group and vitamin E added diet group and EDTA added diet group were higher than that of the control group. 6) Vitamin E levels in liver of all experimental diet groups were higher than that of control group and especially none added diet group and vitamin E added diet group were significantly higher than that of the control group. 7) Lipid peroxide in serum of all experimental diet group were lower than that of control group and especially EDTA added diet group. 8) Lipid peroxide in liver and spleen of all experimental diet groups were higher than that of the control group and lipid peroxide in kidney of all experimental diet groups except EDTA added diet group were higher than that of the control group. Four these results, as vitamin C, vitamin E and EDTA added diets have an effect to lipid peroxide by antioxidants, it could be suggested that perilla oil diet has required to add antioxidant because it has not sufficient vitamin E for antioxidant and intake and overtake level of perilla oil diet should be studied to go ahead.
