Effects of Galgeun(Pueraria radix) extracts on plasma and liver lipid composition, liver function and antioxidative capacity were investigated in rat fed high oxidized fat. Plasma total cholesterol and triglyceride concentration increased in the high oxidized fat groups, however these values showed a tendency to decrease in the Galgeun extracts groups. Plasma HDL-cholesterol concentration revealed a tendency to increase in Galgeun extracts groups. The concentration of liver total cholesterol showed no significantly different in all treatment groups, however liver triglyceride concentration showed a tendency to decrease in galgeun extracts groups. Thiobarbituric acid(TBARS) concentration in plasma and liver showed a tendency to decrease in galgeun extracts groups. The galgeun extracts samples have also decreased the plasma GOT and GPT activities, whereas they have increased the liver glutathione peroxidase, superoxide dismutase and catalase activity.
