Allii Tuberosi Semen extract(ATSE) was investigated effects of antioxidation for electron donating ability, superoxide dismutase(SOD), nitrate reductase(NR), xathine oxidase(XO) and lipid peroxidase(LP) activity. In vitro, electron donating ability, SOD and NR activity were increased according to the increasing of ATSE concnentrations. Levels of lipid peroxidation were proportionally decreased to concentrations of ATSE. Also, enzyme activity of xanthine oxidase was decreased. However, nitrate reductase activity was significantly increased depends on the higher ATSE concentrations.
These results suggest that ATSE would be prevented lipid peroxidation though removing the oxygen free redicals and nitrate.
