Heterocyclic amines (HCAs) are food mutagens and carcinogens that are found in cooked fish, meat, and protein-rich foods. This study examined the inhibitory effect of marinades containing a Nelumbo nucifera leaf fraction on HCA formation in cooked beef steak. As a result of the Ames assay, cooked beef marinated with the N. nucifera leaf butanol fraction (2.0 g) cooked at 190℃ showed a 61.5% reduction in overall mutagenicity. However, these data revealed no significant difference in mutagenicity in the ethanol, ethyl acetate, or water fractions. Formation of MeIQx (2-amino-3,8 dimethylimidazo[4,5-f]-quinoxalin) and PhIP (2-amino-1-methyl-6-phenylimidazo[4,5-b]-pyridine) was inhibited 60.7-63.5%. Cooked beef marinated with the water fraction of the N. nucifera leaf significantly (p
