title: Qualitative and quantitative characterization of mutagens in commercial beef extract.
abstract: Two mutagenic compounds have been isolated and purified from commercial beef extract. These two compounds have chemical, chromatographic, spectroscopic and biological behavior indistinguishable from those of the two known mutagens 2-amino-3-methyl-imidazo-[4,5-f]-quinoline and 2-amino-3,8-dimethyl-imidazo-[4,5-f]-quinoxaline.
