ABSTRACT:
Peroxidic substances in a sample, e.g. one or more peroxidic substances in fats and oils or in an organic material, lipoperoxides in a living sample, etc. can be determined, directly in a sample or after extracting the lipoperoxides from a living sample with a solvent, by contacting the peroxidic substances with an oxidizable color reagent in the presence of a metallic compound produced from a metal which is able to have two or more valences to produce color, and measuring degree of coloring colorimetrically.
