DETECTION BY FLUORESCENCE OF PEROXIDES AND CARBONYLS IN SAMPLES OF ARACHIDONIC ACID

Abstract

Products of lipid peroxidation were compared in two different grades of commercially‐obtained arachidonic acid. The less pure 90% sample was yellow in colour, had low reactivity with 2‐thiobarbituric acid and diene conjugation but high u.v. fluorescence, whereas the 99% pure sample, which was clear in colour, showed a reverse pattern of oxidation products. The significance of these findings is discussed. 1982 British Pharmacological Society
