Determinationof antioxidantsbysensitizedchemiluminescence using 2,2¢-azo-bis(2-amidinopropane)

Abstract

For the determination of antioxidants, an analytical procedure was proposed based on chemiluminescence. The analytical system consists of a free-radicals generator 2,2¢-azo-bis(2-amidinopropane) and luminol as a chemiluminescence sensitizer in phosphate buffer solution (pH 7,4). The analytical conditions were optimized. The analytical procedure provides detection limits as low as (μM) for: trolox – 0,05; ascorbic acid – 0,20; quercetin – 0,03; dihydroquercetin – 0,03. The procedure was used for determination of antioxidants in food.
