[Comparative evaluation of antioxidant activity of phycocyanin and selenium enriched phycocyanin in vitro and ex vivo]

Abstract

Antioxidant properties of phycocyanin and selenium enriched phycocyanin were evaluated by using FRAP assay, inhibition of luminol oxidation in Hb - H2O2 system and inhibition of induced microsomal lipid peroxidation. In different model systems phycocyanin revealed antioxidant activity wich was comparable with antioxidant activity of bilirubin and Trolox. Inclusion of selenium into phycocyanin did not influence significantly its antioxidant properties.
