Description
  • The aim of this work was to test the polyphenols on carboxymethyl cellulose, which served as their carrier. The aqueous extract of blue marc vine variety Fratava was used as a source of polyphenols. These substances (in particular anthocyanins and tannins) have significant biochemical effects, including antioxidant ones able to destroy free radicals. There were examined changes occurring in this complex of polyphenols after exposure to UV radiation. Polyphenols content was measured before and after exposure to UV radiation and simultaneously determined changes in their antioxidant effect. It was found out that despite the very low light stability of coloured anthocyanins, the high content of total polyphenols was maintained even after 24 hour exposure to UV radiation and especially there was no significant change in their ability to quench free radicals
