Changes in the antioxidant activity of polyphenols from grape pomace after interaction with UV radiation

Popis výsledku v původním jazyce

The aim of the study was to determine changes in the content of polyphenols and their antioxidant activity after interaction with UV radiation. An aqueous extract of grape pomace was used as a source of the tested polyphenols. Due to the differences between coloured monomeric anthocyanins and polymeric condensed tannins there were tested extracts from the skins and seeds separately. It was shown that despite the light instability of coloured anthocyanins a high content of total polyphenols remained in these solutions, and also their ability to destroy free radicals remained high even after 24 hours of exposure to UV radiation.
