Application for novel electrochemical screening of antioxidant potential and phytochemicals in Cornus mas extracts

ABSTRACT Cornelian cherry (Cornus mas L.), a fruit found in Central Europe, is used as a traditional ingredient in fruit preserves. In this study, we analyzed seven cultivars of Cornelian cherry growing in Poland and the differences between them in sugar content, total polyphenol content, and total chlorophyll content. Moreover, we measured the antioxidant potential of Cornelian cherry extracts was also measured. Polyphenols were found to be highest in S？owianin, Wydubieckij and Jolico cultivars. The presented research outcomes were extremely different from the results obtained for the other cultivars of Cornelian cherry. The electrochemical analysis of extracts proved that compounds contained in Cornelian cherry had the reducing against peroxyl radicals, which makes these extracts an important class of nutritional antioxidants. Our study showed that electrochemical assessment can replace the standard colorimetric tests in the evaluation of the antioxidant potential of analyzed compounds
