Abstract: Sweet cherries (Prunus avium L.) contain various
phenolic compounds which contribute to total antioxidant activity.
Total polyphenols, tannins, flavonoids and anthocyanins, and
antioxidant capacity in a fruits of a number of selected sweet cherry
genotypes were investigated. Total polyphenols content ranged from
4.12 to 8.34 mg gallic acid equivantents/g dry fruit weight and total
tannins content ranged from 0.19 to 1.95 mg gallic acid equivalent/g
dry fruit weight. Total flavonoids were within the range 0.42-1.56 mg
of rutin equivalents/g dry fruit weight and total anthocyanins content
were between 0.35 and 0.69 mg cyanidin 3-glucoside equivalent/ g
dry fruit weight. Although sweet cherry fruits are a significant source
of different phenolic compounds, antioxidant activity of sweet
cherries is not related only with the total polyphenolics, flavonoids or
anthocyanins.
