Resumo: The cherry is a fruit with high nutritional value that has phenolic compounds in its constitution, mainly phenolic acids and anthocyanins, and a great antioxidant activity. The aim of the present work is a comparative study of physical and chemical parameters between sweet and sour cherries, namely in: size and weight, color, total content in phenolics and flavonoids, anthocyanins, and antioxidant activity. Overall results showed differences in physical and chemical parameters analyzed between the sweet and sour cherries obtained by breeding program or obtained by local landraces from more or less remote source. The results of antioxidant activity, total phenolics and anthocyanins were higher when compared to the literature. Sour cherries reveled to be smaller, with less weight, higher antioxidant activity and higher content of phenolic compounds. The anthocyanin levels on the varieties studied differed between sweet and sour cherries, as well as among the cultivars within each group.
