Abstract
The aim of this study is to evaluate the content of phenolics: the total
phenols (TP), flavonoids (TF), anthocyanins (TA), as well as the total
antioxidant capacity (TAC) in three sour cherry cultivars (Prunus cerasus L.)
introduced to the southeast Serbia climate conditions. Among the researched
sour cherries, ?Oblacinska? cultivar contained the highest amounts of all
groups of phenolics, followed by ?Cigancica? > ?Marela?. A significant
difference were observed in the phenolic content among different cultivars
and growing seasons (p<0.05), and the phenolic compounds were significantly
higher in the growing season 2009. The examined cultivars possess a high
antioxidant capacity, and all phenolics of highy correlation with TAC. The
following compounds were identified and quantified using HPLC-DAD: 4
anthocyanins, the most abundant of which was cyaniding-3-glucoside in
?Marela? and ?Oblacinska?, and cyanidin-3-glucosylrutinoside in ?Cigancica?,
and 4 hydroxycinnamic acids, the most abundant of which was neochlorogenic
acid in all sour cherry cultivars. The growing and ripening process on the
tree of sour cherry cv. Oblacinska was evaluated, also. The results showed
significant increases in total phenols during the ripening, the total
anthocyanins and total antioxidant capacity and 4 quantified anthocyanins,
however the neochlorogenic acid decreased during the ripening. The study
indicated that the growing and climate conditions in southeast Serbia are
convenient for introducing sour cherry cultivars.
