Abstract

The aim of this study was to examine the influence of climate conditions and ripening on total phenols
(TP), total monomeric anthocyanins (TAC) and antioxidant capacity (AC) of Maraska and Oblačinska
sour cherries. For that reason, TP using Folin-Ciocalteau reagent, TAC by pH-differential method and AC
via DPPH method were determined in Maraska and Oblačinska sour cherry samples harvested in Zadar
and Osijek area in 2014 at three maturity stages. Despite that statistical analysis showed significant
differences in TP and AC between cultivars and growing locations, obtained results revealed considerable
functional properties of both cultivars. Still, Maraska achieved higher TP, TAC and AC values compared to
Oblačinska. Furthermore, Mediterranean climate conditions positively affected on bioactive compounds
accumulation in both cultivars, where generally the highest contents of examined bioactive compounds
were accomplished at the latest harvest date.
