Višnja maraska (Prunus cerasus var. Marasca) jedna je od najznačajnijih voćnih vrsta Dalmacije, još od 16 stoljeća od kada datira i proizvodnja poznatog likera Maraschino. Areal rasprostranjenosti maraske ograničen je uglavnom na dio područja sjeverne i srednje Dalmacije od Zadra do Makarske, gdje klima i tlo omogućuju postizanje visoke kvalitete ploda i specifične arome. Provedena istraživanja imala su za cilj utvrditi fizikalno-kemijske parametre (ukupnu suhu tvar, vodotopivu suhu tvar, ukupnu kiselost, udio mesa i koštica), ukupne polifenole i antocijane te antioksidativni kapacitet u plodu višnje maraske u dvije klimatski različite godine (2012 i 2013), na plantaži „Vlačine“ (Zadar). Značajno veće vrijednosti ukupne suhe tvari, ukupnih polifenola i antioksidativnog kapaciteta utvrđene su u 2012., dok su veće vrijednosti ukupnih kiselina i antocijana utvrđene u 2013. godini, što se može dovesti u svezu s većim količinama oborina i nižim temperaturama u fazi zriobe plodova u 2013. godini. Značajno niže vrijednosti antocijana u 2012. u odnosu na 2013. godinu mogu se objasniti ekstremno visokim temperaturama u fazi zriobe u 2012. godini, koje prema literaturnim navodima mogu smanjiti količinu antocijana i do 90 %. U obje godine istraživanja utvrđena je pozitivna korelacija između ukupnih polifenola i antocijana, što potvrđuje činjenicu da su antocijani dominantni polifenolni spojevi u plodu maraske.Sour cherry cv. Marasca (Prunus cerasus cv. Marasca) is one of the most important fruit species of Dalmatia ever since 16th century. Production of the famous liqueur Maraschino began at that time. The areal of the prevalence of marasca is limited mainly to the part of the north and central Dalmatia, from Zadar to Makarska, where the climate and soil allow the achievement of high fruit quality and specific aroma. The investigations were aimed to determine the physico-chemical parameters (total dry matter, water soluble dry matter, total acids and percentage of flesh and endocarp in fruit) and biologically active compounds (total polyphenols, anthocyanins and antioxidant capacity) of the marasca cherry fruit in the climatic two different years (2012 and 2013) on the „Vlačine” (Zadar) plantation. Significantly higher values of total dry matter, total polyphenols and antioxidant capacity were determined in 2012, while in 2013 higher values of total acids and anthocyanins were determined. That can be brought into connection with significantly higher amount of precipitation and lower temperatures in the phase of fruit ripening in 2013. In both years of investigation a positive correlation between the total polyphenols and anthocyanins was determine which confirms the fact that the anthocyanins are dominant polyphenolic compounds in the marasca fruit. Significantly lower values of anthocyanins in 2012. compared to 2013. can be explained by the extremely high temperatures in the stage of maturity in 2012. which, according to the literature, can reduce the amount of anthocyanins up to 90
