Abstract: The fruit-growing culture is widely represented throughout Serbia. Most often, raspberries are grown (for commercial purposes), but also blackberries and blueberries. In this study, the berry fruits (chokeberry, cherry, red currant, black currant, and raspberry) that are grown in the area of the Pšeter Plateau region were examined to determine the level of secondary metabolites. The total phenolics, flavonoids, tannins, and anthocyanins were evaluated. Fruit samples were taken at the time of full maturity. The highest concentration of all total phenols was recorded in chokeberry fruits (38.55 mg GA g-1 of extract). Chokeberry fruits also contain the highest concentration of anthocyanins (14.09 μg mL-1 of extracts). Blackcurrant fruits have the highest concentration of flavonoids (6.92 mg Ru g-1 of extract) and tannins (0.59 mg mL-1 of extract). Surprisingly low concentrations of phenols were recorded in the fruits of red and dark currants (0.71 and 3.75 mg GA g-1 of extract). The concentration of flavonoids is fairly uniform in all samples. The concentration of anthocyanin in the fruits of cherry, red currant, and raspberry has several times lower concentrations than chokeberry. The tannin concentration is uniform in the examined fruits and ranges from 0.062 mg mL-1 of extract (cherry) to 0.59 mg mL-1 of extract (blackcurrant). Our results show that cultivated berries from the Pešter Plateau have high concentrations of bioactive substances, which makes them recommendable for dietary use. This result can be related to the fact that this fruit grows in unspoiled environmental conditions.
