The objective of this study was to evaluate the content of ellagic acid in blackberries, as well as in the juice of different blackberry cultivars obtained by using a specific technology. The analysis of the ellagic acid content in the test samples was performed using the high- pressure liquid chromatography with diode-array detection (HPLC-DAD). The results have shown considerable variations in ellagic acid content in the test blackberry fruit samples, the highest being determined in the fruit of the blackberry- raspberry hybrid cv. “Tayberry” (54.794 mg/100 g fresh weight), and the lowest in blackberry cv. “Čačanska Bestrna” (1.852 mg/100 g fresh weight). The ellagic acid content in the “Tayberry” juice produced using the specific technology was very high and almost identical to that in fruits.
