ABSTRACT Given the above, the objective of this study was to evaluate the bromatological, mineral and bioactive compounds of blackberry grown in a subtropical region. Blackberries fruits (Rubus sp.), Grown in an orchard of Unioeste, Campus Marechal Cândido Rondon (Paraná, Brazil), were used. Immediately after harvest, the fruits were taken to the Food Technology Laboratory for chemical analysis and bioactive compounds. The fruit samples for the analysis of reducing, bromatological and mineral sugars were frozen and sent to private laboratories. Hybrids are more perishable than cultivars. There is variation in color among the cultivars and hybrids studied. Hybrids and cultivars of black mulberry have a high content of ascorbic acid and fibers, with emphasis on the cultivar Tupy (75.0 mg 100 mL-1 and 7.23, respectively). Higher pH is verified in the cultivars Tupy and Arapaho (3.22 and 3.24, respectively). The Arapaho cultivar has fewer acid fruits (0.25 g 100 g-1), SS/total acidity ratio (36.88) and reducing sugar content (8.28 g 100g-1). Blackberry fruits are a rich source of bioactive compounds, such as cv. Chickasaw obtaining a higher content of total phenolic compounds (1368.84 mg EAG100mL-1) and the Boysenberry hybrid a greater amount of anthocyanin (5.11mg Ci-3-Gly g -1). The Chickasaw cultivar has a higher lipid content (4.59). There is no difference in moisture content, dry biomass and fruit firmness.
