Bioactive Compounds and Antioxidant Capacity of Several Blackberry (Rubus spp.) Fruits Cultivars Grown in Romania

Blackberry fruit (Rubus spp.) has a powerful antioxidant capacity due to the high levels of anthocyanins and other phenols it contains. In this work, we investigated physico-chemical characteristics, bioactive compounds (total phenols, flavonoids, monomeric anthocyanins), seven blackberry cultivars belonging Rubus fruticosus L. laciniatus genera growing in NW region Romania. addition, wild cultivar from same area was also evaluated. Anthocyanins were extracted using SPE (Solid Phase Extraction), anthocyanin profile identified quantified HPLC-PDA analysis. terms polyphenol content capacity, two examined stood out. The majority found blackberries cyanidin-3-glucoside, with highest amount recorded ‘Thorn Free’ at 329.26 ± 9.36 mg/g dw. Comparatively, ‘Loch Ness’ fruits exhibited total phenol contents 1830.98 13.55 1687.14 62.41 mg GAE/100 g dw, respectively. Antioxidant capacities varied significantly among eight cultivars, achieving values comparison others. findings multivariate analysis supported experimental results. Knowing phytochemical composition potential different blueberry one can use them as fresh, functional foods or for commercial purposes produce products derived concentration components.
