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

“…Different letters indicate significant difference (p<0.05).Depending on the mode of antioxidants action, there are two main methods for antioxidant activity evaluation, hydrogen atom transfer (HAT) and single electron transfer (SET). The HAT method includes ORAC (oxygen radical absorbance capacity) and TRAP (total radical-trapping antioxidant parameter) assay, while SET method includes DPPH, FRAP, ABTS/TEAC and CUPRAC assays(Bunea et al 2011;Litescu et al 2010;Tabart et al 2014). Significant differences between varieties of cultivated blueberries and harvesting time were obtained.…”

Commercial berry production is an attractive industry worldwide, including in Romania because berries are a rich source of bioactive compounds with antioxidant capacity, thus becoming the most important functional and nutraceutical foods in our diet. The aim of our work was to characterize two different species, Saskatoon berry (Amelanchier alnifolia Nutt., Rosaceae) and blueberry (Vaccinium corymbosum L., Ericaceae), from the point of view of total phenols and anthocyanin as well as of antioxidant capacity depending on their harvesting time. The analyzed cultivars ‘Ruben’ and ‘Duke’ were cultivated in the North-West of Romania, the first cultivar has been officially introduced in Romania in 2018. The results show that ‘Ruben’ cultivar is richer in bioactive compounds compared with ‘Duke’ cultivars. The level of total phenols of ‘Ruben’ cultivar was 297.937 ± 4.30 and 347.412 ± 14.13 mg GAE/100 g fw (fresh weight) at early and full ripening time, respectively. The highest anthocyanins content was found in ‘Ruben’ cultivar (410.659 ± 52.88 mg/100 g fw) at full ripening time. Also, the high values of antioxidant capacity determined by four different methods (DPPH, FRAP, ABTS, CUPRAC) was recorded in the case of cultivar ‘Ruben’. Both blueberry cultivars ‘Duke’ and ‘Ruben’ are rich sources in bioactive compounds such as phenolics, especially anthocyanins. The blueberries harvested at full ripening period provided the highest level of total phenols and anthocyanins compounds. These compounds act as powerful antioxidants and thus they could improve the health status of the human body, or can be used by food and nutraceutical manufacturers.
