Abstract:
In this work, we investigated the mineral profile, the bioactive compounds (phenols, flavonoids) content and the antioxidant
capacity of wild blueberries and their pharmaceutical preparations (tea, alcoholic extract and capsules). The highest content
of phenols and flavonoids was recorded in the alcoholic sample (813.42 ± 15.55 mg GAE- gallic acid equivalent/100 g and
1425.44 ± 1.94 mg QE- quercetin equivalent/100 g), and the highest antioxidant capacity was recorded in fresh blueberries
and in the tea derived from these fruits. The mineral elements composition analysis revealed high contents of manganese
(8.7956 mg/kg) in the fresh fruits and the antioxidant capacity was strongly linked to the phenols and flavonoid content, as to
the content of metals like Zn, Mn and Cu. Our results obtained in this study indicated that the pharmaceutical preparations
derived from blueberry have antioxidant potential and high concentrations of bioactive compounds.
