Abstract
|
|
|
Edible berries are rich in anthocyanins and phenolic acids, compounds that possess antioxidant, anti-inflammatory, and other biological activities. Antioxidant and anti-inflammatory activities of five berries including acaiberry (Euterpe oleracea Mart.), Aronia/black chokeberry (Aronia melanocarpa), blueberry (Vaccinium angustifolium), black currant (Ribes nigrum L.), and cranberry (Vaccinium macrocarpon) were assessed. The Aronia G (prepared by GreenField s.c.) exhibited the highest antioxidant activities as shown in total phenolic (138.81 ㎎ CAE/g), flavonoid (3.68 ㎎ QE/g), and anthocyanin (20.31 ㎎/g) contents compared to the other berries. It also showed the strongest scavenging activities such as DPPH (69.69 ㎎ vitamin C/g) and ABTS radical scavenging activity (757.79 μmol trolox/g). Aronia G exhibited strong ferric reducing antioxidant power (553.98 μmol vitamin C/g), and oxygen radical absorbance capacity (820.92 μmol trolox/g). In
addition, black currant and Aronia showed stronger inhibition of nitric oxide production in lipopolysaccharide-stimulated
RAW 264.7 cell than the other berries. According to the above results, the Aronia and other edible berries have notably high
level of antioxidant activities and they could be used as a potential source of natural antioxidants.
