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), andanthocyanin (20.31 ㎎/g) contents compared to the other berries. It also showed the strongest scavenging activities such asDPPH (69.69 ㎎ vitamin C/g) and ABTS radical scavenging activity (757.79 μmol trolox/g). Aronia G exhibited strong ferricreducing antioxidant power (553.98 μmol vitamin C/g), and oxygen radical absorbance capacity (820.92 μmol trolox/g). Inaddition, black currant and Aronia showed stronger inhibition of nitric oxide production in lipopolysaccharide-stimulatedRAW 264.7 cell than the other berries. According to the above results, the Aronia and other edible berries have notably highlevel of antioxidant activities and they could be used as a potential source of natural antioxidants.
