Antioxidant effect compared to other berries (Zheng and Wang 2003)
This study compared the antioxidant activity of blueberries, cranberries, cowberries and chokeberries. It established that aronia has a much higher antioxidant effect than the other berries. This can be explained by the fact that its total phenol and anthocyanin content is also higher than in the other berries.
The phenolic acids contained in aronia are mainly caffeic acid and its derivatives, which have a very high antioxidant activity (caffeic acid: 20.6%; derivatives: 17.6%). It also contains cyanidin-3-arabinosides (18.4%) and cyanidin-3-galactosides (28.5%), which also have a very high antioxidant activity compared to the overall antioxidant activity of the aronia berry. Quercetin and cyanidin phenols also have a high rate of radical formation and can be found in all four berry types.
