Peonidin antioxidant activity

The conq)arative antioxidant activities of extracts from the peels, solids and juice are shown in Table V. Table VI shows the con5>osition of different anthocyanins in cranberry. Cyanidin and peonidin were the principal anthocyanins present in all parts including juice each existed in two main glycosidic forms. Two glycosides of a third anthocyanin, petunidin, were found only in the peels which accoimted for about 14% of the total anthocyanin content in cranberry peels. 

Cyanidin, delphinidin, petunidin, peonidin, pelargonidin, and malvidin are the most common anthocyanins in nature [125]. Their antioxidant, antiinflammatory, and detoxification activities justify their preventive roles against cancer and cardiovascular diseases.
