Abstract

Wild berries, integral parts of North American Natives' traditional nutrition, are a rich source of phytochemicals involved in the prevention of metabolic syndrome. Although phenolic compounds are generally considered to be the functional components in fruits, the identification of specific compounds in relation to this beneficial activity remains to be uncovered. With the long-term goal of establishing the contribution of phytochemical compounds to their beneficial health effects, we investigated in a comprehensive manner the composition of twelve native Canadian berries: Saskatoon berry, alpine bearberry, chokeberry, black crowberry, honeysuckle, chokecherry, cloudberry, elderberry, lowbush blueberry, alpine blueberry, lingonberry and highbush cranberry. All harvested in the province of Quebec, these fruits were analyzed for their phenolic composition (anthocyanins, flavonols, flavan-3-ols, phenolic acids, proanthocyanidins and ellagitannins) and their content in abscisic acid derivatives (. cis- and trans-ABA, abscisic acid-glucose ester, 7'-hydroxy-abscisic acid, neo-phaseic acid, phaseic acid and dihydrophaseic acid). Over 60 different phenolic compounds were identified and quantified in berries. Along with the characterization of abscisic acid, this study reports for the first time a complete characterization of proanthocyanidins in these fruits, highbush cranberry presenting the highest content of this class of compounds. © 2015 Elsevier Inc.
