Webb20 mars 2015 · Proanthocyanidins (condensed tannins) are oligomers or polymers of flavan-3-ol units that are widely distributed in plants kingdom, e.g., apple, blueberry, chocolate, grape, and bark of pine [ 1 – 5 ]. Based on the hydroxylation patterns of their constitutive units, proanthocyanidins can be divided into several classes.
