Proanthocyanidin - Wikipedia
Proanthocyanidins are a class of polyphenols found in many plants, such as cranberry, blueberry, and grape seeds. Chemically, they are oligomeric flavonoids . Many are oligomers of catechin and epicatechin and their gallic acid esters .
Proanthocyanidins - University of Rochester Medical Center
Proanthocyanidins are chemical compounds. They give the fruit or flowers of many plants their red, blue, or purple colors. They were first studied for their importance as plant pigments. These compounds have anti-inflammatory properties and may help prevent cancer.
