Proanthocyanins

Proanthocyanins are a distinctive class of flavonoid, and was discovered in 1946 by a researcher from France who was doing studies on peanut skins, and its effect on circulation and heart disease.

The compounds known as proanthocyanins are polymers that are also known by a series of other names: flavolans, condensed tannins, polyflavonoid tannins, and proanthocyanidins are only a few examples.

Proanthocyanins, also known as flavolans, condensed tannins, and proanthocyanidins, are chemical compounds resulting from the condensation of flavans.
