Description
(+)-Proanthocyanidin A2 is a polyphenol oxidase (PPO) substrates isolated from grape seeds (Vitis vinifera L). Proanthocyanidins represent one of the major groups of plant polyphenols. A2 could isolated from the acetone-water extract (7:3, v/v) of horse chestnut seed shells (Aesculus hyppocastanum), after extraction with ethyl acetate, by combined LH-20 chromatography and TLC on Silicagel 60 plates.
