Procyanidin B2

Abstract

(+) catechin and (-) epicatechin form proanthocyanidins, including procyanidins. Procyanidins can be categorized into A-type and B-type, depending on the nature of the interflavan bonds. B-type procyanidins have a single interflavan bond. A-type procyanidins have not only one interflavan bond, but also a second interflavanoid bond. The most common B-type procyanidins are B1, B2, B3, and B4. Procyanidin B2 (CAS 29106-49-8) is an epicatechin-(4β→8)-epicatechin dimer. Cinnamon, cocoa, and apples contain procyanidin B2.

Recent research indicates that Procyanidin B2 (CAS 29106-49-8) is a protein kinase inhibitor, promoting hair epithelial cell growth and stimulating anagen induction. Furthermore, B2 demonstrates other bioactivities and, therefore, possesses the potential to treat a wide range of diseases, such as diabetes mellitus, atherosclerosis, and non-alcoholic fatty liver disease.
