Procyanidin B5
CAS: 12798-57-1
CAT: 4994
Abstract
Procyanidins are proanthocyanidins formed from (+) catechin and (-) epicatechin. 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 four most common B- type procyanidin dimers are B1, B2, B3, and B4, which contain C4→C8 interflavan linkages. B-type procyanidin dimers B5, B6, B7, and B8 contain C4→C6 interflavan linkages. Procyanidin B5 (CAS 12798-57-1) is an epicatechin-(4β→6)-epicatechin dimer. It is commonly isolated from cocoa, apple, and grapeseed.
Research indicates that intake of Procyanidin B5 provides advantages on human metabolism, circulation, and the nervous system.
