Product Description

Procyanidin B2 is a B type proanthocyanidin. Its structure is-Epicatechin-epicatechin. Procyanidin B2 can be found in Cinchona pubescens, in Cinnamomum verum, in Crataegus monogyna, in Uncaria guianensis, in Vitis vinifera, in Litchi chinensis, in the apple, and in Ecdysanthera utilis.

Procyanidin B2 (PB2) is a naturally occurring flavonoid widely found in cocoa, red wine and grape juice. Recent studies have suggested that PB2 could protect against oxidative stress- and chemical-induced injury in colonic cells by modulating the endogenous cellular defence.
