Procyanidin B2 Procyanidin B2 Procyanidin B2 is a B type proanthocyanidin. Its structure is (−)-Epicatechin-(4β→8)-(−)-epicatechin. Procyanidin B2 can be found in "Cinchona pubescens" (Chinchona, in the rind, bark and cortex), in "Cinnamomum verum" (Ceylon cinnamon, in the rind, bark and cortex), in "Crataegus monogyna" (Common hawthorn, in the flower and blossom), in "Uncaria guianensis" (Cat's claw, in the root), in "Vitis vinifera" (Common grape vine, in the leaf), in "Litchi chinensis" (litchi, in the pericarp), in the apple, and in "Ecdysanthera utilis". Procyanidin B2 can be converted into procyanidin A2 by radical oxidation using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals under neutral conditions. Procyanidin B2
