Procyanidin A1 is an A type proanthocyanidin dimer.
It is an epicatechin-(2β→7,4β→8)-catechin dimer found in Rhododendron spiciferum , [1] in peanut skins [2] and in Ecdysanthera utilis . [3]
Procyanidin B1 can be converted into procyanidin A1 by radical oxidation using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals under neutral conditions. [4]
