The method involves heating an aqueous mixture of solid plant material, optionally under increased pressure and reduced oxygen; various separation, filtration and adsorption steps, and the elution of adsorbed proanthocyanidins with polar solvent. Optionally, the polar solvent can be reconstituted and recycled into the elution phase of the method, resulting in decreased solvent consumption.
