    摘要: The invention relates to a process for obtaining procyanidol oligomers according to which: an appropriate plant is treated by means of an extractive mixture composed of water, of a water-miscible organic solvent capable of dissolving the procyanidol oligomers and of sodium chloride, the crude mixture of procyanidol oligomers obtained is purified by removal of the extractive mixture and extraction of the residue, the extractive mixture optionally being recycled in the stage of treatment of the plant, the procyanidol oligomers are recovered in a pure form by precipitation.
