A PROCESS FOR THE ISOLATION OF PHARMACOLOGICALLY ACTIVE PRINCIPLES OF VEGETABLE AND ANIMAL ORIGIN

摘要

A process for the recovery and purification of natural hydrophilic water-soluble products in conjugated form from vegetable aqueous extracts or physiological fluids, by adsorption of said extracts or fluids on a lipophilic resin, followed by desorption and recovery of the eluate, which process is characterized in that the resin is a porous styrene-divinyl benzene polymer brominated at the styrene and/or divinylbenzene portion, with 600 m²/g area, 1.3 ml/g volume (dry weight), about 200 Angstrom pore size.
