The present invention relates to a method in which dauno-mycin is eluted from a hydrophobic porous synthetic resin carrier onto which daunomycin is adsorbed from crude daunomycin with a buffered aqueous solution containing a water-miscible organic solvent to recover purified daunomycin. Daunomycin (daunorubicin) is purified efficiently.
L'invention a pour objet un procédé qui consiste à adsorber la daunomycine provenant de la daunomycine crue sur un support en résine synthétique hydrophobe poreuse, à éluer la daunomycine avec une solution tampon aqueuse qui contient un solvant organique miscible à l'eau, puis à récupérer la daunomycine purifiée. Ce procédé permet une purification efficace de la daunomycine (daunorubicine).
