摘要

Process for extracting a dilute aqueous solution of kenamycin at an alkaline ph with a lower volume of a lower alcohol immiscible in water, characterized in that it contains per mole of kenamycin contained in said aqueous solution, from one to ten moles of a member selected from those of group consisting of the unsubstituted aliphatic aldehydes containing from four to ten carbon atoms inclusive, and the aromatic aldehydes, separating the alcohol phase and subsequently extracting the kanamycin contained in said alcoholic solution of kanamycin to an acidic ph in a smaller volume of one aqueous acid and separate the concentrated aqueous solution of kanamycin thus obtained.
