Abstract

A procedure for the purification of an antibiotic consisting of contacting an aqueous solution containing FR-1923 substance, together with impurities, with a macroporous nonionic adsorption resin to adsorb the FR-1923 substance and elute the substance from the resin FR-1923 adsorbed with a hydrophilic solvent system or with an alkaline aqueous solution, or contacting an aqueous solution containing FR-1923 substance, together with impurities, with a macroporous non-ionic adsorption resin, previously saturated with FR- substance 1923, to adsorb impurities and recover FR-1923 substance from the past solution.
