摘要

A process for recovering at least one Antibiotics S541 compound or chemical derivative thereof from solution in an organic solvent, which comprises the steps of contacting the said solution with alumina and adsorbing the compound(s) thereon, eluting the compound(s) and collecting the eluate containing the compound(s). This method is suitable for the large scale separation of individual S541 compounds or mixtures thereof.
