Summary Preparative reversed-phase HPLC techniques for the separation of different hydrophilic fermentation products have been developed to shorten the comples and time-consuming isolation procedure. Separations were performed with low adsorptive reversed-phase packings and, additionally with strong acidic volatile modifiers to prevent adsorption, especially of the basic polypeptide antibotics epidermin and gallidermin on the stationary phases. The complex nature of the crude products required a particle size of 10 micron to separate the substances in a purity between 94% and 100%. The loading was limited to 100mg per injection on a 16 mm i.d. column, which corresponds to 4×10−3 g/g stationary phase.
