[Chromatographic control of the process of rifamycin B isolation and purification].
A method of chromatography in a thin layer of Silica Cel No. 2 was developed for rifamicin B, rifamicin complex and some admixtures. Extracts of rifamicin B in an organic solvent, aqueous buffer reextracts and dry preparations of rifamicin B were analyzed with the above method. A half-quantitative chromatographic procedure for estimation of the main admixture in dry preparations was proposed.
