A method of simultaneous separation of rifampicins O, S and rifamicin derivates S, SV in a thin layer of silica gel KSK No. 2 impregnated with acetate buffer, pH 4.6 in a solvent system chlorophorm-methanol (100:5) was developed. The minimum detectable amount of the compounds studied was 1--2gamma, when the coloured zones were estimated visually.
