Separation of fuchsin analogs using thin layer chromatography.


The four analogs comprising basic fuchsin have been separated using thin layer chromatography (TLC). Mixtures spotted on reverse phase TLC plates were developed with a solution of 25% methanol, 10% ammonium hydroxide, and 65% distilled water. The Rf values of the analogs were for pararosaniline, 0.54; rosaniline, 0.41; magenta II, 0.31; new fuchsin, 0.19.
