High-performance thin-layer chromatographic determination of ketoconazole in pharmaceutical formulations
A high-performance thin-layer chromatographic method was developed for the determination of ketoconazole. The sample was separated on a silica gel 60 F254 plate and developed in ethanol-acetone-1.0 mol l-1H2SO4by means of an automatic multiple-development system. The area of the spot was quantified...
