A quantitative thin layer chromatography (TLC) and high performance thin layer chromatography (HPTLC densitometry) procedures have been developed for the determination of prophyphenazone and ketoprofen in formulations. These two constituents were separated by TLC techniques followed by extraction of the components with methanol and the measurements of their absorption in UV range. The HPTLC determination was performed by modifying the solvent system developed for TLC and then scanning the spots by densitometry.
