[Thin layer chromatography for the analysis of certain anti-inflammatory medicines].

This work was devoted to the elucidation of conditions for isolation of ketorolac and diclofenac from biological fluids. A method is proposed for the extraction of these compounds from solutions with organic solvents at different pH values. Other methods permit to optimize identification of analytes by thin layer chromatography while the densitometric technique may be used for qualitative and quantitative analysis of their composition in biological fluids.
