Densitometric analysis of 2-arylpropionate derivatives in pharmaceutical preparations

This is the authors' abstract. We don't add key points for this paper.

A TLC-densitometric method has been established for identification and quantification of tiaprofenic acid, ketoprofen, naproxen, dexibuprofen, flurbiprofen, alminoprofen, and ibuprofen in selected pharmaceutical preparations. The separation was performed on TLC silica gel F 254 plates using two mobile phases. UV densitometry was performed at 225 and 270 nm. The method is of high sensitivity; limits of detection and quantitation range from 0.05 to 0.29 μg per band. For individual constituents recovery ranged from 98.71% to 102.65%.
