Abstract
Separation and identification of several kinds of barbituric acid derivatives by thin-layer chromatography were investigated. The thin-layer was made of a mixture of silicic acid, potato starch and sodium carbonate. The most suitable solvent system among those tested was ethylene dichloride-acetone (85 : 15). Spectroscopic characterization of the compounds submitted to the chromatography was performed by eluting the spots with 0.5 N ethanolic sodium hydroxide.
