Some nitrofuran derivatives used for food and drug in Japan were separated by thin-layer chromotography on both silica gel and aluminum oxide. Ether-acetone (3 : 2) is used as the solvent system for silica gel plates and aceton for aluminum oxide plates. The spots were detected in ultraviolet light and with a color reagent of sodium hydroxide. The tables of Rf values and the minimum amount of the derivatives detected were given. The method serves as an accurate qualitative determination of the nitrofuran derivatives, either singly or in mixtures.
