Thin-layer chromatography of phenyl thiohydantoin derivatives of amino acids on silica gel thin layers impregnated with zinc salts and some metal sulphates

Abstract

Thin-layer chromatography of fifteen-component mixtures of phenyl thiohydantoin derivatives of amino acids was carried out on silica gel plates impregnated with various Zn salts (chloride, sulphate, phosphate and acetate) and sulphates of Mg, Mn, Fe and Co, and three solvent systems were developed. The effect of various anions and cations on the chromatographic behaviour is discussed.
