摘要: A method for the quantitative analysis of a 6-component mixture 2,3-bis-hydroxy- and 2,3-bisacetoxymethylquinoxaline corresponding mono- di-N-oxides has been developed. The consists paper chromatography in 3 solvent systems: formamide-benzene, formamide-chloroform, formamide-ether subsequent elution separated substances from spectrophotometric determination eluate concentrations.
