Extraction-chromatographic determination of glucose and fructose in the presence of aromatic amino acids

Бесплатный доступ

The extraction of glucose and fructose from aqueous salt solutions containing aromatic amino acids (phenylalanine, tryptophan, tyrosine), hydrophilic solvents (aliphatic alcohols, alkyl acetates, ketones) have been studied. The quantitative characteric of the process (the distribution coefficients, the degree of extraction, separation factors) are calculeted. The dependence of distribution ratios of monosaccharides from the amino acid content in the solution has been established. A mobile phase for analysis of the concentrate by ascending thin layer chromatography have been developed.
