Amino acids such as l
-valine, and l
-leucine are widely used in medical practice, as drugs for parenteral and per-os feeding, in cattle breeding, and in poultry raising. It is shown that planar chromatography can separate these essential amino acids from accompanying amino acids contained in the culture liquids used for their manufacture. A method is proposed for quantitative determination of the concentration of the compounds by densitometric analysis. The method can be effectively used to check the various stages of amino acid production.
