title: [Gas chromatographic analysis of amino acids in food].
abstract: 1. The methylester derivative of DNP-amino acid was examined by gas-chromatography and amino acid shown in fig. 1 was detected. 2. The gaschromatography was more sensitive than the ion-exchange chromatography, but detectable peaks were few, and it must be further studied. 3. The measurements of five amino acids in food were almost coincident with those obtained by the ion-exchange method in literatures.
