It has been found that in the colorimetric determination of kainic acid with ninhydrin, preliminary addition of benzene to the reaction system effects stabilization of the reaction and increased sensitivity of the coloration. The presence of over 2 molar volumes of amino acid or ammonium salts interferes with the determination but the presence of sugar and inorganic salts in the amount usually present in Digenea was found to be negligible.
