<p>A METHOD FOR QUANTITATIVE ANALYSIS OF L-LYSINE IN PROTEINACEOUS TEST SUBSTANCES The specification discloses a method for quantitative analysis in which a test sample containing L- lysine in proteinaceous substances is reacted with a .gamma.-formyl-pyridine reagent of the general formula wherein R1 and R2 are each aliphatic carbon groups having not more than 4 carbon atoms or forming with two adjacent carbon atoms in the pyridine ring aromatic rings, in order to form the corresponding Schiff base, and the amount of reacted pyridine reagent is determined. In this way, the amount of L-lysine in the test substance can readily and accurately be determined.</p> |
