Abstract: This paper describes a new method for fluorometric determination of Lysine(Lys) with ninhydrin. The quantum yield of reaction is 0.51. The 1Rand NMRspectra of product formed were determined. The mechanism of reactionwas discussed, preliminary,too. The other amino acid interference was discoussed.The method is simple and rapid. The Lysine in sample was determined withsatisfactory and precision.

Key words: Fluorescence reaction, Ninhydrin, Lysine
