Sushobhan Ukil, Titil Datta Samanta and S. Laskar*

A new reagent has been introduced for the detection of amino acids. This reagent is capable for easy identification of amino acids on thin-layer chromatography plates by developing various distinguishable colors (detection limit: 0.08-5 ?g). The colors thus obtained are more or less stable up to 6 -10 hrs.

Amino acids; TLC; 4- dimethylamino benzaldehyde; Isatin
