Abstract
Abstract Fluorescamine (FSA) has been widely applied for the determination of several classes of compounds containing amino groups. The estimated substances included pharmaceutical compounds, pesticides, amino acids, peptides and proteins. In addition, the activities of some enzymes were also monitored by FSA assay. The employed techniques mainly included spectrofluorimetry, as spray reagent in TLC, a derivativzation reagent in HPLC and capillary electrophoresis. Although there are many other reagents for detecting primary amino group containing compounds, FSA is advantageous as the reagent itself and its hydrolytic product are non-fluorescent. While other reagents such as NBD-Cl, dansyl chloride and o-phthaldehyde have a native fluorescence and their hydrolytic products are indeed fluorescent. In addition, the involved reaction is very fast and carried out at ambient temperature. However, the sensitivity of FSA analysis is much lower than these reagents. The sensitivity of the reagent could be enhanced by the proper selection of the diluting solvent, addition of surfactants or extraction with water immiscible solvent. The present article represents a comprehensive review for the application of FSA as a reagent in chemical and biochemical analysis since its discovery until now.
