Abstract

A method for the determination of taurine and hypotaurine in biological samples involving the preparation of their 3,5-dinitrobenzoyl derivatives followed by HPLC was established. Taurine and hypotaurine in aqueous media were reacted with 3,5-dinitrobenzoyl chloride in the presence of triethylamine to prepare 3,5-dinitrobenzoyl derivatives. These derivatives were separated on a C18 reversed-phase column and detected by recording the absorbance at 254 nm. Derivatives of taurine and hypotaurine were obtained in yields of 91.4 +/- 3.3 and 85.6 +/- 2.6%, respectively. The calibration graphs for taurine and hypotaurine were linear between 2.5 and 500 microM with correlation coefficients of 0.999. The method was applied to the determination of taurine and hypotaurine in human and rat urine and blood and in rat liver and heart.
