![]() The content of taurine measured compared to the labeled amount in five commercial energy drinks containing taurine was 92.9-105.1%. Taurine is derivatized with fluorescein isothiocyanate at 100C in 20 min. Energy, was found by using high-performance liquid chromatography. Abstract In this work we describe a new method for taurine quantification in plasma by capillary electrophoresis laser-induced fluorescence detection. The recoveries were in the range of 98.2-99.9%, the precision as standard deviation was in the range of 0.3-0.5%, the linearity as a coefficient of correlation value was 0.999 and the specification was confirmed for taurine added to three commercial energy drinks. The concentration of taurine in two energy drinks, Monster Lo-Carb and 5-Hour. A mixture of disodium hydrogenphosphate-citric acid buffer solution (pH 5.4) containing 10 mmol/l tetrabutylammonium bromide and acetonitrile (7:3) was used as the mobile phase. There is very little information on the taurine content of ingredients used in home-prepared diets for dogs and cats, and foods fed to wild animals in captivity. The derivative was measured on a UV-Visible detector (470 nm) by HPLC using a conventional Octadecyl silane (ODS) column. The aim of this study was to determine the taurine content in a variety of animal feeds. The reaction of taurine with NBD-F finished in 10 min at 60☌. ![]() A rapid and simple method to determine taurine in energy drinks by pre-column high-performance liquid chromatography was developed using a derivative of 4-fluoro-7-nitrobenzofurazan (NBD-F) without the need for an exclusive instrument.
