| Abstract: | Taurine in RedBull Super Vitamin Drinks was determined by OPA pre-column derivatization and High Performance Liquid Chromatography(HPLC),using C_(18) column as fixed phase,methyl alcohol+0.05mol/L NaAc as mobile phase(45+55 by volume),with wavelength 330nm.The separation effect is satisfactory;derivatization reaction is rapid;the linear correlation coefficients of peak areas and concentration is 0.9999 in the range of 10~50g/ml respectively;the recoveries of the Taurine were 97.48%~101.0%,RSD were 2.5%.This method is accurate and suitable for quality control of Tongluoxiaru Koufuye. |
