  • Objective To establish a method of analysis for glycine and lysis hydrochloride in human coagulation factor Ⅷ by pre-column derivation HPLC. Methods The sample was derivatized with 2,4-dinitrofluorobenzene(DNFB). HPLC was performed on a C18 column with gradient elution. The mobile phase A was water, B was acetonitrile and C was 0.05 mol/L sodium acetate buffer containing 4 mmol/L trimethylamine. The flow rate was 1.0 ml/min and detection wavelength was 360nm. Result There was a linear range for glycine between 2.980 g/L~14.90 g/L (r=0.999 9) and lysis hydrochloride between 1.195 g/L~5.975 g/L (r=0.999 9). The average recovery rate of glycine and lysis hydrochloride was 99.1% and 98.2%. Conclusion The established method is accurate and can be used to determine the contents of glycine and lysis hydrochloride in human coagulation factor Ⅷ.
