Objective To explore the method for determining the content of free amino acid in transfer factor injection. Methods High performance liquid chromatography(HPLC) was adopted for the content determination. The method was as follows:chromatographic column:C18 Diamonsil(250.0 mm×4.6 mm,5μm);detection wavelength:360 nm;sample size:20μL;column temperature:(40 ±1)℃;flow velocity:1.0 mL/min;gradient elute;A mobile phase was 0.1% trifuoroacetic acid,and B mobile phase was 0.1%trifluoroacetic acid acetonitrile with 0.45μm filter membrane for filtration and degrassing;2,4-dinitrofluoroben-zene was undergone precolumn derivatization,gradient elution. Results Free amino acid area showed a good linear relationship (r2=0.9977,RSD=0.6%). Conclusion The HPLC for the content determination of free amino acid in transfer factor injection is simple,fast and accurate,and it is worthy of popularization and application.
