Abstract: Objective:The aim of this study was to establish a LCMS/MS method for the detection of residual erythromycin in live attenuated varicella vaccine. Methods:Erythromycin was extracted from live attenuated varicella vaccine with acetonitrile as protein precipitator. The liquid phase separation was performed on Shiseido CAPCELL PAK C18 MG (150 mm×2.0 mm,5μm) column with 0.1% formic acid aqueous solution and 0.1% formic acid acetonitrile solution as mobile phase for gradient elution. The flow rate was 0.3 mL·min-1, and the sample size was 10 μL. Positive ion mode of electron spray ionization(ESI)and scanning mode of multiple reaction monitoring (MRM) were used for mass spectrometry detection.Results:The limit of detection (LOD) and limit of quantitation (LOQ) of erythromycin in live attenuated varicella vaccine respectively were 0.02 ng·mL-1 and 0.04 ng·mL-1,and the linear regression equation was Y=1.46×105X+1.12×104 (r=0.999 6) in the concentration range of 0.04-40 ng·mL-1. The intraday and daytime precision of the method were less than 5%, and the accuracy of that was in the range of 95%-115.1%. The recovery and matrix effect of the method were in the range of 96.5%-100.0% and -20%-20%, respectively.Conclusion:In this study, the LCMS/MS method that was used to detect residual erythromycin in live attenuated varicella vaccine have good specificity, high sensitivity and good reproducibility, which could be used for the detection of residual erythromycin in this vaccine.
