Abstract:
OBJECTIVE:To establish HPLC method for the content determination of bacteriostatic agent benzyl alcohol in Clindamycin phosphate injection.METHODS:The determination was performed on CAPCELL PAK C8 column using potassium dihydrogen phosphate solution-acetonitrile(775:225)as mobile phase at flow rate of 1.0 mL?min-1.The detection wavelength was set at 210 nm.RESULT:The linear range of benzyl alcohol was 4.175～41.75 ?g?mL-1(r=0.999 9)with an average recovery of 100.5%(n=9),RSD=0.09%.CONCLUSION:The method is accurate and reproducible for the content determination of benzyl alcohol in Clindamycin phosphate injection.
