Objective:To establish an HPLC method for the determination of benzalkonium bromide in chloramphenicol eye drops .Methods:Phenyl silane bonded silica gel was adopted as stationary phase with a mixture of 0.05 moL· L-1 potassium dihydrogenphos-phate solution (triethylamine adjusted pH to 5.5 ) and acetonitrile (40∶60) as mobile phase at the flow rate 1.2 mL· min-1.The de-tecting wavelength was set at 220 nm, the column temperature was 40 ℃and the injection volume was 20 μL.Results:A good linear relationship of benzalkonium bromide was achieved in the range of 0.0304-1.218 μg( r=0.9998 ) ,limit of detection was 3.45 ng and limit of quantitation was 6.9 ng.The average recovery was 99.8%(n=9),RSD=1.5%.Conciusion:The method is accurate, relia-ble and could be used to control the quality of benzalkonium bromide in chloramphenicol eye drops effectively .
