Objective To establish an HPLC method for content determination of antiseptic in iron proteinsuccinylate oral solution. Methods HPLC with AichromBond-AQ C18 column was adopted.The mobile phase was acetonitrile-water (40∶60)at the flow rate of 1.0 mL·min -1 ,and the detective wavelength was 254 nm.The column temperature was 40℃.Results Sodium methylparaben and sodium propyl p-hydroxybenzoate isolated completely.The calibration curves were linear in the range from 0.873 mg·L -1 to 8.732 mg ·L -1 and from 0.296 mg·L -1 to 2.964 mg·L -1 (r >0.999).The average recoveries were 99.1% and 100.1% (RSD <2.0%). RSDs of precision were 0.04% and 0.22% respectively.Conclusions The method is convenient and rapid,which can be used for ac-curate and reliable quantitative detection of antiseptic in iron proteinsuccinylate oral solution.
