Abstract
OBJECTIVE Norfloxacin capsules was determined by a improved HPLC method. METHODS The separation was performed on a spherisorb C18 column.The mobile phase was composed of phosphoric acid-triethylamin buf fer-water-acet onitrile(60:30:10).The eluate with a flow rate of 1.0ml·min-1 was detected at the wavelength of 278nm.RESULTS The calibration curves were good linear within the range of 4.8～96μg·ml-1(r=0.99998).The average recovery of norfloxacin was 98.5%,with RSD of 0.5%(n=5).CONCLUSION The improved method is rapid,good repeatabitity,accurate,reliable and suitable for determination of norfloxacin capsules.
