Abstract:
OBJECTIVE:To establish the method for determining the content of Lomefloxacin in hollow type suppository of Lomefloxacin hydrochloride.METHODS:RP-HPLC was used with Eclipse XDB-C 18 column(4.6mm?250mm)and the mobile phase consisting of citric acid(0.05mol/L)-acetonitrile(82∶18)the pH of which was adjusted to4.0with triethy?lamine.The flow rate was1.0ml/min and the detection wavelength was287nm.RESULTS:The average recovery of Lome?floxacin was99.8%and RSD was0.6%.CONCLUSION:The method is rapid and accurate and can be used for determination of the content of Lomefloxacin in hollow type suppository.
