Abstract

A simple, rapid and sensitive high-performance liquid chromatographic (HPLC) method was developed for the assay of enrofloxacin in raw material and injection. The validation method yielded good results and included the range, linearity, precision, accuracy, specificity, recovery, limit of detection (LOD) and limit quantification (LOQ) values. The HPLC separation was carried out by reversed phase chromatography on a C-18 absorbosphere column (150 x 4.6 mm i.d. 5 microm particle size) with a phase composed of sodium acetate (pH 4.7; 0.1 M): acetonitrile (60:40, v/v; pH 5.0), pumped isocratically at a flow rate of 1.5 ml min(-1). The effluent was monitored at 278 nm with the eluting solvent. The calibration graph for enrofloxacin was linear from 10.0 to 80.0 microg ml(-1).
