Validated microbiological and HPLC methods for the determination of moxifloxacin in pharmaceutical preparations and human plasma BJM
Abdelaziz,Ahmed A.; Elbanna,Tarek E.; Gamaleldeen,Noha M..
The article presents a comparison between microbiological and high performance liquid chromatographic (HPLC) assays for quantification of moxifloxacin in tablets, ophthalmic solutions and human plasma. The microbiological method employed a cylinder-plate agar diffusion assay using a strain of Esherichia coli ATCC 25922 as the test organism and phosphate buffer (pH8) as the diluent. The calibration curves were linear (R²&gt; 0.98) over a concentration range of 0.125 to 16 µgml-1. The within day and between days precisions were < 4.47% and < 6.39% respectively. Recovery values were between 89.4 and 110.2%. The HPLC assay used Hypersil® BDS C18 reversed phase column (250×4.6 mm, 5µm) with a mobile phase comprising 20 mM ammonium dihydrogen...
