A validated HPTLC method for estimation of moxifloxacin hydrochloride in tablets
A simple HPTLC method having high accuracy, precision and reproducibility was developed for the routine estimation of moxifloxacin hydrochloride in the tablets available in market and was validated for various parameters according to ICH guidelines. moxifloxacin hydrochloride was estimated at 292 nm by densitometry using Silica gel 60 F254 as stationary phase and a premix of methylene chloride: methanol: strong ammonia solution and acetonitrile (10:10:5:10) as mobile phase. Method was found linear in a range of 9-54 nanograms with a correlation coefficient >0.99. The regression equation was: AUC = 65.57 x (Amount in nanograms) + 163 (r2 = 0.9908).
