Abstract

Abstract The green analysis has acquired increased importance in different fields including pharmaceutical analysis. However, the majority of chromatographic methods still use large volumes of toxic and non- degradable organic solvents. This study displays a green HPLC assay method for simultaneous estimation of two moxifloxacin combinations: moxifloxacin/dexamethasone and moxifloxacin/prednisolone. Simultaneous separation of each of moxifloxacin binary mixtures was achieved on a reversed phase Thermo scientific MOS-1 Hypersil C8 column (250 mm × 4.6 mm i.d., 5-μm particle size) using an eco-friendly isocratic eluent; ethanol: water containing 0.05% triethanolamine (90:10, v/v, pH 4.5). The assay was completed for each combination within
