Abstract
Simple micellar electrokinetic chromatographic (MEKC) method was developed for the determination of ketoprofen as the active substance and methylparaben and propylparaben as preservatives in a semisolid pharmaceutical preparation. Separation was carried out with a fused silica capillary and UV detection at 200 nm. Optimized background electrolyte was 50 mM tricine buffer containing 30 mM sodium dodecyl sulfate as surfactant and 15% (v/v) of methanol. Single separation took about 13 min. No statistically significant differences were found when comparing the results with those of RP-HPLC method reported in literature.
