Development and Validation of Rp-Uplc and Derivative Spectrophotometric Methods for Quantitative Determination of Ascorbic Acid and N-Acetylcysteine in Effervescent Tablets
Abstract:In this study, reverse phase-ultra performance liquid chromatographic (RP-UPLC) and first derivative spectrophotometric methods were developed and validated for the simultaneous determination of ascorbic acid (AA) and n-acetylcysteine (NAC) quantities in effervescent tablets. Liquid chromatography tests were carried out isocratically with the UPLC BEH C 18 column. Analyzes were completed in a short time (approximately 6 minutes) with the developed method. UV detector at 220 nm (detection wavelength) was used a… Show more
