Abstract
Central composite design based RP-HPLC method optimization for the synchronized analysis of Efonidipine Hydrochloride Ethanolate (EFE) and Chlorthalidone (CHL) in tablet. The effective separation was performed using Inertsil ODS C18 column (250 × 4.6 mm, 5 μm), PDA detector with 0.05 M KH2PO4 Buffer (pH 4.5): Acetonitrile (40:60%v/v) mobile phase. Independent variables were investigated include the concentration of KH2PO4 (X1) and flow rate of mobile phase (X2). Based on responses obtained (retention time, resolution and tailing factor), the optimum condition selected was X1 = 40% and X2 = 1 ml/min. Optimized HPLC condition was validated by assessing validation parameters and it meets the acceptance criteria set by ICH. The linear calibration curve was found to be in the quantity range 6.25-18.75 and 20-60 μg/ml Assay of drugs was 100.94 and 100.06% for CHL and EFE. The validated RP-HPLC-PDA method can be used for routine analysis of EFE and CHL in tablet.
期刊介绍：
The Journal of Chromatographic Science is devoted to the dissemination of information concerning all methods of chromatographic analysis. The standard manuscript is a description of recent original research that covers any or all phases of a specific separation problem, principle, or method. Manuscripts which have a high degree of novelty and fundamental significance to the field of separation science are particularly encouraged. It is expected the authors will clearly state in the Introduction how their method compares in some markedly new and improved way to previous published related methods. Analytical performance characteristics of new methods including sensitivity, tested limits of detection or quantification, accuracy, precision, and specificity should be provided. Manuscripts which describe a straightforward extension of a known analytical method or an application to a previously analyzed and/or uncomplicated sample matrix will not normally be reviewed favorably. Manuscripts in which mass spectrometry is the dominant analytical method and chromatography is of marked secondary importance may be declined.
