UPLC-PDA Approach for Simultaneous Quantification of Elvitegravir, Tenofovir, Emtricitabine and Cobicistat in Tablets: An MS-ESI Study for Degradation Products.
A simultaneous ultra-performance liquid chromatography photodiode array detection method was developed and validated for Elvitegravir, Tenofovir and Emtricitabine and Cobicistat drugs in tablet dosage forms. Effective liquid chromatographic quantification was achieved using a Luna C18 (100 × 2.6 mm, 1.6 μ) column with an acetonitrile: 0.1% v/v trifluoro acetic acid (80:20% v/v) mobile phase and a photo diode array detector at 260 nm for a shorter run time of 3 min. The respective retention times for Elvitegravir, Tenofovir, Emtricitabine and Cobicistat were 0.311, 0.792, 1.379 and 2.045 min. The range of linearity was 37.50-225.00, 2.50-15.00, 50.00-300.00 and 37.50-225.00 μg/mL for Elvitegravir, Tenofovir, Emtricitabine and Cobicistat, respectively. A mass spectrometer was employed for quantitative analysis using electron spray ionization multiple reaction monitoring in positive mode. The developed method was validated for different parameters to meet the acceptance criteria as per ICH Q2 (R1) guidelines. Using UPLC-ESI-MS, 12 degradants were identified and their mechanisms were studied.
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.
