The paper describes the invention of a simple, precise, and sensitive approach for detecting saxagliptin in bulk medication and marketed formulations using reverse-phase liquid chromatography. The separation was done on Epic C12 (250 mm×4.6 mm×5 µm) using mobile phase (Methanol: buffer) in the ratio of 80:20 (v/v). The run time was 7 minutes, and the wavelength for saxagliptin was taken as 230 nm. A literature review finds that there are very few HPLC techniques available using this composition of mobile phase. As a result, an attempt was undertaken to create an RP-HPLC technique for saxagliptin.
The devised method was validated in terms of accuracy, precision, linearity, system suitability, LOD and LOQ, robustness, and assay. The linearity ranged from 1-3 μg/ml, with a correlation value of 0.999. The designed and validated RP-HPLC method is used to identify the eluted.
