[Determination of sitagliptin phosphate in rat plasma by ultra high performance liquid chromatography-tandem mass spectrometry].

An ultra high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for the determination of sitagliptin phosphate in rat plasma was established. The blank rat plasma sample added with sitagliptin phosphate and the internal standard (fluoxetine) standard solution were prepared. Methanol was added in the sample for the… CONTINUE READING
