Abstract:
A simple, highly sensitive, precise and accurate high-performance liquid chromatographic (HPLC) method was developed and validated for the determination of teneligliptin in rabbit plasma samples. The chromatographic separation was achieved with a reverse phase column thermo C18 (4.6×100 mm, 5µ) and the mobile phase consisted of methanol and 5mm potassium phosphate buffer (60:40 v/v) at a flow rate of 1mL/min. Sitagliptin was used as an internal standard. The retention time of Teneligliptin and sitagliptin were found to be 3.9and 2.2min respectively. The calibration curve was linear (r2 > or

Abstract:
The aim of this study was to develop a fast RP-HPLC method for simultaneous measurement of two antidiabetic formulations (vildagliptin + remogliflozin and teneligliptin + remogliflozin) under identical experimental conditions. Using the Box–Behnken approach and response surface design, the interaction and quadratic influence of three variable parameters, acetonitrile %, pH of the mobile phase, and flow rate, on resolution between the peaks were optimized. To forecast the resolution of peaks (2.7 and 6.5) for the three anti-diabetic medications, the design space with desirability function was u

Abstract:
A simple, precise, and accurate RP-HPLC method was developed and validated for the simultaneous estimation of TENE, PIO, and MET in pharmaceutical formulations as per ICH guidelines. The analytical wavelength utilized was 254.8 nm with linearity ranges of 1-6 μg/mL (TENE), 0.75-4.5 μg/mL (PIO), and 25-150 μg/mL (MET). Good linearity was demonstrated by the regression equations and correlation coefficients (r2 > 0.9985). Percentage recovery studies at 80%, 100%, and 120% levels showed mean recoveries within 99.5-102.3% (TENE), 99.4-102.2% (PIO), and 99.2-100.4% (MET) with relative standard d

Abstract An HPLC method with a fluorescence detector (HPLC-FLD) was described for the quantitative determination of closantel and rafoxanide in bovine and ovine muscles. A structural analog closely related to rafoxanide, viz., N-[4-(4-chlorophenoxy) phenyl]-2-hydroxy-3,5-diiodobenzamide, was synthesized as an internal standard.

Abstract We here report a reversed-phase HPLC method for the determination of free cortisol in human urine, using methylprednisolone as the internal standard. Before chromatography, samples were extracted with a C18 solid-phase extraction column and the steroids were separated on a LiChrospher 100 C18 column with a mobile phase of methanol/acetonitrile/water (43/3/54 by vol). Linearity, precision, and accuracy of the method were established. The detection limit was 10 pmol of cortisol, and total CVs were <8%. With various solid-phase extraction columns the recovery of cortisol was 36–97
