摘　　要：A rapid, accurate, and precise chiral Ultra fast liquid chromatography (UFLC) method was developed and validated for enantiomeric separation of racemic vildagliptin and <i>S</i>-vildagliptin according to the guidelines of the International Conference on Harmonization (ICH). The chiral chromatographic separation was achieved with a mobile phase consisting of 20 mM borax buffer (pH 9.0 ± 0.05), ACN, and 0.1% Triethylamine (50:50:0.1, v/v/v) at a flow rate of 1 ml/min using a chiralcel OD-RH column, tris(3,5-dimethyl phenyl carbamate) (250 mm × 4.6 mm, 5 μm) column. The UFLC analysis was monitored at 210 nm. The method showed good linearity with a regression coefficient (r²) of 0.999 in the range of 1 - 12 μg/ml for <i>S</i>-vilda. The detection limit (LOD), quantitation limit (LOQ), and the average percentage recovery for <i>S</i>-vilda were found to be 0.024, 0.075 μg/mL, and 99.19% to 100.4%, respectively. The percentages of relative standard deviation (% RSD) for intra- and inter-day precision were found to be 0.346% and 0.364%, respectively. The developed method proved to be reproducible as % RSD was <2% and it had robustness within the acceptable limit. The percentage purity of pharmaceutical preparations of <i>S</i>-vilda was found to be 99.19 w/w. The proposed chiral method can be put in application for the enantiomeric purity determination of <i>S</i>-vilda formulations.A rapid, accurate, and precise chiral Ultra fast liquid chromatography (UFLC) method was developed and validated for enantiomeric separation of racemic vildagliptin and <i>S</i>-vildagliptin according to the guidelines of the International Conference on Harmonization (ICH).
