A novel, simple and economic reverse phase high performance liquid chromatography (RP-HPLC) method has been developed for the estimation of Vildagliptin in bulk and tablet dosage form with greater precision and accuracy. Separation was achieved on C18 column (250X4.6mm i.d.,5μm) in isocratic mode using Buffer :Acetonitrile in the ratio of 50:50(v/v) as(More)
