A simple reversed phase HPLC method have been successfully developed and validated for the quantitative determination of enalapril maleate (ENP) in bulk material, pharmaceutical formulation and serum. Purospher Start C 18 (250 cm x 4.6 mm, 5 μm) and Hypersil, ODS columns were used. The mobile phase, methanol-acetonitrile-water (70:30v/v pH 3.5 adjusted by phosphoric acid), was delivered at a flow rate of 1 mLmin -1 , eluent was monitored using UV detector at 215 nm. The proposed method is specific, accurate (99-102%), precise (intra-day and inter-day variation 0.07-1.25%) and linearity (R 2 >0.999) within the desired range 2.5-100 μgmL -1 concentration. The detection limit and quantification 3.9 ngmL -1 and 12 ngmL -1 respectively. The anticipated method is applicable to routine analysis of ENP in pharmaceutical formulations as well as in human serum samples.
