Abstract:
Rapid, simple and accurate chromatographic (HPLC) method for the determination of trandolapril was elaborated. Samples were chromatographed on a LiChrosorb RP-18 column and the mobile phase was acetonitrile -0.067 M phosphate buffer pH 2.7 (7:3, v/v). The UV detection at 220 nm and benazepril as an internal standard were used. The method was tested for linearity (over the range 4-20 micrograms.ml-1), precision and accuracy and was successfully applied for the quantitative determination of trandolapril in capsules.
