A new, simple and accurate high-performance liquid chromatography method is
presented for measuring perindopril in tablets, using a reversed-phase tec
hnique, UV detection at 211 nm and quinapril as an internal standard. Linea
r detection response was obtained for the concentrations range from 0.1 to
0.5 mg ml(-1). The limit of detection was 50 mu g ml(-1). Perindopril was e
xtracted from tablets with methanol. The percentage of recovery ranged from
95.0 to 102.75%.
