Flow-injection spectrophotometric determination of methyldopa in pharmaceutical formulations
(Elsevier B.V., 2005-07-15)
A flow-injection spectrophotometric procedure is proposed for methyldopa determination in pharmaceutical preparations. The determination is based on formation of a yellow product (measured at 410 nm) after complexation of ...
