Abstract An improved analytical method for the determination of coumestrol in dried alfalfa and leaf protein concentrates is described. In this method, chlorophyll is removed from an alcohol extract prior to the paper chromatographic-fluorometric measurement of coumestrol. Ninety-eight per cent of the coumestrol added to alfalfa leaf protein concentrates is recovered by this method. This improved method gives replicate values with lower standard deviations and coefficients of variation than the literature method.

Development And Validation

Purpose: Analytical method development and validation for the quantitative determination of Prucalopride succinate in bulk and tablet formulation which plays major role in the development and manufacture of pharmaceuticals. Methods: In the present work a simple, rapid and reproducible UV-Visible Spectrophotometric method was developed and validated according to ICH guidelines. Results and Conclusions: The parameters linearity, specificity, precision, accuracy, and robustness were studied. The wavelength 243nm was selected for the estimation of drug using methanol as a solvent. The drug obeys Beer-lambert’s law over the concentration range 2-10μg/ml. The accuracy of the method was assessed by recovery studies and was found between 97.2- 98.3 %. The method was successfully applied for routine analysis of Prucalopride succinate in bulk and formulation.
