Abstract

Simple, accurate and reproducible UV spectrophotometric methods were established for the assay of buclizine BUCZ based on the formation of precipitation, charge transfer complex and inner complex formation. Method A involves the precipitation, charge transfer complex formation of BUCZ with tannic acid- p-N-methyl aminophenol sulphate PMAP-CrVI, the complex formation with cobalt thiocyanate CTC in method B and inner complex formation of BUCZ with sodium nitroprusside hydroxylamine hydrochloride and sodium carbonate in method C were proposed. The optical characteristics such as Beers law limits, molar absorptivity and Sandell’s sensitivity for the methods A-C are given. Regression analysis using the method of least squares was made to evaluate the slopeb, intercepta and correlation coefficient r and standard error of estimation Se for each system Determination of BUCZ in bulk form and in pharmaceutical formulations were also incorporated.
