First derivative differential pulse polarography was developed and used for the quantitative analysis of chlorphenamine maleate, haloperidol, pyridoxine and their preparations. The method is simple, swift, sensitive and accurate.
The binding of chlorpheniramine to human serum albumin has been studied by fluorescence quenching, as a function of temperature; the experimental data could only be fitted to the Stern-Volmer modified equation. A statistical analysis of the results was performed in order to determine the significance of the constants calculated by this equation, as well as their thermodynamic parameters. The chlorpheniramine binding to human serum albumin accounts for almost half of the binding of this antihistaminic agent to human plasma proteins.
This paper provides the basic principle and experimental technique of differential--linear combination equal value derivative spectrophotometry. Quantitative analysis of three or four component--mixture can be done without separation. This method was investigated to assay the contents of chlorphenamine and propantheline bromide in Pukeling tablets by using UV-210A spectrophotometer. The average recoveries of chlorphenamine and propantheline bromide were 100.2 +/- 1.49% (CV) and 99.89 +/- 1.03% (CV) respectively. The results showed that it not only can effectively remove disturbances from each other, but also give higher sensitivity and accuracy.
