Spectrophotometric determination of atropine, pilocarpine and strychnine with chloranilic acid.
In dioxan-chloroform medium the acceptor chloranilic acid forms 1:1 molecular complexes with the alkaloids atropine, pilocarpine and strychnine, with maximum absorption at 535, 527.5 and 535 nm respectively. Conformity with Beer's law allows the use of the complexes for the assay of these drugs.
متن کاملSpectrophotometric Determination of Astemizole and Loratadine Based on Charge-Transfer Complex Formation with Chloranilic Acid
A simple and sensitive spectrophotometric method for the assay of two antihistamines, astemizole and loratadine, is described. The determination was based on the formation of chargetransfer complexes between chloranilic acid as a p acceptor and the studied drugs as n-donors in acetonitrile solvent. The spectra, various experimental parameters, composition and formation constant of the complexes...

The deteriorating quality of the environment and consequently stricter emission limits force the produc ers of pollutants to modernize their current technolo gies, to reduce technologies with toxic materials or to v minimalize emissions. The industrial use of formaldehyde in various fields such as textile, wood, leather, and food process ing industry causes a major environmental problem. For...
متن کاملThe Use of Chloranilic Acid for the Spectrophotometric Determination of Three Antihistamines∗
The three antihistaminic drugs investigated are of diverse chemical types, and many chemical methods have been reported for their assay. Cyproheptadine hydrochloride (CPH) is a serotonin and a histamine antagonist with anticholinergic and sedative effects. It also blocks voltage sensitive calcium channels in pancreatic islet cells and smooth muscle. CPH is also used as an appetite stimulant to ...
متن کاملSpecific photometric determination of 5-hydroxyindoleacetic acid in urine.
Udenfriend ‘s nitrosonaphthol test for 5-hydroxyindoleacetic acid (5-HIAA) is subject to interference by urinary phenolic acids and drug metabolites. Studies in our laboratory have shown that the specificity and sensitivity of the nitrosonaphthol reaction with 5-hydroxyindoles can be greatly enhanced by the addition of 2-mercaptoethanol. This observation serves as the basis of a simple, improve...
