Rapid, sensitive spectrophotometric method for quantitative determination of sulfatides.
A rapid, sensitive spectrophotometric method for the analysis of sulfatides is described. The assay method is based upon the formation of a colored complex between the cationic dye azure A and (anionic) sulfolipids; the complex is extractable by a solution of chloroform-methanol 1:1. With the exception of some of the phospholipids, the reaction is specific for the sulfolipids. Cardiolipin was t...
متن کاملSensitive and rapid spectrophotometric methods for determination of anticancer drugs.
Sensitive, rapid, and simple spectrophotometric methods were developed for determination of the anticancer drugs vinblastine sulfate (VBS) and vincristine sulfate (VCS), which belong to the class of vinca alkaloids. The first method is based on the reaction of VBS and VCS with diazotized dapsone, forming yellow azo products with absorption maxima at 430 nm. The colored species obey Beer's law i...
متن کاملA Highly Sensitive Kinetic Spectrophotometric Method for the Determination of Ascorbic Acid in Pharmaceutical Samples
In this study, a new reaction system for quantitative determination of ascorbic acid was introduced. The developed method is based on inhibitory effect of ascorbic acid on the Orange G-bromate system. The change in absorbance was followed spectrophotometrically at 478 nm. The dependence of sensitivity on the reaction variables including reagents concentration, temperature and time was investiga...
متن کاملDevelopment and Validation of a Rapid Derivative Spectrophotometric Method for Determination of Tropicamide in Eye Drops
Tropicamide is an antimuscarinic agent used as eye drops for refractive examinations. The aim of this study was to develop a simple and suitable analytical method for determination of tropicamide in eye drops in the presence of excipients. A zero-crossing third and fourth derivative spectrophotometric method was described for determination of tropicamide in eye drops. The measurements wer...
