Mexidol (3-hydroxy-6-methyl-2-ethylpyridine succinate) is a drug that exhibits neuroprotective, antihypoxic, anti-ischemic, nootropic, anti-stress and geroprotective effects can suppress or slow down oxidation reactions. Оbjective: to develop selective simple method for assessing the content of mexidol in tablets. Materials methods. The objects study were tablets 0.125 g. Derivative spectrophot...

The Derivative Spectrophotometry usually improves resolution bands, eliminates the influence of background and provides more defined fingerprints than original spectra, hence enhancing the detectability of minor spectral features. In this work, different madder types were collected and applied for dyeing woolen yarns used in Persian carpet in conventional pre-mordanting and dyeing process with ...

Platinum and ruthenium can be simultaneously extracted from hydrochloric acid solution by high molecular weight amines (trioctylamine (TOA) or diantipyrylmethane (DAM) in 1,2-dichloroethane) after preliminary conversion into the complexes with SnCl3 ligands. The determination of both metals in the presence of each other in organic solutions of the formed ion-pairs can be accomplished by applyin...

The significant spectral overlap (Di) 0.5 = 0.5667 which is about 75.3% overlapping of the UV/Visible absorption spectra of iron (II) and copper (II) complexes necessitates chemometric assisted methods for simultaneous analysis of these ions in the pharmaceutical mixture. These metal ions were analyzed simultaneously by UV/Visible spectrophotometric method where 8-hydroxyquinoline was used as a...

PURPOSE This study was designed to develop and validate two simple, rapid, and economical UV-spectrophotometric and the first-order derivative methods using the area under curve method for estimation of diacerein in bulk and in capsule formulation. MATERIALS AND METHODS In this study, hydrotrophic solution of 8 M urea and 0.5 M potassium citrate were employed as the solubilizing agent to solu...
