Abstract The finding of melatonin, the often called “hormone darkness” in plants opens an interesting perspective associated to plethora health benefits related moderate consumption red wine. In this study, implementation a new method for determination melatonin complex food matrices by CEC with immobilized carboxylic multi‐walled carbon nanotubes as stationary phase is demonstrated. results indicated high electrochromatographic resolution, good capillary efficiencies and improved...
Abstract Propranolol is currently considered as an emerging contaminant in water bodies. In this study, R ‐ and S ‐propranolol were determined river samples by electrokinetic chromatography (EKC) using nanodiamonds (NDs) human serum albumin (HSA) a pseudo‐stationary phase order to achieve enantioseparation. Previously, preconcentrated column filled with Amberlite® IR‐120 Dowex® 50WX8 resins. The setting up of influential factors such temperature, voltage, pH, HSA NDs concentration accurately...
Abstract About two‐thirds of the world's population is infected with Helicobacter pylori ( H. ). This Gram‐negative bacterium most important etiological agent chronic active type B gastritis and peptic ulcer diseases. Conventional methods such as gastric biopsy, ELISA culture, require a long time for determination infections. Moreover, antibodies in human serum sample are capable to react immunologically purified antigens immobilized on different kinds support like magnetic nanobeads. In...
Abstract The separation methods of the enantiomers two β‐blockers and tryptophan were studied using capillary electrochromatography with heparin covalently as well non‐covalently, bonded onto inner wall stationary phase electrokinetic chromatography pseudostationary phase. In case heparin, used a phase, method was unable to resolve in both cases tryptophan. On other hand, when resolution obtained only 3‐aminopropyltriethoxysilane which immobilised capillary. results this study let us infer...
In this paper we propose two different electrochemical methods such as Cyclic Voltammetry (CV) and Osteryoung Square Wave (OSWV) to study the free radical scavenging ability of Selenium (Se) natural synthetic antioxidants. The originality is based on synergic effect Se, not only with α-Tocopherol, but a variety As result, find an important synergism, in vitro, between Se some other antioxidants aqueous medium.
Abstract Introduction – Larrea divaricata Cav. is a common shrub used in folk medicine to treat variety of diseases. The main product extracted from this bush nordihydroguaiaretic acid (NDG), which potent antioxidant. Objective In paper we propose novel method for the quantification NDG different extracts . concentration two aqueous (I and D) an ethanolic extract (Eet) was analysed, order evaluate safe use pharmacological purposes. Methodology Micellar electrokinetic chromatography (MEKC)...
We discuss the separation and determination of cadmium copper in plant samples such as Triticum durum (wheat) Helianthus annuus (sunflower) using open tubular capillary electrochromatography with indirect detection. Before performing analysis, were digested by microwave-assisted methods HNO3 . Regarding electrophoretic system, several experimental parameters previously evaluated surface, mobile phase composition, buffer, pH, voltage applied. The baseline resolution studied metals was...
