Identification of adducts between oxidized rosmarinic acid and glutathione compounds by electrochemistry, liquid chromatography and mass spectrometry

2022-06-21 19:21:42 | الكلمات المفتاحية Oxidation Mechanism,

Natural polyphenols are omnipresent and are an integral part of the human diet as well as quinones. Glutathione (GSH) is present in a significant amount inside cells and consequently, GSH conjugates of polyphenols will be encountered in the body. In the current work, voltammetry and liquid chromatography–mass spectrometry were carried out to characterize the reaction mechanism of the electrochemical oxidation ... إقراء المزيد

Mechanistic Pathways and Identification of the Electrochemically Generated Oxidation Products of Flavonoid Eriodictyol in the Presence of Glutathione

2018-08-28 16:49:57 | الكلمات المفتاحية Cyclic voltammetry, Electrolysis, Oxidation Mechanism, Eriodictyol, Glutathione conjugates,

The metabolic oxidation pathways of dietary flavonoid eriodictyol (Er) are not very well-probed. In the present work, the electrochemical oxidation behavior of Er was studied in aqueous Britton-Robinson (B-R) buffer solution using cyclic voltammetry (CV), chronoamperometry (CA), and bulk-electrolysis (BE). The oxidation products and reaction pathways of Er in the absence and the presence of glutathione (GSH) were proposed and ... إقراء المزيد

Square wave voltammetric analysis of polyphenol content and antioxidant capacity of red wines using glassy carbon and disposable carbon nanotubes modified screen-printed electrodes

2018-08-28 17:02:47 | الكلمات المفتاحية Screen-printed electrode, Polyphenols, Antioxidant capacity, Red wines, Square wave voltammetry,

The polyphenols present in different French red wines were characterized electrochemically using square wave voltammetry (SWV). The voltammetric measurements were carried out using a glassy carbon electrode and disposable screen-printed carbon electrodes unmodified and modified with single- and multi-walled carbon nanotubes. The single-walled carbon nanotubes-modified screen-printed carbon electrode (SWCNTs-SPCE) showed the best results for the voltammetric analysis of polyphenols in ... إقراء المزيد

Electrochemical Determination of the Antioxidant Activity in Echinacea Purpurea Roots Using Square Wave Voltammetry

2018-08-29 07:18:46 | الكلمات المفتاحية Voltammetry, Caffeic acid derivatives, Antioxidant activity, Liquid chromatography, Echinacea purpurea herbs,

A simple and rapid electrochemical method was established to quantify the total polyphenol (TP) content and assess their antioxidant activity (AA) in roots of three _Echinacea purpurea_ (_E. purpurea_) species using square wave voltammetry (SWV). Individual polyphenol components were identified, and then quantified by ultra‐high performance liquid chromatography coupled with mass spectrometery (UPLC‐MS). Two major polyphenols, chicoric (ChA) and caftaric ... إقراء المزيد

Mechanism of Chicoric Acid Electrochemical Oxidation and Identification of Oxidation Products by Liquid Chromatography and Mass Spectrometry

2018-08-29 07:26:51 | الكلمات المفتاحية Chicoric acid, Glutathione conjugates, Oxidation Mechanism, Electrolysis, Cyclic voltammetry,

Electrochemical oxidation of chicoric acid (ChA) was investigated using cyclic voltammetry and chronoamperometry at a glassy carbon electrode. Chicoric acid generates single quasi‐reversible redox wave in cyclic voltammetry over a wide pH range, and an ECEC‐dimerization mechanism is proposed. Effect of glutathione (GSH) on the electrochemical oxidation of chicoric acid (ChA) was investigated in Britton−Robinson buffer solution. Ultra‐high performance liquid ... إقراء المزيد
