Voltammetric Determination of Ferulic Acid Using Polypyrrole-Multiwalled Carbon Nanotubes Modified Electrode with Sample Application
A polypyrrole-multiwalled carbon nanotubes modified glassy carbon electrode-based sensor was devised for determination of ferulic acid (FA). The fabricated sensor was prepared electrochemically using cyclic voltammetry (CV) and characterized using CV and scanning electron microscope (SEM). The electrode shows an excellent electrochemical catalytic activity towards FA oxidation. Under optimal conditions, the anodic peak current correlates linearly to the FA concentration ... Read more

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