Electrochemical Characterization of Natural Antioxidants
Summary
The electrochemical characterisation of natural antioxidants encompasses a range of analytical techniques designed to probe the redox behaviour of plant-derived compounds that scavenge free radicals. Central to this field is the elucidation of relationships between molecular structure—particularly the number and arrangement of phenolic hydroxy groups—and electron-transfer properties. Techniques such as cyclic voltammetry, differential pulse voltammetry and amperometry provide insight into oxidation potentials, reaction kinetics and stability of intermediate species. Advances in electrode materials, including carbon-based substrates, nanocomposites and molecularly imprinted polymers, have enhanced sensitivity and selectivity, enabling real-time measurements in complex matrices such as food products, botanical extracts and biological fluids. These approaches underpin quality control in the food, pharmaceutical and cosmetic industries, inform nutraceutical development and offer routes to monitor bioavailability and therapeutic efficacy globally.

Electrochemical Characterization of Natural Antioxidants publication trend
The graph below shows the total number of articles in electrochemical characterization of natural antioxidants across all publications each year (not limited to Nature Index journals).
Technical terms
Cyclic voltammetry: An electrochemical technique in which the potential of a working electrode is swept linearly back and forth to record redox processes and determine oxidation and reduction potentials.
Differential pulse voltammetry: A voltammetric method that applies a series of potential pulses on a linear potential ramp, enhancing resolution and sensitivity for trace analysis.
Amperometric microsensor: A miniaturised electrochemical sensor that measures current at a fixed potential to quantify analytes in real time, often with nanomaterial-modified electrodes.
Redox potential: The voltage at which a substance undergoes oxidation or reduction; a lower oxidation potential indicates a greater tendency to donate electrons.
Flavonoid: A class of polyphenolic compounds with multiple hydroxyl groups on a flavan nucleus, widely distributed in plants and noted for antioxidant properties.
Phenolic compound: An organic molecule characterised by one or more hydroxy groups directly bonded to an aromatic ring, contributing to redox activity and free-radical scavenging.
