Résumé

Naringenin (NR) displays strong antioxidant and numerous pharmacological activities, mitigating severity of metabolic‐syndromes without undesirable side‐effects. With the upsurge of interest in administering NR as diet‐supplement antioxidant, in this work for the first time we implemented functionalized‐MWCNT/Nileblue‐composite on carbon paste electrode (fMWNCT/NB/MCPE), as electrochemical sensor for catalytic NR oxidation. Integrated properties of fMWCNT/NB and their consonance with CPE, led to lowering of Rct value with fast‐kinetics and diminution of over‐potential. NR determination was due to electrical‐conductivity, π‐π and electrostatic‐forces that magnified anodic current by 5.5 fold. In the pH range 3.0 to 10.0 NR undergoes irreversible oxidation via transfer of 1e−/H+. Critical parameters, namely, pH and scan rate were assessed to reinforce differential pulse voltammtery (DPV) sensitivity for quantitative measurements. Sensor's selectivity, stability, accuracy and reproducibility were determined. Finally its viability in quantifying NR was validated by scrutinizing NR fortified fruit juices, as real sample matrices.
