title: Determination of the absolute redox potential of Rutin: experimental and theoretical studies.
abstract: The conditional formal potential, E degrees', of Rutin has been studied by cyclic voltammetry using a Rutin film deposited at the multi-wall carbon nanotubes modified glassy carbon electrode (GCE) as the working electrode in different pH phosphate buffered solutions. The experimental standard redox potential, E degrees, of Rutin is obtained to be 0.88 V versus SHE (Standard Hydrogen Electrode). High-level ab initio calculations have been also performed on a chemical model of Rutin and the absolute reduction potential has been calculated. The theoretical standard reduction potential relative to SHE (0.83 V) is in relatively good agreement with experiment.
