Ziyatdinova G. Electropolymerized eugenol-MWNT-based electrode for voltammetric evaluation of wine antioxidant capacity / G. Ziyatdinova, E. Kozlova, H. Budnikov // Electroanalysis. - 2015. - V.27. - № 7. - P. 1660-1668. |
| Аннотация |
Eugenol electropolymerization conditions on multiwalled carbon nanotube based glassy carbon electrode (MWNT/GCE) have been found. The polyeugenol/MWNT/GCE shows reversible redox steps of o-quinone fragment in acidic media. Natural phenolic antioxidants are oxidized on polyeugenol/MWNT/GCE at 0.52 V excluding resveratrol (0.62 V). Differential pulse voltammetry on polyeugenol/MWNT/GCE was applied for the evaluation of wine antioxidant capacity (AOC). The AOC was expressed in catechin equivalents per 1 L of wine. The linear dynamic range is 1.00?250 mM with LOD and LOQ of 0.21 and 0.71 mM of catechin, respectively. Positive correlations for AOC with antioxidant activity (r=0.9840) and total phenolics content (r=0.9944) were observed. |
