Abstract

trans-Resveratrol is often considered as one of the quality standards of red wine, and the development of a sensitive and reliable method for monitoring the trans-resveratrol levels in red wine is an urgent requirement for the quality control. Here, a novel voltammetric approach was described for probing trans-resveratrol using a graphene-modified glassy carbon (GC) electrode. The proposed electrode was prepared by one-step electrodeposition of reduced graphene oxide (ERGO) at a GC electrode. Compared with the bare GC electrode, the introduced graphene film on the electrode surface dramatically improved the sensitivity of the sensor response due to the π-π interaction between the graphene and trans-resveratrol. The developed sensor exhibited low detection limit of 0.2 μM with wide linear range of 0.8–32 μM and high stability. For the analysis of trans-resveratrol in red wine, the high anti-interference ability and the good recoveries indicated the great potential for practical applications.

Highlights

Resveratrol (3,5,4󸀠-trihydroxystilbene), a member of the stilbene family of phenolic compounds, has been reported to have health benefits because it could provide antioxidative and carcinogenic protection, reduce platelet aggregation, and decrease the incidence of coronary heart disease [1]
Due to the important physiological role and the significance of trans-resveratrol level, several analytical methods including liquid chromatography [5,6,7,8,9,10,11], capillary electrophoresis [12,13,14,15], fluorescent assays [16, 17], spectroscopy technique [18, 19], and molecularly imprinted polymer [20, 21] have been reported for the analysis of trans-resveratrol
Illustrations of the preparation of the electrodeposition of reduced graphene oxide (ERGO)/glassy carbon (GC) electrode and the detection for trans-resveratrol were shown in Scheme 1

Summary

Introduction

Resveratrol (3,5,4󸀠-trihydroxystilbene), a member of the stilbene family of phenolic compounds, has been reported to have health benefits because it could provide antioxidative and carcinogenic protection, reduce platelet aggregation, and decrease the incidence of coronary heart disease [1]. The rapid, sensitive, and accurate determination of trans-resveratrol in red wine is very important for the improvement of manufacturing process, the control of storage condition, and the evaluation of nutrition value. Due to the important physiological role and the significance of trans-resveratrol level, several analytical methods including liquid chromatography [5,6,7,8,9,10,11], capillary electrophoresis [12,13,14,15], fluorescent assays [16, 17], spectroscopy technique [18, 19], and molecularly imprinted polymer [20, 21] have been reported for the analysis of trans-resveratrol.
