Determination of Quercetin and Luteolin in Paprika Samples by Voltammetry and Partial Least Squares Calibration

2017

Quercetin and luteolin are flavonoids with beneficious properties, which are present in paprika. In this work, both have been determined in paprika by using electrochemistry combined with chemometrics. The electrochemical oxidation mechanisms of both analytes have been studied through sampled direct current (DC) voltammetry, differential pulse voltammetry (DPV) and Square Wave Voltammetry (SWV), making use of a glassy carbon electrode. The final technique selected for the quantification was DPV due to its high repeatability with respect SWV. The chemical variables and the instrumental parameters were optimized and the final conditions employed were ethanol: water (20 : 80), 0.75 mol dm−3 of HCl, and a pulse amplitude of 50 mV. Due to the facts that oxidation potential of both analytes were quite similar, their DPV peaks were overlapped, and also because the analytes interaction during the electrochemical process causes a non‐additivity of the signals, they could not be quantified separately by direct measurement of peak intensity. For this reason, a chemometric algorithm was applied (partial least squares (PLS) regression in its modality PLS‐2). In the case of validation samples, appropriate sets of calibration and validation were built and good results were obtained. This methodology was applied to real paprika samples and the results were similar to those obtained with a HPLC method previously reported.

“…The electrochemical activity is thus adjusted to attain, for example, a higher sensitivity and selectivity, besides a lower adsorption . In some instances, BDDEs have been used without any electrochemical pretreatments in the determination of different analytes, with satisfactory analytical results and good repeatability, e. g . However, in most such cases, since comparisons with the electrochemical signals from the same BDDEs when electrochemically pretreated were not reported at all, the question of whether better results could be attained with a CPT‐BDDE or an APT‐BDDE remains unanswered.…”

“…The electrochemical activity is thus adjusted to attain, for example, a higher sensitivity and selectivity, besides a lower adsorption. [19,107,118,119] In some instances, BDDEs have been used without any electrochemical pretreatments [118][119][120][121][122][123][124][125][126][127][128][129][130][131][132][133][134][135][136] in the determination of different analytes, with satisfactory analytical results and good repeatability, e. g. [120,126] However, in most such cases, since comparisons with the electrochemical signals from the same BDDEs when electrochemically pretreated were not reported at all, the question of whether better results could be attained with a CPT-BDDE or an APT-BDDE remains unanswered. In a few of those cases, [133][134][135][136] when a free-standing BDD was used, the BDDE was simply polished, as first done by Marken et al; [77] comparisons between the electrochemical activities for the respective analyte after different pretreatments (polish, PTA or PTC) were performed in two cases, [135,136] with better results after the polish procedure.…”

Analytical Applications of Electrochemically Pretreated Boron‐Doped Diamond Electrodes

et al. 2020

View full text Add to dashboard Cite

The several outstanding properties of boron‐doped diamond electrodes (BDDEs) have allowed their application for various purposes, among them electrochemical sensing. However, the electrochemical response of many redox species on BDDEs can be strongly dependent on whether their surfaces are predominantly hydrogen‐ (HT) or oxygen‐terminated (OT). Fortuitously, electrochemical pretreatments themselves can be used to enrich in situ the BDEE surface in one or the other type of termination. The surface of a cathodically pretreated BBDE (CPT‐BDDE) becomes enriched in HTs, whereas that of an anodically pretreated BDDE (APT‐BDEE) becomes enriched in OTs. Thus, when suitable, the electrochemical activity of a BDDE for a given analyte may be tuned by electrochemical pretreatments, yielding enhanced sensing properties. The main purpose of this review is the compilation and discussion of papers published after 2009 reporting on electroanalytical applications based on a CPT‐BDDE or an APT‐BDDE. Procedures to perform proper electrochemical pretreatments are also discussed.

“…As result of microbial activities, BAs are often formed during the storage and processing of foods and an increasing biogenic amine level represents a decrease in food product hygienic quality. Therefore, the level of BAs in food can be used as an index for evaluating the quality of food, especially in perishable products . Consumption of food rich in BAs may cause adverse health effects with different symptoms .…”

Amperometric Biosensors for Tyramine Determination Based on Graphene Oxide and Polyvinylferrocene Modified Screen‐printed Electrodes

et al. 2019

View full text Add to dashboard Cite

A comparison of the analytical characteristics of two tyramine biosensors, based on graphene oxide (GRO) and polyvinylferrocene (PVF) modified screen‐printed carbon electrodes (SPCE), is reported. Diamine oxidase (DAOx) or monoamine oxidase (MAOx) was immobilized onto the PVF/GRO modified SPCE to fabricate the biosensors. Surface characteristics and electrochemical behaviour of the modified SPCEs were investigated by atomic force microscopy (AFM), scanning electron microscopy (SEM), energy dispersive X‐ray spectroscopy (EDX) and cyclic voltammetry (CV). Electrode surface composition and experimental variables such as pH and working potential were optimized in order to ensure a high performance. Under optimum experimental conditions, both DAOx/PVF/GRO/SPCE and MAOx/PVF/GRO/SPCE biosensors exhibited wide linear dynamic ranges for tyramine from 9.9×10−7 to 1.2×10−4 M and from 9.9×10−7 to 1.1×10−4 M, respectively. MAOx/PVF/GRO/SPCE biosensor showed higher sensitivity (11.98 μA mM−1) for tyramine determination than the DAOx/PVF/GRO/SPCE biosensor (7.99 μA mM−1). The substrate specifity of the biosensors to other biogenic amines namely histamine, putrescine, spermine, spermidine, tryptamine, β‐phenylethylamine and cadaverine was also investigated. The developed biosensors were successfully used for tyramine determination in cheese sample.
