AB  - The goal of this research was a comprehensive analysis of four wild edible mushroom species, Cantharellus cinereus, Clavariadelphus pistillaris, Clitocybe nebularis and Hygrocybe punicea, which have not been analyzed so far. Extracts of different polarities have been prepared and evaluated for their antioxidant activities by DPPH, ABTS, FRAP, TRP and CUPRAC methods. For all extracts, total phenolic content was determined. Based on the analysis, it was shown that solvent type had a significant effect on the antioxidant capacities of mushroom extracts, so water extracts showed the highest activity. Furthermore, the analysis includes determination of mineral composition, fatty acid profiles and antimicrobial activity. Unsaturated fatty acids, which are very important for human health, are dominant in the studied mushroom species. Linoleic and oleic acid consist of over 50 % of the total fatty acid composition. Seventeen biologically important and toxic elements have been analyzed by ICP-OES and ICP-MS and results showed that the element concentrations were species-dependent. Also, it has been found that analyzed mushrooms did not show any antimicrobial activity. Chemometric analysis was used to understand the connection between the extracts of different polarities.

AB  - Background of the study – Among fruits, berry fruits contain a very large complex of chemical compounds that are responsible for their antioxidant properties. As far as we know there is no data available from cyclic voltammetry studies of berry fruits. Objectives – The first objective of the present work was to investigate the electrochemical properties of antioxidants present in four types of berry fruits: strawberries, blackberries, blueberries and red raspberries. The second objective was to establish the correlation between antioxidant capacities obtained from cyclic voltammograms with those obtained using spectrophotometric techniques. Methods – Evaluation of antioxidant activity of 15 berry samples (strawberry, blackberry, blueberry and raspberry) has been carried out using cyclic voltammetry (CV). CVs were taken in the potential range between 0 mV and 800 mV with a scan rate of 100 mV s-1. Results – A pronounced anodic current peak observed between 0.524 V and 0.540 V in all analyzed berry samples can be ascribed to anthocyanins, which are the major contributors to the antioxidant capacity of investigated berries. Results obtained from CVs were compared with those obtained by using DPPH, ABTS, FRAP and RP assays. ACI parameters were determined for each berry sample by assigning all the assays an equal weight. According to obtained results, the highest ACI had blueberry samples, followed by blackberry, raspberry and strawberry samples. Also, high positive correlations were found between antioxidant capacities deduced from CVs with those obtained using FRAP (R2 = 0.8630, p = 0.0006), RP (R2 = 0.7426, p = 0.0004), DPPH (R2 = 0.7680, p = 0.0001) and ABTS (R2 = 0.8710, p = 0.000002). In addition, high positive correlations were also found between total phenols, flavonoids, anthocyanins and CV antioxidant capacity (R2 = 0.8091, p = 0.0005; R2 = 0.8341, p = 0.0002; R2 = 0.7163, p = 0.0007), respectively. Conclusion – Obtained results showed that the cyclic voltammetry is a suitable method for the determination of the reducing capacity based on the electrochemical properties of compounds under the test.

AB  - Phenolic antioxidants in cocoa powder, dark chocolate and milk chocolate samples are quantified electrochemically using cyclic voltammetry with a glassy carbon electrode. Cyclic voltammograms were recorded from 0 to 800 mV at a scan rate of 100 mV/s. Phenolics with an ortho-diphenol group show the first oxidation peak in the potential range between 370 and 460 mV (vs. Ag/AgCl) in 0.1 mol/L of the acetate buffer, pH=4. The first and third anodic current peaks, close to 670 mV, can be ascribed to the first and second oxidation of the catechin-type flavonoids that are present at a high concentration in samples. The second peak at around 560 mV can be ascribed to phenolic acids. Procyanidins B1, B2, B3 and B4 did not have any visible waves. Strong positive correlation was established between antioxidant activities deduced from cyclic voltammograms with those determined using spectrophotometric assays. HPLC method was used for the quantification of individual phenolic compounds.

AB  - The aim of this study was evaluation of individual phenolic compounds and antioxidant activity of commercially consumed black, green, fruit and herbal tea infusions in Serbia in order to characterize the quantity and quality of teas. The most abundant compound was gallic acid, followed by caffeic acid, rutin, (+)-catechin and (-)-epicatechin. The main procyanidin was procyanidin B1. The antioxidant activity was measured using five in vitro methods: determination of 1,1-dipheny1-2-picrylhydrazyl radical-scavenging activity (DPPH), 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) radical cation-scavenging activity (ABTS), ferric reducing antioxidant power (FRAP), reduction power (RP) Fe(III) to Fe(II) and cyclic voltammetry (CV). Obtained results of FRAP and of the Fe(III)/Fe(III) method correlated strongly with the total phenolics content (R-2 = 0.92246, R-2 = 0.88084, p  lt  0.0001). Antioxidant power of green tea and bearberry tea was considerably higher than that of black tea. Raspberry and cherry showed the highest antioxidant power among fruit tea infusions. Contribution of phenolic compounds to tea antioxidant activity was also quantified in this study. Stepwise linear regression demonstrated that quantification of different phenolic compounds responsible for tea antioxidant activity was dependent on the method used. Gallic acid, caffeic acid (+)-catechin, (-)-epicatechin, (-)-epigallocatechin, procyanidin B1, procyanidin B2 together made up 43.6-99.9% of the antioxidant activity of tea.
