AB  - This study aimed to estimate the quality (in terms of standard chemical parameters, total antioxidative activity /AO/ and thermal properties) of the fresh strawberry (Fragaria xananassa L. Duch.), raspberry (Rubus idaeus L.) and blackberry (Rubus fruticosusL.) samples grown in the Western Serbia. The examined blackberry variety was found to exhibit the most potent AO (DPPH /2,2-diphenyl-1-picrylhydrazyl/ assay, EC50 4.05 +/- 0.22 mu g and ARP 0.25 +/- 0.03 mu g(-1); Hydroxo-Perhydroxyl Mercury(II) Complex /HPMC/ assay, 0.072 +/- 0.007%/mu L), due to the enriched contents of both total phenolics and anthocyanins. It was actually followed by the raspberry and strawberry samples. Unlike the aforementioned trend for AO, thermal behaviour of all samples was similar. This is first time ever that a DC polarographic HPMC assay has been applied for the characterisation of the fresh berry fruits. Further studies aiming to screen total AO of the soft fruit during growth, storage and processing might be well facilitated by the application of this low cost, rapid, easy-to-handle and reliable electrochemical assay.

AB  - Screens of antioxidant activity (AA) of various natural products have been a focus of the research community worldwide. This work aimed to differentiate selected samples of Merlot wines originated from Montenegro, with regard to phenolic profile and antioxidant capacity studied by survival rate, total sulfhydryl groups and activities of glutathione peroxidase (GPx), glutathione reductase and catalase in H2O2-stressed Saccharomyces cerevisiae cells. In this study, DPPH assay was also performed. Higher total phenolic content leads to an enhanced AA under both conditions. The same trend was observed for catechin and gallic acid, the most abundant phenolics in the examined wine samples. Finally, the findings of an Artificial Neural Network (ANN) model were in a good agreement (r(2) = 0.978) with the experimental data. All tested samples exhibited a protective effect in H2O2-stressed yeast cells. Pre-treatment with examined wines increased survival in H2O2-stressed cells and shifted antioxidative defense towards GPx-mediated defense. Finally, sensitivity analysis of obtained ANN model highlights the complexity of the impact that variations in the concentrations of specific phenolic components have on the antioxidant defense system.
