Free radical scavenging and antibacterial activities of southern Serbian red wines

Antioxidant, antibacterial and cell toxicity effects of polyphenols <i>Fromahmeur bouamer</i> grape seed extracts

“…This result shows an important sensitivity of these bacterial species to GSE at the concentration of 1000 μg/mL. The same results were obtained by Radovanovic et al [27] from wine extract against the Staphylococcus aureus and Escherichia coli bacteria.…”

Antimicrobial Effectiveness of Selected Vranac Wines Against Six Gram-Positive and Six Gram-Negative Bacterial Strains

“…All tested Vranac wines show the highest activity against S. aureus and S. lutea Gram-positive and against E. coli and S. sonnei Gram-negative strains, then the lowest activity against K. pneumoniae. Antibacterial activity of selected red wines was afected by their biochemical composition, expectedly by their phenolic constituents [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The concentrations of some wine phenolic compounds as well as gallic acid, caffeic acid, (+)-catechin, resveratrol, quercetin, quercetin-3-glucoside and malvidin-3-glucoside, determined using HPLC analysis and total phenolic content, determined by UV/VIS spectroscopic analysis are reported in Table 2.…”

“…It is reported about the important antimicrobial role played by organic acids in wine, immediately followed by phenolic acids and then by flavonoids [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Also, antimicrobial efficacy of the wine may be also enhanced by other components of the inherent present in wine, as low pH.…”

“…The fact that microorganisms nowadays tend to develop resistance toward drugs, coupled to the undesirable side effects of certain antibiotics offer considerable potentials for the development of new effective antimicrobial agents [1][2][3][4][5][6]. It is well known that wine grape possesses therapeutically properties, attributed mainly to high polyphenolic content [7][8][9][10].…”

Chemical and biological investigations of Dillenia indica Linn.

“…Antimicrobial screening: The disc diffusion method (Radovanović et al, 2009) was used to test antimicrobial activity against thirteen bacteria and three fungi. Solutions of known concentration (µ g/mL) of the test samples were made by dissolving measured amount of the samples in calculated volume of solvents (chloroform on methanol).…”
