Fig. 3From: Tannin profile, antioxidant properties, and antimicrobial activity of extracts from two Mediterranean species of parasitic plant CytinusKilling kinetics of Cytinus hypocystis and Cytinus ruber extracts (at concentrations ranging from 62.5 to 250 μg/ml) and penta-O-galloyl-β-D-glucose (abbreviated as 5-O-galloyl in the graphs, 125 μg/ml) against S. aureus ATCC 33591 (a) and S. epidermidis ATCC 35984 (b). Bacteria were incubated in sodium-phosphate buffer 10 mM, pH 7.4 supplemented with 2% LB in the presence of the antimicrobial compounds for 3 and 24 h. Control (CTRL) represents untreated bacteria. Dashed line represent 3 Logs reduction in CFU count as compared to inoculums. The numbers in the figure legend are the concentrations used expressed in μg/ml. Data are expressed as mean ± standard error of at least three independent experimentsBack to article page
