Effects of Achyrocline satureioides Inflorescence Extracts against Pathogenic Intestinal Bacteria: Chemical Characterization, In Vitro Tests, and In Vivo Evaluation

Figure 3

(a) Ferric ion reducing antioxidant power (FRAP Assay). Low concentrations (0.0004 and 0.004 mg/mL) of Achyrocline satureioides freeze-dried extract versus high concentrations (2 and 20 mg/mL) of A. satureioides freeze-dried extract are shown (). (b) Ferrozine assay. Results from the freeze-dried extract versus system () are shown. Hydroxyl radical scavenging properties of (c) low A. satureioides extract concentrations (0.0004, 0.004, and 2 μg ethylenediaminetetraacetic acid (EDTA)/g dry weight) versus high concentrations (20 EDTA/g dry weight) () are shown. (d) Thiobarbituric acid assay. Results from the freeze-dried extract versus system are shown ().
