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

Figure 2

(a) In vitro effects of Achyrocline satureioides extracts on total radical-trapping antioxidant potential (TRAP). Data are presented as means  ±  SEM of three experiments. Black bars represent A. satureioides extracts and flavonoids compared to the system (i.e., solvents without sample and Trolox = control). extracts versus system (Student’s -test) and freeze-dried extract versus aqueous extract and spray-dried extract. (b) Total antioxidant reactivity (TAR) index, which is related to antioxidant quality, is shown. flavonoids versus Trolox. Aqueous extract: freeze-dried extract prepared from A. satureioides decoction. Both freeze-dried and spray-dried extracts were prepared from an A. satureioides hydroethanol extractive solution (80% ethanol). All extractive solutions were prepared using a plant : solvent ratio of 7.5% (w/v).
