Figure 6

Plate inhibition test of the Achyrocline satureioides (AS) freeze-dried extract (200 mg/mL), prepared from an A. satureioides hydroethanol extractive solution (80% ethanol), and the major flavonoid-aglycone 3-O-methylquercetin (3OM) against (a) Bacillus cereus (ATCC 9634), (b) Staphylococcus aureus (ATCC 1901), and (c) Salmonella enteritidis (ATCC13076). Antibiotic references used as positive controls include chloramphenicol (CLO) (30 μg), amoxicillin (AM) (30 μg), and ciprofloxacin (CIP) (5 μg).
