In-Vitro Antibacterial and Antifungal Effects of High Levels of Chinese Star Anise

ABSTRACT This study investigated the in-vitro antibacterial and fungicidal activities of three crude extracts of Illicium verum (absolute methanol, 50% methanol and aqueous extracts) against two Gram-positive bacteria (Staphylococcus aureus and Listeria monocytogenes), two Gram-negative bacteria (Escherichia coli and Salmonella Arizona), and two fungi (Aspergillus fumigatus and Aspergillus niger). The antibacterial action was measured using an agar disk diffusion test, and the minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) were determined. The fungicida...
