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 fungicidal activity of the star anise extracts was assessed by the agar disk diffusion test, and poisoned food techniques, and the MICs and minimum fungicidal concentrations (MFCs) were determined. The Chinese star anise extracts showed antibacterial and antifungal activities against A. fumigatus. The results of this study suggest that alcoholic extracts are more active than aqueous extracts and that star anise could be used as a natural antimicrobial agent.
