Abstract: Shikimic acid (SA) has witnessed a strong increase in recent years due to the increasing demand of the pharmaceutical and cosmetic industry. The SA is used as a precursor for the synthesis of oseltamivir phosphate (Tamiflu®), a potent viral inhibitor and is extracted from the plant Illicium verum Hook which has a limited availability. This article proposed the use of Urochloa plantaginea (Link.) webster and glyphosate, as an alternative source of SA. U. plantaginea plants with 3 - 4 tillers and 4 - 6 leaves were harvest at 3, 6, 9 and 12 days after application (DAT) of low rates of glyphosate. Samples were dried, extracted, analyzed by HPLC and LC-MS/MS. The maximum SA concentrations were observed at 6 days after glyphosate at 36 g.a.e.ha-1 was... |

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... |
