This study demonstrates antimicrobial activity of ocimum gratissimum extracts against bacterial and fungal strains, suggesting potential therapeutic applications.
The aim of this study was to evaluate the antimicrobial activities of the aqueous and alcoholic (ethanol and acetone) extracts of Ocimum gratissimum leaves against different bacterial and fungal strains. Agar well diffusion method has been used to determine the antimicrobial activities of different plant extracts against Gram-positive bacteria (Bacillus subtilis, Staphylococcus aureus), Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), and fungi (Candida albi-cans, Penicillium crysogenum, Asper-gillus niger and Aspergillus flavus). The extracts exhibited both antibacterial and antifungal activities against tested microorganisms. The plant leaves were tested positive for alkaloids, saponins, flavonoids, tannins and other tested phytochemicals in a preliminary phytochemical screening analysis. This study showed that the phytochemicals of leaf extract of Ocimum gratissimum have antimicrobial properties.
