ABSTRACT:
The present investigation focuses on the antimicrobial potential of leaf extract of Psidium guajava and its isolated fraction against the selected bacterial strains. Ethnolic leaf extract of Psidium guajava and its isolated fraction was more potent in inhibiting the growth of pathogenic Escherichia coli, Staphylococcus aureus and Staphylococcus epidermidis with different degree of inhibition. The antibacterial activity was more effect in isolated fraction compound than the plant extract. The results support the notion that plant extract containing compound may have many roles in pharmaceuticals as antimicrobial formulations.
