and Agustina G. Pattung2The present study sought to perform antibacterial screening of the Lubeg leaf extracts derived from a 12-year Lubeg Plantation at Apayao State College, Payanan, San Gregorio, Luna, Apayao, against Escherichia coli and Staphylococcus aureus. The antimicrobial activity was evaluated using the disk diffusion method. The 100% Lubeg leaf extracts exhibited the highest mean zone of inhibition against E. coli after 20 hours while after 30 hours of incubation, the 50% Lubeg leaf extracts exhibited the highest mean zone of inhibition and active antibacterial activity against E. coli. Meanwhile, the 25% Lubeg leaf extracts exhibited the highest mean zone of inhibition and active antibacterial activity against S. aureus for both 20 hours and 30 hours of incubation. The Lubeg leaf extract has potential antimicrobial activities against these two bacterial strains, revealing its high potential as an antibacterial agent.
