| Abstract: | The methanolic extract of Lagerstroemia speciosa (L.) Pers. leaves, locally known as Banaba, collected from Sablan, Benguet Province, Philippines was subjected to phytochemical analysis for secondary metabolites and antibacterial screening against Escherichia coli, Salmonella typhimurium, Staphylococcus aureus, and Pseudomonas aeruginosa using a modified Kirby-Bauer method. Phytochemical analysis revealed the presence of anthraquinones, flavonoids, saponins, and tannins. The extract exhibited high antibacterial activity against three of the bacteria in order of sensitivity as Escherichia coli > Staphylococcus aureus > Pseudomonas aeruginosa, but had no activity against Salmonella typhimurium. The medicinal value of this plant could be attributed to the presence of one or more of the detected metabolites. Antibacterial activity possibly shows a basis for traditional use of the plant as a local health remedy to the indigenous communities of Benguet Province, Philippines. |
