Abstract

This study aimed to establish the antimicrobial effects of aqueous extract of banana leaves and guava leaves against diseases caused by Escherichia coli, Staphylococcus aureaus, and Staphylococcus epidermidis. Musa sp. leaves and P. guajava leaves were collected within the vicinity. The leaves were authenticated by The Botany Division of the National Museum of the Philippine in Manila. The banana leaves and guave leaves were air dried separately for 2 weeks and ground separately into powder using a mechanical blender. Analysis of the antibacterial action of P. guavaja and Musa sp. was done using One-Way ANOVA and Two-Way ANOVA, with post hoc Tukey's test to determine the significance of the results between the means of the zones of inhibition. In summary, the study had proven that P. guavaja has antimicrobial properties against S. Aureaus and S. epidermidis. However, based on results and related literature, it was not affective against E. coli. While, Musa sapientum was not effective against all three microorganisms.
