Abstract

The peels of locally endemic fruits musa acuminata (banana) and ananas comosus (pineapple) were screened for possible antimicrobial effects. The fruits were purchased from University of the Philippines-Los Banos and were tested using the disc-agar diffusion method against the gram-negative bacteria escherichia coli, and pseudomonas aeruginosa, and the gram-positive bacteria methicillin-resistant staphylococcus aureus. Results showed that the peel extracts of all fruits exhibited zones of inhibition on at least one of the bacteria used in the study. Among the extracting solvents used, methanolic peel extracts of the fruits were found to demonstrate the largest and highest number of zones of inhibition, while ethyl acetate peel extracts shown to exhibit the least number of zones of inhibition. The results of the present study further demonstrated the presence of antimicrobial effects in the peels of the different fruits.
