Abstract : Sonneratia alba plant parts (leaves, fruit, and bark) were investigated to evaluate the antibacterial activity against bacterial pathogens. The disc diffusion method evaluated the antibacterial activity of crude extracts of Mangrove Apple plant parts. The leaves, fruit, and bark of S. alba exhibited a zone of inhibition both in Staphylococcus aureus and Escherichia coli. Among the five treatments tasted for S. aureus, fruits have the highest zone of inhibition. Meanwhile, the crude extracts from S. alba that were tested toward E. coli, fruits showed the highest zone inhibition. The majority of the treatments were classified as bacteriostatic. Based on the result of the study Gram-positive bacteria, S. aureus was more susceptible than the Gram-negative bacteria, E. coli. Therefore, it was concluded that Mangrove Apple extracts from pocket Mangrove Forest of RSU-San Agustin Campus, Cabolutan, San Agustin, Romblon, Philippines, exhibited antibacterial potential towards bacteria. And might indeed be used in the pharmaceutical industry and as a traditional medicine for the locals. This study recommends, the extraction of other organic solvents used by another group of mangrove species and the utilization of other test microorganisms for further results on the results on antibacterial potential of mangrove plants against pathogens. In addition, elucidation of the compounds responsible for the bioactivities including identification, sufficient isolation, and purification, and also the analysis of the antibacterial mode of action should be done for natural drug development in the future.
