Abstrakt: The mangrove tree is very important for its antimicrobial and healing properties. This study investigated the antibacterial activity of mangrove Rhizophora mucronate and Excoecaria agallocha leaf extracts against Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa and Listeria monocytogenes using a plate diffusion method. The results show significant antibacterial activity in the zone of inhibition against all tested pathogens Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa and Listeria monocytogenes, R. mucronata maximally inhibits Gram-positive Bacillus subtilis with a zone size of 13 mm and Gram-negative Escherichia coli with a zone size of 10 mm. It was observed that the propanol extract showed the maximum zone of inhibition of Pseudomonas aeruginosa (14 mm) followed by Listeria monocytogenes (13 mm). Initial phytochemical screening revealed the presence of alkaloids, flavonoids, steroids, terpenoids and tannins in both extracts. Quantitative evaluation was also performed for both plant extracts. These phytochemicals can cause significant biological activity against the bacterial pathogens studied. [ABSTRACT FROM AUTHOR]
