Abstract

This research aimed at finding out a bioactive content of bulubangkal leaf and extractability of 3 polar solvents, semi-polar and non-polar as Aeromonas hydrophila antibacterial. The sample was extracted by maceration and fractionation methods using n-hexane solvent, ethyl acetate, and methanol. Antibacterial activity was carried out by disk-diffusion agar method. It was found that active agent contained within bulubangkal leaf are saponin, tannin, phenolic, and steroid as A. hydrophilia bacterial based on the antibacterial test by in vitro and in silico methods.
