Specimens were extracted by maceration method with three types of solvents with different polarities and steam distillation. The 25% extract using ethyl acetate solvent showed antimicrobial activity against Gram-negative bacteria (<i>Enterobacter</i> spp. and <i>Pseudomonas</i> spp.); Gram-positive bacteria (<i>Listeria monocytogenes</i>); and fungi (<i>Rhizopus oryzae</i> and <i>Penicillium</i> spp.) in well-diffusion assays.

The antimicrobial activity of the extract will increase at a low pH condition (pH 4–5) and is stable in 1–4% salt solution. Although the inhibitory activity was decreased slightly upon heating, the antimicrobial activity was stable up to 15 min of exposure to high temperatures (80<sup>○</sup>C and 100<sup>○</sup>C). Antimicrobial activity of the extract was reported to be higher in a spheroplast and protoplast condition. Leakage of metal ions such as calcium and potassium ions indicated that the activity of the extract could interfere with cell permeability so that the cells become lysed.
