Table 2

Inhibition diameter of bacteria (including filter paper).

Extract	Bacteria	Inhibition diameter ± standard deviation^* (mm)
		Leaf	Overall	Control^**
Distilled water	BS	8 ± 0.5	—	—
	SA	9 ± 0.5	—	—
	EC	9 ± 0.00	—	—
Methanol	BS	12 ± 1.5	11 ± 0.6	—
	SA	12 ± 0.6	11 ± 1.0	—
	EC	12 ± 0.6	11 ± 0.6	—

BS is Bacillus subtilis, SA is Staphylococcus aureus, and EC is Escherichia coli.
^*Deviation for 3 times of repetition.
^**Negative control that used dilution solvent without the extract.
