Antibacterial activity of seed extract fractions tested against E. coli determined by the agar well diffusion method. Each value is the mean ± standard deviation of three replicates.

Fraction (10 mg/wella)	Inhibition zone (mm)b
Ethyl acetate	27 ± 2
Hexane	12.5 ± 1
Water (remaining fraction)	—
Chloramphenicolc	27 ± 2

^a10 mg of dried extract was dissolved in 100 μL of 15% methanol and the whole volume added to the well. —: no inhibition.

^bInhibitory zones in mm, including diameter of the well (6.0 mm).

^c15 μL of 10 mg/mL was added to each well.
