Abstract
The active compounds of beniseeds was extracted using n-hexane, methanol, hot water and cold water to know
the solvent with the highest percentage yield of the active components. Also, the antibacterial activity of each
extract was determined using agar cup plate diffusion method on six diarrhoeagenic bacteria. The result of the
analysis showed that n-hexane had the highest percentage yield (8.25%), while cold water had the lowest
percentage yield (4.20%). Methanol extract recorded the highest inhibitory effect of 39.33 mm of zone diameter
on Bacillus cereus, while cold water had the lowest inhibitory effect of 2.67 mm diameter zone on Enterobacter
faecium. Therefore, n-hexane is the best solvent in terms of high yield of the extract of beniseeds compounds;
methanol however should be used as solvent of extraction of beniseed compounds for antibacterial activity.
