diffusion method. Aqueous extract were able to exhibit
antimicrobial activity. The highest antimicrobial
activity of Tayebat with zone of inhibition of 20 mm
and Al Manna present with zone of inhibition 10 and
20 of different microorganisms. Prebiotic (Al Manna
and Tayebat) could be used as a source of
