Screening of Bunium bulbocastanum for antibacterial, antifungal, phytotoxic and haemagglutination activities

The current study was aimed at screening the bunium bulbocastanum for its antibacterial, antifungal, phytotoxic and haemagglutination activities.the crude methanolic extract and n-hexane fraction showed significant (89%) and good activity (61%) against staphylococcus aureus while the chcl3fraction was moderately active against s.aureus (53%). moderate activitywas shown by the etoac fraction against b. subtilis (44%). this fraction was inactive against p.aerogenosa and s.aureus. the aqueous fraction showed significant activity against b. subtilis (85%), moderate against s.aureus(34 %) and e. coli (33%)and low activity against p.aerogenosa(29%). our results for antifungal assay indicated that all the test samples were inactive against all the test fungi. the phytotoxic activity of the plant at 1000 and 100 μg/ml was: crude methanolic extract (53.33 and 46.66%), n-hexane (46.66 and 26.66%), chcl3 (20 and 6.66%), etoac (46.66 and 26.66%) and aqueous (40 and 33.33%). all the test samples (crude methanolic extract and fractions) of b. bulbocastanum were unable to agglutinate rbcs of the human blood indicating that this species lack phytolectins.
