Abstract
ABSTRACT: The antimicrobial activity of ethanolic extracts of Pomegranates (Punica granatium L.) pricarps and Celery (Apium graveolens L.), Sweet Clover ( Melilotus officinalis L.),Alfalfa ( Medicago sativa L.), Fenugreek Seed (Trigonella feonum-graecum L.) leaves and Carrot ( Daucus carota L.) seeds against some pathogenic fungi , Gram-negative and Gram-positive bacteria were studied. Also, photochemical compound of extracts were determined, results of the chemical tests explain the M. sativ and P. granatium extracts contain flavonoids, tannins, alkaloids, saponins and glycosides compounds, while the other plants were varied in the kinds of these compounds. Ethanolic extracts show significant differences between most plants extracts, possibly due to deferent in the antimicrobial substance contain. All bacteria which were tested have shown susceptible to the P. granatium and D. carota ethanolic extracts. Proteus vulgaris , Klebsiella aerogenes and Streptococcus aureus the most susceptible bacteria to the D. carota and P. granatium extracts successively, whereas A. graveolens and T. feonum-graecum did not have antibacterial activity against most bacteria. The antifungal activity of the ethanolic extracts of deferent plants show significant differences against pathogens test fungi, D. carota seed and P. granatium pericarps extracts report the most inhibited percentage than with the M.officinalis extract, also, a different level in susceptible of Geotrichum candidum and Trichophton montagrophytes fungi have shown with all extracts which had use.
