Inhibitory effect of some plant extracts on growth of some bacteria and fungi pathogens

الملخص EN

The antimicrobial activity of ethologic extracts of Pomegranates (Punic gradation L.) pericarps and Celery (Apium grave lens L.), Sweet Clover (Mellitus officinal is L.), Alfalfa (Medic ago sativa L.), Fenugreek Seed (Trigon Ella 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.

sativa and P.

gradation extracts contain flavonoids, tannins, alkaloids, sapiens and glycosides compounds, while the other plants were varied in the kinds of these compounds.

Ethologic 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.

gradation and D.

carota ethanolic extracts.

Proteus vulgaris, Klebsiella aero genes and Streptococcus aurous the most susceptible bacteria to the D.

carota and P.

gradation extracts successively, whereas A.

grave lens and T.

feonum-graecum did not have antibacterial activity against most bacteria.

The antifungal activity of the ethologic extracts of deferent plants show significant differences against pathogens test fungi, D.

carota seed and P.

gradation 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.
