This study was carried out to show the effect of extracts (aqueous, alkaloid and glycosides) of Eruca sativa Mill. on the fungal growth, the results revealed the inhibitory effectiveness of the aqueous, alcoholic and glycosides extracts of E. sativa by four different concentrations (10%, 20%, 40% and 100% mg/ml) on the growth of three fungal species in three different genera (Aspergillus niger, Fusarium oxysporium and Pencellium sp.). The results showed that these concentrations of the aqueous

... xtracts have an impact on inhibiting the growth of two fungal species (Pencellium sp. and F. oxysporium) variously, while the same concentrations of aqueous extracts did not affect on the growth of A. niger as well as it showed the ineffectiveness of various concentrations of alcoholic extracts in the inhibition of these fungi, whereas it was appeared the effectiveness of the same concentrations of glycoside extracts in the inhibition of two fungi F. oxysporium and Penceillium sp differently, whilst the same concentrations did not inhibit the growth of A. nigar action of glycosides and sulfur glycosides include the interaction with a group (-SH) in cells, which presence in cells proteins' that interact with amino acid cysteine and likewise make bisulfur bond (S-S) and the sulfur group (SH-) has a special stimulators multiply the cells where the sulfur compounds are working on break down this group and consequently will discourage biological activity and replication in the cell (Kyung and Lee, 2001) Conclusions This study concluded that the aqueous extracts of the Eruca sativa with concentrations (10, 20, 40 and 100 mg/ml) has effectiveness in the inhibition of two fungal species Pencillium and F. oxysporium, which the concentration of 20, 100 mg/ml with highest effective inhibition compared to the others, while the concentrations of 10 and 40 mg/ml are the least effective in the inhibition of Pencillium, the alcoholic extracts was ineffective in the inhibition of studied fungus species, whilst the concentration of 20 mg/ml of glycosides extracts seemed inhibitory effective against the species Pencillium that higher than the concentration of 10 mg/ml. and the concentration of 10 mg/ml was only effective in the inhibition of F. oxysporium, however the growth of the species A. niger was not affected by all concentrations of all extracts.
