الملخص EN

The results of primary chemical statements showed that the aqueous and the alcoholic extras of pollen grains contains phenolic and alkaloids compounds, amino acids and carbohydrates while the amino acids disappeared from the fresh juice and the powder solution.

Also the results showed that the inhibition activity of the aqueous extract presence significant differences in the effect average of the concentration and the effect an average of the bacteria species , and the activity of the aqueous extract against the studied bacteria so reach the highest diameter of inhibition 27mm at the concentration 500 mg/l of the bacteria Salmonella typhimurium , and no inhibition was showed at the concentration 400 mg / l of the bacteria Klebsiella pneumoniae .

The results of the inhibition activity of the alcoholic extract also showed significant differences in the effect average of the concentration and the effect an average of the bacteria species, and the activity of the alcoholic extract against the studied bacteria so reach the highest diameter of inhibition 25 mm at the concentration 500 mg / ml of the bacteria Salmonella typhimurium , and no inhibition was showed at the concentration 400 mg/ ml of the bacteria Klebsiella pneumonia and the bacteria Pseudomonas aeruginosa.

And the results of the inhibition activity of the fresh juice and the powder solution showed excellence of the fresh juice extract on the powder solution so it gives the highest inhibition diameter of the bacteria Salmonella typhimurium which is 37 mm, and the powder solution gives the lowest inhibition diameter of the bacteria Klebsiella pneumonia wich is 29 mm.And the results of the MIC gave the highest value of the alcoholic extract which is 300 mg / l and the lowest values of the fresh juice which is 100 mg / l
