Antibacterial Activity for Ethanolic and Silver Nano- particles by Fennel (Foeniculum vulgare L.)

Nehia Neama Hussien,


Antibacterial activity of  alcoholic extract and silver nano particles extract by Foneiculum vulgare plant  will be detecting  in growth of two types of gram  positive and negative bacteria.the highest effect  to the ethanolic extract  was observed in the growth of Staphylococcus aureus  by inhibition zone (12mm) then(10mm).  in Pseudomonas aeruginosa  bacteria .while silver nano particles extract showed the highest effect  on the growth of Staphylococcus aureus by inhibition zone reached to (25mm) and in Pseudomonas aeruginosa bacteria by inhibition zone reached to (13mm). Has been also investigating about the ability of alcoholic extract to removal the free radicals that resulting from photolysis of  hydrogen peroxide compound by used different concentration from the extract
