Abstract
The aim of this study was to determine the effect of Alcoholic petrolium ether extract (Cold & Hot) for leaves of olive (Olea europea) in growth of foar strains of bacteria (i. e.) two gram negative Klebsiella sp. ; Escherichia coli, and two gram Positive Staphylococcus epidermis ; Staphylococcus aureus.
The results of the inhebitor activity of Cold & Hot extract for olive leaves showed different activity against the strains of bacteria that used in this study, the hot olive leaves extract was more antimicrobial activity compared to the cold olive leaves extract.
Concerning the bacterial isolates S. epidermis was more sensitive towards the hot olive leaves extract than the other bacterial isolates, it’s diameter of inhibition zone was (1.6, 1.4, 1.2, 1)cm in concentrations (500, 250, 125, 62.5)mg/ml.
While the all strains of bacteria didn’t show any inhibitor response towards the cold olive leaves extract except Klebsiella sp. In diameter of inhibition zone was (1)cm in concentration (500)mg/ml.
Analysis of the two extracts (Cold & Hot) carried out to determine they are content form flavonoid compounds.
