| Abstract | ||||
| Some propolis samples collected from different regions of Egypt and Syria were in vitro investigated for chemical compositions and antibacterial activity against Staphylococcus aureus, Escherichia coli, and Pseudomorras aeruginosa. Results indicated that the. number of components in the propolis samples extracts were 15 compounds. with different percentages. The HPLC analysis indicated the presence of the following compounds:— Quercetin, Pinostrobin, chrysin, and Galangin as major Flavonoids, and Vallinin. Euganol, Cinnamic, Salicylic acid and phenol. Caffeic acid, Ferulic acid, (3- ohbenzoic, Gallic acid. P- comaric and 3.5 diethoxy benzyl alcohol as Phenolic components. Results obtained indicated variable differences in percentages of the compounds in samples collected from both Egypt and Syria. Susceptibility to several ethanolic extracts of propolis was tested in reference strains of bacteria. Regarding the susceptibility of the tested bacteria strains, all propolis extracts tested showed great growth inhibition zone than control, but with variable degree. The main of inhibition zone of Syrian and Egyptian propolis against the three tested of bacteria strains were 19.33, 15.06, 15.02. 22.94. 21.39, and 18.73 mm, respectively. Further more results obtained indicated that gram positive bacteria was more sensitive to ethanolic propolis extract than gram negative bacteria. | ||||
