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.
