چکیده
|
The myrtus communis l. leaves samples were collected from five locations of its native grown areas in lattakia,syria,during their blooming seasons (june,2009). essential oil (eo) extraction was carried out by hydro-distillation in a clevenger apparatus. the eo was analysed by both gas chromatography -flame ionization detector (gc-fid) and gas chromatography/mass (gc/ms) techniques. the eo yield of the dry samples was found to be around 1.88%. the main identified components of eo were: μ-pinene 30.40%,1,8-cineole 17.66%,limonene 8.96%,myrtenol 5.78%,and b-caryophyllene 5.00%. the bulk eo and the separated components were tested for their antibacterial activities against escherichia coli o157,salmonella typhimurium,klebsiella pneumoniae,yersinia enterocolitica o9,brucella melitensis,proteus spp.,and pseudomonas aeruginosa by using broth micro-dilution method. it was found that citronellal and nerol were the most effective components against all pathogens.
