Abstract
In our study, volatile oils, which obtained from Foeniculum vulgare Mill. fruit samples, obtained from cultivars and herbalists, were analyzed for the first time for their compliance with European Pharmacopeae 6.0, for their volatile oil amounts and the contents. Among all the samples only the volatile oil yield of sample FV2 (2.2%) meet the standards present in the Pharmacopea 6.0, the others did not, as for volatile oil content, all the samples complied with the Pharmacopea 6.0. All the volatile oil samples were screened for their invitro antibacterial, and antifungal activities that were evaluated against both standard and the isolated strains of Gram-negative and Gram-positive bacteria, as well as fungi by microdilution method. Susceptibility testing was performed according to the CLSI. Ampicilline, gentamicin, levofloxacin, ketoconazole, and fluconazole were used as the control agents. All the extracts have shown antibacterial activity against Gram-positive standard bacteria ranging between 16 and 64 µg/ml, against Gram-negative standard bacteria at 2-16 µg/ml concentrations ones, while they demonstrated antifungal activity at 8-16 µg/ml concentration. Slight activities were found against tested isolated strain (64-128µg/ml). All the samples demonstrated better inhibition against Acinetobacer baumanii RSKK 02026 with MICs value of 2-4 µg mL-1as compared with the control ampicillin (2µg/ml). Additionally, they have moderate activity against Candida krusei at concentration ranges of 4-16µg/ml
