CHEMICAL PROFILES AND ANTIMICROBIAL ACTIVITIES OF ESSENTIAL OIL FROM DIFFERENT PLANT PARTS OF FENNEL (Foeniculum vulgare Mill.)
Omer Elkiran
Abstract
This study aimed to describe the chemical composition of the essential oil (EO) of stems, leaves, flowers, and seeds of F. vulgare, and verify its antimicrobial properties. The EO chemical characterization was simultaneously obtained by GC-MS. In EOs, Estragole was the main compound in the leaf (51.7%), flower (38.9%), and seed (53.3%), while fenchyl acetate (35.3%) was the main compound in the stem. The antimicrobial activities of EOs taken from four different parts of the fennel plant against seven bacterial and two yeast species were investigated using disk diffusion and MIC procedures. EOs showed high activity against all bacteria and fungi tested except E. faecalis and A. niger. However, when the parts of the fennel were compared, EOs obtained from the seed part showed the best effectiveness. In addition, EO extracts presented a MIC value at the concentration of µl/ml against all tested microorganisms except E. faecalis and A. niger. The results of the current study showed that there were differences in the antimicrobial activities and chemical composition of EOs obtained from four different parts of the fennel. As far as we know, this is the first report on the chemical composition and antimicrobial activities of EOs in different organs of F. vulgare in Turkey.
