Abstract
Background: Feverfew (Tanacetum parthenium L.) is a herbal plant that has anti- septic, anti-microbial, anti-parasitic and anti-inflammatory effects. The main objective of this study is to evaluate the antimicrobial effect of shoot essential oil (essential oil of the aerial parts of the plant) of the feverfew on a number of microorganisms including gram-negative and gram-positive bacteria, filamentous fungi and yeasts.
Materials and Methods: In this empirical study, plant samples were collected at the full blooming stage. Shoot essential oil was extracted using hydro-distillation technique and Clevenger apparatus. Components of the extract were identified using GC and GC/MS apparatus and its antimicrobial properties were evaluated using diffusion in Agar method (disk diffusion) and dilution in the well (Micro-broth dilution)6T.
Results: Among 35 compounds identified in the essential oil of the feverfew, camphor
(45%), 8Tchrysanthenyl acetate8T (21.5) and camphene (9.6%), were the main components
respectively. Essential oil showed very good antifungal effect which was stronger than its
antibacterial effect. Gram-negative bacteria were less sensitive to the essential oil than
gram-positive bacteria. The mean diameter of inhibition zone, in the bio-assessment of the
effect of feverfew essential oil on gram-positive bacteria and fungi was respectively more
than the effect of vancomycin and amphotericin B and this effect on gram-negative
bacteria was less than the effect of gentamicin. This effect is attributed to the high value of
camphor, chrysanthenyl acetate and camphene found in the essential oil.
Conclusion: Feverfew essential oil could be utilized as a sound and harmless substitute for the antibiotics6T.
