Morphogenetic, Ontogenetic and Diurnal Variability in Antimicrobial Activity of Bitter Fennel (Foeniculum vulgare Miller var. vulgare) Essential Oil

Abstract The objective of current study was to determine the chemical constituents and fumigant toxicity of essential oil isolated by hydro-distillation from dry fruit of bitter fennel (Foeniculum vulgare Miller). The chemical composition of the essential oil was assessed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Constituents of the oil were determined as α-pinene (1.6%) and limonene (3.3%), fenchone (27.3%), estragol (3.9%), and (E)-anethole (61.1%). The fumigant toxicity of the essential oil was tested on larvae of the stored product insect Trogoderma granarium Everts. The mortality of larvae was tested at different concentrations ranging from 31.2 to 531.2 μl/l air and at different exposure times (24 and 48 h). Probit analysis showed that LC50 and LC90 following a 48 h-exposure period for essential oil were 38.4 and 84.6 μl/l, respectively. These results showed that the essential oil from F. vulgare may be applicable to the management of populations of stored-product insects.

Abstract Foeniculum vulgare Mill. is a medicinal plant, used as a flavouring agent. The essential oil from F. vulgare has potential antimicrobial and insecticidal effects, and can be used in food industry in order to protect the food resources and food products against microbial and pest’s contamination. The aim of the research was to characterize the volatile components of F. vulgare essential oil by Gas Chromatography/Mass Spectrometry (GC/MS) and Gas Chromatography (GC-FID) and to observe the antimicrobial activity by disk diffusion method and in vapour phase. Also, insecticidal activity of the vapour phase of the essential oil of F. vulgare was detected. We found that major components of the essential oil from F. vulgare were trans-anethole (73.6%), fenchone (6.0%), and limonene (5.7%). Antimicrobial activity on gram-positive, gram-negative, and yeasts was weak in liquid phase, but vapour phase showed stronger activity against B. subtilis at the concentration 250 μL.L−1 (98.65% of bacterial growth inhibition). Vapour phase of essential oil was effective against insects, where 25% concentration had 80% lethality.

Foeniculum Vulgare Miller

In order to investigate the influence of different level of vermicompost and NPK fertilizer fertilizers on yield, growth parameters and essential oil of fennel (Foeniculum vulgare Miller.), an experiment based on complete randomized blocks design with six treatments and three replications at Galogah, in 2012 and 2013 season was carried out. Treatments included NPK fertilizer, vermicompost (5, 10, 15 and 20 t/ha) and control. Analysis of variance showed that plant height, number of main and lateral branches, number of umbrella per plant, number of umbelets per umbrella, seed yield, biological yield, harvest index and the amount of oil produced at different levels of vermicompost and NPK fertilizer statistically significant. Generally results indicated that using 15 t/ha vermicompostshowed more positive effect on recorded traits of fennel (Foeniculum vulgare) than other treatments.DOI: http://dx.doi.org/10.3126/ijls.v9i4.12673
