Essential oil extraction, chemical analysis and anti-Candida activity of Foeniculum vulgare Miller – new approaches

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.

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

Foeniculum Vulgare

The effect of the addition of four different halide-free ionic liquids (ILs) during the maceration step on Foeniculum vulgare essential oil (EO) extraction by hydrodistillation was investigated. The EO yields and their chemical composition were also evaluated, as well as the possibility of reusing the IL aqueous solutions. Although all the investigated ILs were able to increase EO yields, 1,3-dimethylimidazolium dimethylphosphate (IL1) showed the best performance. In particular, the 1 : 1 IL1–water mixture increased the EO yield by ~40 %, even after three reuses, maintaining practically the same volatile profile.
