characteristics of fatty acids and essential oil from sweet Fennel foeniculum vulgare mill var dulce and bitter Fennel fruits f vulgare mill var vulgare growing in turkey
Natural Product Research, 2008Co-Authors: Belgin Coşge, Mustafa Kiralan, Bilal GürbüzAbstract:Oil content in sweet and bitter Fennels was obtained 12.22% and 14.41%, respectively. The C18:1 c6, C18:2, C18:1 c9 and C16:0 acids corresponding to ∼97% of total oil was recorded as principal fatty acids. The ratios of essential oil from sweet and bitter Fennels were found similar (average 3.00%). trans-Anethole, estragole and fenchone were found to be the main constituents in both Fennels. The compound with the highest value in the two oil samples was trans-anethole as 95.25% (sweet) and 75.13% (bitter). While estragole was found in bitter Fennel oil in a remarkable amount (15.51%), sweet Fennel oil contained small amounts of estragole (2.87%). Fenchone was found <1% in sweet and ∼5% in bitter Fennel. p-Anisaldehyde in bitter Fennel essential oil, and α-pinene and γ-terpinene in sweet Fennel essential oil were not recorded, and these compounds were found very low or <1%.

Discrimination of Fennel chemotypes applying IR and Raman spectroscopy – discovery of a new γ -asarone chemotype
Julius-Kühn-Archiv, 2016Co-Authors: Andrea Krähmer, Gennadi Gudi, Lothar Henning, Hans Kruger, Hartwig SchulzAbstract:Various vibrational spectroscopy methods have been applied to classify different Fennel chemotypes according to their individual profile of volatile substances. Intact Fennel fruits of different chemotypes could be successfully discriminated by Attenuated Total Reflectance Fourier transform Infrared (ATR-FTIR) and Near Infrared (NIR) spectroscopy. Solvent extracts (CCl4) of the considered Fennel fruits showed characteristic fingerprints with marker bands related to the individual volatile components ( trans -anethole, fenchone, estragole, piperitenone oxide, γ -asarone, limonene) for ATR-FTIR and FT-Raman spectroscopy. Especially νC=C and νC=O absorption bands contribute to the different spectral profiles. Based on hierarchical cluster analysis, the considered Fennel accessions were classified according to gas chromatographic (GC) and vibrational spectroscopic data. Furthermore, even a discrimination of “sweet” and “bitter” Fennel fruits, both belonging to the trans -anethole chemotype, could be successfully performed. All vibrational spectroscopical techniques used in this study are rapid and easy to apply. Hence, they allow different Fennel chemotypes to be reliably distinguished and can also be used for on-site measurement in free nature.

Variability of ferulenol and ferprenin concentration in French giant Fennel (Ferula sp.) leaves
Toxicon, 2019Co-Authors: Gilbert Gault, Sébastien Lefebvre, Etienne Benoit, Virginie Lattard, Denis GrancherAbstract:Few studies have reported quantitative data about the levels of prenylated coumarins in Ferula sp. Yet, the toxicity of Ferula sp. is only due to the presence of prenylated coumarins and to their concentrations and all studies suggest the existence of several chemotypes within the same species or even within the same variety. The aim of this study was to investigate the hypothesis of different chemotypes in french Ferula sp. in relationship with the botanical species. In this objective, the species of giant Fennels and their concentrations in prenylated coumarins were explored. Three different species or subspecies of giant Fennel were detected in continental France: F. communis communis communis L., F. communis catalaunica microcarpa Cauwet-Marc and F. glauca L. Surprisingly, the three species/subspecies of giant Fennels were found to be located in exclusive and well separated geographical areas. In French giant Fennels, ferulenol and ferprenin were detected. Distribution of ferulenol and ferprenin were found to be different between botanical varieties, but also according to the season, the soil and the altitude. Our study seems to suggest that among F. communis species, the same plant can be regarded as poisonous at one point and another as non-poisonous.
