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%.

Repellent activity of constituents identified in Foeniculum vulgare fruit against Aedes aegypti (Diptera: Culicidae)
Journal of Agricultural and Food Chemistry, 2002Co-Authors: Do Hyoung Kim, Soon-il Kim, Kyu-sik Chang, Young-joon AhnAbstract:The repellent activity of materials derived from the methanol extract of fruits from Foeniculum vulgare against hungry Aedes aegypti females was examined using skin and patch tests and compared with that of the commercial N,N-diethyl-m-toluamide (deet) and (Z)-9-octadecenoic acid. The biologically active constituents of the Foeniculum fruits were characterized as (+)-Fenchone and (E)-9-octadecenoic acid by spectroscopic analyses. Responses varied according to compound, dose, and exposure time. In a skin test with female mosquitoes, at a dose of 0.4 mg/cm2, (+)-Fenchone and (Z)-9-octadecenoic acid exhibited moderate repellent activity at 30 min after treatment, whereas deet provided >1 h of protection against adult mosquitoes at 0.2 mg/cm2. (Z)-9-Octadecenoic acid was a more potent repellent agent than (E)-9-octadecenoic acid. (+)-Fenchone and (E)-9-octadecenoic acid merit further study as potential mosquito repellent agents or as lead compounds. Keywords: Natural repellent; mosquito; Aedes aegypti; Foenic...

contact and fumigant activities of constituents of foeniculum vulgare fruit against three coleopteran stored product insects
Pest Management Science, 2001Co-Authors: Do Hyoung Kim, Young-joon AhnAbstract:The insecticidal activities of materials derived from the fruit of fennel, Foeniculum vulgare, against adults of Sitophilus oryzae, Callosobruchus chinensis and Lasioderma serricorne were examined using direct contact application and fumigation methods. The biologically active constituents of the Foeniculum fruits were characterized as the phenylpropenes (E)-anethole and estragole, and the monoterpene (+)-Fenchone, by spectroscopic analysis. Responses varied with insect species, compound, dose and exposure time. In a filter paper diffusion test, estragole at 0.168 mg cm−2 caused 91% mortality to S oryzae adults within 1 day after treatment (DAT), whereas (+)-Fenchone and (E)-anethole gave over 90% mortality at 2 and 4 DAT, respectively. Against C chinensis adults, all test compounds revealed potent insecticidal activities at 0.021 mg cm−2 at 2 DAT. Against L serricorne adults at 0.105 mg cm−2, (E)-anethole gave 100% mortality at 1 DAT, whereas 90 and 60% mortality at 4 DAT was achieved with estragole and (+)-Fenchone, respectively. In a fumigation test, the test compounds were much more effective against adults of S oryzae, C chinensis and L serricorne in closed cups than in open ones, indicating that the insecticidal activity of test compounds was largely attributable to fumigant action. As naturally occurring insect-control agents, the F vulgare fruit-derived materials described could be useful for managing field populations of S oryzae, C chinensis and L serricorne. © 2001 Society of Chemical Industry
