TL;DR: F essential oil yields decreased from the beginning to the end of the flowering stage, whereas L yields remained constant during the year, and fenchone, limonene, and myrtenal appeared to be the more effective on the inhibition of R. solani growth.
Abstract: Essential oils from the stems/leaves (L) and flowers (F) of Lavandula stoechas L. ssp. stoechas growing wild in southern Sardinia (Italy) were extracted by hydrodistillation and analyzed by gas chromatography coupled with flame ionization detector and ion trap mass spectrometry. The major compound was fenchone, accounting for, on average, 52.60% in L and 66.20% in F, followed by camphor (13.13% versus 27.08%, in L and F, respectively). F essential oil yields (volume per dry weight) decreased from the beginning to the end of the flowering stage, whereas L yields remained constant during the year. The nine main compounds derived from two different subpathways, A and B. The compounds that belong to the same subpathway showed a similar behavior during the year. The essential oils were tested for their antifungal activity using the paper disk diffusion method. The essential oils tested were effective on the inactivation of Rhizoctonia solani and Fusarium oxysporum and less effective against Aspergillus flavus....

TL;DR: It was observed that fenchone, γ-terpinene, geraniol and linalool showed a reversible competitive inhibition at least at the enzyme's hydrophobic active site, while the majority of monoterpenoids tested inhibited the enzyme acetylcholinesterase.

TL;DR: Three naturally occurring monoterpenoids, the ketones pulegone, l -fenchone, and the aldehyde perillaldehyde, were selected for further study and were effective against T. castaneum in the fumigation assay; however the toxicity was relatively low in comparison to dichlorvos.

TL;DR: The results of the present investigation demonstrated significant variations in the antioxidant and antimicrobial activities of fennel and chamomile essential oil and extracts of two Egyptian plants as discussed by the authors.

TL;DR: Essential oils from the azoricum and dulce cultivars were more effective antioxidants than that from the vulgare cultivar, while all three cultivars showed similar antimicrobial activity.
Abstract: Essential oils of the fruits of three organically grown cultivars of Egyptian fennel (Foeniculum vulgare var. azoricum, Foeniculum vulgare var. dulce and Foeniculum vulgare var. vulgare) were examined for their chemical constituents, antimicrobial and antioxidant activities. Gas chromatography/mass spectrometry analysis of the essential oils revealed the presence of 18 major monoterpenoids in all three cultivars but their percentage in each oil were greatly different. trans-Anethole, estragole, fenchone and limonene were highly abundant in all of the examined oils. Antioxidant activities of the essential oils were evaluated using the DPPH radical scavenging, lipid peroxidation and metal chelating assays. Essential oils from the azoricum and dulce cultivars were more effective antioxidants than that from the vulgare cultivar. Antimicrobial activities of each oil were measured against two species of fungi, two species of Gram negative and two species of Gram positive bacteria. All three cultivars showed similar antimicrobial activity.
