Background & Aim: Lamiaceae is one of the most important families of plants with global transmittal. The family is divided to two major groups: Lamioideae and Nepetoideae. Mentha L. genus has high genetic variation because of different ploidy levels and interspecific interspecific hybridization thus that is possible to select genotypes with excelsior traits as essence content. The genu...
The primary monoterpene accumulated in the glandular trichomes of spearmint (Mentha spicata) is the ketone (-)-carvone which is formed by cyclization of the C(10) isoprenoid intermediate geranyl pyrophosphate to the olefin (-)-limonene, hydroxylation to (-)-trans-carveol and subsequent dehydrogenation. Selective extraction of the contents of the glandular trichomes indicated that essentially al...
We tested the ability of human subjects to distinguish between enantiomers, i.e. odorants which are identical except for chirality. In a forced-choice triangular test procedure 20 subjects were repeatedly presented with 10 enantiomeric odor pairs and asked to identify the bottle containing the odd stimulus. We found (i) that as a group, the subjects were only able to significantly discriminate ...
Naturally occurring compounds belonging to two chemical groups were studied for their capacities to inhibit N-nitrosodiethylamine (NDEA)-induced carcinogenesis in female A/J mice. One group consists of organosulfur compounds found in Allium species, including garlic, onions, leeks, and shallots, and the other, two monoterpenes, i.e., D-limonene and D-carvone. In an initial experiment, in which ...
The trigeminal nerve responds to a wide variety of irritants. Trigeminal nerve fibers express several receptors that respond to chemicals, including TRPV1 (vanilloid) receptors, acid-sensing ion channels, P2X (purinergic) receptors, and nicotinic acetylcholine receptors. In order to assess whether TRPV1 plays a role in responses to a broad array of substances, TRPV1 (along with green fluorescen...
Anethum graveolens L. has been known as an aromatic, medicinal, and culinary herb since ancient times. The main purpose of this study was to determine the chemical composition, antibacterial, antibiofilm, anti-quorum sensing activities essential oil (EO) obtained by hydro-distillation aerial parts. Twelve components were identified, representing 92.55% analyzed oil. Limonene (48.05%), carvone (...
