Linalool has been reported for insecticidal activity against stored product insects (Ryan and Byme, 1988; Weaver et al., 1991; Sanchez-Ramos and Castanera, 2001) and has potential against cat fleas (Hink et al., 1998). Linalool is most commonly known for promoting relaxation. 1996, Centers et al. Rhodnius prolixus NLM This was realized by a simultaneous substrate feeding and product removal, as shown in Figure 38.3. Most of the mosquitoes caught in the 3 m2 and 6 m2 experiments were Aedes species; the rest were Culex. Volunteers wore short trousers and long‐sleeved shirts. The presence of furanoid linalool oxide (71) as shown in Scheme 17 and 2-methyl-2-vinyltetrahydrofuran-5-one (72) as the unsaturated lactone in the fermentation medium suggested another mode of utilization of linalool (63). Epub 2016 Mar 30. Trends in insect repellent formulations: A review. extracts on . 1996), 3% citronella candles and 5% citronella incense in an outdoor setting increased the repellency rate over the unprotected control by only 42.3 and 24.2%, respectively. 2020 From these four rooms, all furniture was removed except for two chairs. In fact, studies have shown that linalool brings elevated stress levels to almost normal conditions. After 3.7 days the biotransformation was complete and the resin was eluted with ethanol. All differences were considered statistically significant if p<0.05. Assessment of the repellent effect of Lippia alba essential oil and major monoterpenes on the cattle tick Rhipicephalus microplus. Outdoors, citronella diffusers placed 6 m from mosquito traps repelled female mosquitoes by 22%, linalool repelled females by 58%, and geraniol repelled females by 75%.

When the number of mosquitoes collected by the non‐protected control volunteer was compared to the number collected by the protected volunteers, it was found that the repellency rate of citronella diffusers was 68%, linalool diffusers 93%, and geraniol diffusers 97%. Linalool acts on the nervous system affecting ion transport and release of acetylcholinesterase (Lopez and Pascual-Villalobos, 2015). 2007). 0 Sweet and clove basil oils showed an inhibitory activity against Morganella morganii, which can produce histidine decarboxylase to form histamine in fish during storage, and thus can reduce the incidence of histamine fish poisoning (Lomarat et al., 2013). linalool (1), and flowery and fruity impressions are derived from linalool, geraniol, beta-ionon, citronellol, and a variety of ketones, epoxides, and esters (1–3). Within the first hour, about 90% of the mosquitoes, which were ready to feed, entered one of the rooms with the volunteers. The last pathway was also called the ‘prototropic cyclization’.11, Racemic linalool (63 and 63′) is cyclized into cis- and trans-linalool oxide by various microorganisms such as Streptomyces albus NRRL B1865, Streptomyces hygroscopicus NRRL B3444, Streptomyces cinnamonnensis ATCC 15413, Streptomyces griseus ATCC 10137, and Beauveria sulfurescens ATCC 7159.43, Aspergillus niger isolated from garden soil biotransformed linalool and its acetates to linalool (63), 2,6-dimethyl-2,7-octadiene-1,6-diol (8-hydroxylinalool) (64a), α-terpineol (80), geraniol (22), and some unidentified products in trace amounts.25,26. Immediately before each trial, the exposed skin on each volunteer was cleaned with 70% isopropyl alcohol. On average, geraniol, linalool, and citronella diffusers all provided significant protection to volunteers compared to controls (Figure 1) F(4,5)= 645.6, p<0.0001. Characterization of a specific odorant receptor for linalool in the Chinese citrus fly Bactrocera minax (Diptera: Tephritidae).

This terpene can also influence CYP enzymes in rat liver, suggesting that it can alter the pharmacokinetics of cannabis administration (Noskova, Dovrtelova, Zendulka, Řemínek, & Jurica, 2016). It is also antinociceptive at high doses in mice via ionotropic glutamate receptors (Batista et al., 2008).

Geraniol and linalool, isomers of each other, are monoterpene alcohols found in many plant essential oils such as citronella and thyme respectively (Choi et al.
