4.1 Absorption, Distribution and Excretion

... Permeation of Salvia desoleana Atzei & Picci essential oil (linalyl acetate, 26.8%) through the porcine buccal mucosa is possible in vitro. /Salvia desoleana Atzei & Picci essential oil (linalyl acetate, 26.8%)/

The percutaneous absorption of a massage oil containing lavender oil was studied following application to the skin of a male subject (age 34 yr). Within 5 min after application, traces of linalool and linalyl acetate, the main constituents of lavender oil, could be detected in the blood. After 20 min, maximum concentrations of 100 ng/mL linalyl acetate and 121 ng/mL linalool were reached. Within 90 min most of the lavender oil was eliminated. It was concluded that lavender oil is rapidly absorbed through the skin and is excreted within 90 minutes.

4.2 Metabolism/Metabolites

Esters are readily hydrolyzed by carboxylesterases or esterases. Linalyl acetate has been demonstrated to be hydrolyzed in vitro in rat blood and liver preparations. It is expected to be readily hydrolyzed in vivo. Acetate is a normal constituent of the body. The metabolism of linalool is known and is primarily through glucuronic acid conjugation and excretion

Api AM et al; Food Chem Toxicol 82 Suppl: S39-48 (2015)


In neutral gastric juice, linalyl acetate is slowly (t1/2=121 min) hydrolyzed to a mixture of linalool and the ring closed isomer alpha-terpineol. In acidic artificial gastric juice, linalyl acetate is rapidly hydrolyzed (t1/2<5 min) to yield linalool, which rapidly rearranges into alpha-terpineol. Linalyl acetate was slowly hydrolyzed (t1/2=153-198 min) in intestinal fluid with or without pancreatin. Linalyl acetate also hydrolyzed in homogenates of rat intestinal mucosal, blood, and liver, but at rates much slower than in acidic gastric juice (rate constant for hydrolysis k=0.01-0.0055/min vs. >5/min). Based on these observations it is concluded that linalyl acetate hydrolyzes in gastric juice to yield linalool which, to some extent, is rapidly ring closed to yield alpha-terpineol.

... Hydrolysis occurs more rapidly at the low pH of gastric fluids. The reaction products are linalool and acetic acid (ester hydrolysis). This is supported by the findings of the hydrolysis study ... at pH 4, 7 and 9. Therefore it is expected that linalool is the substance that will enter the systemic circulation after oral uptake of linalyl acetate. Linalool is probably converted to geraniol and its metabolites, 1,5-dimethyl-hexadiene-1,6-dicarboxylic acid and 7-carboxy-5-methylocto-6-enoic acid ...

4.3 Biological Half-Life

Percutaneous absorption ofthe main components of lavender oil were measured in a male human subject. Blood levels of linalool and linalyl acetate were followed for 90 min after the use of a massage oil which contained lavender oil and peanut oil in a 2:98 ratio. The lavender oil contained 24.79% linalool and 29.59% linalyl acetate. A 1500 mg sample of the lavender oil was gently massaged for 10 min into a 376 sq cm area on the abdomen of a 60 kg male volunteer. Blood samples were drawn from the left cubital vein at 0, 5, 10, 15, 20, 30, 45, 60, 75 and 90 min. After adding heparin to the samples, the plasma was centrifuged and the samples were then stored until they were analyzed. Linalyl acetate was absorbed quickly and trace amounts could be detected in the blood 5 min after finishing the massage. The peak plasma concentration was reached at 19 min with a mean plasma concentration of 121 ng/mL. Most of the linalyl acetate disappeared from the blood in 90 min with a biological half-life of 14.3 min.

4.4 Mechanism of Action

In a preliminary experiment, ... lavender essential oil relaxed vascular smooth muscle. Thus, the/se/ ... experiments were designed to investigate the relaxation mechanism of linalyl acetate as the major ingredient of lavender essential oil in rabbit carotid artery specimens. Linalyl acetate produced sustained and progressive relaxation during the contraction caused by phenylephrine. The relaxation effect of linalyl acetate at a concentration near the EC50 was partially but significantly attenuated by nitroarginine as an inhibitor of nitric oxide synthase, 1H-(1,2,4)oxadiazolo(4,3-a)quinoxaline-1-one as an inhibitor of guanylyl cyclase, or by the denudation of endothelial cells. In specimens without endothelium, the phenylephrine-induced contraction and phosphorylation of myosin light chain (MLC) were significantly attenuated after the pretreatment with linalyl acetate. The relaxation caused by linalyl acetate in the endothelium-denuded specimens was clearly inhibited by calyculin A as an inhibitor of MLC phosphatase, although not by ML-9 as an inhibitor of MLC kinase. Furthermore, suppression of the phenylephrine-induced contraction and MLC phosphorylation with linalyl acetate was canceled by the pretreatment with calyculin A. These results suggest that linalyl acetate relaxes the vascular smooth muscle through partially activation of nitric oxide/cyclic guanosine monophosphate pathway, and partially MLC dephosphorylation via activating MLC phosphatase.
