Linalool (40.9%) and linalyl acetate (33.9%) were quantitatively the main components in lavender oil. Linalool was found almost optically pure (88.0% ee; jasmine tea 82.6%) as (R)-(-). "Only [[http://www.leffingwell.com/chirality/linalool.htm|(R)-(−)-linalool]] elicited a significant decrease in heart rate (P < 0.05) and an increase in high-frequency component in comparison with the controls, and produced calm and vigorous mood states." \\ | Linalool (40.9%) and linalyl acetate (33.9%) were quantitatively the main components in lavender oil.

"...two monoterpene synthases (LaLIMS and LaLINS) and one sesquiterpene synthase (LaBERS) were cloned from lavender leaves and flowers. LaLIMS catalyzed the formation of (R)-(+)-limonene, terpinolene, (1R,5S)-(+)-camphene, (1R,5R)-(+)-α-pinene, β-myrcene and traces of α-phellandrene. The proportions of these products changed significantly when Mn2+ was supplied as the cofactor instead of Mg2+. The second enzyme LaLINS produced exclusively (R)-(−)-linalool, the main component of lavender essential oil. LaBERS transformed farnesyl diphosphate and represents the first reported trans-α-bergamotene synthase.

Over 90% of lavender oils is composed of only 12 components occuring at > 1% (with (R)-(-)-linalool and (R)-linalyl acetate together up to 70%), a further 26 compounds are present in amounts of 0.1-1.0%, and the remaining 3% of the oil is compromised of 250 trace compounds with great structural diversity. The undeca-1,3,5-trienes (galbanolenes, 0.02%) and (3E,5Z,8Z)-undeca-1,3,5,8-tetraene (0.004%) contribute considerably to the scent impression of the oil due to their low thresholds and characteristic odor qualities (intense galbanum). Further olfactorly important trace components are Z-jasmone, methyl jasmonate, β-ionone, β-damascenone, coumarin, emthyl salicylate, 2-hydroxycuminal, eugenol, guaiacol, as well as 2-acetylpyridine and 5-isoprenyl-2-methylpyridine. \\ | Over 90% of lavender oils is composed of only 12 components occuring at > 1% (with (R)-(-)-linalool and (R)-linalyl acetate together up to 70%), a further 26 compounds are present in amounts of 0.1-1.0%, and the remaining 3% of the oil is compromised of 250 trace compounds with great structural diversity.
