French lavender

True French lavender grows in the Flaute Provence at an altitude of 600 1500 m. The plants are grown from seeds of the wild lavender ( population lavender). Lavender oil is produced in a yield of 10 25kg/ha. It has the following typical composition (%) m-ocimene (4 10), trans-odimene (1.5-6), 1,8-cineole (<1), camphor (<0.5), linalool (25-38), linalyl acetate (25-45), 1-terpinen-4-ol (2-6), and lavandulyl acetate (>2) [574-583a].

CH3)2C CHCH2CH2C(CH3)OHCH CH2. Linalool is the /-isomer, coridandrol is the d-isomer. Properties Colorless liquid odor similar to that of bergamot oil and French lavender. D 0.858-0.868 (25C), bp 195-199C, angular rotation -2 to +2 degrees. Soluble in alcohol, ether, fixed oils. Combustible. 

USE In perfumery instead of bergamot or French lavender oil since it has an odor similar to these oils.

The production of pure (i )-(-)-linalool involves hydroperoxidation of (].R,2S,5R)-(+)-pinane by air oxygen the pinane enantiomer is obtained by eatalytie hydrogenation of (+)-a-pinene. Another catalytic hydrogenation eonverts the hydroperoxide to (l/ ,2i ,5/ )-(-)-2-pinanol which opens its eyelobutane ring by pyrolytic cycloreversion to the target compound with its pleasant flowery odor, widely used in perfumery instead of bergamot or French lavender. 

French lavender Lavandula angustifolia) and tea tree elaleuca alternifolid) essential oils were also submitted to GC x GG analyses using a nonpolar (5% phenyl-95% dimethylpolysiloxane)-polar (polyethylene glycol) column set [119]. The work, developed using an LMGS, enabled the determination of elution patterns within the space useful for the correlation of component retention behavior with their chemical and structural properties. The GG x GC approach provides higher sensitivity. 

At least it must be mentioned that the mixture of essential oils from the same species but from different geographical sources cannot be called an adulteration.

Bertram and Walbaum found that linalyl acetate was the principal constituent of French lavender oil, and that linalol was also present in the form of esters of butyric, valerianic, and caproic acids. A anall amount of free linalol is also present in the oil.
