 "The essential oil of Lavandula latifolia collected from the North of Tunisia was isolated by steam distillation... A total of 40 compounds were identified in the flower parts oil, the principal components being linalool (32.3%), camphor (12.4%), 1,8-cineole (11.7%), lavandulol (8.7%), p-cymen-8-ol (7.7%) and bornyl acetate (4.2%)." \\

 Group I possesses linalool-rich oils (42-54%), with the lowest percentage of camphor (11-13%) and 20-28% of cineole. Group II, whose oils have an intermediate proportion of linalool (31-36%) and higher percentages of camphor (15-18%), limonene, β-caryophyllene and borneol, whereas cineole percentages range from 28 to 34%. The group III is characterized on the one hand by the highest percentage (47.9%) of cineole and on the other hand by their richness in α- and β-pinene, sabinene, myrcene, and sabinene hydrate, but the lowest linalool content (15.1%) and a 16.5% of camphor. Lavandulyl acetate was completely absent in all oils and lavandulol content was 0.2-1.0%. \\

+"The monoterpene alcohol [[http://www.leffingwell.com/chirality/lavandulol.htm|(-)-(R)-lavandulol]] and its acetate can be considered as biogenic internal standards for lavender/lavandin oils, because these irregular isoprenoids are not found in spike oil." \\

 From the forty compounds identified in hydrodistilled oils of dried L.latifolia growing wild in Spain, three (1,8-cineole, linalool and camphor) accounting for more than 70% of the total oil. Linalool and camphor were inversely correlated. The ranges found were limonene 0-3.4%, 1,8-cineole 6.6-57.1%, camphor 1.1-46.7%, linalool 3.7-61.1%, linalyl acetate 0-0.8%, α-terpineol 0-2.9%. \\
