Rosewood trees

Bois de Rose. Bois de rose oil is obtained by steam distillation of wood chips from South American rosewood trees, Aniba rosaeodora. The tree, a wild evergreen, grows mainly in the Amazon basin. The oil is used as obtained in perfumery for its sweet, woody-floral odor and as a source of linalool [78-70-6] (3), which it contains to the extent of 70%. Linalool distilled from bois de rose oil is also used directly in perfumery and for conversion to esters, eg, the acetate (1).

Linalool (23) is more properly spelt linalool and pronounced with two distinct o sounds, the first long and the second short. This gives an indication of one of its principal sources, Linaloe oil, the essential oil of the Indian tree Bursera delpechiana, which contains levels of 30% linalool and 45-50% of its acetate. However, it is common practice nowadays to omit the diaeresis and even to speU the name with a single letter o. Other synonyms include linalyl alcohol, Licareol (extract from rosewood), and Coriandrol (extract from coriander). It occurs very widely in nature. The richest source is Ho leaf oil from China and Taiwan, which typically contains >90% linalool and levels as high as 97.5%, have been reported (150). Rosewood oil will typically contain 75-85% linalool and it is a major component of many flower (e.g., 80% in Ifeesia and 75% in honeysuckle) and herb (e.g., 65-80% in coriander) oils. Linalyl acetate is also a frequently encountered component of plant oils. Oils in which it plays a particularly important organoleptic role, include lavender ( 50%) and citrus leaf oils (also 50%).
