Chemical Properties
The volatile oil is obtained by the steam distillation from the wood of Amyris balsamifera L. The yield is approximately
2.5 to 3.0%. Amyris oil has a wood-like odor reminiscent of sandalwood with a burning taste. It is used as a fixative in perfumery
and in flavors, such as Oriental specialties and liqueurs
Chemical Properties
Amyris oil is obtained by steam distillation of the wood from the tree Amyris
balsamifera L. (Rutaceae), which grows in the Caribbean (Haiti) area and around
the Gulf of Mexico. It is a pale yellow to amber, slightly viscous liquid with a mild
wood odor.

Physical properties
It is a clear, pale-yellow liquid. It is soluble in most fixed oils and usually in mineral oil. It is
soluble in an equal volume of propylene glycol, the solution often becoming opalescent on further dilution. It is practically insoluble
in glycerin.
Preparation
The oil is sometimes incorrectly called West Indian sandalwood oil. However,
its composition and odor are different from those of the oils obtained
from sandalwood species. The major components of amyris oil are sesquiterpenoids
such as elemol [639-99-6], ??-eudesmol [473-15-4], and epi-??-eudesmol
[15051-81-7]. Annually～50 t are produced.
