化学的特性
Cassia oil (Chinese cinnamon oil) is obtained by steam distillation of the
leaves, twigs, and bark of Cinnamomum aromaticum Nees (Cinnamomum
cassia Blume, Lauraceae) mainly growing in China. It is a reddish-brown liquid
with a sweet–spicy, cinnamon-like odor.
d2020 1.052–1.070; n20D 1.6000–1.6140; solubility: 1 vol in 3 vol of 70%
ethanol at 20 ℃; acid number: max. 15; content of carbonyl compounds
(calculated as cinnamaldehyde): min. 80%.
In contrast to cinnamon bark oil, cassia oil contains a considerable amount
of 2-methoxycinnamaldehyde (3–15%) in addition to its main constituent,
cinnamaldehyde (70–88%). Cassia oil is used predominantly in
flavoring soft drinks (cola-type). Annually ≥600 t are produced in China,
smaller quantities in Vietnam.

天然物の起源
Found in the bark of the shrub Cinnamomum zeylanicum Nees (Fam: Laura-ceae). Cinnamon oil is mainly extracted from the bark and leaves of the many species of the genus Cinnamomum of the Laurel family (Lauraceae), which is widely distributed throughout the tropical and subtropical Asia, and from waste products formed during the preparation of cinnamon spice. However, Cinnamomum zeylanicum, native to Sri Lanka, is the chief source of cinnamon spice and oil worldwide.
