Cinnamon oil Usage And Synthesis

Chemical Properties

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; n²⁰_D 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.

Chemical Properties

The volatile oil obtained by steam distillation from the dried inner bark of the shoots of coppiced, cultivated bushes of C. zeylanicus Nees. It has an odor of cinnamon and a spicy burning taste.

Physical properties

It is a yellow liquid and soluble in most fixed oils and propylene glycol. It is insoluble in glycerin and in mineral oil.

Occurrence

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.

Uses

Used extensively as spice and flavoring in foods, beverages, pharmaceuticals. Ingredient in spice blends such as garam masala.

Uses

cinnamon oil (Cinnamomum zeylanicum) is said to have a stimulating effect on the skin. It can also be used for fragrance. Widely recognized for its tonic and antiseptic properties, cinnamon oil is very important in traditional pharmacopoeia. Cinnamon oil is used in a wide variety of skin care and make-up preparations. It is obtained from distillation of the plant’s leaves. It can cause irritation if used in high doses.

Uses

cinnamon bark oil has similar properties to those of cinnamon oil, but this distillation of the plant’s bark is considered of much higher quality than extractions from the plant’s leaves. use in high doses or in high concentrations could produce skin irritations.

Definition

Extractives and their physically modified derivatives. Cinnamomum cassia, Lauraceae.

Preparation

By steam distillation of the dried inner bark of the shrub C. zeylanicum Nees (Guenther. 1950).
Steam distillation is the simplest method to extract the essential oil from cinnamon. Steam distillation is mostly used to extract various types of essential oils. The process is cheaper than other extraction methods. It does not require any solvent and is safer than other methods.

Essential oil composition

The chief constituent of cinnamon bark oil is cinnamic aldehyde

Composition

Cinnamaldehyde and eugenol have been reported to be the main constituents in the oil and extract of C. zeylanicum, while others have also reported eugenyl acetate. However, the composition of cinnamon oil, and hence its potential use, depends very much on the species that is distilled as well as the part of the plant which is utilized. Cinnamon bark oil contains cinnamaldehyde as the major constituent, while cinnamon leaf oil’s major constituent is eugenol rather than cinnamaldehyde. Cinnamon has been found to be effective in inhibiting the mycotoxigenic Aspergillus species Aspergillus parasiticus.

Biochem/physiol Actions

Taste at 10 ppm

Safety Profile

Poison by skin contact. Moderately toxic by ingestion and intraperitoneal routes. A human skin irritant. Mutation data reported. See also CINNAMALDEHYDE and ALDEHYDES. When heated to decomposition it emits acrid smoke and irritating fumes.

Metabolism

Cinnamic aldehyde, the chief constituent of cinnamon bark oil, is oxidized to cinnamic acid, which is then degraded to benzoic acid (Williams, 1959). Additional published data
