Cedrene

A sesquiterpene found in essential oils

Cedrene is a naturally occurring sesquiterpene that is found in the essential oils of various plants, particularly in the cedar species. It is known for its distinctive woody aroma and is used in the fragrance industry as well as in traditional medicine.

Chemical Structure

Cedrene is a bicyclic sesquiterpene, which means it consists of two interconnected rings. Its chemical formula is C₁₅H₂₄. The structure of cedrene includes a cyclohexane ring fused to a cyclopentane ring, with various methyl groups attached. There are two isomers of cedrene, known as _-cedrene and _-cedrene, which differ in the arrangement of atoms in the molecule.

Sources

Cedrene is primarily extracted from the essential oils of cedarwood, particularly from species such as Juniperus virginiana (Eastern red cedar) and Cedrus atlantica (Atlas cedar). These oils are obtained through steam distillation of the wood and are rich in cedrene and other terpenes.

Uses

Fragrance Industry

Cedrene is widely used in the perfume industry due to its pleasant woody scent. It is often used as a base note in perfumes, providing a warm and long-lasting aroma. Its scent is reminiscent of freshly cut wood, making it a popular choice for masculine fragrances.

Traditional Medicine

In traditional medicine, cedarwood oil, which contains cedrene, has been used for its purported therapeutic properties. It is believed to have antiseptic, anti-inflammatory, and sedative effects. However, scientific evidence supporting these uses is limited.

Other Applications

Cedrene is also used in the production of insect repellents and as a flavoring agent in food and beverages, although its use in food is less common.

Safety and Toxicity

While cedrene is generally considered safe for use in fragrances and cosmetics, it can cause skin irritation in some individuals. It is important to conduct patch tests before using products containing cedrene on the skin. Inhalation of concentrated cedarwood oil can also cause respiratory irritation.

Related Compounds

Cedrene is related to other sesquiterpenes such as cedrol, which is another major component of cedarwood oil. Cedrol is an alcohol, whereas cedrene is a hydrocarbon.
