Cedrene

Cedrene is a sesquiterpene that is found in the essential oil of Cedrus species, such as the Atlas cedar and the Virginia cedar. It is a colorless to pale yellow liquid that has a sweet, woody, and slightly balsamic aroma. Cedrene is used in the perfume industry and in the synthesis of vitamin A.

Chemical Structure

Cedrene is a tricyclic sesquiterpene, which means it has three rings in its structure. The chemical formula of cedrene is C15H24. It has a molecular weight of 204.35 g/mol. The structure of cedrene includes a seven-membered ring, which is a characteristic feature of the cedrane family of sesquiterpenes.

Occurrence

Cedrene is found in the essential oil of several species of cedar trees, including the Atlas cedar (Cedrus atlantica) and the Virginia cedar (Juniperus virginiana). It is also found in the essential oil of other plants, such as rosemary and sage.

Uses

Cedrene is used in the perfume industry for its sweet, woody, and slightly balsamic aroma. It is also used in the synthesis of vitamin A. In addition, cedrene has been studied for its potential antimicrobial and antifungal properties.

Synthesis

Cedrene can be synthesized from farnesyl pyrophosphate, a key intermediate in the mevalonate pathway. The synthesis involves a series of steps, including cyclization and rearrangement, to form the tricyclic structure of cedrene.

Safety

As with all essential oils, cedrene should be used with caution. It can cause skin irritation and should not be ingested. Always consult with a healthcare professional before using any essential oil.
