Thujene

Thujene is a natural organic compound classified as a monoterpene. It is found in a variety of plants and is a major component of the essential oil of Thuja species, from which its name is derived. Thujene exists in two isomeric forms, alpha-thujene and beta-thujene, and is known for its distinctive, spicy aroma.

Chemistry

Thujene is a bicyclic monoterpene that consists of a six-membered ring fused to a four-membered ring. It is a colorless liquid that is insoluble in water but soluble in organic solvents such as ethanol and diethyl ether. The chemical formula of thujene is C10H16.

Isomers

Thujene exists in two isomeric forms, alpha-thujene and beta-thujene. Alpha-thujene is the more common isomer and is characterized by a strong, spicy aroma. Beta-thujene is less common and has a milder, more woody scent.

Natural Occurrence

Thujene is found in a variety of plants, including sage, eucalyptus, and cannabis. It is a major component of the essential oil of Thuja species, such as Thuja plicata (western red cedar) and Thuja occidentalis (eastern white cedar).

Uses
