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).
