Pinene is a collection of unsaturated bicyclic monoterpenes. Two geometric isomers of pinene are found in nature, α-pinene and β-pinene. Both are chiral. As the name suggests, pinenes are found in pines. Specifically, pinene is the major component of the liquid extracts of conifers.^[3] Pinenes are also found in many non-coniferous plants such as camphorweed (Heterotheca)^[4] and big sagebrush (Artemisia tridentata).
