Thujopsene

Thujopsene is a sesquiterpene found in cannabis and various coniferous plants, including cedarwood and juniper species. In cannabis breeding records, this compound is commonly associated with wood, pine, and spice aromatic profiles. Thujopsene presence often correlates with certain chemotype expressions in lineages descended from Asian hemp cultivars and resinous phenotypes. Breeders analyzing terpene profiles frequently detect thujopsene alongside other sesquiterpenes like β-caryophyllene and humulene. The compound's concentration varies significantly across cultivars and growing conditions, making it a secondary marker in strain differentiation rather than a primary classifier.

Breeders working with conifer-forward aromatic traits—particularly those targeting woody or piney phenotypes—monitor thujopsene expression as part of broader sesquiterpene profiling. Its presence in particular parent material can indicate genetic influence from heritage or landrace genetics with established terpenoid signatures.
