Sesquiterpenes Class

Sesquiterpenes are a large class of volatile organic compounds found in cannabis and many plants, characterized by a 15-carbon backbone (C15H24). Unlike monoterpenes, sesquiterpenes are heavier molecules that often contribute to deeper, earthier, and more complex aromatic profiles in cannabis cultivars. Common sesquiterpenes in cannabis include caryophyllene, humulene, and β-myrcene, each with distinct chemical structures and volatility patterns. Breeders and researchers track sesquiterpene ratios as part of phytochemical profiling to understand strain-specific terpene signatures. Sesquiterpenes typically emerge later in flower development than monoterpenes and may persist longer during storage and combustion due to their higher boiling points.

Cannabis breeders monitor sesquiterpene expression when selecting for specific aromatic and flavor profiles, as these compounds contribute substantially to the final chemotype. Understanding sesquiterpene stability and expression is relevant for preserve strain identity across generations and environmental conditions.
