Terpene Profile Sesquiterpene

Sesquiterpenes are a class of volatile hydrocarbons composed of three isoprene units (C₁₅H₂₄), commonly found across cannabis varieties and other botanicals. Within cannabis, the most prevalent sesquiterpenes include caryophyllene, humulene, and β-myrcene precursors, often contributing to woody, spicy, earthy, and peppery aromatic notes. These compounds are frequently studied in cannabis breeding for their aromatic stability during storage and their interaction with other volatile fractions. Sesquiterpene-rich cultivars are often tagged as expressing deeper, more persistent aromatic profiles compared to monoterpene-dominant varieties. Lineage records frequently report sesquiterpene prominence in Indica-type and landrace cannabis populations, though expression varies significantly across individual plants and phenotypes.

Breeders working in high-sesquiterpene selection often target parent plants showing robust woody or peppery aromatics, as these compounds tend to persist longer post-harvest than lighter volatile fractions. Selection for sesquiterpene profiles is relevant when developing cultivars intended for long-term preservation or distinctive aromatic fingerprinting.
