Monoterpenoids

Monoterpenoids are a class of volatile organic compounds derived from two isoprene units (C10H16), commonly found across cannabis and aromatic plants. In cannabis, monoterpenoids include limonene, pinene, myrcene, and terpinolene—compounds that contribute to distinctive aromatic profiles and are often studied for their potential interaction with cannabinoids. These molecules evaporate readily at room temperature, which is why they constitute the primary volatile fraction detected in fresh or dried flower. Lineage records frequently report monoterpenoid expression as a heritable trait influenced by genetics and environmental factors during cultivation. Breeders working in cannabis genetics often select for specific monoterpenoid ratios to establish stable aromatic signatures across generations.

Breeders leverage monoterpenoid profiles as sensory markers for strain classification and phenotype selection. Stable monoterpenoid expression across generations helps establish reproducible aromatics and can serve as one indicator of genetic stability in breeding programs.
