Pulegone Expression

Pulegone expression refers to cannabis cultivars that produce measurable levels of pulegone, a monoterpene commonly associated with minty, pennyroyal-like aromas. This terpene is chemically distinct from limonene and pinene, though it can co-occur in the same plant. Pulegone presence is influenced by both genetic predisposition and growing conditions, with some lineages—particularly certain Mint Chocolate Chip and heritage mint-forward cultivars—reporting higher baseline pulegone profiles. Breeders interested in minty or herbal aroma complexity often track pulegone as a secondary volatile marker. Documentation of pulegone levels remains less standardized than for major cannabinoids, making phenotype selection and lineage records valuable for consistent expression.

Breeders working in aromatic trait selection use pulegone expression to refine minty or herbal sensory profiles in specialty cultivars. Tracking pulegone-dominant phenotypes across generations helps establish stable terpene families for niche market segments focused on flavor complexity rather than cannabinoid ratio.
