Chlorophyll Volatile Compounds

Chlorophyll volatile compounds represent the green, grassy, and herbaceous aromatic notes commonly detected in cannabis cultivars, particularly in fresh or improperly cured material. These compounds are byproducts of chlorophyll breakdown and photosynthetic metabolism, rather than true terpenes or cannabinoids. In cannabis breeding, chlorophyll volatiles are often considered undesirable when present at harvest, as proper curing and drying typically reduces their prominence. Lineage records frequently report that cultivars with shorter flowering cycles or high biomass accumulation may retain higher chlorophyll-related volatiles if post-harvest handling is suboptimal. Understanding and managing these compounds is relevant for seed developers focused on cultivar stability and post-harvest quality control.

Breeders working on cultivar development use chlorophyll volatile profiles as a post-harvest quality indicator rather than a primary selection trait. Selecting parent plants with efficient chlorophyll degradation during maturation can help reduce grassy off-notes in final products.
