Terpene Phenolic Interactions

Terpene-phenolic interactions describe the chemical relationships between volatile terpenes and non-volatile phenolic compounds in cannabis tissues. These interactions influence how secondary metabolites express, persist, and degrade during plant development, drying, and storage. Phenolic compounds—including flavonoids and phenolic acids—can stabilize or modify terpene profiles through binding, oxidation, and co-extraction during processing. Understanding these dynamics is relevant to breeders developing stable aromatic profiles and to cultivators managing post-harvest chemistry. While terpenes provide the volatile aromatic signature, phenolics contribute to plant color, UV resistance, and overall phytochemical complexity. Research into these interactions remains active among cannabis chemistry and genetics researchers.

Breeders working with terpene stability and flavor expression often select for phenolic-rich plant material, as phenolic compounds can preserve or enhance terpene retention in cured flower. Lines with balanced terpene-phenolic ratios may show more consistent aromatic expression across generations.
