Phenolic Chemistry

Phenolic chemistry in cannabis refers to the biosynthesis and expression of phenolic compounds—organic molecules containing hydroxyl groups bonded to aromatic rings. These compounds include flavonoids, tannins, and other secondary metabolites that develop during flowering and cure. Phenolic profiles vary significantly across cultivars and environmental conditions, influencing both sensory characteristics and plant physiology. Breeders tracking phenolic expression often observe correlations with terpene production, pigmentation, and structural resilience. Understanding phenolic chemistry is foundational to cannabis genetics work, as these compounds interact with cannabinoids and terpenes in the final plant chemistry. Research into phenolic inheritance remains an active area within cannabis breeding programs.

Breeders select for stable phenolic expression to maintain consistent flavor profiles, color intensity, and plant vigor across generations. Phenolic accumulation patterns are often used as markers for identifying desirable phenotypes during early-generation selection and backcrossing work.
