Polyphenol Compounds

Polyphenol compounds are a broad class of organic molecules found in cannabis plant tissues, distinct from volatile terpenes. These include flavonoids, phenolic acids, and other oxidized aromatic compounds that contribute to plant pigmentation, UV protection, and structural integrity rather than aroma. While less aromatic than terpenes, polyphenols influence the plant's oxidative stability, browning during drying and curing, and the sensory profile of aged cannabis. Lineage records frequently report that different cannabis populations accumulate varying polyphenol profiles, with some cultivars showing darker coloration or earthy undertones linked to higher polyphenol content. Breeders and researchers studying cannabinoid stability and post-harvest chemistry often examine polyphenol expression as a marker of plant maturity and chemotype variation.

Breeders working in preservation and post-harvest optimization track polyphenol accumulation to predict curing behavior and long-term cannabinoid stability. Polyphenol profiles are increasingly used as a chemotype descriptor alongside cannabinoid and terpene ratios when selecting parent lines for specific preservation or sensory outcomes.
