Flavonoid Biosynthesis

Flavonoid biosynthesis refers to the biochemical pathways through which cannabis plants produce flavonoids—a diverse class of polyphenolic compounds that contribute to pigmentation, UV protection, and plant structure. Unlike monoterpenes and sesquiterpenes, flavonoids are not volatile aromatics but rather secondary metabolites synthesized from phenylpropanoid and acetyl-CoA precursors. Research in cannabis breeding has identified flavonoid accumulation as a trait influenced by genetics, light exposure, and developmental stage, with different cultivars expressing varying flavonoid profiles. Breeders and researchers study flavonoid diversity partly because these compounds co-occur with cannabinoid and terpene production, potentially reflecting broader metabolic patterns in elite genetics. Flavonoid composition remains understudied compared to cannabinoids, though chromatographic analysis i

Breeders working in phytochemical profiling use flavonoid markers as indicators of metabolic vigor and genetic stability within breeding lines. Selection for robust flavonoid production is sometimes correlated with desired phenotypic traits like pigmentation intensity and environmental stress resilience.
