Flavonoid Chemistry

Flavonoid chemistry refers to the secondary metabolite compounds in cannabis that contribute to pigmentation, UV protection, and aromatic profiles. These polyphenolic molecules—including anthocyanins, catechins, and quercetin—are synthesized alongside cannabinoids and terpenes, creating complex phytochemical signatures. Flavonoid expression is influenced by genetics, light exposure, and growing conditions, making them useful genetic markers in breeding programs. Unlike cannabinoids, flavonoids are present across all plant tissues and remain relatively stable through drying and curing. Researchers have documented strain-specific flavonoid patterns that correlate with lineage and parentage, offering additional tools for cultivar classification beyond THC/CBD ratios.

Breeders increasingly monitor flavonoid profiles as secondary selection criteria when pursuing specific sensory or color phenotypes. Flavonoid stability across generations helps breeders verify genetic purity and track inheritance patterns in hybrid development.
