Carotenoid Compounds

Carotenoid compounds are lipophilic pigments found in cannabis plant tissues, distinct from terpenes and cannabinoids. These yellow-to-orange molecular structures accumulate in flower and leaf material, particularly under UV exposure and during senescence. While carotenoids do not produce aromatic volatiles themselves, they correlate with certain flavor and visual phenotypes in breeding programs. Lineage records frequently report carotenoid prominence in older landrace cultivars and modern strains selected for specific pigmentation traits. Breeders working in heritage genetics often track carotenoid expression as a secondary marker for stability and environmental stress response.

Carotenoid expression serves breeders as a visual and biochemical marker for plant health, maturation timing, and genetic stability across generations. Selection for carotenoid-rich phenotypes has become relevant in breeding programs focused on terpene diversity and phytochemical complexity, though direct flavor contribution remains secondary to volatile terpene profiles.
