Caffeic Acid

Caffeic acid is a phenolic compound found in cannabis and numerous plants, classified as a phenylpropanoid rather than a traditional volatile terpene. In cannabis plant material, caffeic acid exists primarily in non-volatile forms within plant tissues and is commonly associated with the plant's secondary metabolism. Lineage records and phytochemical analyses frequently report caffeic acid alongside other phenolic compounds in various cannabis cultivars. Breeders and researchers studying cannabinoid-rich and terpene-rich strains have documented this compound's presence, though its specific contribution to aroma or sensory profiles remains less characterized than volatile terpenes. Caffeic acid may play roles in plant structure, oxidative processes, and UV protection during growth.

Breeders working with phenolic-compound-rich genetics sometimes monitor caffeic acid levels as part of broader phytochemical profiling. Its presence is often correlated with certain plant lineages and may influence oxidative stability during storage and processing.
