Caffeic Acid

Caffeic acid is a phenolic compound found across cannabis and many plant species, classified as a hydroxycinnamic acid within the broader polyphenol family. In cannabis plant material, caffeic acid concentration varies by cultivar and environmental conditions, with analytical detection typically performed via HPLC or LC-MS methods. Breeders and researchers studying cannabinoid-to-phytochemical ratios have documented caffeic acid alongside related compounds like ferulic acid and chlorogenic acid in flower and leaf tissues. The compound's presence in cannabis is often discussed in phytochemistry literature examining full-plant biochemical profiles rather than isolated therapeutic contexts. Understanding caffeic acid levels contributes to comprehensive strain characterization in breeding programs focused on complete chemical fingerprinting.

Breeders tracking full phytochemical profiles may monitor caffeic acid as part of broader polyphenol expression, particularly in preservation-focused or heirloom lineages where secondary metabolite diversity is a breeding target. Selecting for consistent caffeic acid levels requires multi-generational phenotyping and controlled growing environments to isolate genetic versus environmental expressio
