Caffeic acid is a hydroxycinnamic acid, a naturally occurring organic compound. It consists of both phenolic and acrylic functional groups. It is found in all plants because it is a key intermediate in the biosynthesis of lignin, one of the principal sources of biomass. It is known as an antioxidant in vitro and also in vivo. It shows immunomodulatory and antiinflammtory activity. It may be the active ingredient in caffenol, a do-it-yourself black and white photographic developer made from instant coffee. It is also used as a matrix in MALDI mass spectrometry analyses.
