Research Area: Cancer
Biological Activity:
Caffeic acid is a hydroxycinnamic acid, a naturally occurring organic compound.It has been shown to inhibit carcinogenesis, although other experiments show possible carcinogenic effects. It is also known as an antioxidant in vitro and also in vivo. Caffeic acid also shows immunomodulatory and antiinflammtory activity. Caffeic acid outperformed the other antioxidants, reducing aflatoxin production by more than 95 percent. The studies are the first to show that oxidative stress that would otherwise trigger or enhance Aspergillus flavus aflatoxin production can be stymied by caffeic acid. This opens the door to using natural anti-fungicide methods by supplementing trees with antioxidants. [1][2]

Caffeic Acid is a constituent of plants, probably occurs in plants only in conjugated forms. Caffeic acid is found in all plants because it is a key intermediate in the biosynthesis of lignin, one of the principal sources of biomass. Caffeic acid is one o
