Caffeic acid is a naturally occurring phenolic acid and a key member of the hydroxycinnamic acid family.
It is widely distributed in plants, including coffee beans, fruits, vegetables, and various medicinal herbs such as Echinacea purpurea et Salvia miltiorrhiza.
As a central intermediate in the biosynthesis of lignin and other phenylpropanoids, caffeic acid plays a critical role in plant defense mechanisms against pathogens and environmental stress.
Caffeic acid is extensively used in pharmaceutical research, nutraceutical formulations, functional foods, cosmetic products, and as a reference standard in analytical chemistry.
Synonymes : 3,4-Dihydroxycinnamic acid, 3-(3,4-Dihydroxyphenyl)-2-propenoic acid, trans-Caffeic acid, NSC 57197
