Chicoric acid (also known as cichoric acid) is a hydroxycinnamic acid, an organic compound of the phenylpropanoid class and occurs in a variety of plant species. It is a derivative of both caffeic acid and tartaric acid.[1]

As a suitable marker for the distinction of Echinacea species, it is often assayed using RP-HPLC and Thin layer chromatography (TLC) methods.[2]
