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.{{cite book|author1=John Shi|author2=Giuseppe Mazza|author3=Marc Le Maguer|title=Functional Foods: Biochemical and Processing Aspects|url=https://books.google.com/books?id=r2jLBQAAQBAJ&pg=PA241|date=27 February 2002|publisher=CRC Press|isbn=978-1-4200-1287-3|pages=241–}}

As a suitable marker for the distinction of Echinacea species, it is often assayed using RP-HPLC and Thin layer chromatography (TLC) methods.Bauer R, Khan IA, Wagner H.
