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] It has the chemical formula C22H18O12.
Sources
Cichoric acid has first been isolated from Cichorium intybus (chicory) but also occurs in significant amounts in Echinacea, particularly E. purpurea, dandelion leaves, basil, lemon balm and in aquatic plants, including algae and sea grasses.[3][4]
Biological functions
Cichoric acid has been shown to stimulate phagocytosis in both in vitro and in vivo studies, to inhibit the function of hyaluronidase (an enzyme which breaks down hyaluronic acid in the human body), protect collagen from damage due to free radicals, and inhibit the function of HIV-1 integrase.[5][6]
