Description
Esculetin (also known as esculetin, 6,7-dihydroxycoumarin and cichorigenin) is a derivative of coumarin. It is a natural lactone that derives from the intramolecular cyclization of a cinnamic acid derivative.
It is present in chicory and in many toxic and medicinal plants, in form of glycosides and caffeic acid conjugates.
This compound is used in some sunscreens, but there is evidence that it acts as a photosensitizer for DNA damage.The sodium salt of its methyl-derivative is used in dermatology for the treatment of varicose veins.
