Detailed Description
CAS NO.:331-39-5
Caffeic acid, C9H8O4 is a naturally occurring phenolic compound, (formerly called a carbolic acid), which is found in many fruits, vegetables, and herbs, including coffee, although varying in amounts depending on the plant.
Caffeic acid has been shown to act as a carcinogenic inhibitor. It is also known as an antioxidant in vitro and also in vivo.
Caffeic acid is a yellow crystalline acid that is soluble in hot water and alcohol. It is related to cinnamic acid, but it has two hydroxyl groups not found in cinnamic acid. Both are part of the carbocyclic carboxylic acid group.
Caffeic acid can be esterified with quinic acid to form chlorogenic acid. Both caffeic acid and chlorogenic acid are found in coffee beans. Caffeine is a different compound than caffeic acid. A derivative of caffeic acid is caffeic acid phenethyl ester (CAPE).
