Chlorogenic acid (CGA) is a natural chemical compound which is the ester of caffeic acid and (?)-quinic acid. It is an important biosynthetic intermediate. Chlorogenic acid is an important intermediate in lignin biosynthesis. This compound, known as an antioxidant, may also slow the release of glucose into the bloodstream after a meal.
The term chlorogenic acids can also refer to a related family of esters of hydroxycinnamic acids (caffeic acid, ferulic acid and p-coumaric acid) with quinic acid.
Despite the "chloro" of the name, chlorogenic acids contain no chlorine. Instead, the name comes from the Greek ?????????? (light green) and -???????? (a suffix meaning "giving rise to"), because of the green color produced when chlorogenic acids are oxidized
