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.
Chlorogenic acids contain no chlorine. The name comes from the Greek χλωρός (light green) and -γένος (a suffix meaning "giving rise to"), because of the green color produced when chlorogenic acids are oxidized.
Isomers of chlorogenic acid include 4-O-caffeoylquinic acid (cryptochlorogenic acid or 4-CQA), 5-O-caffeoylquinic acid (neochlorogenic acid or 5-CQA). The epimer at position 1 has not yet been reported.
Isomers containing two caffeic acid molecules are called isochlorogenic acid. It can be found in coffee. There are several isomers such as 3,4-dicaffeoylquinic acid and 3,5-dicaffeoylquinic acid Cynarine (1,5-dicaffeoylquinic acid) is an other isomer with two caffeic acid molecules..
Isomers of chlorogenic acid are found in potatoes.
Chlorogenic acid can be found in bamboo Phyllostachys edulis. as well as in many other plants. It is one of the major phenolic compounds identified in peach and in prunes. It also is one of the phenols found in green coffee bean extract.
Chlorogenic acid is marketed under the tradename Svetol in Norway and the United Kingdom as a food additive used in coffee, chewing gum and mints. Dried sunflower leaves collected immediately after opening are processed into 98.38 % chlorogenic acid extract and marketed in Bulgaria under the name of "Yamiagra" - "Yummyiagra".
