Description of chlorogenic acid

Deion of chlorogenic acid:

a) Has a wide range of biological effects, from insect resistance to human health

b) An important factor in plant metabolism

c) An antioxidant and has anti-fungi effectivity,stronger than the antibacterial effectivity

d) An ester of caffeic acid and quinic acid, a major phenolic compound in coffee,the daily intake of coffee drinkers is 0.05-0.1g

e) Strong antioxidants in vitro and could therefore be contribute to the prevention of disease caused by free radicals Chlorogenic acid, an ester of caffeic acid and quinic acid, is a major phenolic compound in coffee, but is also found widespread in plants and can be isolated from the leaves and fruit . This compound, long known as an antioxidant, also slows the release of glucose into the bloodstream after a meal.

f) Structurally, chlorogenic acid (CGA) is the ester formed between caffeic acid and (L)-quinic aicd(1L-1(OH),3,4/5-tetrahydroxycyclohexanecarboxylic acid). Isomerisation of the quinic acid in position 3, (3-CQA),4 (4-CQA) and 5 (5-CQA). Isomerisation at position 1 has not yet been reported. Isomers of chlorogenic acid are found in potatoes. They are 4-O-caffeoylquinic acid(crypto-chlorogenic acid), 5-O-caffeoylquinic acid (neo-chlorogenic acid), 3,4-dicaffeoylquinic acid and 3,5-dicaffeoylquinic acid.
