CHLOROGENIC ACID: BIOCHEMISTRY AND PHYSI
Abstract
Chlorogenic acid (C16H18O9) (CGA) is the ester of caffeic (3,4-dioxycinnamic) acid and one of the stereoisomers of quinic acid. It is the white crystal substance, easy soluble in water, spirit and almost insoluble in nonpolar organic solvents. The alkaline solutions of CGA turn into green colour at the air. CGA is widely spread in Nature and most of all it is contained in coffee beans, seeds of sunflower, leaves of bilberry and white poplar, chicory root. Biosynthesis of CGA occurs only in the plants from phenylalanine through the stage of formation of shikimic acid. CGA possesses strong antioxidant, antiviral, antibacterial and antimycotic characteristics, being of hypoglycemic, hypopolysterynymic, anticancer and hepatoprotective effect.
