CHLOROGENIC ACID: BIOCHEMISTRY AND PHYSI

open access: yesMicrobiology&Biotechnology, 2010
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.

Structural and Antioxidative Features of Chlorogenic Acid

open access: yesCroatica Chemica Acta, 2016
This work contributes to the structure clarification of chlorogenic acid (5-O-caffeoylquinic acid, 5CQA) by comparing the experimental and simulated IR, Raman, 1H-NMR, 13C-NMR, and UV-vis spectra. The lowest-energy conformers in the gas-phase and solution were used for all calculations. Very good agreement between all experimental and simulated spectra
