campestris chemically it is the ester of caffeic acid and quinic acid
, 3-O-caffeoylquinic acid.
Chlorogenic acid is a phenolic compound formed by esterification of caffeic acid and quinic acid
. This compound has been shown to have an anti inflammatory effect in various animal experiments.
The highest concentration was determined as Quinic acid
Commercial standards of (+)-catechin, caffeic acid, coumaric acid, and quinic acid
were obtained from Extrasynthese (Genay, France).
For instance, secondary metabolites such as hydroxycinnamic acid (HCA) derivatives have the potential to form conjugates with organic acids such as isocitric acid , tartaric acid [2, 7-9], and quinic acid
[4,10,11], thus forming hydroxycinnamoyl-isocitric acid , hydroxycinnamoyl-tartaric acid [2, 7-9], and hydroxycinnamoyl-quinic acid [4, 10, 11], respectively.
Chlorogenic acid (CGA) composed of coffee acid and quinic acid
is an effective ingredient of many foods and medicines and widely exhibits biological effects.
The results indicated the presence of quinic acid
and its derivatives, 5-caffeoylquinic acid and 3, 5-dicaffeoylquinic acid.
Then there's quinic acid
, extracted from a South African plant that survives long periods of drought before resurrecting itself at the first drop of rainfall, working to protect the skin's membrane structures from dehydration.
The main ones are caffeoylquinic acid and its derivatives and quinic acid
and its derivatives (Table 1).
RLAR-inhibitory potential of SHL constituents depends on the site of quinic acid
and/or other residues of the -COOH position in the caffeic acid structure (compound 2 > 4 > 3).
The main compounds of FCL were quinic acid
, gallic acid, and ethyl gallate.
They are esters formed from quinic acid
and two units of caffeic acid.
