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 (37248.
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 [1], tartaric acid [2, 7-9], and
quinic acid [4,10,11], thus forming hydroxycinnamoyl-isocitric acid [1], 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.
