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.
is tungtungmadic acid which is chlorogenic derivative; while chlorogenic acid is the ester of caffeic acid with quinic acid
which mainly exhibits antioxidative functions (Chung et al.
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.

Some of the most common phenolic acids in apples are: caffeic acid, present in esterified form with quinic acid
(chlorogenic acid); and p-coumaric acid, present in esterified form with quinic acid
(pcoumarylquinic acid), salicylic, and ferulic (Thielen et al.
Standard compounds 3,5-dicaffeoyl quinic acid
(3,5-DCQA) and 4,5-dicaffeoyl quinic acid
(4,5- DCQA) were isolated at the National Center for Natural Products Research (NCNPR), The University of Mississippi, University, MS, USA.
Sweet taste negatively correlated with quinic acid
and the total acid count.

Organic acids which are found in fruit are malic citric and quinic acid
Being rich in powerful antioxidants such as quinic acid
, chlorogenic acid and caddeic acids, it protects against inflammation, and also contains chlorogenic acid which reduces blood glucose levels.
