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.
L-dopa production has been improved by adding a reducing agent during fermentation and by simultaneous addition of quinic
or shikimic acid [9, 10].
