Number of phenolic acids: acetylsalicylic, fumaric, furancarboxylic, malic, and
quinic acids were suggested in green leaves by ID CUBE DART HRMS (Chernetsova et al.
In terms of quantity, the main components in roasted coffee are
quinic acid and citric acids (see Figure 1).
Recovery of
Quinic Acid was estimated by spiking samples of AC-11 and AIO with with 1.
UV-vis spectra were recorded in the range 210-500 nm, while and chromatograms were monitored at 240,254,330 and 440 nm were used for quantification of iridoid glycosides, flavonoids,
quinic acid derivatives, crocins, respectively.
Pero and colleagues (4) while working at Lund University in Southern Sweden were the first to identify
quinic acid analogs as the primary bioactive component of hot water extracts of Cat's Claw called C-Med-100.

This finding led researchers to conclude that
quinic acid esters are the active constituents of water-soluble cat's claw extract.
Four key polyphenols -- chlorogenic acid, condensed proanthocyanidins,
quinic acid and ferulic acid -- contribute to the super-antioxidant potency of CoffeeBerry(R) extract, which drastically outperforms other commonly known natural antioxidants like green tea, pomegranate, vitamin C and vitamin E on the U.
3,5-dicaffeoyl

quinic acid (4), apigenin (5),apigenin-7-O-[beta]-D-glucoside (6), apigenin-4-O-[beta]-D-glucoside (7), luteolin (8).
It's having four polyphenols -- chlorogenic acid, condensed proanthocyanidins,
quinic acid and ferulic acid -- that makes the CoffeeBerry even more potent than such robust antioxidants as green tea, pomegranates, blueberries, vitamin C and vitamin E.
A study of human chlorogenic acid metabolism showed that the unabsorbed chlorogenic acid which reaches the colon is hydrolysed to caffeic acid and
quinic acid by the microflora present there (Olthof et al.
Bioassay-directed fractionation of EHS following by inhibition of 12-0-tetradecanoyl-13-acetate (TPA)-mediated NF-[kappa]B activation led to the isolation of the cyclitols
quinic acid (1) (85.
