The compound is classified as a cyclitol, a cyclic polyol, and a cyclohexanecarboxylic acid. It is a colorless solid that can be extracted from plant sources. Quinic acid is implicated in the perceived acidity of coffee, where it occurs around 13% by weight.

Occurrence and preparation

The compound is obtained from cinchona bark, coffee beans, and the bark of Eucalyptus globulus. It is a constituent of the tara tannins.

Urtica dioica, the European stinging nettle, is another common source.

It is made synthetically by hydrolysis of chlorogenic acid.

History and biosynthesis

::figure[src="https://upload.wikimedia.org/wikipedia/commons/f/f9/Shikimi.svg" caption="page=64}}). Its transformation into [[hippuric acid]] by animal metabolism was studied by German chemist Eduard Lautemann in 1863.Lautemann, E. (1863) [https://babel.hathitrust.org/cgi/pt?id=uva.x002457962;view=1up;seq=21 "Ueber die Reduction der Chinasäure zu Benzoësäure und die Verwandlung derselben in Hippursäure im thierischen Organismus"] (On the reduction of quinic acid to benzoic acid and its transformation into hippuric acid in the animal organism), ''Annalen der Chemie'', '''125''' : 9–13."] ::

Its biosynthesis begins with the transformation of glucose into erythrose 4-phosphate. This four-carbon substrate is condensed with phosphoenol pyruvate to give the seven-carbon 3-deoxy-D-arabinoheptulosonate 7-phosphate (DAHP) by the action of a synthase. Two subsequent steps involving dehydroquinic acid synthase and a dehydrogenase afford the compound.

Derived bicyclic lactones are called quinides. One example is 4-caffeoyl-1,5-quinide.

Dehydrogenation and oxidation of quinic acid affords gallic acid.

Applications and medicinal activity

Quinic acid is used as an astringent.

This acid is a versatile chiral starting material for the synthesis of pharmaceuticals. It is a building block in the synthesis of oseltamivir, which is used to treat influenza A and B.
