General description

Quinine, a cinchona alkaloid found in the bark of the cinchona tree, is known for its anti-malarial property.

Application

Resolving agent for carboxylic acids. Catalyzes the kinetic resolution of furanones.
Quinine has been used as a standard during the chemical evaluation of alkaloids in the hydroethanolic extracts of endophytic fungi obtained from the leaves of Costus spiralis by TLC.
