[A rapid method for the determination of quinine in soft drinks and other aqueous solutions (author's transl)]. 1976

C G Frischkorn, and H E Frischkorn

Quinine is determined quantitatively with a liquid-chromatographic method in various solutions using silica as a stationary and methanol + 0.5% ammonia as a mobile phase. The approximate concentrations of quinine were found to be between 50.0 to 72.0 mg/1 in the soft-drinks investigated. Beers, which were also investigated do not content quinine. The method presented is also useful for determining quinine in aqueous solutions of various origin.

D011803	Quinine	An alkaloid derived from the bark of the cinchona tree. It is used as an antimalarial drug, and is the active ingredient in extracts of the cinchona that have been used for that purpose since before 1633. Quinine is also a mild antipyretic and analgesic and has been used in common cold preparations for that purpose. It was used commonly and as a bitter and flavoring agent, and is still useful for the treatment of babesiosis. Quinine is also useful in some muscular disorders, especially nocturnal leg cramps and myotonia congenita, because of its direct effects on muscle membrane and sodium channels. The mechanisms of its antimalarial effects are not well understood.
