Quinine is an alkaloid, a naturally occurring chemical compound. [5] How it works as a medicine is not entirely clear. [5] Quinine was first isolated in 1820 from the bark of a cinchona tree, which is native to Peru, [5] [9] [10] and its molecular formula was determined by Adolph Strecker in 1854. [11]
Quinquina is an aromatised wine, a variety of apéritif.Traditionally quinquinas contain cinchona, which provides quinine, introduced to Europe from Peru in the 17th century by Spanish missionaries, [citation needed] and used both in treating malaria [1] and as the principal ingredient in tonic water.
Cinchonism is a pathological condition caused by an overdose of quinine or its natural source, cinchona bark. Quinine and its derivatives are used medically to treat malaria and lupus erythematosus. In much smaller amounts, quinine is an ingredient of tonic drinks, acting as a bittering agent. Cinchonism can occur from therapeutic doses of ...
The quinine in tonic water will fluoresce under ultraviolet light. In fact, quinine will visibly fluoresce in direct sunlight against a dark background. [19] The quinine molecules release energy as light instead of heat, which is more common. The state is not stable, and the molecules will eventually return to a ground state and no longer glow ...
Dubonnet was first sold in 1846 by Joseph Dubonnet, in response to a competition run by the French Government to find a way of persuading French Foreign Legionnaires in North Africa to drink quinine. [4] Quinine combats malaria but is very bitter. Ownership was taken over by Pernod Ricard in 1976.
Among the quinoline alkaloids are the cinchona alkaloids quinine and quinidine, which are important due to their therapeutic potential, furthermore cinchonine and cinchonidine, as well as some furoquinoline alkaloids and acridine alkaloids.
Quinine. In Peru, the indigenous people extracted the bark of the Cinchona tree (Cinchona officinalis) [48] and used the extract to fight chills and fever in the seventeenth century. In 1633, this herbal medicine was introduced in Europe, where it was given the same use and also began to be used against malaria.
