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]
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 ...
Quinoline is a heterocyclic aromatic organic compound with the chemical formula C 9 H 7 N. It is a colorless hygroscopic liquid with a strong odor. Aged samples, especially if exposed to light, become yellow and later brown.
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.
Its signature taste is a result of inherently bitter lemon pith being reinforced by the bitter alkaloid quinine. The principal difference between tonic water and bitter lemon is the lemon juice, pith, and peel. The juice adds sour, offset by additional sweetener, and the oily peel fragrance. The generic bitter lemon drink dates back to 1834. [1]
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.
The article that introduced the concept of "alkaloid". The name "alkaloids" (German: Alkaloide) was introduced in 1819 by German chemist Carl Friedrich Wilhelm Meissner, and is derived from late Latin root alkali and the Greek-language suffix -οειδής-('like').
Parthenium integrifolium is a species of flowering plant in the family Asteraceae known by the common names wild quinine, American feverfew, and eastern feverfew. It is native to the eastern and midwestern United States.
