Other important examples are 1,2-benzoquinone (ortho-quinone), 1,4-naphthoquinone and 9,10-anthraquinone. The name is derived from that of quinic acid (with the suffix "-one" indicating a ketone), since it is one of the compounds obtained upon oxidation of quinic acid. [ 4 ]
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 ...

In tropical British colonies gin was used to mask the bitter flavour of quinine, which was the only effective anti-malarial compound. Quinine was dissolved in carbonated water to form tonic water ; the resulting cocktail is gin and tonic , although modern tonic water contains only a trace of quinine as a flavouring.
