Quinine. Cinchona Alkaloids (Tryptophan Derived Quinoline Alkaloids)

2014
Quinine is perhaps the only natural drug that has the long tradition of saving thousand millions of malaria- infected people for more than 300 years [1]. The disease malaria immediately reminds of the Cinchona bark and root, for that matter, quinine, their active principle.
