Question

Quinine is important in treatment of malaria and is extracted from

• A. Bark of Cinchona
• B. Bark of Cinnamon
• C. Stem of Hevea
• D. Leaves of Ocimum

Answer 1

The correct option is A Bark of Cinchona

Quinine is a white crystalline alkaloid having antipyretic (fever-reducing), antimalarial, analgesic (painkilling) and anti-inflammatory properties and a bitter taste. It is a stereoisomer of quinidine, which, unlike quinine is an antiarrhythmic. Quinine contains two major fused-ring systems- the aromatic quinoline and the bicyclic quinuclidine.

Quinine occurs naturally in the bark of the Cinchona tree, though it has also been synthesized in the laboratory. Thus, the correct answer is option A.
