cinchonine singular
cinchonines plural

Morphology

cinchonine = cinchona (opaque) = cinchona + ine

Although formed from the plant name plus the chemical suffix '-ine', the meaning 'a specific alkaloid/antimalarial drug' is specialized and not derivable by an average B1 learner.

Etymology

Cinchonine comes from the name of the cinchona tree, whose bark from South America was long used to treat 'fevers' and 'malaria'. The same bark gives quinine, and cinchonine is one of the natural chemicals from that bark, which is why the word now names a drug made from cinchona.
