Joseph Bienaimé Caventou


Joseph Bienaimé Caventou was a French pharmacist. He was a professor at the École de Pharmacie in Paris. He collaborated with Pierre-Joseph Pelletier in a Parisian laboratory located behind an apothecary. He was a pioneer in the use of mild solvents to isolate a number of active ingredients from plants, making a study of alkaloids from vegetables. Among their successes were the isolation of the following compounds:
YearIsolated compoundSource
1817Chlorophyll
1817EmetineIpecacuanha
1818StrychnineNux vomica
1819BrucineNux vomica
1820Cinchonine and quinineCinchona bark
1821Caffeine

Quinine sulfate later proved to be an important remedy for the disease malaria. Quinine is the active anti-malarial ingredient in the bark of cinchona tree.
Neither of the partners chose to patent their discovery of this compound, releasing it for everybody to use. In 1823 they discovered nitrogen in alkaloid compounds. Other compounds they discovered include colchicine and veratrine.
The crater Caventou on the Moon is named after him.
