Title: Joseph Caventou, French Pharmacist
Caption: Joseph Bienaimé Caventou (June 30, 1795 - May 5, 1877) was a French pharmacist. He was a professor at the École de Pharmacie (School of Pharmacy) in Paris. He collaborated with Pierre-Joseph Pelletier (March 22, 1788 - July 19, 1842) 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: chlorophyll, emetine, strychnine, brucine, cinchonine, quinine, caffeine. 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.
