French chemist who is known for his research in partnership with Joseph-Bienaimé Caventou into vegetable bases and the resulting contributions of alkaloid chemistry to the field of medicine. They helped found the chemistry of vegetable alkaloids. They isolated chlorophyll (1817), for which they coined the French name chlorophyle in Ann. de Chimie (1818), IX, 195. Their alkaloid discoveries included strychnine (1818), brucine (1819), quinine (1820), caffeine (1821), and cinchonine. In 1823, using elementary closed-tube analyses in which the alkaloids were combusted, they discovered nitrogen was present in the compounds.
