[3]
Joseph Bienaimé Caventou (French pronunciation: [ʒozɛf bjɛ̃nɛme kavɑ̃tu]; 30 June 1795 – 5 May 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 in a Parisian laboratory located behind an apothecary.
During the same period – while they were searching for quinine in coffee because coffee is considered by several doctors to be a medicine that reduces fevers and because coffee belongs to the same family as the cinchona [quinine] tree – on their part, Messrs. Pelletier and Caventou obtained caffeine; but because their research had a ...
A significant contribution to the chemistry of alkaloids in the early years of its development was made by the French researchers Pierre Joseph Pelletier and Joseph Bienaimé Caventou, who discovered quinine (1820) and strychnine (1818).
[60] [61] In 1820, French researchers Pierre Joseph Pelletier and Joseph Bienaimé Caventou first isolated quinine from the bark of a tree in the genus Cinchona – probably Cinchona pubescens – and subsequently named the substance. [62]
As early as 1818, strychnine was isolated by Pierre Joseph Pelletier and Joseph Bienaimé Caventou from the Ignatius bean (Strychnos ignatii) extracted. [6] With the structural elucidation of strychnine were engaged especially Hermann Leuchs, Robert Robinson and Heinrich Wieland.
