Léon-Albert Arnaud

Research output: Contribution to journalArticlepeer-review


Léon-Albert Arnaud (1853-1915) was a self-educated French chemist, who
in spite of lacking formal academic education, became chair of chemistry at the Museum of National History in Paris. To him we owe the isolation of the poisons tariric acid and tanghinin, the first acetylenic compound discovered in vegetables; the discovery of the alkaloid cinchonamine, notable for the insolubility of its nitrate, the glucoside ouabain, sometime used in the treatment of cardiac affections, and the transformation of cupreine into quinine. He also showed the presence of carotene in the leaves of vegetables and determined the composition of digitalin.
