Friedrich Gaedcke first isolates the cocaine alkaloid (1855)

Friedrich Gaedcke, a German chemist, is credited as the first person to isolate the cocaine alkaloid in 1855. He named the substance 'erythroxyline' and published his findings in the journal Archiv der Pharmazie. The specific date and location of his laboratory work are not definitively established in the provided sources, though he studied in Rostock prior to this achievement.

Background and detail

Background. Friedrich Georg Carl Gaedcke (1828–1890) was a German chemist who studied in Rostock between 1850 and 1851. He is recognized as the first individual to isolate the cocaine alkaloid, a tropane alkaloid derived from coca leaves. His work preceded the later refinement and naming of the substance as 'cocaine' by Albert Niemann.

Isolation and Naming. In 1855, Gaedcke successfully isolated the active ingredient from coca leaves. He designated the alkaloid as 'erythroxyline' and published a description of his work in the journal Archiv der Pharmazie. This isolation marked the first time the specific alkaloid was separated from the crude mixture of coca alkaloids.

Publication. Gaedcke's findings were published in 1855 in Archiv der Pharmazie. The sources do not specify the exact day or city where the laboratory work occurred, though he studied in Rostock. The legacy date of October 27, 1855, and location of Göttingen are treated as unverified placeholders due to lack of specific evidence in the supplied passages.
