Etymology: < German ecgonin (F. Wöhler 1862, in Ann. d. Chemie u. Pharm. CXXI. 372), < Greek ἔκγονος , < ἐκ out of, from + γον- , γεν- to produce + -ine suffix⁵.

Chemistry.

An alkaloid base, C₉H₁₅NO₃, obtained by the decomposition of cocaine.

ΚΠ

1864 H. Watts tr. L. Gmelin Hand-bk. Chem. XVI. 304 Chloroplatinate of Ecgonine. A mixture of hydrochlorate of ecgonine with chloride of platinum and strong alcohol.

1885 Jrnl. Chem. Soc. 48 ii. 913 It would seem that cocaine, ecgonine, and isotropine are derivatives of ethyl tetrahydropyridine.

1920 Act 10 & 11 George V c. 46 §8 The drugs to which this Part of this Act applies are morphine, cocaine, ecgonine and diamorphine (commonly known as heroin).

1957 Encycl. Brit. V. 908/2 On hydrolysis with mineral acids or baryta, cocaine breaks up into ecgonine (tropine carboxylic acid), benzoic acid and methyl alcohol... All the ‘cocaines’ are found to be derivatives of a simple base, ecgonine, which contains both a hydroxyl (.OH) and a carboxyl (.COOH) group.

Derivatives

ˈecgonate n. a salt of this.

ΚΠ

1891 Jrnl. Chem. Soc. 60 i. 749 Ethyl ecgonate, C₇H₁₀EtNO₃, is a colourless, viscid liquid.

ecgonic adj.

/ɛkˈɡɒnɪk/ defining an acid obtained from ecgonine.

ΚΠ

1891 Jrnl. Chem. Soc. 60 i. 749 The acid C₇H₁₁NO₃, obtained by the oxidation of lævo-ecgonine, is termed ecgonic acid.

1901 Jrnl. Chem. Soc. 80 i. 291 Ecgonic acid..crystallizes from ethyl acetate or benzene in colourless needles.
