Brit.

/nɔːˈnɑːkətiːn/, U.S.

/ˌnɔrˈnɑrkəˌtin/

Origin: Formed within English, by derivation. Etymons: nor- prefix, narcotine n.

Etymology: < nor- prefix + narcotine n.

Chemistry. Now rare.

An organic compound, C₁₉H₁₄N(OH)₃, obtainable as a white solid by heating narcotine with acid, which replaces three methyl groups with hydrogen atoms.

1867 A. Matthiessen & G. C. Foster in Proc. Royal Soc. 16 41 Mention is made of two other new bases derived from narcotine... They are the dimethyl and nor-narcotines,..the latter [being] the product of the action of strong hydriodic acid on narcotine.

1868 A. Matthiessen in Proc. Royal Soc. 17 338 The base may be called normal narcotine, or, shorter, nornarcotine.

1892 H. F. Morley & M. M. P. Muir Watts' Dict. Chem. (rev. ed.) III. 495/1 Nornarcotine, obtained by heating narcotine with fuming HIAq.

1913 T. A. Henry Plant Alkaloids 232 Narcotine contains three methoxyl groups, and when heated in closed tubes with dilute hydrochloric acid furnishes the following series of demethylated derivatives: dimethylnornarcotine.., methylnornarcotine.., and nornarcotine.

1975 J. S. Glasby Encycl. Alkaloids II. 988 The base [sc. narcotine] is unstable to heat and when heated..yields a mixture of dimethylnornarcotine, methylnornarcotine, and nornarcotine.
