quinicinen.

Brit.

/ˈkwɪnᵻsiːn/, U.S.

/ˈkwɪnəˌsin/

Origin: A borrowing from French. Etymon: French quinicine.

Etymology: < French quinicine (L. Pasteur 1853, in Comptes rendus hebd. de l'Acad. des Sci. 37 111), apparently < quinique quinic adj. + -ine -ine suffix⁵.

Chemistry.

A reddish-yellow amorphous isomer of quinine and quinidine, which can be obtained from either of these alkaloids by heating.Formula: C₂₀H₂₄O₂N₂.

1854 L. Pasteur in Pharm. Jrnl. & Trans. 13 374 When any salt of this base [sc. quinine] is heated, a new alkaloid is formed, isomeric with it... To the new base I give the name of quinicine.

1878 Harper's Mag. Jan. 313/1 Fluorescent rays do chemical work within the substance, transforming quinine, for example, into quinicine.

1913 T. A. Henry Plant Alkaloids iv. 167 Cinchonicine and quinicine, unlike their generators, are keto-bases and contain one secondary nitrogen atom.

1966 G. E. Trease et al. Text-bk. Pharmacognosy (ed. 9) xxxiii. 624 A large number of alkaloids of lesser importance have been isolated [from cinchona bark]. Some of these, e.g. quinicine and cinchonicine, are amorphous.
