Also -in, † -eïne.
[ad. It. galipeina (Koerner & Böhringer 1883, in Gazzetta Chim. Ital. XIII. 365), f. mod.L. Galipea, a generic name of the tree producing Angustura bark.]
An alkaloid, C20H21NO3, obtained from Angustura bark. Similarly galipoidine (gælɪˈpɔɪdiːn) [ad. G. galipoidin (Tröger & Runne 1911, in Arch. Pharm. CCXLIX. 184)], an alkaloid, C19H15NO4; galipoline (gæˈlɪpəliːn) [ad. G. galipolin (Späth & Papaioanou 1929, in Monatsh. Chem. LII. 129)], an alkaloid, C19H19NO3.
| 1884 Jrnl. Chem. Soc. XLVI. 341 In the mother-liquors from which the cusparine was originally precipitated..another alkaloïd is found, to which the authors have given the name of galipeïne, C20H21NO3. 1911 Ibid. C. i. 482 Angostura bark contains..a new alkaloid, now named galipoidine. 1912 Ibid. CII. i. 896 Galipine is colourless when pure, and yields colourless salts; the yellow colour usually ascribed to the salts is due to the presence of impurities. 1913 T. A. Henry Plant Alkaloids 404 Galipine, C20H21O3N, crystallises from alcohol or ether in prisms. Ibid., Galipoidine, C19H15O4N, m.p. 233°, is sparingly soluble in most organic solvents. 1929 Chem. Abstr. Oct. 4703 Extn. of angostura bark with EtOH for 8 days and working up the alkali-sol. portion given galipolin..which gives galipin on methylation. 1939 T. A. Henry Plant Alkaloids (ed. 3) 393 Galipoline..contains two methoxyl groups, and on methylation by diazomethane yields galipine. 1968 I. L. Finar Org. Chem. (ed. 4) II. xiv. 643 A number of alkaloids have been isolated from angostura bark, e.g., cusparine, galipine, galipoline, etc. |
