• Description: The root bark of Hunteria urnbellata (K. Schum) Hall yields this alkaloid which forms colourless needles from EtOH and has a specific rotation of [α]D - 217° (c 0.45, CHCl). The ultraviolet spectrum in EtOH has absorption maxima at 230-4, and 295 nm, shoulders at 276 and 299 nm and inflexions at 248 and 288 nm. The O-acetate gives an ultraviolet spectrum with absorption maxima at 230, 285, 289 and 293 nm with an inflexion at 251 nm. The base has also been characterized as the methyl ether, m.p. 250°C (dec.) when crystallized from MeOH-CHC13 , giving an ultraviolet spectrum in EtOH with absorption maxima at 230 and 294 nm and an inflexion at 250 nm. Thermolysis of the alkaloid furnishes eburnamenine.
