• Beschreibung

  A second alkaloid present in Macrorungia longistrobus C. B. Cl., this base forms light yellow prisms when recrystallized from MeOH. It yields coloured salts and derivatives, e.g. the hydrochloride as orange-red needles, decomposing above 290°C; the perchlorate as light yellow plates from MeOH, also decomposing above 290°C; methiodide, orange prisms from MeOH, decomposing above 290°C and the picrate, yellow needles, decomposing above 250°C. The ultraviolet spectra of the alkaloid have been extensively studied. In neutral solution (EtOH), the absorption maxima are at 220, 284, 301 and 354 mt.!; in acid solution (0.2 N/HCl-EtOH), they occur at 203, 225, 253, 300 and 413 mt.! while in alkaline solution (0.1 N/NaOH-EtOH) they are at 227,283,323 and 382 mt.!. The struc_x0002_ture, as determined from the mass spectrum, is l'-methyl-2:4'-(1'Himidazolyl)quinolin-2' -one.
