Description and Uses
This carboline alkaloid has been obtained from Lochnera rosea and is also present in curare (Strychnos toxifera). Early preparations have been designated Alkaloid 'C' and C-Alkaloid T. It has [α]D + 56° (pyridine) or + n° (EtOH) and forms a crystalline picrate with a double melting point of 177-9°C and 243-5°C (dec.). The methiodide is identical with lochneram iodide, m.p. 235-8°C. A characteristic p-toluenesulphonyl derivative has been prepared, m.p. 153-4°C. One primary alcoholic hydroxyl is present and the alkaloid yields the O-acetate as colourless needles, m.p. 243°C; [α]D - 5.6° ± 3.0° (c 0.36, pyridine). The structure is that of O-methylsarpagine.
