This alkaloid has been isolated from Decodon verticillatus L. and forms colourless crystals from a mixture of MeOH and CHCl3. It has [α]D + 39° (c 0.95, CHCl3) and gives an ultraviolet spectrum with absorption maxima at 260 and 285 mJ.1. The acetyl derivative crystallizes from Et20 with m.p. 183-5°C; [α]D - 92.7° (c 0.96, CHCl3). Catalytic hydrogenation yields Decamine (q.v.).
