Description
Also present in the roots of Pleiocarpa rnutica Benth., this alkaloid yields colour-less crystals when recrystallized from EtOH. It is strongly laevorotatory with [α]24D - 151° (c 1.39, CHC13). Two methoxycarbonyl groups are present in the molecule and the base furnishes a crystalline hydrochloride, m.p. 234-5°C (dec.); a perchlorate, m.p. 264-5°C (dec.) and the picrate, m.p. 199-200°C (dec.).
