Beschreibung

This alkaloid also occurs in the leaves of Uncaria gambier and forms colourless crystals from MeOH. It is, unlike the remaining alkaloids, dextrorotatory with [α]²⁰_D + 160° (MeOH) but the ultraviolet spectrum in EtOH is almost identical with those of the preceding bases, having absorption maxima at 226 and 292 ITIJ1 with a shoulder at 287 mfl. On catalytic hydrogenation it gives the dihydro derivative, m.p. 225-230°C.
