The tree bark of Nandina domestica elaborates this alkaloid which forms colourless
crystals from EtOH. The structure has been established from ultraviolet and NMR
spectroscopy, particularly the application of the nuclear Overhauser effect.
Additional confirmation of the above structure has been provided by the synthesis
of the alkaloid by dehydrogenation of O-methyldomesticine.
