Description
Summary:From the bulbs of Brunsvigia josephinae (Amaryllidaceae), crinine, buphanisine, buphanidrine, undulatine, 11- O-acetylambelline, brunsbelline and hippadine have been isolated and identified. 11- O-Acetylambelline and brunsbelline are reported here for the first time. The structure and stereochemistry of the new alkaloids have been determined by spectroscopic analyses and by the application of 2D NMR techniques. 1H and 13C NMR spectra of crinine, buphanisine, buphanidrine and undulatine have now been completely characterized.
