Abstract

Twelve alkaloids have been isolated from bulbs of Brunsvigia orientalis. 1-Epibowdensine, 1-epidemethoxybowdensine and 1-epidecacetylbowdensine are reported here for the first time. The structure and stereochemistry of these new alkaloids have been determined by physical and spectroscopic methods. The ¹H and ¹³C NMR spectra of 6-hydroxycrinamine (both epimers) and crinamidine were completely assigned by means of 2D NMR techniques.
