Abstract

Three new C19-diterpenoid alkaloids have been isolated from Delphinium occidentale S. Wats.: occidentaline (16), occidentalidine (17) and 6-acetyldelpheline (18). Structures were deduced by speotroscopic methods and chemical correlations. Twelve known C19- and two C20-diterpenoid alkaloids were also isolated. © 1988.
