Chemical investigation of the aerial parts of Delphinium barbeyi resulted in the isolation of three new alkaloids, 14-acetyldictyocarpine, barbinine and barbinidine, as well as 13 known alkaloids. Structures and stereochemistry were deduced by spectroscopic methods. The structures of 14-acetyldictyocarpine and barbinidine were confirmed by chemical correlation with dictyocarpine. © 1989.
