Together with delcorine, lycoctonine, eldeline, dehydrodelcorine, ilidine, browniine, and dictyocarpinine, we have isolated a new alkaloid, delcoridine, from the epigeal part of Delphinium iliense Huth. Its structure has been established on the basis of the results of a study of the chemical transformations and spectra characteristics. This is the first time that the alkaloid dictyocarpinine has been isolated from this plant. © 1981 Plenum Publishing Corporation.
