The combined alkaloids of the epigeal part and roots of Delphinium biternatum have been investigated. From the epigeal part, in addition to the iliensine detected previously, acomonine, browniine, dehydrobrowniine, delphatine, anthranoyllycoctonine, and three new bases for which the structures of 10-dehydroiliensine, 10-benzoyliliensine, and 10-benzoylbrowniine have been established, have been isolated. From the roots have been isolated browniine, delphatine, and a new base, delbiterine. A lycoctonine skeleton has been established for delbiterine and the positions of the substituting groups have been determined. © 1978 Plenum Publishing Corporation.
