From the roots and epigeal part of Delphinium dictyocarpum from two growth sites have been isolated methyllycaconitine, eldeline, eldelidine, lycoctonine, the new base dictyocarpine, and bases (II) and (III). The lycoctonine skeleton has been proposed for dictyocarpine and the positions of the substituting groups have been suggested. © 1974 Consultants Bureau, a division of Plenum Publishing Corporation.
