From the aerial parts of four Delphinium species 11 known and 3 new norditerpenoid alkaloids have been isolated: from D. dissectum Huth: delavaine A/B, deoxylycoctonine, methyllycaconitine; new: 10-hydroxymethyllycaconitine; from D. excelsum Reichenb.: delcaroline, delectinine, delterine, methyllycaconitine; new: 10-hydroxymethyllycaconitine, 18-O-methyldelterine and 10-hydroxynudicaulidine; from D. grandiflorum L.: delcosine, deltatsine, grandiflorine, methyllycaconitine; from D. triste Fisch.: delcosine, macrocentridine, 14-dehydrodelcosine. The structures of the new alkaloids were established on the basis of MS, 1H, 13C, DEPT, homonuclear COSY, HMQC and HMBC NMR spectroscopic techniques.
