RESUMO
From the roots of Delphinium stapeliosum three new norditerpenoid alkaloids, 14-demethyltuguaconitine (1), 14-deacetyl-14-isobutyrylnudicauline (2), and 14-deacetyl-14-isobutyrylajadine (3), and nine known norditerpenoid alkaloids, delbonine (4), methyllycaconitine (5), 14-deacetylnudicauline (6), ajacine (7), deltatsine (8), delcosine (9), 14-deacetylajadine (10), nudicauline (11), and ajadine (12), were isolated. Structure elucidation and identification were based on NMR and mass spectra.
