title: Norditerpene and diterpene alkaloids from Aconitum variegatum.
abstract: Aerial parts of Aconitum variegatum L. from the Pyrenees furnished four norditerpene alkaloids, 16 beta-hydroxycardiopetaline, 8-ethoxysachaconitine, 14-acetylgenicunine B, N-deethyl-N-19-didehydrosachaconitine, five diterpene alkaloids 15-veratroyldictizine, 15-veratroyl-17-acetyldictizine, 15-veratroyl-17-acetyl-19-oxodictizine, N-ethyl-1 alpha-hydroxy-17-veratroyldictizine, variegatine and the known alkaloids sachaconitine, 14-O-acetylsachaconitine, karakoline, talatizamine, 10-hydroxytalatizamine, 14-acetyltalatizamine, 14-acetyl-10-hydroxytalatizamine, N-methylarmepavine, pengshenin B, delsoline, dihydrodelsoline, delcosine and genicunin B. Structures of the alkaloids were established by MS, 1D- and 2D-NMR techniques.
