From aerial parts of Aconitum napellus L. s. str. (syn. A. anglicum Stapf) were isolated two new diterpenoid alkaloids, 8-O-ethylbenzoylaconine (1) and 15-acetyl-13-dehydracardiopetamine (3), besides cardiopetamine (5), 15-acetylcardiopetamine (4), songoramine (6), and songorine (7). The structures were established by 1H - and 13C-nmr and confirmed by partial synthesis.
