From the aerial parts of Delphinium uncinatum a new diterpenoid uncinatine and four known norditerpenoid alkaloids have been isolated. By spectral data (1H and 13C NMR) the known compounds were established as 14- acetylperegrine, 14-acetylvirescenine, condelphine and delbrusine. The structure of the new alkaloid was deduced by 1D and 2D NMR techniques.
