A new norditerpenoid alkaloid, royleinine (1) has been isolated from the aerial parts of Delphinium roylei Munz, along with three more norditerpenoid alkaloids, isotalitazidine, condelphine and senbusine-C. The structure of 1 has been established on the basis of its spectroscopic data (IR, HRMS, 1H, 13C, 1H - 1H and 1H - 13C COSY and NOESY spectra).
