| Abstract
| - Three new diterpenoid alkaloids, isoazitine (1), 19-oxodihydroatisine (2), and 22-O-acetyl-19-oxodihydroatisine (3), and eight known alkaloidsazitine (4), dihydroatisine (5), delphinine, neoline, bullatine C(14-acetylneoline), chasmanine, 14-acetylchasmanine, and the quaternary base atisinium chloride (7)were isolated from the aerial parts of Delphinium staphisagria. Structures of the new alkaloids wereestablished mainly by 1D and 2D NMR spectroscopy, including 1H COSY, HMQC, HMBC, and ROESY.The 1H and 13C NMR data for alkaloids 4 and 5 are also reported.
