From the aerial parts of Delphinium crispulum five known norditerpenoid alk
aloids, deltatsine, browniine, karakoline, ezochasmanine and isotalatizidin
e, and the C-20 alkaloid hetisine as well as two new compounds, crispulidin
e and delphicrispuline, were isolated. Structures of the newly isolated all
kaloids were established by spectroscopic methods. (C) 1998 Elsevier Scienc
