Five new norditerpenoid alkaloids, 14-O-benzoylperegrine, 14-O-acetylp
eregrine, munzinanone, munzianine and 10-hydroxyperegrine, together wi
th peregrine and 14-O-methylperegrine, were isolated from Delphinium m
unzianum. The structures of the new alkaloids were elucidated mainly b
y NMR spectroscopy, including 2-D techniques, and partial synthesis st
arting from peregrine.
