Three new norditerpenoid alkaloids, dehydrobicoloridine, bicoloridine
alcohol and peregrinine, together with the known alkaloids 14-O-acetyl
peregrine, peregrine alcohol, peregrine, bicoloridine, nudicaulidine,
dihydrogadesine, hetisinone, hetisine and atisinium chloride were isol
ated from Delphinium pereginum var. elongatum. The structures of the n
ew alkaloids were determined by NMR spectroscopy and partial synthesis
.
