Three new norditerpenoid alkaloids, dehydrobicoloridine, bicoloridine alcohol and peregrinine, together with the known alkaloids 14-O-acetylperegrine, peregrine alcohol, peregrine, bicoloridine, nudicaulidine, dihydrogadesine, hetisinone, hetisine and atisinium chloride were isolated from Delphinium pereginum var. elongatum. The structures of the new alkaloids were determined by NMR spectroscopy and partial synthesis. © 1995.
