Three new C_(20)-diterpenoid alkaloids,designated as anthriscifolmines A-C(1-3),together with two known alkaloids denudatine and delgramine,were isolated from the whole herb of Delphinium anthriscifolium var.savatieri.The structures of these new alkaloids were elucidated on the basis of spectral data.
