title: C20-diterpenoid alkaloids from Delphinium trifoliolatum.
abstract: Three new C20-diterpenoid alkaloids, trifoliolasines D-F (1-3), were isolated from the aerial parts of Delphinium trifoliolatum, and their structures were determined by the interpretation of spectroscopic data and by the single-crystal X-ray crystallographic analysis of 1.
