title: Three new C19-diterpenoid alkaloids from Delphinium giraldii.
abstract: Further investigation of the roots of Delphinium giraldii DIELS led to the isolation of three new C(19)-diterpenoid alkaloids, giraldines G (1), H (2), and I (3). The structures of 1-3 were established based on spectroscopic evidence.
