β¦ Synopsis
Three new diterpenoid alkaloids, along with eleven known alkaloids, were isolated from the whole herbs of Delphinium yunnanense. The new alkaloids include a rearranged-type C 19 -diterpenoid alkaloid, named yunnanenseine A (1), and two hetisine-type C 20 -diterpenoid alkaloids, named yunnanenseine B and C (2 and 3, resp.). Their structures were elucidated by detailed NMR-spectroscopic studies.
