Abstract 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.
