Description:
Three new C 20 -diterpenoid alkaloids, along with twenty-two known alkaloids, were isolated from the whole herbs of Delphinium tatsienense. The new alkaloids include a vakognavine-type C 20 -diterpenoid alkaloid, designated as tatsienenseine A ( 1 ), and two hetisine-type C 20 -diterpenoid alkaloids, designated as tatsienenseines B ( 2 ) and C ( 3 ). Their structures were elucidated by IR, HR-ESI-MS, 1D- and 2D-NMR analyses.
