Diterpenoid Alkaloids from Delphinium tatsienense

Three new C20‐diterpenoid alkaloids, along with twenty‐two known alkaloids, were isolated from the whole herbs of Delphinium tatsienense. The new alkaloids include a vakognavine‐type C20‐diterpenoid alkaloid, designated as tatsienenseine A (1), and two hetisine‐type C20‐diterpenoid alkaloids, design...

Description
Summary:Three new C20‐diterpenoid alkaloids, along with twenty‐two known alkaloids, were isolated from the whole herbs of Delphinium tatsienense. The new alkaloids include a vakognavine‐type C20‐diterpenoid alkaloid, designated as tatsienenseine A (1), and two hetisine‐type C20‐diterpenoid alkaloids, designated as tatsienenseines B (2) and C (3). Their structures were elucidated by IR, HR‐ESI‐MS, 1D‐ and 2D‐NMR analyses.
