Three New C19-Diterpenoid Alkaloids from Aconitum forrestii

摘要

Afurther study of the alkaloid constituents of Aconitum forrestii led to the isolation of three new C_(19)- diterpenoid alkaloids, named 14-acetoxy-8-O-methylsachaconitine (1), 14-acetoxyscaconine (2), and 8- O-ethylcammaconine (3). Their structures were determined by UV, IR, and MS, 1D- and 2D-NMR analyses.
