title: New Alkaloids from Aconitum stapfianum.
abstract: Nineteen alkaloids, including a new C19-diterpenoid alkaloid stapfianine A (1) and a new benzamide derivative stapfianine B (2) were isolated from the roots of Aconitum stapfianum. Their structures were established on the basis of extensive spectroscopic analyses (IR, HRESIMS, 1D and 2D NMR).
