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).

Keywords: Aconitum stapfianum; Benzamide; Diterpenoid alkaloid; Ranunculaceae; Stapfianine.
