Abstract

Two new C19-diterpenoid alkaloids, named aconitramines D (1) and E (2), were isolated from the roots of Aconitum transsectum. Based on comprehensive spectroscopic analyses including IR, ESI-MS, HR-ESI-MS, and 1D and 2D NMR, their structures were elucidated as 18-demethoxyltransconitine A (1) and 8-O-anisoyl-14-hydroxylacoforesticine (2).
