Abstract

Five new C~19~‐diterpenoid alkaloids, named hemsleyaconitines A–E (1–5, resp.), were isolated from Aconitum hemsleyanum Pritz. By UV, IR, MS, 1D‐ and 2D‐NMR analyses, their structures were elucidated as 18‐dehydroxygeniculatine D (1), 6‐hydroxy‐14‐O‐veratroylneoline (2), 14‐O‐acetyl‐8‐ethoxysachaconitine (3), 18‐veratroylkaracoline (4) and 8‐O‐ethylaustroconitine B (5).
