Two new C₁₉-diterpenoid alkaloids from Aconitum straminiflorum

Abstract

Two new C₁₉-diterpenoid alkaloids, straconitines A (1) and B (2), were isolated from the roots of Aconitum straminiflorum. Their structures were elucidated as 14-benzoylducloudine D (1) and 6-hydroxy-14-benzoylducloudine D (2) based on spectroscopic analysis, including IR, ESI-MS, HR-ESI-MS, 1D, and 2D NMR.
