New Diterpenoid Alkaloids from Aconitum liangshanicum

摘要

One new C₁₉-diterpenoid alkaloid, named liangshantine (1), and three new C₂₀-diterpenoid alkaloids, liangshansines A–C (2–4, resp.), as well as eight known compounds, were isolated from the roots of Aconitum liangshanicum. The structures of these new alkaloids were elucidated by spectroscopic methods.
