A new C19-diterpenoid alkaloid from the roots of Aconitum duclouxii

摘要

A new C19-diterpenoid alkaloid, ducloudine F (1), was obtained from the roots of Aconitum duclouxii, along with eight known alkaloids (2-9) isolated from this species for the first time. Their structures were established on the basis of extensive spectroscopic analyses. The antimicrobial activities of these compounds were investigated.
