Abstract
A new diterpene alkaloid, deoxyjesaconitine, was isolated from the rhizoma of Aconitum subcuneatum NAKAI (Ranunculaceae) and its structure was established by analysis of the spectral data and by conversion of jesaconitine into deoxyjesaconitine. Deoxyaconitine, hypaconitine, jesaconitine, aconitine, and mesaconitine were also isolated from the same plant.
