Diterpenoid alkaloids from the aerial parts of Aconitum anthora L.

Abstract

Isolation and identification of six diterpenoid alkaloids, from Aconitum anthora L. are described. All. proton detected 2D NMR techniques have been used for unambiguous H-1 and C-13 chemical shift assignments of guan-fu-base-Y (6). This is the first investigation of the diterpenoid alkaloids of this plant species.
