From the root extracts of Aconitum dolichorhynchum Wang var. subglabratum T. L. Ming, we have isolated five new minor alkaloids: dolichotine A (I), dolichotine B (II), dolichotine C (III), dolichotine D (IV) and dolichotine E (V), besides yuna-conitine (VI), 8-deacetylyunaconitine (VII), crassicauline A (VIII), talatisamine (IX), columbidine (X) and cammaconine (XI). The structures of these alkaloids were determined with the aid of spectral data and correlation with compounds of established structures. The structure of dolichotine C was confirmed by synthesis from talatisamine and partial hydrolysis. All the new alkaloids are characteristic of aromatic acid ester or palmitic acid ester substituted at C8 of C19-diterpenoid alkaloids. © 1989.
