A norditerpenoid alkaloid, 6-epiforsticine, has been isolated from the roots of the plants Aconitum hemsleyanum var. pengzhouense and A. kuzsnezoffii and its structure has been established as 1 on the basis of 2D-NMR and X-ray diffraction analysis. The structure of forsticine has accordingly been revised from 1 to 2.
