Abstract

Two new norditerpenoid alkaloids, hemsleyanidine (1) and isohemsleyanidine (2), have been isolated from the roots of Aconitum hemsleyanum var. circinatum, along with a known compound talatizamine. The structures of the new compounds were established by chemical and spectroscopic methods (including 1H-, 13C-, and 2-D nmr techniques).
