The alkaloidal constituents of Aconitum columbianum Nutt. ssp. columbianum have been investigated.In addition to the known alkaloids cammaconine (12), deltaline (10), dictyocarpine (11), talatizamine (3), and 8-O-methyltalatizamine (7), a new base columbidine (4) has been isolated and its structure elucidated.The structure was derived on the basis of spectral data and chemical correlation with talatizamine.Synthesis of 7 from talatizamine is described and the 13C-nmr spectrum of 14-dehydrotalatizamine has been recorded.Certain 13C-nmr signals for these compounds have been reassigned.
