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.

The most abundant readily isolated alkaloids of the aerial portion of Aconitum columbianum Nutt. were found to be talatisamine and cammaconine.New spectral data for known derivatives of these alkaloids and descriptions of new derivatives are presented.Less abundant alkaloids identified included the known ones sachaconitine, talatizidine, isotalatizidine, and 14-O-acetyltalatisamine, and the new ones 8-O-methyltalatisamine and a tetrahydroxymonomethoxy alkaloid, columbianine, with the same oxygenation pattern and stereochemistry as cammaconine.
