Abstract

A comprehensive study of the basic components of Delphinium glaucescens, a toxic larkspur indigenous to the western United States, has led to the isolation of five new Clg- diterpenoid alkaloids and nine known alkaloids. The known alkaloids, listed in order of decreasing abundance, are lycoctonine (16), dictyocarpine (2), browniine (9), 14- dehydrobrowniine (8), methyllycaconitine (12), delcosine (15), dictyocarpinine (7), ...
