title: 13-O-acetylvakhmatine, a new diterpenoid alkaloid from the seeds of Consolida ambigua.
abstract: Vakhmatine [1] and the new diterpenoid alkaloid 13-O-acetylvakhmatine [3] have been isolated from the polar alkaloidal fractions of the seeds of Consolida ambigua, together with ajacine, delcosine, gigactonine, and takaosomine. Structure 3 has been established on the basis of spectroscopic data and chemical correlation with 1.
