The known alkaloids isotalatisidine, nevadensine, delcosine, delsoline, and isobaldine have been isolated form the epigeal
part ofDelphinium confusum M. Pop., collected in the flowering period, and also a new alkaloid with the composition C24H39NO5, mp 136–137°C (acetone), for which the structure of 14-methylisotalatisidine has been established on the basis of spectral
characteristics and of
