Studies on plants containing indole alkaloids. VII. Isolation of several aspidosperma- and vincamine-type alkaloids from the seeds of Amsonia elliptica Roem. et Schult



Chemical and Pharmaceutical Bulletin 26(4): 1182-1187



Four known (tabersonine, tetrahydroalstonine, DELTA 14-vincamine and 16-epi- DELTA 14-vincamine) and 4 new indole alkaloids (3-oxo-tabersonine, 14,15-epoxy-3-oxo-vincadifformine, 16-carbomethoxy-16-hydroxy-14,15-epoxy-3-oxo-1,2-dihydroaspidospermidine and tabersonine N(b)-oxide) were isolated.
