Abstract

Three new ervatamine-type indole alkaloids, 6-oxo-16,20-episilicine (1), 16,20-episilicine (2), and 6,16-didehydro-20-episilicine (6), along with seven known alkaloids, were isolated from the whole plants of Ervatamia officinalis. Their structures were elucidated by spectroscopic methods. © 2005 Verlag Helvetica Chimica Acta AG.
