Three new monoterpenoid indole alkaloids, (14a,15a)-14,15-epoxyaspidofractinine (1) and maireines A and B (2 and 3, resp.), together with 19 known alkaloids, were isolated from the leaves and twigs of Alstonia mairei. The structures of the new compounds were elucidated by 1D-and 2D-NMR spectroscopic
