Abstract
Four new alkaloids, alstiphyllanines A-D (1-4), were isolated from Alstonia macrophylla, and their structures were determined by MS and 2D NMR analyses. Alkaloids 1-4 showed moderate antiplasmodial activity against Plasmodium falciparum and vasorelaxant activity against phenylephrine-induced contraction of isolated rat aorta.Entities:
