Abstract
A new spiro heterocycle, decarboxyportentol acetate (1) was isolated from the barks of Laumoniera bruceadelpha Nooteboom (Simaroubaceae), together with 3,4-dehydrotheaspirone (2), and their structures were elucidated by 2D NMR analysis. 3,4-Dehydrotheaspirone (2) showed potent antiplasmodial activity against Plasmodium falciparum 3D7.
