RESUMO
Three new cadinane- and guaiane-type sesquiterpenoids, 2-hydroxy-10-epi-zonarene 1, 2, 15-dihydroxycalamenene 2 and guaia-4, 6-dien-3-one 3, were isolated from the wood of Enterospermum madagascariensis (Rubiaceae) grown in Madagascar. Their structures were established from concerted application of 2D NMR techniques including gs-COSY, gs-HMQC, gs-HMBC and NOESY.
