摘要：Resumo A madeira de tronco da Tovomita brasiliensis Walp. (Guttiferae) contém 1,5-dihidroxi-6,7-dimetoxixantona, ácido betulínico e sitosterol. O isolamento concomitante de três policetídeos revelou a provável infestação da amostra analisada por fungos.
其他摘要：Summary The trunk wood of Tovomita brasiliensis Walp. from Belém, Pará State, contains 1,5-dihydroxy-6.7-dimethoxyxanthone, betulinic acid and sitosterol. The additional presence of 8-hydroxy-3,5-dimethyl-3.4-dihydroisocoumarin, 8-hydroxy-5-methoxy-3-methyl-3,4-dihydroisocoumarin and 7-chloro-8-hydroxy-6-methoxy-3-methylisocoumarin in the benzene extract is most probably due to infestation of the plant material by fungi.
