Resumo: From the ethanolic extract of the trunk wood of Tovomita pyrifolium P1. et Tr., family Guttiferae, have been isolated six xanthones: tovopyrifolin B (1), osajaxanthone (2), tovopyrifolin A (3), tovopyrifolin D (4), tovophyllin B (5) and tovophyllin A (9); one pentacyclic triterpene: betulinic acid (6); and one mixture of two steroids: sitosterol (7) and stigmasterol (8). Chromatographic methods were used in the separations of the substances. The structures were elucidated on the basis of the interpretation of the spectral data of the compounds and of their derivatives obtained by acetylation and methylation. A review of xanthones that have been reported was discussed. The biogenetic study of xanthones was considered.

M?todos cromatogr?ficos foram utilizados no trabalho de isolamento das subst?ncias. As estruturas foram elucidadas com base na interpreta??o de dados espectrais das subst?ncias e de seus derivados obtidos por acetila??o e metila??o. Uma revis?o das xantonas descritas na literatura serviu de apoio para o estabelecimento das estruturas das xantonas estudadas. Considera??es sobre a origem biogen?tica das xantonas foram descritas.Submitted by Jorge Silva (jorgelmsilva@ufrrj.br) on 2021-01-26T00:47:02Z No. of bitstreams: 1 1982 - Solange Barbosa da Silva Costa.pdf: 3730732 bytes, checksum: 4ef4065665049c5ff479ac4060ada34d (MD5)Made available in DSpace on 2021-01-26T00:47:02Z (GMT).
