Acesso em: 19 fev. 2015.1678-7064http://www.repositorio.ufop.br/handle/123456789/5243This review gives information on the chemical study of 71 pentaoxygenated, 11 hexaoxygenated and 9 dimeric and more complex xanthones naturally occurring in 7 families, 29 genus and 62 species of higher plants, and 11 described as fern and fungal metabolites. The value of these groups of substances in the connection with the pharmacological activity and the therapeutic use of some species is shown. The structural formulas of 23 isolated compounds and their distribution in the species studied are given.en-USXanthonPentaoxygenated xanthonesHexaoxygenated xanthonesDimeric xanthonesPharmacological activityNaturally occurring pentaoxygenated, hexaoxygenated and dimeric xanthones : a literature survey.Artigo publicado em periodicoA Sociedade Brasileira de Química dá permissão à UFOP para reproduzir no RI/UFOP, uma cópia em formato eletrônico dos artigos completos, sem nenhuma edição e/ou modificação, publicados na revista Química Nova, que tenham como autores seus alunos e/ou professores.
