Resumo: Um extrato metanol-água das folhas de Inga edulis foi fracionado para identificar os compostos polifenólicos. Os compostos identificados foram o acido gálico, a catequina, a epicatequina, a miricetina-3-ramnopiranosídeo, a quercetina-3-glucopiranosídeo e a quercetina-3-ramnopiranosídeo. A capacidade antioxidante do extrato e dos polifenóis puros foi medida pelo teste ORAC e comparada com o teor em fenólicos totais (TP). O extrato bruto seco apresentou valores de ORAC (11.16 mmol TE per g) e TP (496.5 mg GAE per g) muito altos. Os compostos identificados foram responsáveis, respectivamente, por 9.53 % e 12.10 % dos valores ORAC e de TP do extrato de folhas de Inga edulis.

The identified compounds were gallic acid, catechin, epicatechin, myricetin-3-rhamnopyranoside, quercetin-3-glucopyranoside and quercetin-3-rhamnopyranoside. The antioxidant activity of the extract and of pure polyphenols was measured by the ORAC assay and compared with the Total Phenolic (TP) content. The dry crude extract presented very high values for ORAC (11.16 mmol TE per g) and TP (496.5 mg GAE per g). The identified compounds were responsible for 9.53 % and 12.10 % of the ORAC value and TP content of the Inga edulis leaf extract, respectively.engAtividade antioxidanteInga edulisCompostos polifenólicosTeste ORACIdentification and antioxidant activity of several flavonoids of Inga edulis leavesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleSOUZA, Jesus Nazareno Silva deSILVA, Evaldo Martins daSILVA, Milton Nascimento daARRUDA, Mara Silvia PinheiroLARONDELLE, YvanROGEZ, Hervé Louis Ghislaininfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPAinstname:Universidade Federal do Pará (UFPA)instacron:UFPAORIGINALArtigo_IdentificationAntioxidantActivity.pdfArtigo_IdentificationAntioxidantActivity.pdfapplication/pdf387995http://repositorio.ufpa.br/oai/bitstream/2011/6973/1/Artigo_IdentificationAntioxidantActivity.pdf7b010d5c2b6f41c4a30add0cee157131MD51CC-LICENSElicense_urllicense_urltext/plain; charset=utf-849http://repositorio.ufpa.br/oai/bitstream/2011/6973/2/license_url4afdbb8c545fd630ea7db775da747b2fMD52license_textlicense_texttext/html; charset=utf-821328http://repositorio.ufpa.br/oai/bitstream/2011/6973/3/license_text1ddceb2a2635a9472b3c10d731d0906eMD53license_rdflicense_rdfapplication/rdf+xml; charset=utf-822190http://repositorio.ufpa.br/oai/bitstream/2011/6973/4/license_rdf19e8a2b57ef43c09f4d7071d2153c97dMD54LICENSElicense.txtlicense.txttext/plain; charset=utf-81703http://repositorio.ufpa.br/oai/bitstream/2011/6973/5/license.txta12ee01655d4f43dacf016d5e6168febMD55TEXTArtigo_IdentificationAntioxidantActivity.pdf.txtArtigo_IdentificationAntioxidantActivity.pdf.txtExtracted texttext/plain22857http://repositorio.ufpa.br/oai/bitstream/2011/6973/6/Artigo_IdentificationAntioxidantActivity.pdf.txt30a4b0c7cc7e8b1e8e56d7412567f99aMD562011/69732018-02-21 13:42:50.923oai:repositorio.ufpa.br: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Repositório InstitucionalPUBhttp://repositorio.ufpa.br/oai/requestriufpabc@ufpa.bropendoar:21232018-02-21T16:42:50Repositório Institucional da UFPA - Universidade Federal do Pará (UFPA)false
