Resumo: | Dois novos e incomuns derivados de epicatequina e epiafzelequina contendo unidades feniloctanóides glicosiladas e denominados mascagninas A e B foram isolados, juntamente com quercetina-3-O-α-L-ramnopiranosil-(1→6)-β-D-glucopiranosídeo, das partes aéreas de Mascagnia pubiflora(Malpighiaceae), uma planta tóxica para o gado. Suas estruturas foram determinadas pela combinação de espectroscopia de ressonância magnética nuclear (RMN) uni e bidimensionais e dados de espectroscopia de massas (MS). |

Their structures were established by a combination of 1D- and 2D-nuclear magnetic resonance spectroscopic techniques and mass spectrometry data.engJournal of the Brazilian Chemical SocietyMalpighiaceaeBotânica - químicaPlantas TóxicasBotany - chemistryPlants, ToxicTwo unusual epicatechin and epiafzelechin derivatives from Mascagnia pubiflora, a plant toxic to cattleinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleGarcez, Walmir SilvaGarcez, Fernanda RodriguesZanella, Deizeluci Pereira de FátimaHamerski, LidilhoneFerreira, Antonio GilbertoBarison, AnderssonAbot, Alfredo Raúlinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMSinstname:Universidade Federal de Mato Grosso do Sul (UFMS)instacron:UFMSTHUMBNAILTwo unusual epicatechin and epiafzelechin.pdf.jpgTwo unusual epicatechin and epiafzelechin.pdf.jpgGenerated Thumbnailimage/jpeg1648https://repositorio.ufms.br/bitstream/123456789/1197/4/Two%20unusual%20epicatechin%20and%20epiafzelechin.pdf.jpg8c358b960ac87b3c608c5209094c6201MD54ORIGINALTwo unusual epicatechin and epiafzelechin.pdfTwo unusual epicatechin and epiafzelechin.pdfapplication/pdf2167012https://repositorio.ufms.br/bitstream/123456789/1197/1/Two%20unusual%20epicatechin%20and%20epiafzelechin.pdf378a6db66966715119b16514bed65a5dMD51LICENSElicense.txtlicense.txttext/plain; charset=utf-81748https://repositorio.ufms.br/bitstream/123456789/1197/2/license.txt8a4605be74aa9ea9d79846c1fba20a33MD52TEXTTwo unusual epicatechin and epiafzelechin.pdf.txtTwo unusual epicatechin and epiafzelechin.pdf.txtExtracted texttext/plain27711https://repositorio.ufms.br/bitstream/123456789/1197/3/Two%20unusual%20epicatechin%20and%20epiafzelechin.pdf.txt364dd471646a5300e8addbca4a3727c6MD53123456789/11972021-09-30 15:55:48.51oai:repositorio.ufms.br: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Repositório InstitucionalPUBhttps://repositorio.ufms.br/oai/requestri.prograd@ufms.bropendoar:21242021-09-30T19:55:48Repositório Institucional da UFMS - Universidade Federal de Mato Grosso do Sul (UFMS)false |
