São espécies nativas e popularmente utilizadas como diuréticas e anti-inflamatórias. As espécies Echinodorus macrophyllus e Echinodorus grandiflorus têm o uso recomendado pela Farmacopeia Brasileira. Entretanto, devido à plasticidade fenotípica do gênero, a identificação precisa é dificultada, consequentemente, Echinodorus floribundus e Echinodorus subalatus têm sido utilizadas pela população para os mesmos fins. O objetivo foi avaliar marcadores químicos para as espécies Echinodorus floribundus e Echinodorus subalatus e a similaridade química dessas com as espécies descritas na Farmacopeia Brasileira. A triagem fitoquímica revelou presença de fenóis, flavonoides, flavonas, flavonóis, xantonas, esteroides e triterpenoides nos extratos. Porém ambas as espécies apresentaram valores inferiores de flavonoides totais quando comparadas com Echinodorus scaber, descrita na literatura. A caracterização do extrato aquoso foliar em cromatografia líquida de alta eficiência (CLAE-DAD) detectou 118 e 121 compostos em E. floribundus e E. subalatus, respectivamente. Destes, 25 apresentaram espectros UV-Vis característicos de compostos fenólicos. Não foram detectados o ácido chicórico e a isoorientina, marcadores comuns em Echinodorus. Os teores de derivados do ácido o-hidroxicinâmico para E. floribundus e E. subalatus (5,52% e 3,07%, respectivamente) foram superiores ao que é exigido pela Farmacopeia Brasileira. Dessa forma, há diferenças químicas entre Echinodorus floribundus e Echinodorus subalatus e as descritas pela Farmacopeia Brasileira, entretanto, há indícios de potencial farmacológico das espécies estudadas.The name “chapéu-de-couro” is given to plants belonging to genus Echinodorus(Alismataceae) These are native and popularly used as diuretic and anti-inflammatory. The species E. macrophyllusand E. grandiflorushave the recommended use by the Brazilian Pharmacopeia. However, due to the phenotypic plasticity of the genus, precise identification is difficult, therefore, E. floribundusand E. subalatus have been used by the population for the same purpose. The aim of the work was to evaluate chemical markers for the species E. floribundusand E. subalatusand their chemical similarity with the species described in the Brazilian Pharmacopeia. Phytochemical screening revealed the presence of phenols, flavonoids, flavones, flavonols, xanthones, steroids and triterpenoids in the extracts. However, both species presented lower values of flavonoids and total phenols when compared with E. scaber. The characterization of aqueous leaf extract in high performance liquid chromatography (HPLC-DAD) detected 118 and 121 compounds in E. floribundusand E. subalatus, respectively. Of these, 25 showed characteristic UV-Vis spectra of phenolic compounds. Markers chicory acid and isoorientin, present in Echinodorus, weren’t detected. The levels of o-hydroxycinnamic acid derivatives for E. floribundus and E. subalatus(5.52% and 3.07%, respectively) were higher than required by the Brazilian Pharmacopeia. Thus, there are chemical differences between Echinodorus floribundusand Echinodorussubalatusand those described by the Brazilian Pharmacopeia, however, there are indications of pharmacological potential of the species studied.FAPEMIG - Fundação de Amparo à Pesquisa do Estado de Minas GeraisCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorporUniversidade Federal de Minas GeraisUFMGBrasilICA - INSTITUTO DE CIÊNCIAS AGRÁRIASScientia PlenaPlantas medicinaisFarmacologiaAgentes antiinflamatóriosFlavonóidesFenóisDiuréticosMarcadores químicos em espécies de Echinodorus (Alismataceae) utilizadas como chapéu-de-couroChemical markers in species of Echinodorus(Alismataceae) used as “chapéu-de-couro”info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.scientiaplena.org.br/sp/article/view/6033Rizia Rodrigues SantosFrancine Souza Alves da FonsecaAlcinei Místico AzevedoErnane Ronie Martinsinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/52129/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALMarcadores químicos em espécies de Echinodorus (Alismataceae) utilizadas como chapéu-de-couro.pdfMarcadores químicos em espécies de Echinodorus (Alismataceae) utilizadas como chapéu-de-couro.pdfapplication/pdf821102https://repositorio.ufmg.br/bitstream/1843/52129/2/Marcadores%20qu%c3%admicos%20em%20esp%c3%a9cies%20de%20Echinodorus%20%28Alismataceae%29%20utilizadas%20como%20chap%c3%a9u-de-couro.pdf236d20dbfffc4dcfde38e0be892be156MD521843/521292023-04-18 16:36:33.666oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-04-18T19:36:33Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
