Resumo: The subject of free radicals and their effects on biological systems is an important problem in Medicine. Antioxidants can protect biological systems against free radicals. In this study, the effect of methanol ratio (0, 20, 50, 80, and 100%) in water on extraction yield of Total phenolic (TP) compounds and antioxidant activity (AA) of Stachys turcomanica extract were evaluated. The amount of TP compounds were determined using Folin-Ciocalteu reagent, and AA measured by 2, 2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP) and beta-caroten linoleic acid methods. The results showed extraction of phenolic compounds and their AA were affected by solvent combinations. In addition, there was a good correlation between TP content and AA of Stachys turcomanica extracts. Finally the methanol: water (80:20) was good solvent in extracting of phenolic compounds with highest AA.

Os antioxidantes podem proteger os sistemas biológicos contra os radicais livres. Neste estudo, avaliou-se oefeito da proporção de metanol (0, 20, 50, 80 e 100%) na água com o rendimento de extração de compostos fenólicos totais (TP) e atividade antioxidante (AA) do extrato Stachys turcomanica. A quantidade de compostos de TP foi determinada utilizando o reagente de Folin-Ciocalteu, e AA medido por 2, 2-difenil-1-picrilidrazilo (DPPH), poder antioxidante redutor férrico (FRAP) e ácido beta-caroten ácido linoleico. Os resultados mostraram a extração de compostos fenólicos e os seus AA foram afetados por combinações de solventes. Além disso, houve uma boa correlação entre o conteúdo de TP e os extratos de AA de Stachys turcomanica. Finalmente, o metanol: água (80:20) foi bom solvente na extração de compostos fenólicos com AA mais alto.EDUFU2018-10-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4151710.14393/BJ-v34n5a2018-41517Bioscience Journal ; Vol. 34 No. 5 (2018): Sept./Oct.; 1349-1356Bioscience Journal ; v. 34 n. 5 (2018): Sept./Oct.; 1349-13561981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/41517/24293Brazil; ContemporaryCopyright (c) 2018 Khashaiar Namvar, Esmaeil Ataye Salehi, Naeim Mokhtarianhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessNamvar, KhashaiarAtaye Salehi, EsmaeilMokhtarian, Naeim2022-02-10T16:28:34Zoai:ojs.www.seer.ufu.br:article/41517Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-10T16:28:34Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
