Resumo: | In this study, we investigated the in vitro activity against Fusarium proliferatum, chemical characteristics, and antioxidant potential of eight propolis ethanolic extracts (PEE) from Brazil-six from the northern region of the state of Mato Grosso (PEE-1 to PEE-4, PEE-6, and PEE-7), one from the state of Bahia (PEE-5), and the green propolis from Minas Gerais state (PEE-8). The percentage of mycelial growth inhibition (PMGI), and macroconidia and microconidia sporulation of Fusarium proliferatum of these PEEs were evaluated and compared with that of the control (ethanol 70%). The 2% concentrations of PEE-4 to PEE-8 showed significant PMGI in relation to the control. PEE-8 at 2% stood out with the highest PMGI of Fusarium proliferatum and highest antioxidant potential. Among the PEEs that exhibited a significant antifungal action, PEE-8 and PEE-4 presented the highest total flavonoid content and PEE-6 stood out with the highest total phenolic content. Except PEE-1, all the extracts tested showed a reduction of more than 70% in the sporulation of macroconidia PEE-4 and PEE-8 presented predominance of quercetin and kaempferol flavonoids and PEE-6 of caffeic acid. Therefore, the presence of these antioxidant compounds may have contributed to the antifungal activity of these extracts. |

Foi avaliado o efeito dos EEP na percentagem de inibição do crescimento micelial (PIC) e na esporulação de macroconídios e microconídios de Fusarium proliferatum e comparado com o controle (etanol 70%). Os extratos EEP-4 até EEP-8 a 2% apresentaram PIC significativos em relação ao controle O EEP-8 a 2% se destacou com o mais alto PIC de Fusarium proliferatum e o maior potencial antioxidante. De entre os EEP que apresentaram ação antifúngica significativa os EEP-8 e EEP-4 apresentaram os maiores teores de flavonoides totais e o EEP-6 destacou-se com os teores superiores de fenólicos totais. Todos os EEP investigados, exceto o EEP1, provocaram redução de mais de 70% na esporulação de macroconídios. Os EEP-4 e EEP-8 apresentaram predominância dos flavonóides quercitina e campferol e o EEP-6 do ácido cafeico. Estes compostos antioxidantes podem ter contribuído para a atividade antifúngica dos extratos.Sociedade de Ciências Agrárias de Portugal2019-05-10T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/rca.17471eng2183-041X0871-018XGregolin, Fernanda S.Bonaldo, Solange M.Sinhorin, Adilson P.Banderó, Jéfferson L.Wobeto, Carmeninfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-06T09:25:15Zoai:ojs.revistas.rcaap.pt:article/17471Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:31:18.837823Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
