Antifungal activity of phenolic compounds identified in flowers from the North ...
Alves, Carlos Tiago; Ferreira, Isabel C.F.R.; Barros, Lillian; Silva, Sónia; Azeredo, Joana; Oliveira, Rosário; Henriques, MarianaTo evaluate the antifungal effect of gallic acid, catechin, luteolin and quercetin, phenolic compounds identified from flowers of North Eastern Portugal, against Candida planktonic and biofilm cells. Materials & methods: The MICs were determined in Candida planktonic cells and the effect of phenolic compounds on Candida biofilms was assessed through quantification of CFUs. Results: MIC values demonstrated that ...
Characterization of phenolic compounds in wild medicinal flowers from Portugal ...
Barros, Lillian; Alves, Carlos Tiago; Dueñas, Montserrat; Silva, Sónia; Oliveira, Rosário; Carvalho, Ana Maria; Henriques, MarianaIn the present work, the phenolic compounds of Castanea sativa, Filipendula ulmaria and Rosa micrantha flowers from Northeastern Portugal were characterized by HPLC-DAD-ESI/MS. Furthermore, it was performed a screening of their antifungal potential against Candida species (C. albicans, C. glabrata, C. parapsilosis and C. tropicalis). C. sativa sample gave the highest amount of phenolic compounds (18973 ± 40 µg...
Antifungal activity and detailed chemical characterization of Cistus ladanifer ...
Barros, Lillian; Dueñas, Montserrat; Alves, Carlos Tiago; Silva, Sónia; Henriques, Mariana; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.The life-threatening mycoses caused by opportunistic fungal pathogens (mainly species from the genus Candida) associated with nosocomial infections, are one of the major health problems in our days. Therefore, it is crucial to identify new compounds, especially natural ones, that are active against the most broaden spectrum of Candida species. Herein, a screening of the antifungal potential of a phenolic extrac...
Cistus ladanifer as a source of phenolic compounds with antifungal activity
Barros, Lillian; Dueñas, Montserrat; Alves, Carlos Tiago; Silva, Sónia; Henriques, Mariana; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.A screening of the antifungal potential of phenolic extract of Cistus ladanifer from Northeast Portugal, against Candida species was performed. The extract was characterized by HPLC-DAD-ESI/MS. Phenolic acids and derivatives, ellagic acid derivatives and flavonoids, such as catechins, flavonols and flavones, were found in the sample. The most abundant group was ellagic acid derivatives in which punicalagin gall...
