Journal ArticleDOI
Phenolics: From Chemistry to Biology
TL;DR: Phenolics and polyphenols as discussed by the authors have received increasing interest in phenolics' biological activities, and several works addressing this matter are referred in this special issue of Molecules.
Journal ArticleDOI
Phenolic compounds and antimicrobial activity of olive (Olea europaea L. Cv. Cobrançosa) leaves.
Ana Paula Esteves Pereira,Isabel C.F.R. Ferreira,Filipa Marcelino,Patrícia Valentão,Paula B. Andrade,Rosa M. Seabra,Leticia M. Estevinho,Albino Bento,José Alberto Pereira +8 more
TL;DR: At low concentrations olive leaves extracts showed an unusual combined antibacterial and antifungal action, which suggest their great potential as nutraceuticals, particularly as a source of phenolic compounds.
Journal ArticleDOI
Walnut (juglans regia l.) leaves: phenolic compounds, antibacterial activity and antioxidant potential of different cultivars
José Alberto Pereira,Ivo Oliveira,Anabela Sousa,Patrícia Valentão,Paula B. Andrade,Isabel C.F.R. Ferreira,Federico Ferreres,Albino Bento,Rosa M. Seabra,Leticia M. Estevinho +9 more
TL;DR: Walnut leaves selectively inhibited the growth of Gram positive bacteria, being B. cereus the most susceptible one and Lara the most effective one, and all of the studied walnut leaves cultivars presented high antioxidant activity.
Journal ArticleDOI
Quince (Cydonia oblonga Miller) fruit (pulp, peel, and seed) and jam: Antioxidant activity
Branca M. Silva,Paula B. Andrade,Patrícia Valentão,Federico Ferreres,Rosa M. Seabra,Margarida A. Ferreira +5 more
TL;DR: The evaluation of the antioxidant activity of methanolic extracts showed that peel extract was the one presenting the highest antioxidant capacity, which seems to indicate that the phenolic fraction gives a higher contribution for the antioxidant potential of quince fruit and jam.
Journal ArticleDOI
Phenolic profiles of Portuguese olive fruits (Olea europaea L.): Influences of cultivar and geographical origin
Ana Ferreira da Vinha,Federico Ferreres,Branca M. Silva,Patrícia Valentão,Ana Cristina Gonçalves,José Alberto Pereira,M. Beatriz P.P. Oliveira,Rosa M. Seabra,Paula B. Andrade +8 more
TL;DR: In this paper, the phenolic compounds present in 29 samples of olive fruits were analysed by reversed-phase HPLC/DAD and/or HPLC-DAD/ESI-MS/MS.
