Mediterranean non-cultivated vegetables as dietary sources of compounds with an...
Morales, Patricia; Ferreira, Isabel C.F.R.; Carvalho, Ana Maria; Sánchez Mata, María de Cortés; Cámara Hurtado, Montaña; Fernández-Ruiz, VirginiaNon-cultivated vegetables whose basal leaves have been traditionally consumed in Spain were evaluated for their potential in human nutrition, considering vitamin C, organic acids, tocopherols, phenolics and flavonoids, and antioxidant activity. As far as we know, this is the first report on organic acids and vitamin C of Anchusa azurea and Apium nodiflorum, on tocopherols of Anchusa azurea, Beta vulgaris, Chond...
Exploring the antioxidant potential of Helichrysum stoechas (L.) Moench phenoli...
Barroso, Marisa; Barros, Lillian; Dueñas, Montserrat; Carvalho, Ana Maria; Santos-Buelga, Celestino; Fernandes, Isabel P.; Barreiro, M.F.The present work explores the antioxidant potential of Helichrysum stoechas (L.) Moench phenoliccompounds for cosmetic applications involving the following steps: chemical characterization, microen-capsulation and incorporation into a moisturizer. Eighteen different phenolic compounds were identifiedin flowering aerial parts (decoction and hydroalcoholic extract), being 3,5-O-dicaffeoylquinic acid andmyricetin ...
Bioactivity of different enriched phenolic extracts of wild fruits from Northea...
Guimarães, Rafaela; Barros, Lillian; Calhelha, Ricardo C.; Carvalho, Ana Maria; Queiroz, Maria João R.P.; Ferreira, Isabel C.F.R.Arbutus unedo, Prunus spinosa, Rosa micrantha and Rosa canina are good sources of phenolic compounds, including anthocyanins. These compounds have potent antioxidant properties, which have been related to anticancer activity. Herein, the in vitro antioxidant and antitumor properties of enriched phenolic extracts (non-anthocyanin phenolic compounds enriched extract- PE and anthocyanins enriched extract- AE) of t...
Nutrients, phytochemicals and antioxidant activity in wild populations of Alliu...
García-Herrera, Patricia; Morales, Patricia; Fernández-Ruiz, Virginia; Sánchez-Mata, M.C; Cámara Hurtado, Montaña; Carvalho, Ana MariaWild Allium species with a long tradition of use, such as Allium ampeloprasum L. could provide interesting bioactive compounds to current diet. The nutrient and bioactive compound content of this wild vegetable has been scarcely known. Therefore, the aim of this work is to provide a detailed chemical quantification of nutrients, hydrophilic and lipophilic bioactive compounds and the antioxidant capacity of the ...
Antibacterial potential of Northeastern Portugal wild plant extracts and respec...
Pinho, Eva; Ferreira, Isabel C.F.R.; Barros, Lillian; Carvalho, Ana Maria; Soares, Graça; Henriques, MarianaThe present work aims to assess the antibacterial potential of phenolic extracts, recovered from plants obtained on the North East of Portugal, and of their phenolic compounds (ellagic, caffeic, and gallic acids, quercetin, kaempferol, and rutin), against bacteria commonly found on skin infections. The disk diffusion and the susceptibility assays were used to identify the most active extracts and phenolic compo...
Pterospartum tridentatum, Gomphrena globosa and Cymbopogon citratus: a phytoche...
Roriz, Custódio Lobo; Barros, Lillian; Carvalho, Ana Maria; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.Pterospartum tridentatum (L.) Willk., Gomphrena globosa L. and Cymbopogon citratus (DC) Stapf. are examples of medicinal plants that demand a more detailed characterization. Therefore, phenolic composition (e.g., phenolic acids and flavonoids) was analyzed by chromatographic and mass spectrometry techniques and the antioxidant activity was also accessed through free radicals scavenging activity, reducing power ...
Flower extracts of Filipendula ulmaria (L.) Maxim inhibit the proliferation of ...
Lima, M. João; Sousa, Diana; Lima, Raquel T.; Carvalho, Ana Maria; Ferreira, Isabel C.F.R.; Vasconcelos, M. HelenaFilipendula ulmaria (L.) Maxim (meadowsweet) is a popular medicinal species that can be found throughout most Europe and Asia. The plant is known for its rich antioxidants content, having compounds such as flavonoids and ascorbic acid. Therefore, the aim of this work was to investigate if the flower extracts of F. ulmaria (L.) Maxim have cell growth inhibitory activity in three human tumour cell lines represent...
Phenolic extracts of Rubus ulmifolius Schoot flowers: characterization, microen...
Martins, Ana; Barros, Lillian; Carvalho, Ana Maria; Santos-Buelga, Celestino; Fernandes, Isabel P.; Barreiro, Filomena; Ferreira, Isabel C.F.R.Rubus ulmifolius Schott (Rosaceae), known as wild blackberry, is a perennial shrub found in wild and cultivated habitats in Europe, Asia and North Africa. Traditionally, it is used for homemade remedies because of its medicinal properties, including antioxidant activity. In the present work, phenolic extracts of R. ulmifolius flower buds obtained by decoction and hydroalcoholic extraction were chemically and bi...
O ensino do alemão nos liceus portugueses entre 1926 e 1949
Carvalho, Ana Maria MarquesO presente trabalho tem como tema o ensino do Alemão nos liceus portugueses, num período extremamente conturbado e controverso da história da Alemanha e de Portugal, nomeadamente o tempo do Terceiro Reich e dos primeiros anos do Estado Novo. Este estudo, que partiu da pesquisa, consulta, seleção e posterior análise crítica de legislação e de publicações periódicas da época, debruça-se sobre as reformas do siste...
Antifungal activity and detailed chemical characterization of Cistus ladanifer ...
Barros, Lillian; Alves, Carlos; Duenas, M.; Silva, Sónia Carina; Carvalho, Ana Maria; Henriques, Mariana; Santos-Buelga, CelestinoThe 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 phenolicextract...
