Nutritional composition, antioxidant activity and phenolic compounds of wild Ta...
Dias, Maria Inês; Barros, Lillian; Alves, Rita C.; Oliveira, M.B.P.P.; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.Flowers and vegetative parts of wild Taraxacum identified as belonging to sect. Ruderalia were chemically characterized in nutritional composition, sugars, organic acids, fatty acids and tocopherols. Furthermore, the antioxidant potential and phenolic profiles were evaluated in the methanolic extracts, infusions and decoctions. The flowers gave higher content of sugars, tocopherols and flavonoids (mainly luteol...
Nutritional and antioxidant contributions of Laurus nobilis L. leaves: would b...
Dias, Maria Inês; Barros, Lillian; Dueñas, Montserrat; Alves, Rita C.; Oliveira, M.B.P.P.; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.Medicinal and aromatic plants are used since ancient times in folk medicine and traditional food, but also in novel pharmaceutical preparations. The controversy lies in the use of cultivated and/or wild plants presenting both advantages and disadvantages in biological, ecological but also economic terms. Herein, cultivated and wild samples of Laurus nobilis L. were chemically characterized regarding nutritional...
Two-dimensional PCA highlights the differentiated antitumor and antimicrobial a...
Dias, Maria Inês; Barreira, João C.M.; Calhelha, Ricardo C.; Queiroz, Maria João R.P.; Oliveira, M.B.P.P.; Soković, Marina; Ferreira, Isabel C.F.R.Natural matrices are important sources of new antitumor and antimicrobial compounds. Species such as Laurus nobilis L. (laurel) might be used for this purpose, considering its medicinal properties. Herein, in vitro activity against human tumor cell lines, bacteria, and fungi was evaluated in enriched phenolic extracts. Specifically, methanol and aqueous extracts of wild and cultivated samples of L. nobilis were...
Phenolic profiling of Veronica spp. grown in mountain, urban and sand soil envi...
Barreira, João C.M.; Dias, Maria Inês; Živković, Jelena; Stojković, Dejan; Soković, Marina; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.Veronica (Plantaginaceae) genus is widely distributed in different habitats. Phytochemistry studies are increasing because most metabolites with pharmacological interest are obtained from plants. The phenolic compounds of V. montana, V. polita and V. spuria were tentatively identified by HPLC-DAD-ESI/MS. The phenolic profiles showed that flavones were the major compounds (V. montana: 7 phenolic acids, 5 flavone...
Modelling and analysis of forest fire data in Portugal
Silva, Giovani Loiola; Dias, Maria InesIn the last decade, forest fires have become a natural disaster in Portugal, causing great forest devastation, leading to both economic and environmental losses and putting at risk populations and the livelihoods of the forest itself. In this work, we present Bayesian hierarchical models to analyze spatio-temporal fire data on the proportion of burned area in Portugal, by municipalities and over three decades....

Phenolic profiles of cultivated, in vitro cultured and commercial samples of Me...
Barros, Lillian; Dueñas, Montserrat; Dias, Maria Inês; Sousa, Maria João; Santos-Buelga, Celestino; Ferreira, Isabel C.F.R.Melissa officinalis L. (lemon balm) is normally consumed as infusions and presents therapeutic properties such as sedative, carminative and antispasmodic, being also included in some pharmaceutical preparations. The phenolic profiles of different samples of lemon balm prepared as infusions were evaluated by HPLC-DAD-ESI/MS. The profiles were compared in order to understand the differences between cultivated, in...
