Diversity assessment in the Portuguese genebank collection of tomato (Solanum l...
Pinela, José; Montoya, César; Martins, Valter; Nunes, M. Eugénia; Rocha, Filomena; Lopes, Violeta R.; Barata, Ana Maria; Carvalho, Ana MariaTomato germplasm is source of variability used by plant breeders to develop improved cultivars and part of the natural heritage to be preserved. In this study, the diversity among twenty Portuguese tomato accessions was evaluated, considering morphological and agronomic descriptors, molecular data, and compositional aspects. The tomato accessions captured 77.5% of the total 19 alleles detected. Important inform...
Biological and phytochemical evaluation of methanolic extracts from ennyroyal a...
Serrano, Carmo; Barros, Lillian; Soares, Andreia; Pereira, Carla; Dias, Maria Inês; Alves, Maria José; Lopes, Violeta R.; Barata, Ana MariaMedicinal and aromatic plants represent a healthier alternative to synthetic phenolic compounds, with a positive impact on therapeutic, aromatic and dietetic or gastronomic purposes. The in vitro biological activities of the phenolic compounds are an important parameter to select the most promising extracts for use in industrial applications. Thus, this study aimed to evaluate the in vitro antioxidant, antibact...
Phenolic composition and bioactivity of Lavandula pedunculata (Mill.) Cav. samp...
Lopes, Catarina Leonor Afonso do Vale; Pereira, Eliana; Soković, Marina; Carvalho, Ana Maria; Barata, Ana Maria; Lopes, Violeta R.; Rocha, FilomenaThe aim of this study was to characterize the phenolic composition and evaluate the bioactivity of several samples of Lavandula pedunculata (Mill.) Cav, and to compare aqueous and hydroethanolic extracts. Plant materials were obtained by growing some accessions (seed samples) of various wild populations from different regions of Portugal conserved at the Portuguese Genebank in Braga. Phenolic compounds were ana...
Ácidos fenólicos e flavonoides glucosilados em Lavandula pedunculata (Mill.) Cav
Lopes, Catarina Leonor Afonso do Vale; Jiménez López, Cecília; Carvalho, Ana Maria; Rocha, Filomena; Lopes, Violeta R.; Barata, Ana MariaAs plantas contêm na sua composição vários compostos bioativos que exercem efeitos benéficos na saúde humana, nomeadamente na prevenção de doenças associadas com o stresse oxidativo. Os compostos fenólicos são exemplos desses bioativos e, em particular, os ácidos fenólicos e flavonoides que se encontram frequentemente ligados a açúcares, são amplamente reconhecidos por possuírem propriedades antioxidantes [1,2]...

Lopes, Catarina Leonor Afonso do Vale; Pereira, Eliana; Carvalho, Ana Maria; Barata, Ana Maria; Lopes, Violeta R.; Rocha, Filomena; Barros, LillianAo longo da história da humanidade, aproximadamente 7000 espécies de plantas têm sido utilizadas como alimento e também como um recurso essencial para o nosso bem-estar [1]. As espécies do género Lavandula são muito utilizadas, não só na medicina popular, como também na indústria alimentar, no fabrico de bebidas aromatizadas, gelados, doces e pastelaria. São também matéria-prima nas indústrias de perfumaria e f...
Conservation and sustainable uses of medicinal and aromatic plants genetic reso...
Barata, Ana Maria; Rocha, Filomena; Lopes, Violeta R.; Carvalho, Ana MariaPlants have been used since ancient times to heal and cure diseases and to improve the health and the wellbeing of the populations. Medicinal and aromatic plants still form the basis of traditional or indigenous health systems of the populations in most of the developing countries, as reported by the World Health Organization (WHO).As a result of the expanding interest in medicinal and aromatic plants, new inco...
Traditional varieties and associate produces: conserve to valorize.
Barata, Ana Maria; Rocha, Filomena; Lopes, Violeta R.; Gaspar, Carlos; Bettencourt, Eliseu; Carvalho, Ana MariaDiversity is an important approach to plant genetic resources conservation. Landraces and farmer varieties are essential elements of agroecosystems. Several ethnobotanical surveys carried out in different Portuguese regions highlighted the importance of some agroecosystems and enhanced biological, cultural and heritage values of local knowledge, plant-use systems and traditional landscapes.Such importance and r...

The genus Brassica. A shared cultural heritage in the Iberian Peninsula
Silva, Isabel G.; Lopes, Violeta R.; Rocha, Filomena; Barata, Ana Maria; Carvalho, Ana MariaTaxonomic boundaries of the genus Brassica are not clearly defined. Native in the wild in Western Europe, some authors (Gomez-Campo 2003) consider that this genus comprises about 35 species distributed especially in the Mediterranean, with a maximum of diversity in the SW part of this region. Moreover, several of such species are of great economic importance for human uses (vegetables, spices, oils, seeds) and ...
