Pereira, Alexis; Añibarro-Ortega, Mikel; Rocha, Filomena; Lopes, V. Rolim; Carvalho, Ana Maria; Barata, Ana Maria; Barros, Lillian; Pinela, JoséO tomate (Solanum lycopersicum L.) é uma das culturas hortícolas mais importantes em todo o mundo e desempenha um papel fundamental na dieta mediterrânica. Ao longo dos anos, o cultivo de tomate em sistemas agrícolas extensivos, como hortas e quintais, levou ao surgimento de várias variedades tradicionais com características morfológicas e sensoriais distintas. Estas variedades representam um valioso reservatór...
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...

Nutritional and chemical characteristics of Portuguese table tomato genotypes
Pereira, Alexis; Añibarro-Ortega, Mikel; Rocha, Filomena; Lopes, V. Rolim; Carvalho, Ana Maria; Barata, Ana Maria; Barros, Lillian; Pinela, JoséTomato (Solanum lycopersicum L.) is one the most important horticultural crops worldwide and a key component of the Mediterranean diet. Over the years, tomato selection and cultivation in small farming systems, such as homegardens, has resulted in the emergence of several varieties with distinct morphological and sensory characteristics. These varieties represent a valuable genetic diversity reservoir with bree...
Exploiting the nutritional and chemical diversity of Portuguese tomato (Solanum...
Pereira, Alexis; Añibarro-Ortega, Mikel; Rocha, Filomena; Lopes, V. Rolim; Carvalho, Ana Maria; Barata, Ana Maria; Barros, Lillian; Pinela, JoséTomato (Solanum lycopersicum L.) is the second most important vegetable crop worldwide and one of the most preferred garden crops. It is a versatile key component of the Mediterranean diet commonly associated with a reduced risk of chronic degenerative diseases due to its composition in bioactive molecules [1,2]. Throughout its evolutionary and domestication process, this species has undergone diverse genetic a...
Table tomato leaves are a sustainable source of rutin and display antioxidant, ...
Añibarro-Ortega, Mikel; Pinela, José; Ćirić, Ana; Rocha, Filomena; Barata, Ana Maria; Soković, Marina; Carvalho, Ana Maria; Ferreira, Isabel C.F.R.Table tomato (Solanum lycopersicum L.) is highly consumed worldwide and its annual production generates a considerable amount of plant by-products [1]. Although tomatoes are well-known for their composition in nutrients and bioactive compounds [2,3], little information is available in literature regarding tomato leaves, probably because these by-products have no commercial value. Therefore, considering the enor...
Tomato plant biomass: from agricultural by- products to bioactive extracts with...
Pinela, José; Añibarro-Ortega, Mikel; Ćirić, Ana; Rocha, Filomena; Barata, Ana Maria; Soković, Marina; Carvalho, Ana Maria; Ferreira, Isabel C.F.R.Tomatoes are highly consumed worldwide and their annual production generates a significant amount of plant by-products, especially aerial biomass. Although tomatoes are well-known for their nutritional composition and health-promoting effects [1], little information is available in the literature on the plant remains of this crop. Therefore, considering the substantial availability of this natural resource and ...
Valorisation of table tomato crop by-products: Phenolic profiles and in vitro a...
Añibarro Ortega, Mikel; Pinela, José; Ćirić, Ana; Martins, Valter; Rocha, Filomena; Soković, Marina; Barata, Ana Maria; Carvalho, Ana MariaLittle attention has been paid to the phenolic composition and bioactive properties of primary tomato plant by-products (Solanum lycopersicum L.) as compared to fruits. In this study, axillary green shoots resulting from pruning and aerial biomass at the end of the cultivation cycle were characterized for their composition in chlorophylls and phenolic compounds, as well as for antioxidant and antimicrobial acti...
Phenolic composition and antioxidant properties of ex-situ conserved tomato (So...
Pinela, José; Montoya, César; Carvalho, Ana Maria; Martins, Valter; Rocha, Filomena; Barata, Ana Maria; Barros, Lillian; Ferreira, Isabel C.F.R.Tomato (Solanum lycopersicum L.) local varieties represent a reservoir of genetic diversity for desirable quality traits. In this study, a representative collection of table tomato germplasm conserved ex-situ in the Portuguese Gene Bank was characterized for its polyphenols composition and antioxidant capacity. Phenolic acids, such as caffeic and p-coumaric acids bounded to a hexose and 5-O-caffeoylquinic acid,...
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...
