Bioactivity of Matricaria chamomilla, Echinacea purpurea, Thymbra capitata and ...
Valente, João Vasco; Gomes, Carolina Proença; Oliveira, Ana Sofia; Rolo, Joana; Gaspar, Carlos; Caramelo, Débora; Gonçalves, José CarlosThe numerous health benefits associated with the use of plants in traditional medicine can be linked to secondary metabolites in the products obtained through the hydrodistillation process, such as hydrolates and essential oils (EOs). This study aimed to assess the chemical profile and the antioxidant, antimicrobial, cytotoxic, and anti-inflammatory activities of two hydrodistillation products obtained from fou...
Reproductive toxicity assessment of four portuguese plant hydrolates: Effects o...
Dias, Sandra D.F.; Andrade, L.P.; Rolo, Joana; Gaspar, Carlos; Ruivo, Patrícia Gomes; Oliveira, Ana Sofia; Ferreira, Sandra SaraivaExtracts of aromatic medicinal plants have been extensively studied regarding their numerous bioactivities. However, despite being highly used by humans, studies on the safety of these extracts for animal use are scarce. In this study, we aim to contribute to the determination of the safety profile of plant extracts by focusing on the reproductive toxicity of hydrolates (a by-product of essential oils productio...
Culturas de cobertura do solo em pomares
Veloso, Abel; Monteiro, M.C.H.; Delgado, F.M.G.; Gonçalves, José Carlos; Simões, M.P.O glifosato e o seu principal produto de degradação (o AMPA) têm um elevado potencial de persistência nos solos de pomares de pessegueiro da Beira Interior. As culturas de cobertura podem influenciar a disponibilidade de nutrientes e de água do solo. A presença de culturas de cobertura está normalmente associada a um aumento da biodiversidade e da atividade de microrganismos benéficos do solo. As culturas de co...
In vitro propagation and conservation of Lavandula stoechas subsp. luisieri and...
Domingues, Joana Lopes; Eira, Anabela; Ramalho, Isa; Barrocas, Inês; Gonçalves, José CarlosLavandula stoechas subsp. luisieri and Pterospartum tridentatum are two valuable aromatic and medicinal plants. Their biometric and morphological parameters, such as the number of new shoots, length of the longest shoot, multiplication rate, and fresh weight, were evaluated using the multiplication MS medium protocol. The rooting protocols involved immersing the explants in IBA (1 g L−1) and a commercial IBA (3...
Humulus lupulus aqueous extract and hydrolate as a potential ingredient for cos...
Valente, João Vasco; Oliveira, Rita Palmeira de; Guiomar, Liliana; Vaz, Cátia; Rolo, Joana; Gaspar, Carlos; Oliveira, Ana Sofia; Caramelo, DéboraHumulus lupulus extracts have in their composition different molecules, such aspolyphenols, α-acids, β -acids, and hydrocarbons, which contribute to the plant’s medicinal properties. These molecules are associated with antimicrobial, antioxidant, and anti - inflammatory activities. OBJECTIVE This work focuses on the evaluation of H. lupulus biological activities, with the aim of evaluating its potential for inc...
Labdanum resin from Cistus ladanifer L. as a source of compounds with anti-diab...
Frazão, David F.; Delgado, F.M.G.; Gonçalves, José Carlos; Gomes, Carlos Martins; Sosa Diaz, Teresa; Silva, Amélia M.Labdanum resin or “gum” can be obtained from Cistus ladanifer L. by two different extraction methods: the Zamorean and the Andalusian processes. Although its main use is in the fragrance and perfumery sectors, ethnobotanical reports describe its use for medicinal purposes in managing hyperglycemia and mental illnesses. However, data concerning the bioactivities and pharmacological applications are scarce. In th...
A systematic analysis of nutritional and mineral composition and toxicity in Ac...
Pedro, Soraia; Gonçalves, Joana; Monteiro, M.C.H.; Gonçalves, José Carlos; Gominho, Jorge; Gallardo, Eugenia; Anjos, OféliaIn the present study, the nutritive composition and mineral content of the leaves of eight species of Acacia trees were evaluated to assess their potential for different purposes, such as food resources for ruminants and mineral sources in soils. Caco-2 cells were employed to assess cytotoxicity, revealing that the extracts exhibited no cytotoxic effects after cellular incubation, suggesting their suitability a...
Mediterranean Lavenders from Section Stoechas: An Undervalued Source of Seconda...
Domingues, Joana Cristina; Delgado, Fernanda; Gonçalves, José Carlos; Zuzarte, Mónica; Duarte, Ana PaulaGlobally, climate change and wildfires are disrupting natural ecosystems, thus setting several endemic species at risk. The genus Lavandula is widely present in the Mediterranean region and its species, namely, those included in the section Stoechas, are valuable resources of active compounds with several biological assets. Since ancient times lavenders have been used in traditional medicine and for domestic pu...
First chemical profile analysis of acacia pods
Pedro, Soraia; Fernandes, Tiago A.; Luís, Ângelo; Antunes, Alexandra M.M.; Gonçalves, José Carlos; Gominho, Jorge; Gallardo, Eugenia; Anjos, O.This study intended to evaluate the potential industrial applications of various Acacia species (Acacia melanoxylon, Acacia longifolia, Acacia cyclops, Acacia retinodes, Acacia pycnantha, Acacia mearnsii, and Acacia dealbata) by examining their chemical composition, antioxidant, and antimicrobial properties. Using high-resolution mass spectrometry, a comprehensive analysis successfully identified targeted compo...
