Green and Innovative Extraction: Phenolic Profiles and Biological Activities of...
Pallarés, Noelia; Berrada, Houda; Ferrer, Emilia; Rached, Wahiba; Pinela, José; Mandim, Filipa; Pires, Tânia C.S.P.; Finimundy, Tiane C.Underutilized plant species such as Asteriscus graveolens (Forssk.) Less., Haloxylon scoparium Pomel, and Ruta chalepensis L. have been historically valued in traditional medicine for their potential health benefits. These species present an untapped source of bioactive compounds with significant applications in the food and pharmaceutical industries, including the development of functional foods and additives....
Nutrients, Phytochemicals, and In Vitro Biological Activities of Goldenberry (P...
Añibarro-Ortega, Mikel; Dias, Maria Inês; Petrović, Jovana; Mandim, Filipa; Núñez, Sonia; Soković, Marina; López, Víctor; Barros, Lillian; Pinela, JoséThis study provides a comprehensive characterization of Physalis peruviana L., covering the nutritional composition of the fruit and the phytochemical profiles and in vitro bioactive properties of berry and calyx extracts. The fresh fruit stood out as a source of dietary fiber (5.16 g/100 g) and is low in fat (0.49 g/100 g). A 100-g serving also contained notable amounts of ascorbic acid (32.0 mg), tocopherols ...
Green extraction of anthocyanin from red cabbage waste using acid whey as a pro...
Oliveira, Jaine; Benvenutti, Laís; Albuquerque, Bianca R.; Finimundy, Tiane C.; Mandim, Filipa; Pires, Tânia C.S.P.; Pereira, Carla; Corrêa, Rúbia C.G.The use of acid whey as a biological-based solvent may be an innovative and sustainable strategy to add value to agro-industrial by-products. This study assessed acid whey as a solvent for extracting anthocyanins from discarded red cabbage leaves. Methods such as Heating and Stirring Extraction (HSE), Ultrasound-Assisted Extraction (UAE), and Pressurized Liquid Extraction (PLE) were compared using acid whey or ...
Phytochemical diversity and biological activities of Hypericum japonicum and Hy...
Barciela, Paula; Rodrigues, Daniele B.; Perez-Vazquez, Ana; Silveira, Tayse F.F. da; Pires, Tânia C.S.P.; Mandim, Filipa; Carpena, Maria; Pereira, CarlaThis study characterizes two species of the genus Hypericum to envisage their applicability as effective and versatile functional foods, dietary supplements, and food preservatives. A wide phenolic composition was found in both extracts, highlighting flanovoids for H. japonicum and xanthones for H. sampsonii. Moreover, anthocya- nins were analyzed for the first time in the latter plant. Antioxidant capacity was...
Exploring acorn shells: Phenolic composition and bioactive potential for sustai...
Mateus, Cristiano; Alonso-Esteban, José Ignacio; Finimundy, Tiane C.; Mandim, Filipa; Oliveira, Izamara; Babo, Pedro; Ferreira, Isabel C.F.R.Pedunculate (Quercus robur L.), holm (Quercus rotundifolia Lam.), and cork (Quercus suber L.) oaks are abundant across the Portuguese landscape. This study aims to evaluate the phenolic composition and bioactivities of acorn shell samples and determine their potential as a functional compound source. In total, five acorn shell samples collected in different locations and from different species were analyzed: Q....
Nutritional profile, phytonutrient composition and biocidal properties of Portu...
Paschoalinotto, Beatriz H.; Chrysargyris, Antonios; Añibarro-Ortega, Mikel; Pires, Tânia C.S.P.; Mandim, Filipa; Dias, Maria Inês; Tzortzakis, NikolaosThe contribution of the ammonium: total nitrogen ratio (Nr0.01-0.15) in the nutrient solution on chemical profile and bioactive characteristics of Portulaca oleracea, investigated. Increased Nr levels resulted in increased proteins, total fats, carbohydrates and oxalic acid in leaves and stems, but decreased yield. The only detected tocopherol isoforms were alpha- and beta-tocopherol, with the former to reveal ...
Antioxidant Activity, Antiproliferative Activity, Antiviral Activity, NO Produc...
Sena, Jéssica da Silva; Rodrigues, Selma Alves; Sakumoto, Karina; Inumaro, Rodrigo Sadao; González-Maldonado, Pamela; Mendez-Scolari, EmilioThe chemical composition of extracts (CEs) and essential oils (EOs) from Tetradenia riparia leaves, flower buds, and stems was analyzed. Antiproliferative activity against tumor cell lines, NO production inhibition, and antioxidant and antiviral activities were assessed. The CEs contained flavonoids, phenolic acids, coumarins, and saturated fatty acids. The EOs included monoterpenes, oxygenated sesquiterpenes, ...
Recovery of anthocyanins from Eugenia spp. fruit peels: a comparison between he...
Albuquerque, Bianca R.; Pinela, José; Pereira, Carla; Mandim, Filipa; Heleno, Sandrina A.; Oliveira, Beatriz; Barros, LillianNatural colorants have gained increased popularity among consumers and food producers due to their reputation as safer and healthier alternatives to commonly used artificial analogues. These natural pigments can be obtained from by-products resulting from food processing, such as the fruit peels of the Brazilian species Eugenia brasiliensis and Eugenia involucrata, thus contributing to the valorisation and circ...
Effect of Different Seasons and Development Stages on the Chemical Composition ...
Mandim, Filipa; Carocho, Márcio; Petropoulos, Spyridon Α.; Santos-Buelga, Celestino; Barros, LillianCynara cardunculus L. (cardoon) is a wild species of the Mediterranean basin and is highly appreciated due to its rich nutritional value and versatile industrial applications. It is widely known that environmental conditions, such as air temperature, humidity, and solar radiation, among others, play a crucial role in plant phenological variations and the chemical composition and bioactive properties of differen...
Gastrointestinal digestion of yerba mate, rosemary and green tea extracts and t...
Correa, Vanesa G.; Garcia-Manieri, Jessica Amanda Andrade; Dias, Maria Inês; Pereira, Carla; Mandim, Filipa; Barros, Lillian; Ferreira, Isabel C.F.R.Polyphenolic compounds are common constituents of human and animal diets and undergo extensive metabolism by the gut microbiota before entering circulation. In order to compare the transformations of polyphenols from yerba mate, rosemary, and green tea extracts in the gastrointestinal tract, simulated gastrointestinal digestion coupled with colonic fermentation were used. For enhancing the comparative character...
