Exploring the potential of invasive species Sargassum muticum: microwave-assist...
Silva, Aurora; Cassani, Lucia; Carpena, Maria; Lourenço-Lopes, Catarina; Grosso, Clara; Chamorro, Franklin; García-Pérez, Pascual; Carvalho, AnaSargassum muticum (SM) poses a serious environmental issue since it is a fast-expanding invasive species occupying key areas of the European shoreline, disrupting the autochthonous algae species, and disturbing the ecosystem. This problem has concerned the general population and the scientific community. Nevertheless, as macroalgae are recognized as a source of bioactive molecules, the abundance of SM presents ...
Nutraceuticals and oxidative stress
Donn, Pauline; Seyyedi-Mansour, Sepidar; Perez-Vazquez, Ana; Barciela, Paula; Fraga-Corral, Maria; Chamorro, Franklin; Cassani, LuciaSeveral studies have found a link between oxidative stress and a variety of noncommunicable diseases including diabetes, obesity, aging, Down syndrome, cancers, cardiovascular, and neurodegenerative diseases. All these pathologies are aided by oxidative stress, which is caused by the excessive production of free radicals or insufficient elimination of free radicals. To avoid, reduce, or eliminate this imbalance...
Natural antioxidants from marine sources and their application in foods
Silva, Aurora; Carpena, Maria; Grosso, Clara; Barciela, Paula; Pereira, Antía González; Cassani, Lucia; Barroso, Maria F.; Simal-Gandara, JesusThis chapter provides an overview of recent studies assessing the antioxidant potential of marine organisms and their bioactive compounds to be incorporated into food products and supplements. Emphasis was given to marine flora, especially micro- and macroalgae and marine invertebrates, namely sponges, seagrasses, sea cucumbers, jellyfishes, crustaceans, and mollusks. The most relevant compounds such as vitamin...
Plant alkaloids: production, extraction, and potential therapeutic properties
Pereira, Antia Gonzalez; Cassani, Lucia; Garcia-Oliveira, Paula; Otero, Paz; Mansoor, Sepidar; Echave Álvarez, Javier; Xiao, JianboAlkaloids are a type of secondary metabolites that can be found in different parts of plants. This group of compounds is diverse and can be divided into nine subgroups: pyridine, tropane, isoquinoline, phenanthrene, phenylethylamine, indole, purine, imidazole, and terpenoids. Most of these compounds are recognized for their anti-inflammatory, antitumor, antibacterial, antifungal, and antiviral activities, among...
Bioactive Compounds of Verbascum sinuatum L.: Health Benefits and Potential as ...
Donn, Pauline; Barciela, Paula; Perez-Vazquez, Ana; Cassani, Lucia; Simal-Gandara, Jesus; Prieto Lage, Miguel A.Verbascum sinuatum (V. sinuatum) is a plant belonging to the Scrophulariaceae family that has been used as an ingredient in traditional medicine infusions for the treatment of many diseases. The aerial part of this plant is a source of bioactive compounds, especially polyphenols and iridoids. Moreover, antioxidant activity studies have shown that V. sinuatum phenolic and flavonoid composition is higher than tho...
Recent progress in understanding the impact of food processing and storage on t...
Gomez-Zavaglia, Andrea; Barros, Lillian; Prieto Lage, Miguel A.; Cassani, LuciaFucoxanthin, a brown algae carotenoid, has attracted great interest because of its numerous biological activities supported by in vitro and in vivo studies. However, its chemical structure is susceptible to alterations when subjected to food processing and storage conditions, such as heat, oxygen, light, and pH changes. Consequently, these conditions lead to the formation of fucoxanthin derivatives, including c...
Application of fermentation for the valorization of residues from Cactaceae family
Carpena Rodríguez, María; Cassani, Lucia; Gomez-Zavaglia, Andrea; Garcia-Perez, Pascual; Seyyedi-Mansour, Sepidar; Cao, Hui; Simal-Gandara, JesusCactaceae family is well-known for their adaptations to drought and arid environments. This family, formed by four subfamilies (Cactoideae, Opuntioideae, Pereskioideae, and Maihuenioideae) are known for being leafless stem succulent plants with numerous spines, and their commercial fruits, distinguished by their bright colors and their skin covered with bracts. Some of these species have been traditionally used...
Algal nutraceuticals: a perspective on metabolic diversity, current food applic...
Garcia-Perez, Pascual; Cassani, Lucia; Garcia-Oliveira, Paula; Xiao, Jianbo; Simal-Gandara, Jesus; Prieto Lage, Miguel A.; Lucini, LuigiThe current consumers’ demand for food naturalness is urging the search for new functional foods of natural origin with enhanced health-promoting properties. In this sense, algae constitute an underexplored biological source of nutraceuticals that can be used to fortify food products. Both marine macroalgae (or seaweeds) and microalgae exhibit a myriad of chemical constituents with associated features as a resu...
Non-alkaloid nitrogen-containing compounds from fungi
Hached, Hanine; Cassani, Lucia; Zbiss, Yosra; Fraga-Corral, Maria; Oliveira, Izamara; Pereira, Antia Gonzalez; Prieto Lage, Miguel A.Fungi represent an ancient ubiquitous and interesting kingdom that can be classified into Phycomycota, Oomycota, Microsporidiomycota, Zygomycota, Ascomycota, Basidiomycota, and Deuteromycota divisions. These microorganisms are considered as a reservoir of bioactive compounds that can be exploited in crucial fields: food, pharmaceutical, and agricultural industries. Non-alkaloid nitrogenated compounds are consid...
Untargeted metabolomics and in vitro functional analysis unravel the intraspeci...
Pereira, Antia Gonzalez; Cassani, Lucia; Oludemi, Taofiq; Chamorro, Franklin; Calhelha, Ricardo C.; Prieto Lage, Miguel A.; Barros, LillianThe Camellia genus comprises a vast array of underexplored medicinal plants that merit a systematic valorization to exploit their potential as natural sources of phytochemicals with associated health-promoting properties. In this work, flower extracts from eight poorly characterized Camellia japonica L. cultivars were subjected to polyphenol profiling through untargeted metabolomics combined with in vitro funct...
