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...
Citrus Seed Waste and Circular Bioeconomy: Insights on Nutritional Profile, Hea...
Seyyedi-Mansour, Sepidar; Carpena, María; Donn, Pauline; Barciela, Paula; Perez-Vazquez, Ana; Echave Álvarez, Javier; Pereira, Antia GonzalezCitrus fruits are widely grown, processed, and distributed in more than 140 countries, with annual global production exceeding 124.3 million metric tons. This substantial consumption generates significant organic waste, accounting for approximately 50–60% of the total fruit mass, primarily in the form of peel, pulp, and seeds. Often discarded or reused as animal feed, these wastes contribute to significant envi...
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...
Toxicity and safety of nutraceuticals
Barciela, Paula; Perez-Vazquez, Ana; Mansour, Sepidar; Donn, Pauline; Garcia-Perez, P.; Carpena, Maria; Fraga-Corral, Maria; Simal-Gandara, JesusCurrently, consumers are more conscious about the importance of having a good diet and lifestyle; so the demand for products with potential health benefits has increased. Nutraceuticals can be classified according to different criteria. Based on their chemical structure, they can be divided into phenolic compounds, fatty acids and structural lipids, carbohydrates and amino-acids derivatives, minerals, and terpe...
Metabolite Profiling of Macroalgae: Biosynthesis and Beneficial Biological Prop...
Carpena, María; Pereira, Cláudia S.G.P.; Silva, Aurora; Barciela, Paula; Jorge, Ana Olívia Serra; Perez-Vazquez, Ana; Pereira, Antia GonzalezMacroalgae are known as abundant sources of phytochemicals, which offer a plethora of beneficial biological properties. Besides being the most notable classes of compounds found in macroalgae, phlorotannins, bromophenols, and terpenoids comprise some of the most relevant for their biological properties. Phlorotannins, mainly prevalent in brown algae and structurally characterized as complex polyphenolic compoun...
Pressurized liquid extraction for the recovery of bioactive compounds from seaw...
Perez-Vazquez, Ana; Carpena Rodríguez, María; Barciela, Paula; Cassani, Lucia; Simal-Gandara, Jesus; Prieto Lage, Miguel A.Seaweeds are an underutilized food in the Western world, but they are widely consumed in Asia, with China being the world's larger producer. Seaweeds have gained attention in the food industry in recent years because of their composition, which includes polysaccharides, lipids, proteins, dietary fiber, and various bioactive compounds such as vitamins, essential minerals, phenolic compounds, and pigments. Extrac...
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...
