Targeting Skin Aging Hallmarks In Vitro: Antioxidant, Anti-Inflammatory, and An...
Marques, Mário Pedro; Landim, Euclides; Varela, Carla; Costa, Ricardo M. F. da; Marques, Joana; Carvalho, Luís A. E. Batista de; Silva, AnaPlant-based extracts are rich sources of phenolic compounds, which may act as skin antiaging mediators. Herein, Cistus albidus L. (Ca), Cistus ladanifer L. subsp. ladanifer (Cl) and Cistus salviifolius L. (Cs) were selected to test whether their phytochemical profile and bioactive potential align to target human skin aging. Hydroethanolic extracts (HEs) were prepared and characterized using infrared vibrational...
A Spectrochemically Driven Study: Identifying Phenolic-Rich Extracts from Helic...
Marques, Mário Pedro; Landim, Euclides; Varela, Carla; Costa, Ricardo M. F. da; Marques, Joana; Carvalho, Luís A. E. Batista de; Silva, AnaPlants inhabiting mediterranean-influenced climatic zones, like Helichrysum stoechas (L.) Moench subsp. stoechas, Lavandula pedunculata (Mill.) Cav., and Thymus mastichina (L.) L. subsp. mastichina, have been scarcely investigated regarding their richness in phenolic compounds, herein explored as sources of skin anti-aging compounds. In this investigation, Fourier transform infrared spectroscopy (FTIR) in atten...
Exploring the hypocholesterolemic potential of a fucus vesiculosus extract: Omi...
André, Rebeca; Pacheco, Rita; Santos, Hugo M.; Serralheiro, Maria LuísaHigh blood cholesterol levels are a major risk factor for cardiovascular diseases. A purified aqueous extract of Fucus vesiculosus, rich in phlorotannins and peptides, has been described for its potential to inhibit cholesterol biosynthesis and intestinal absorption. In this work, the effect of this extract on intestinal cells' metabolites and proteins was analysed to gain a deeper understanding of its mode of ...
The hypocholesterolemic potential of the edible algae fucus vesiculosus: Proteo...
André, Rebeca; Pacheco, Rita; Alves, Ana Catarina; Santos, Hugo M. M.; Bourbon, Mafalda; Serralheiro, Maria LuisaA brown seaweed consumed worldwide, Fucus vesiculosus, has been used to prevent atherosclerosis and hypercholesterolemia, among other uses. However, the mechanisms of action that lead to these effects are not yet fully understood. This work aims to study the in vitro effect of an aqueous extract of F. vesiculosus, previously characterized as rich in phlorotannins and peptides, on the expression of different pro...
Molecules for health : cholesterol absorption and transporter proteins expressi...
André, RebecaHigh levels of cholesterol blood and accumulation of cholesterol in tissues are one of the major risk factors to cardiovascular disease. One of the main ways to reduce cholesterol levels is by adopting a healthy diet. The search for healthy and sustainable food has resulted in an increase in the consumption of algae. Fucus vesiculosus is a brown seaweed used in food all over the world. The objective of this wor...
Brown algae potential as a functional food against hypercholesterolemia: review
André, Rebeca; Pacheco, Rita; Bourbon, Mafalda; Serralheiro, Maria LuisaBrown algae have been part of the human diet for hundreds of years, however, in recent years, commercial and scientific interest in brown algae has increased due to the growing demand for healthier diet by the world population. Brown algae and its metabolites, such as carotenoids, polysaccharides, phlorotannins, and proteins, have been associated with multiple beneficial health effects for different diseases, s...

Undaria pinnatifida (U. pinnatifida) bioactivity: Antioxidant, gastro-intestina...
Pedro, Bernardo; Guedes, Laura; André, Rebeca; Gaspar, Helena; Vaz, Pedro; Ascensão, Lia; Melo, Ricardo; Serralheiro, Maria LuisaUndaria pinnatifida is a brown alga, largely used as food in oriental countries. The purpose of this work was to analyze several bioactivities that might be present in different food preparations, relating them with the compounds present in the extracts. Aqueous extracts cooked, like a soup, as well as used in a salad, by simulating U. pinnatifida digestion with pancreatin were prepared. The soup preparation ha...
Effect of food preparations on in vitro bioactivities and chemical components o...
André, Rebeca; Guedes, Laura; Melo, Ricardo; Ascensão, Lia; Pacheco, Rita; Vaz, Pedro D.; Serralheiro, Maria LuisaFucus vesiculosus is a brown macroalgae used in food and generally considered safe to be consumed, according to EU Directive (EC 258/97). The aim of this study is to analyze the e_ect of food preparation on F.vesiculosus of di_erent origins on what concerns its chemical constituents and final bioactivities. The aqueous extract of the seaweeds were obtained at di_erent temperatures, similar to food preparation a...
