Laurus Azorica Leaves : Sesquiterpene Lactones and Antiaging Activity
Viveiros, Mariana Moniz; Barreto, Maria do Carmo; Seca, Ana M. L.Plants are a relevant source of biologically active compounds for skin protection. Laurus azorica (Seub.) Franco, an endemic species from Azores, was traditionally used as a disinfectant, and the oil from its berries was used to treat wounds. This species is barely studied concerning its chemical constituents and biological activities. In this study, three sesquiterpene lactones, costunolide, 11,13-dehydrosanto...

Seca, Ana M. L.; Faustino, Luís M. M.; Viveiros, Mariana Moniz; Rosa, Gonçalo P.; Barreto, Maria do CarmoBeach-cast seaweeds are a seasonal phenomenon consisting of the accumulation of large tons of algae on beaches, which is unpleasant for beach users and affects the tourism industry, mainly because tourists often interpret stranded natural litter as lowering beach quality, especially if the material starts to decompose. These beach casts are always variable mixtures of different species of seagrass and seaweeds....
Laurus azorica : Valorization through Its Phytochemical Study and Biological Ac...
Viveiros, Mariana Moniz; Barreto, Maria do Carmo; Seca, Ana M. L.Laurus azorica (Seub.) Franco is an endemic species from the Azores, traditionally used in all the islands as a seasoning in cooking. The studies carried out with this species refer mainly to its essential oils. The study that was developed here allowed, for the first time, to determine the chemical composition and biological activities of the ethanol extract, fractions, and pure compounds from L. azorica.

Potencial antienvelhecimento do extrato etanólico de Laurus azorica e seus cons...
Viveiros, Mariana MonizO envelhecimento da pele é essencialmente causado pela formação contínua de espécies reativas de oxigénio e por uma exposição excessiva à radiação ultravioleta, provocando alterações na matriz extracelular (ECM) devido ao aumento de atividade das enzimas colagenase, elastase, hialuronidase e tirosinase. A pesquisa de produtos naturais com potencial antienvelhecimento tem sido, nos últimos anos, foco de investig...
