The edible Fucus spiralis life-cycle : GC-MS profile analysis
Seca, Ana M. L.; Aguiar, Nuno F. B.; Gouveia, Vera L. M.; Silva, Artur M. S.; Pinto, Diana C. G. A.Fucus spiralis Linnaeus, known in Azores as "Fava-do-mar'' is an edible brown macroalga (Ochrophyta (Phaeophyceae)) which can be found on rocks at upper intertidal leveis, where it forms a patchy zone. It is the only member of the genus Fucus that can be found in Azores and its receptacles are eaten as a local delicacy. Nutritionally, it is very rich in fiber (crude content 63.9% dw) contains important minerais...
Cystoseira abies-marina life cycle : comparative study of its polar profile by ...
Seca, Ana M. L.; Lopes, Diana; Gouveia, Vera L. M.; Silva, Artur M. S.; Pinto, Diana C. G. A.Macroalgae, are largely used in food, pharmaceutical and cosmetics industries. Cystoseira abies-marina (S.G. Gmelin) C. Agardh is a brown macroalgae (Phaeophyta) which belongs to Cystoseira genus and is distributed in the Mediterranean, Macaronesian Region and the coast of Africa. In the Azores lslands, it grows abundantly in the intertidal zone where it is pioneer and attains large size. Since intertidal seawe...
Cytotoxic meroterpenoids from the macroalga Cystoseira abies-marina
Gouveia, Vera L. M.; Seca, Ana M. L.; Barreto, Maria do Carmo; Neto, Ana I.; Kijjoa, Anake; Silva, Artur M. S.Two new meronorsesquiterpenes (cystoazorones A and B) and two new meroditerpenes (cystoazorols A and B), along with benzoic acid were isolated from the brown macroalga Cystoseira abies-marina. The structures of the new compounds were established by 1D and 2D NMR as well as HRMS spectral analysis. The in vitro cytotoxicity and antioxidant activity of the isolated compounds were also evaluated. Cystoazorones A an...
Di- and Sesquiterpenoids from Cystoseira Genus: structure, intra-molecular tran...
Gouveia, Vera L. M.; Seca, Ana M. L.; Barreto, Maria do Carmo; Pinto, Diana C. G. A.Natural products have been the single most productive source of leads for the development of drugs, because of the great variety of their chemical structures. Previous chemical investigation of members of the genus Cystoseira resulted in the discovery of various bioactive secondary metabolites. The secondary metabolites isolated and characterized are very interesting, both from the biological activity and struc...
Avaliação do potencial farmacológico de metabolitos secundários de Cystoseira a...
Gouveia, Vera L. M.A pesquisa de Produtos Naturais com propriedades farmacológicas tem vindo a crescer, destacando-se a descoberta de moléculas vindas de organismos marinhos, que devido à sua considerável biodiversidade se reflecte em metabolitos secundários com estruturas únicas e com várias funcionalidades. Este trabalho surge no seguimento de uma investigação feita com algas do mar dos Açores, cujas actividades biológicas se m...
Bioactive meroditerpenes from Cystoseira abies-marina, collected from the coast...
Gouveia, Vera L. M.; Seca, Ana M. L.; Barreto, Maria do Carmo; Silva, Artur M. S.; Kijjoa, AnakeMany substances isolated from marine organisms have demonstrated to possess interesting biological and pharmacological activities and have been used as leads in the development of new pharmaceutical agents. Marine macroalgae are abundant and structuring organisms of the coastal area of all the islands in the Azores Archipelago; some have a markedly seasonal pattern and others are perennial and present during th...
Purification and structural characterization of compounds isolated from Cystose...
Gouveia, Vera L. M.; Seca, Ana M. L.; Barreto, Maria do Carmo; Silva, Artur M. S.; Kijjoa, AnakeAlthough the Azores archipelago is rich in algal communities, only two papers have been published concerning the nutritional and pharmacological potential of this resource in the Azorean sea.[4,5,6] As a brown alga Cystoseira abies-marina grows abundantly in the coast of these islands and has a great resistance to predation, which indicates the presence of potential active compounds[7], we have investigated its...
