Pharmacological effects of Fucus spiralis extracts and phycochemicals: a comprehensive review

Botanica Marina, 2019
Abstract The value of macroalgae to the pharmaceutical and food industries has increased, due to their richness in compounds with relevant biological activities and health effects. However, there are still many species that are worth exploring, like the edible Fucus spiralis L., widespread throughout the European and African Atlantic ...

Drought stress, rain and recovery of the intertidal seaweed Fucus spiralis

Marine Biology, 2011
Non-motile organisms of intertidal shores such as seaweeds have to cope with a great variability of environmental factors. In this survey, we studied whether different morphotypes of the intertidal seaweed Fucus spiralis L. are also reflected in a characteristic performance.

Dermocosmetic potential of the macroalgae Fucus spiralis

2021
A pele é o maior órgão do corpo humano estando sujeita a fatores intrínsecos e extrínsecos que influenciam negativamente a sua homeostasia, particularmente a exposição à radiação ultravioleta. A contínua exposição da pele a agentes nocivos pode despoletar o stress oxidativo que está associado não só ao envelhecimento cutâneo, mas também ao ...

Competitive interactions between Fucus spiralis L. and F. vesiculosus L. (Fucales, Phaeophyta)

Hydrobiologia, 1990
Fucus spiralis forms a conspicuous belt in the upper intertidal on rocky shores of the NW Atlantic. The objective of this study was to determine whether competition among congeners plays a role in restricting the distribution of F. spiralis to the upper shore. A replacement series design was used to test the growth performance of F.

Induction of plantlets in axenically cultivated rhizoids of Fucus spiralis

Canadian Journal of Botany, 1984
Rhizoids of Fucus spiralis were cultivated axenically in the artificial seawater ASP6 F2. Experiments were made to increase the filamental growth as well as to induce adventive primordia (plantlets). Additions of such carbon compounds as glucose, acetate, and formate had no favourable effects even in concentrations as low as 1∙10−4 M.

Characteristics of arsenic accumulation by the seaweeds Fucus spiralis and Ascophyllum nodosum

Marine Biology, 1980
This study examines the accumulation of 74As-arsenic in the seaweeds Fucus spiralis (L.) and Ascophyllum nodosum (L.) collected from Restronguet Creek in southwest England during 1978. Also, the influence of environmental factors (valence state of arsenic, pH, salinity, temperature, phosphate concentration) and metabolic inhibitors on the uptake of ...

NITROGEN UPTAKE BY FUCUS SPIRALIS (PHAEOPHYCEAE)^1,2

Journal of Phycology, 1978
ABSTRACTAmmoniun, nitrate and nitrite update by Fucus spiralis L. from the Massachusetts coast was examined. Uptake of all appeared to follow saturation type nutrient uptake kinetics, with uptake often restricted at ambient nutrient concentrations. Although only relatively large difference in K8 values could be easily distinguished, K8 values for NO3 ...

Extraction, characterization and application of phlorotannin enriched extracts from macroalgae Fucus spiralis

2021
Fucus spiralis (F. spiralis) é uma alga castanha, abundante em águas frias a temperadas ao longo do hemisfério norte. Estas algas são ricas em compostos bioativos, de entre os quais se destacam os florotaninos que são polifenóis derivados do floroglucinol com importantes propriedades antioxidantes.
