The chemical composition of the brown alga Cystoseira crinita Bory from the Eastern Mediterranean was investigated. Fourteen sterols have been identified, five of them for the first time in algae. The structure of one new sterol was established. The origin of seven sterols with short side chains was discussed. In the volatile fraction 19 compounds and in the polar fraction 15 compounds were ide...
We tested the capacity of Ulva lactuca to mark N sources across large marine areas by measuring variation in its δ(15)N at several sites in the Gulf of Gaeta. Comparisons were made with the macroalga Cystoseira amentacea. Variation of δ(15)N values was assessed also in the coastal waters off the Circeo Natural Park, where U. lactuca and C. amentacea were harvested, as these waters are barely in...
This study set out to examine the cystoseira gibraltarica extract (CG) as an environmentally sustainable corrosion inhibitor for carbon steel in 1.0 M HCl medium. The corrosion inhibiting effect has been studied by conventional methods such as gravimetric (weight loss) and electrochemical (EIS and PDP) methods. All the methods used in this study confirm that cystoseira gibraltarica extract has ...
Due to multiple impacts, Cystoseira forests are experiencing a significant decline, which is affecting the ecosystem services they provide. Despite conservation efforts, there is an urgent need to develop best practices and large-scale restoration strategies. To implement restoration actions, we developed an ex situ protocol for the cultivation of Cystoseira. amentacea var. stricta, aimed at re...
Seaweeds have caused an emerging interest in the biomedical area, mainly due to their contents of bioactive substances which show great potential as anti-inflammatory, anti-microbial, anti-viral and anti-tumoral drugs. Despite the diversity in quality and quantity of the Mediterranean Tunisian coast flora, with its large contains of marine organisms and seaweeds, most of them have not yet been ...

Canopy-forming macroalgae are amongst the main competitors of corals by affecting coral recruitment, growth recruits and adults, fecundity in worst-case scenario causing bleaching necrosis. However, potentially reef-building Cladocora caespitosa (Linnaeus, 1767) canopy-forming order Fucales (Cystoseira sensu lato) known to concur a few places Mediterranean Sea. Here we look at small-scale relat...
Alcoholic extracts of 8 different types of seaweeds from Iran's Persian Gulf were tested for their antimalarial and acetylcholinesterase enzyme (AChE) inhibitory activities for the first time. A modified Ellman and Ingkaninan method was used for measuring AChE inhibitory activity in which galanthamine was used as the reference. The antimalarial assay was performed using microculture radioisotop...
The polysaccharides of Acanthophora spicifera and Cystoseira trinode were isolated and their components identified using different chemical and spectral techniques. Their effects were evaluated for the first time on hyperlipidemic rats. Atorvastatin Ca (Lipitor) was used as a reference drug. Results revealed that the polysaccharides isolated were of sulfate type. Acanthophora spicifera lowered ...
