“…Moreover, the types of binding and branching and their monomeric composition may also exert moderate modulation on the biological properties of these sulfated polysaccharides [157,163,164]. In this context, it is possible that the anticoagulant/antithrombin activities exhibited by larger fucoidans are due to the higher content of the fucose and sulfate groups [78,156,161,163,164], although this is still under discussion [160,165,166].…”

Riverine, estuarine, and coastal populations have always used algae in the development of home remedies that were then used to treat diverse health problems. The empirical knowledge of various generations originated these applications, and their mechanism of action is, in most cases, unknown, that is, few more scientific studies would have been described beyond simple collection and ethnographic recording. Nevertheless, recent investigations, carried out with the purpose of analyzing the components and causes that alter the functioning and the balance of our organism, are already giving their first results. Water, and especially sea water is considered as essential to life on our planet. It sings all the substances necessary and conducive to the development of the living being (minerals, catalysts, vitamins, amino acids, etc.). Oceans cover over 70% of Earth, being home to up to 90% of the organisms in the planet. Many rich resources and unique environments are provided by the ocean. Additionally, bioactive compounds that multiple marine organisms have a great potential to produce can be used as nutraceuticals, pharmaceuticals, and cosmeceuticals. Both primary and secondary metabolites are produced by algae. The first ones are directly implicated in development, normal growth, or reproduction conditions to perform physiological functions. Stress conditions, like temperature changes, salinity, environmental pollutants, or UV radiation exposure cause the performance of secondary metabolites. In algae, proteins, polysaccharides, fatty acids, and amino acids are primary metabolites and phenolic compounds, pigments, vitamins, sterols, and other bioactive agents, all produced in algae tissues, are secondary metabolites. These algal active constituents have direct relevance in cosmetics.

“…Nevertheless, this panorama is currently shifting as macroalgae are becoming more and more popular since, in addition to not competing with food crops for the use of arable land and fresh water resources, they are claimed to be a good supply of key nutrients including carbohydrates, protein and minerals [2], as well as a rich source of health-promoting compounds capable of acting on a wide spectrum of disorders and/or diseases [3]. Note also that the Japanese have the world’s longest life expectancy, which has been partly associated with their different dietary patterns, and of course, the regular consumption of macroalgae [4].…”

Seaweeds are known to be a good supply of key nutrients including carbohydrates, protein, minerals, polyunsaturated lipids, as well as several other health-promoting compounds capable of acting on a wide spectrum of disorders and/or diseases. While these marine macroalgae are deeply rooted in the East Asian culture and dietary habits, their major application in Western countries has been in the phycocolloid industry. This scenario has however been gradually changing, since seaweed consumption is becoming more common worldwide. Among the numerous edible seaweeds, members of the genus Fucus have a high nutritional value and are considered good sources of dietary fibers and minerals, especially iodine. Additionally, their wealth of bioactive compounds such as fucoidan, phlorotannins, fucoxanthin and others make them strong candidates for multiple therapeutic applications (e.g., antioxidant, anti-inflammatory, anti-tumor, anti-obesity, anti-coagulant, anti-diabetes and others). This review presents an overview of the nutritional and phytochemical composition of Fucus spp., and their claimed biological activities, as well as the beneficial effects associated to their consumption. Furthermore, the use of Fucus seaweeds and/or their components as functional ingredients for formulation of novel and enhanced foods is also discussed.

“…Seaweeds contain numerous substances such as carrageenan, alginate, and agar as phycocolliods which have bacteriostatic and bactericidal properties (GORBAN & al [5]; EL-SHEEKH & al [6]). The marine algal extracts have many phytochemicals, such as alkaloids, flavonoids steroids, terpenes, glycosides, tannins and phenolic compounds (CARDOSO & al [7]; SUMAYYA & MURUGAN [8]). Furthermore, halogenated ketone, fatty acids, alkalines, and cyclic polysulphides were recorded (CHEUNG & al [9]; KHELIL-RADJI & al [10]).…”

This study was carried out to evaluate the antibacterial activity of ethanol, methanol, acetone, and ethyl acetate extracts of the brown seaweeds, Cystoseira myrica, Padina boergesenii and Sargassum cinereum (Phaeophyta), as well as to identify the phytochemical constituents of the most effective algal extracts. Antibacterial activities were expressed as inhibition zones and minimum inhibitory concentrations (MICs) of the algal extracts. All seaweed extracts tested exhibited a broad spectrum of antibacterial activity. The maximum inhibition activities were recorded for methanolic extracts of P. boergesenii and ethyl acetate extracts of C. myrica and S. cinereum against Shigella flexneri, Staphylococcus aureus (MRSA) and Staphylococcus aureus, respectively. The MIC values of the marine algal extracts tested for inhibiting pathogenic bacteria ranged from 3.13 to 300 mg/ml. GC-MS and FTIR analyses of algal extracts revealed the chemical components and their functional constituents in the brown seaweeds that might have potent antimicrobial activities. These components include fatty acids esters, alcohols, phenols, amines-containing compounds and others. The results indicated that brown seaweeds may be main sources of phytoconstituents which exhibited antibacterial properties and will be helpful in diminishing the adverse effects of synthetic drugs.
