During our on-going screening program designed to isolate natural compounds from marine environments, we isolated isoketochabrolic acid (IKCA) from Sargassum micracanthum, an important brown algae distributed in Jeju Island, Korea. Furthermore, we evaluated the inhibitory effects of IKCA on nitric oxide (NO) production in lipopolysaccharide (LPS)-triggered macrophages. IKCA strongly inhibited N...

More than 3000 MT of Sargassum illicifolium ,annually washed-up from the Oman Sea (Sistan and Baluchestan province). , According to the estimates of the Iranian Fisheries Sciences Researchinstitiute.The brown seaweed biomass has been considered as one of the best free sources for production of sodium alginate. A key objective of this study was to determine the biochemical composition of Sargass...

Massive quantities of the pelagic brown macroalgae Sargassum spp. (sargassum) have been invading Caribbean and West African shores since 2011, causing devastating effects on coastal ecosystem local economy. Little is known about sargassum beaching dynamics capacity system to naturally remove beached sargassum. Here, we characterize temporal variation in arriving a reef lagoon using 5.2-year dat...

The amount of sargassum seaweed washed ashore on the beaches Africa, Brazil, Central America and Caribbean has increased to point where it become a social, environmental financial issue. This research evaluates potential for Sargassum spp. Mexican coast be used in production biomethane by estimating: a) stoichiometric methane (SMP), b) biochemical (BMP) c) biodegradability index (BI). use sigmo...

Rumput laut merupakan sumber daya hayati yang melimpah di perairan Indonesia tumbuh pada substrat bebatuan. memiliki potensi sebagai bahan pangan alternatif dengan nilai kandungan nutrisi besar. Sargassum rumput dalam kelas Phaeophyta atau coklat. coklat diketahui mempunyai (kadar karbohidrat, protein, lemak), mineral esensial dan juga mengandung senyawa bioaktif, berdasarkan hasil dari metabol...

BACKGROUND AND OBJECTIVES Antitumor drug resistance and side effects of antitumor compounds are the most common problems in medicine. Therefore, finding new antitumor agents with low side effects could be interesting. This study was designed to assay antitumor activity of the extract from brown alga Sargassum oligocystum, gathered from Persian Gulf seashore, against K562 and Daudi human cancer ...

A detailed, methodical approach was used to synthesise silver and gold nanoparticles using two differently prepared aqueous extracts of the brown algae Sargassum incisifolium. The efficiency of the extracts in producing nanoparticles were compared to commercially available brown algal fucoidans, a major constituent of brown algal aqueous extracts. The nanoparticles were characterised using TEM,...

cales) are known to contain structurally unique secondary metabolites, such as plastoquinones, chromanols, a cyclopentenone, and polysaccharides. These compounds show various biological activities due to their unique structure. We previously reported that the methanolic extract of the brown alga, Sargassum micracanthum (KUETZING) ENDLICHER, “Togemoku” in Japanese, showed strong antioxidant acti...
