Abstract The phenolic compounds contain antioxidant properties that can be effective in the treatment of some chronic and malignant diseases. The aim of this study was to determine optimal conditions for extraction of total phenolic compounds from Sargassum sp. and Sea lettuce (Ulva sp.) in Chabahar coastal waters. The extracts of these two algae were extracted by ultrasonic method and then th...

Low molecular weight polysaccharides can be isolated from Sargassum thunbergii (LMPST) and in vitro experiments were conducted to evaluate the inhibitory effects on lipids. Two natures of LMPST attained from Sargassum appraised their palmitic acid induced lipid accretion HepG2, 3T3-L1 cells. treatment lessened deposition intracellular free fatty triglyceride intensities PA-treated ...

Marine algae and bacteria are an inexhaustible source of chemical compounds that produce a wide variety of biologically active secondary metabolites. Marine bacteria have become an important target for the biotechnology industry because of the large number of bioactive compounds recently discovered from them. The aim of this study was to evaluate the antibacterial and anticancer activities of e...

The immune system plays an important role in maintaining and protecting human health. In the present study, comparison of immuno-modulatory activities between polysaccharides (SFP) and ethanol (SFE) extracts separated from Sargassum fulvellum in macrophages and murine splenocytes were investigated. Immuno-modulatory activities of macrophages were estimated based on cell proliferation, nitric ox...

The mobile epifauna colonizing the invasive brown alga Sargassum muticum (Yendo) Fensholt was compared with assemblages inhabiting two locally established seaweeds (Fucus vesiculosus L. and Cystoseira nodicaulis (Whit.) Roberts) in a sheltered locality of northern Spain. The epifauna colonizing S. muticum was studied in both the shallow subtidal and intertidal pools at mid shore. The main aims ...

Sargassum horneri is an edible marine brown alga distributed along the seacoast of Japan. Here we examined effects on the water-soluble (ethanol-insoluble) extracts (EIS) from Sargassum horneri on ion transports across the isolated rat colonic mucosa set in Ussing chambers. The nonpolysaccharide fraction of EIS (EIS-2) significantly decreased short-circuit current (Isc) across the mucosa, and i...

In the present study, we evaluated the effect of brown seaweeds Sargassum muticum methanolic extract (SMME), against MCF-7 and MDA-MB-231 breast cancer cell lines proliferation. This algae extract was also evaluated for reducing activity and total polyphenol content. The MTT assay results indicated that the extracts were cytotoxic against breast cancer cell lines in a dose-dependent manner, wit...

Five glycerol derivatives (1-5) and three sterols (6-8) were isolated from the EtOH extraction of the brown alga of Sargassum parvivesiculosum. On the basis of spectroscopic methods, their structures were elucidated as 1,3-di-O-[2',2'-di-(p-phenylene) isopropylidene] glycerol (1), (2S)-1-O-heptatriacontanoyl glycerol (2), (2S)-1,2-di-O-palmitoyl-3-O-(6-sulpho-alpha-D-quinovopyranosyl) glycerol ...
