Seaweeds, being prolific sources of bioactive components have garnered unprecedented interest in recent times. The complex polysaccharides from the brown, red and green seaweeds possess broad spectrum therapeutic properties. Especially, the sulfated polysaccharides, viz. fucans, carrageenans and ulvans have exhibited strong antioxidant, antitumor, immunostimulatory, anti-inflammatory, pulmonary...

Seaweeds are becoming a viable source of biologically active composites with hopeful application as nutraceuticals, functional food components, and medicinal agents. In the present study, antioxidant capacity biochemical compositions four seaweeds; Polycladia indica Turbinaria ornata (Phaeophyceae) Laurencia obtusa Sarconema scinaioides (Rhodophyceae), were estimated. The results indicated that...

BACKGROUND The preference for a fairer skin-tone has become a common trend among both men and women around the world. In this study, seaweeds Sargassum polycystum and Padina tenuis were investigated for their in vitro and in vivo potentials in working as skin whitening agents. Seaweed has been used as a revolutionary skin repairing agent in both traditional and modern preparations. The high ant...

The present study investigated the synthesis of silver and gold nanoparticles by two species of brown seaweeds (Padina tetrastromatica and Turbinaria ornata) through analytical techniques and its antimicrobial activity. The brown seaweeds, P. tetrastromatica and T. ornata were collected from Mandabam, The collected freshly seaweeds were thoroughly washed in distilled water. About 20 grams of se...

hepatitis c virus (hcv) has infected 3% of the population worldwide and 20% of the population in egypt. hcv infection can lead to hepatocellular carcinoma and death. the presently available treatment with interferon plus ribavirin, has limited benefits due to adverse side effects. seaweeds have become a major source of new compounds to treat viral diseases. this work aimed to study the effect o...

background: seaweeds contain significant quantities of lipids, protein, vitamins and minerals. aquavac ergosan contains 1% alginic acid extracted from two brown seaweeds, laminaria digitata and ascophyllum nodosum. both in vivo and in-vitro researches have mainly been focused on the effect of ergosan on fish growth, survival rate, reproductive performance and innate immunity in blood and epider...

Seaweeds have been introduced as an important sources of food and pharmaceutical active agents since last century. In this study, the chemical composition and functional characteristics of (common names) Nizamuddinia zanardinii and Iyengaria stellata, were investigated. The total carbohydrate and ash contents were the two most abundant components in these seaweeds but their crude lipid and fibe...

The toxicity of crude extracts of 32 seaweed species from the western Mediterranean was analysed by Microtox® assay in spring and autumn of 1996 and 1997. The species analysed represented more than 76% of seaweed coverage in the 3 algal communities studied: photophilic and sciaphilic communities from the Cabrera Archipelago (Balearic Islands), and a hemisciaphilic community from the Medes Archi...
