Subject:
Eisenia arborea; algae; alginates; anticoagulant activity; anticoagulants; antioxidant activity; blades; chemical composition; fucoidan; harvesting; median effective concentration; Mexico
Abstract:
... The aim of this study was to describe the bimonthly variation in the proximate chemical composition, alginate, and fucoidan yield and ethanolic extract content, including the anticoagulant and antioxidant activity of the extracts and quality tests of alginates, from blades and stipes of Eisenia arborea collected in Bahía Magdalena, Baja California Sur, Mexico. Significant differences were found in ...

Leathesia; algae; alginates; antioxidant activity; cytotoxicity; environmental factors; gametogenesis; gametophytes; nutrient content; organic matter; pigments; polyphenols; protein content; seawater; spores; sporophytes; storage time; temperature; zygote
Abstract:
... In recent years, interest in the chemical composition of algae, and the art of farming them, has grown due to their nutritional and health benefits. Species of Leathesia collected from nature have pharmaceutical properties, such as antitumor, antiviral, antioxidant and cytotoxic activity. Accordingly, their culture under controlled conditions is fundamental for the sustainable maintenance of natur ...

Process biochemistry 2019 v.79 pp. 166-173
ISSN:

Subject:
Sargassum muticum; algae; alginates; antioxidant activity; ascorbic acid; cytotoxicity; enzymatic treatment; enzyme activity; enzymes; feedstocks; fibroblasts; humans; melanoma; mice; solubilization; ultrasonics; unsaturated fatty acids
Abstract:
... An ecofriendly process based on an enzyme-assisted extraction coupled with ultrasound extraction was proposed to obtain soluble bioactive fractions from Sargassum muticum. Whole algae (Sm) and residual algae from alginate production (AESm) were employed as feedstock. Aqueous enzyme treatment with commercial complex enzyme formulations or with mixture of enzymes lead to maximum solubilization yield ...

2,2-diphenyl-1-picrylhydrazyl; Sargassum; Staphylococcus aureus; Vibrio parahaemolyticus; algae; alginates; antibacterial properties; antibiotics; anticoagulant activity; anticoagulants; antioxidant activity; crude fiber; energy; free radical scavengers; fucoidan; harvesting; lipids; prothrombin; thromboplastin
Abstract:
... The proximate chemical composition of Sargassum horridum was determined monthly, including extract yields of alginate, crude fucoidan, and ethanolic extract. In addition, the biological activity (antioxidant and antibacterial) of the ethanolic extract and anticoagulant activity of the fucoidan were examined. Significant monthly variation was found in the chemical composition (moisture, protein, as ...
