Partial characterization and anticoagulant activity of a heterofucan from the brown seaweed Padina gymnospora.
The brown algae Padina gymnospora contain different fucans. Powdered algae were submitted to proteolysis with the proteolytic enzyme maxataze. The first extract of the algae was constituted of polysaccharides contaminated with lipids, phenols, etc. Fractionation of the fucans with increasing concentrations of acetone produced fractions with different proportions of fucose, xylose, uronic acid, ...
متن کاملUse of Fourier Transform Infrared (FTIR) Spectroscopy to Study Cadmium-Induced Changes in Padina Tetrastromatica (Hauck)
The aim of this study is to adopt the approach of metabolic fingerprinting through the use of Fourier Transform Infrared (FTIR) technique to understand changes in the chemical structure in Padina tetrastromatica (Hauck). The marine brown alga under study was grown in two different environmental conditions; in natural seawater (P. tetrastromatica (c)) and in seawater suplemented with 50 ppm of c...
متن کاملMetal Concentrations in Padina Species and Associated Sediment from Nayband Bay and Bostaneh Port, Northern Coast of the Persian Gulf, Iran
The status of metal concentrations including Pb, Cd, Cu, Ni, Zn and Fe in six species of Padina were determined in polluted (Nayband Bay) and unpolluted (Bostaneh port) areas on the Coast of the Persian Gulf. The mean concentrations of metals in the sediment of two locations were: Pb (12.64), Cd (3.59), Cu (21.74), Ni (17.00), Zn (32.00) and Fe (677.53) µg g-1 dry weight, respectively. In ...
متن کاملAntioxidant Activity and Gas Chromatographic-Mass Spectrometric Analysis of Extracts of the Marine Algae, Caulerpa peltata and Padina Gymnospora
The results of our previous investigations on extracts of selected marine algae showed that Caulerpa peltata and Padina gymnospora had more promising antiproliferative and antioxidant activities than Gelidiella acerosa and Sargassum wightii. Based on these results, the more active chloroform extract of C. peltata and ethyl acetate extract of P. gymnospora were further analyzed for their constit...
متن کاملPurification of silver and gold nanoparticles from two species of brown seaweeds (Padina tetrastromatica and Turbinaria ornata)
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...
