In this study, the antioxidant activities, total polyphenolic contents of algal extracts from Gongolaria barbata were examined by using ethyl acetate (AcOEt), water(W), and phosphate buffer (PH) as solvents. According to results, EtOH, W, PB showed medium potential with low IC50 values. The highest flavonoid content was detected in W (6.91±0.09 mg/g Ext., maximum phenolic (2.29±0.01 mg GAE/g ex...

The analysis of fucoxanthin (FCX) in algal biomasses presents some limitations, especially regarding the sample preservation after collection until extraction pigment. FCX stability was evaluated biomass samples one diatom and three brown seaweed species (Phaeophyceae) their extracts stored at -20ºC -80ºC, for 60 days. Fucoxanthin quantified through UHPLC-DAD. methanolic micro/macroalga -80ºC w...

Conceived as a baseline for the management and conservation of marine protected area French Southern Territories (réserve naturelle nationale des Terres australes françaises), checklist macroalgae Kerguelen Islands was updated based on an extensive review literature scientific databases, from first report Ross expedition, in 1840, to most recent works. This work also conceived starting point fo...

Taxonomic study of the genus Padina (Dictyotales, Phaeophyceae) from the Persian Gulf coast was conducted based on morphology and molecular phylogenetic analyses using chloroplast encoded large subunit RuBisCo (rbcL) gene sequences. Detailed descriptions of each species found in this study are described. Several morphological characters, such as number of cell layers composing the thallus, pr...
