1. Comparative assessment of antioxidant activity and biochemical composition of four seaweeds, Rocky Bay of Abu Qir in Alexandria, Egypt
Abstract The current study estimated the antioxidant activity and biochemical composition of four seaweeds; Toania atomaria (Phaeophyta), Padina pavonia (Phaeophyta), Jania rubens (Rhodophyta) and Corallina elongate (Rhodophyta). The highest total antioxidant activity was observed with ethanol extract of T. atomaria (44.6 ± 1.6 mg ascorbic acid equivalents/

2. In vitro potential activity of some seaweeds as antioxidants and inhibitors of diabetic enzymes
Abstract In this study crude extracts of Turbinaria decurrens, Padina pavonica, Sargassum muticum and Sargassum acinarium (Phaeophyta); Ulva lactuca (Chlorophyta) and Pterocladia capillacea (Rhodophyta) seaweeds were tested to evaluate their antioxidant properties and antidiabetic potential on α-amylase and α-glucosidase starch hydrolyzing enzymes. The res

3. A review of common parameters and descriptors used in studies of the impacts of heavy metal pollution on marine macroalgae: identification of knowledge gaps and future needs
ABSTRACT This study presents a systematic review to assess the main similarities and gaps in efforts to evaluate the impacts of heavy metals on benthic marine seaweeds. A total of 91 studies were compiled, the main parameters (abiotic, biological, ecotoxicological, and heavy metals) and descriptors of which were evaluated by quantitative and qualitative ana

6. Potency of nano-antibacterial formulation from Sargassum binderi against selected human pathogenic bacteria
Seaweeds constitutes an abundant marine reserve that can be harnessed as source of new pharmaceutical agents. Sargassum binderi Sonder ex J. Agardh is a brown seaweed that is predominantly available from December to March in the Red Sea, Jazan, Kingdom of Saudi Arabia (KSA). In this study, three extracts were isolated using three different techniques, and we

7. An overview of odoriferous marine seaweeds of the Dictyopteris genus: insights into their chemical diversity, biological potential and ecological roles
ABSTRACT Since the middle of the twentieth century the marine algae have attracted attention as a source of new drugs. Dictyopteris is an important group of marine seaweeds and is widely distributed in tropical, subtropical and temperate regions. This genus is known by its characteristic “ocean smell”. Some species show a distinct phytochemistry, with sp

8. Biochemical composition of some Egyptian seaweeds with potent nutritive and antioxidant properties
Abstract The present study investigated the biochemical composition of three seaweeds; Ulva fasciata (Chlorophyta), Sargassum linifolium (Phaeophyta) and Corallina officinalis (Rhodophyta). Total chlorophyll content was maximum in U. fasciata (34.06mg/g dry wt.) while carotenoid content was the highest in C. officinalis (3.8 mg/g dry wt.). The uppermost leve

9. Seasonal influence of drifting seaweeds on the structure of fish assemblages on the eastern equatorial Brazilian coast
Resumo O presente estudo comparou assembleias de peixes em duas áreas adjacentes, uma com algas à deriva (A) e outra ausente de algas (WA), a fim de avaliar as mudanças sazonais na sua diversidade e composição. Ambas as áreas estão localizadas na praia de São Cristóvão, Rio Grande do Norte, na região semiárida, costa Norte-Nordeste do Brasil. Um

10. Brown seaweed Padina gymnospora is a prominent natural wound-care product
ABSTRACT Seaweeds are related to anti-inflammatory, anti-bacterial and anti-noceptive effects. This work aimed to verify the potential of seaweed Padina gymnospora (Kützing) Sonder 1871 to improve wound healing in vitro. P. gymnospora was collected at a bethonic area in Espirito Santo. Methanolic extract of P. gymnospora was obtained by percolation. To dete

11. Antimicrobial (including antimollicutes), antioxidant and anticholinesterase activities of Brazilian and Spanish marine organisms – evaluation of extracts and pure compounds
Abstract This work describes the antimicrobial, antioxidant and anticholinesterase activities in vitro of organic extracts from fourteen seaweeds, eleven sponges, two ascidians, one bryozoan, and one sea anemone species collected along the Brazilian and Spanish coast, as well as the isolation of the diterpene (4R, 9S, 14S)-4α-acetoxy-9β,14α-dihydroxydolas

12. Antischistosomal activity from Brazilian marine algae
Abstract Schistosomiasis may be caused by six different species of the genus Schistosoma. Current treatment is based only on two drugs: oxamniquine, which is only effective against the Schistosoma mansoni species, and praziquantel, which is ineffective against young parasites. Therefore, research on new drugs and their targets for the treatment of this disea
