Comparative assessment of antioxidant activity in three edible species of green seaweed, Enteromorpha from Okha, Northwest coast of India

<b><i>In vitro</i> evaluation of antioxidant activity of methanolic extracts obtained from seaweeds endemic to the coast of Ceará, Brazil

“…Statistical significance was, however, observed in all tested concentrations (p < 0.05) among all algal species based on individual absorbance. On the other hand, results of reducing power reported here are much lower than those cited for a variety of seaweeds, such as Enteromorpha compressa (Ganesan et al, 2011), Kappaphycus alvarezii , and Turbinaria conoides (Devi et al, 2011).…”

“…The extracts of three species of green marine algae (Enteromorpha compressa, E. linza and E. tubulosa), at the concentration of 200 μg mL -1 , showed FIC of approximately 15% (Ganesan et al, 2011). Similar results were observed in the present study, but with 2 to 16 times less concentrated methanolic extracts.…”

“…However, the use of these products has been restricted because they are now suspected of having carcinogenic effects (Kumar, Ganesan, & Rao, 2008). As a result, interest in naturally occurring antioxidants from bioresources, such as seaweeds, has received considerable attention during the last few years, as they are generally believed to be good candidates for the production of safe biologically active substances (Cornish & Garbary, 2010;Ganesan, Kumar, & Rao, 2011;Souza et al, 2011). In marine algae, the Japanese scientists Fujimoto and Kaneda (1980) investigated the presence of potentially antioxidant active substances for the first time.…”

Evaluation of phenolic contents and antioxidant activities of brown seaweeds belonging to Turbinaria spp. (Phaeophyta, Sargassaceae) collected from Gulf of Mannar

“…Several studies demonstrated a significant correlation between the phenolic content and the antioxidant activity in seaweed extracts [16] . It is evident from the present observations that a higher percentage of TPC was observed in the polar solvent fractions (EtOAc and MDC) of Turbinaria spp.…”

Electrochemical Methods for Total Antioxidant Capacity and its Main Contributors Determination: A review

“…The reverse relationship between the consumption of fruits and vegetables and the development of oxidative stress-related disorders, confirmed by epidemiological studies, has been attributed to the presence of compounds endowed with high antioxidant activity [17][18][19][20]. The main biocompounds found in natural sources are phenolics (flavonoids or non-flavonoids), associated to health benefits resulted from the inhibition of low-density lipoprotein oxidation [19,[21][22][23][24][25].…”
