However, despite the low phenolic content of SmEE, this extract showed DPPH radical scavenging activity, as reported for Sargassum muticum (Kim et al, 2007), other crude extracts from Sargassum sp and purified phlorotannins (Ye et al, 2009;Balboa et al, 2013). The TEAC value of algal extracts was considerably lower than those presented by benzoic acid and cinnamic acid rich extracts.…”

“…The TEAC value of algal extracts was considerably lower than those presented by benzoic acid and cinnamic acid rich extracts. However, other authors reported important ABTS radical scavenging capacity activity of solvent extracts from algae (Ayyad et al, 2011;Balboa et al, 2013). The reducing power was high both for the phenolic rich extracts and for fucoidan rich extracts; the reducing capacity of crude polysaccharides and fucoidan from brown algae is well known (Rupérez et al, 2002;Chattopadhyay et al, 2010).…”

“…Phlorotannins are phenolic compounds exclusive of marine seaweeds, but these organisms, particularly brown algae, also contain a variety of components with antioxidant action (such as polyunsaturated fatty acids, proteins, pigments, vitamins, polysaccharides and carotenoids). The phlorotannins and algal polysaccharides exhibit anticoagulant, antiviral, antioxidative, anticancer, antiinflammatory and immunomodulatory actions, and could have potential for the development of nutraceutical, pharmaceutical and cosmeceutical products (Batista González et al, 2009;Balboa et al, 2013;Thomas and Kim, 2013). Valorization and utilization of the constituents of the brown macroalga Sargassum muticum was proposed, since the solvent extracts (Kim et al, 2007) and the soluble fractions obtained after autohydrolysis (González-López et al, 2012) were active in vitro antioxidants.…”

The performance of natural extracts obtained from underutilized and residual vegetal and macroalgal biomass processed with food-grade green solvents was compared with that of commercial antioxidants. Selected extracts were obtained from two terrestrial sources: winery byproducts concentrate (WBC) and chestnut burs hydrothermally fractionated extract (CBAE), and from two underutilized seaweeds: Sargassum muticum extracts, either extracted with ethanol (SmEE) or after alginate extraction and hydrothermal fractionation (SmAE) and from Ulva lactuca processed by mild acid extraction and membrane concentration (UlAE). These extracts showed in vitro antioxidant properties comparable to commercial antioxidants and were safe for topical use based on the absence of skin-irritant effects at 0.1% on reconstructed human tissues. The stability of several cosmetic model emulsions was assessed during accelerated oxidation assays. The incorporation of natural extracts produced from renewable underutilized resources at 0.4-0.5% in an oil in water emulsion reduced lipid oxidation during storage.

“…In vitro antioxidant action is used as a first tool to select potential compounds for protection from lipid oxidation and for further formulation of functional feeds (Balboa et al, 2013). DPPH is a stable free radical widely used for evaluating natural antioxidants (algae or algal products) (Kang et al, 2003;Kuda et al, 2007) due to its stability, simplicity and reproducibility.…”

ABSTRACT. Water-soluble extracts from seaweeds Macrocystis pyrifera (M) and Undaria pinnatifida (U) were prepared to use the polysaccharide bioactive fraction as functional food. Chemical analysis showed that the main components of both extracts were mannitol and fucoidans. Also in both cases minor amounts of rhamnose, glucose, xylose and arabinose were determine. Content of fucose+galactose was higher in U. pinnatifida (8.7%) than in M. pyrifera (5.9%). Extracts were used as feed additive to Artemesia longinaris at inclusion levels of 1 and 2% (M1 and M2; U1 and U2), a diet without extract was used as control. Radical scavenging activities were estimated for two extracts and for midgut gland samples of experimental animals. Scavenging activity was detected in both extracts, the signal decayed to 50 and 62% in 18 min for U. pinnatifida and M. pyrifera, respectively. After 30 days of feeding, results did not show variation of survival, but growth was improved in animals fed with U1 and U2. Supplementation with 1 and 2% of U. pinnatifida showed similar quenching capacity of homogenates than those fed with M2 with a rapid 1,1-diphenylpicrylhydrazyl (DPPH) decay at 2 min of reaction. Recommended concentration for culture A. longinaris is 2%, as it is that produce the best antioxidant capacity, although the growth performance was improved also significantly only with U. pinnatifida extract.
