In vitro antioxidant and in vivo anti-inflammatory potential of crude polysaccharide from Turbinaria ornata (Marine Brown Alga)

Effect of a crude sulfated polysaccharide from Halymenia floresia (Rhodophyta) on gastrointestinal smooth muscle contractility

“…These studies suggested that was interesting to investigate this class of macromolecules in animal models (Mourão and Pereira, 1999;Farias et al, 2001;Zhang et al, 2003;Assreuy et al, 2008;Fonseca et al, 2008;Lins et al, 2009;Ananthi et al, 2010), as valuable tools on development of new pharmacological drugs. The anticoagulant activity of marine algae SPs has been widely reported.…”

“…Histopathological analysis of liver and kidney showed that both organs were also moderately affected by C. feldmannii SP treatment (Lins et al, 2009). Recently, a crude polysaccharide from the cell-wall from Turbinaria ornata (Phaeophyta) presented in vivo anti-inflammatory activities (Ananthi et al, 2010). Halymenia floresia (Clemente) C. Agardh is a red marine algae belonging to the Halymeniaceae family, found at Mucuripe Beach, coast of Ceará State, Brazil.…”

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

“…Trichloracetic acid (TCA), 1, 1-dipheny1-2-picrylhydrazyl, 2-thiobarbituric acid, Ferrozine, Folin-Ciocalteu reagent, 2, 2′-azino-bis-(3ethylbenzothiozoline-6-sulfonic acid diammonium salt), Trolox (6- 1 to obtain the clarified filtrates (1.8 L), which were filtered, through Na 2 SO 4 (150 g), and evaporated (40 °C) using rotary evaporator under vacuum to dryness to give a dark green viscous oily mass (100 mL) of methanolic fraction. This dark green viscous oily mass (100 mL) of methanolic crude extract was mixed with an equal volume of distilled water (100 mL), and partitioned successively with n-hexane (200 mL伊3), dichloromethane (MDC; 200 mL伊3), and EtOAc (200 mL伊3) to furnish n-hexane (600 mL), MDC (600 mL), and EtOAc fractions (600 mL), respectively.…”

“…Antioxidants are the substances, which can defend serious human diseases including melanoma, cardiac disorders, diabetes mellitus, inflammatory and neurodegenerative diseases [1] that explain their potential use in increasing shelf-life of food and as medicine [2,3] .…”

Clinical Evaluation of Novel Natural Polysaccharides Sacran as a Skincare Material for Atopic Dermatitis Patients

“…Recently, numerous beneficial effects of natural polysaccharides have been demonstrated on human health to exhibit a spectrum of biological activities such as antioxidant, antitumor, and anti-inflammatory [3]- [5]. For example, the heparan sulfate on the surface of all adherent cells modulates the actions of a large number of extracellular ligands [6].…”
