“…Phenols have been identified in several algal species as biologically active compounds (Vairappan, et al, 2001). Many compounds of marine algae show anti-bacterial activities as polysaccharide (Laurienzo, 2010), lyengaroside (Ali et al, 2002), polyhydroxy lated fucophlorethol (Sandsdalen et al, 2003), bromophenols (Oh et al, 2008), guaiane sesquiterpene (Chakraborty & Lipton, 2010), lactone malyngolide (Cardelina et al, 1979) cycloeudesmol (Sims et al, 1975), polyphenolic compound (Devi, 2008), halogenated compound (Vairappan, 2003) and quinone metabolite (Horie et al, 2008). Flavonoids comprise a large group of naturally compounds widely distributed in the algae and some of these compounds have been reported to contain various and potent biological activities including anti oxidative tissue protective and tumoristatic effects as well as the inhibition of hepatic cholesterol biosynthesis (Krant et al, 2005;Kim et al, 2007;Matanjun et al, 2008 andVolk, 2009).…”

MARINE algae contain a variety of bioactive secondary metabolites and several compounds have been derived from them for prospective development of novel drugs by the pharmaceutical industries. In this laboratory experiment Cystoseira barbata was isolated from Red Sea coastal water (Safaga, Egypt). It was evaluated due to its bioactivities potential. Where the algal extract proved a potent activity against bacterial and fungal strains ranged between medium and high suppression action. It showed that Gram positive bacteria Bacillus subtilis and Staphylococcus aureus were more sensitive than Gram negative bacteria where Serratia marcescens, Pseudomonas aeuroginosa and fungus Candida albicans. Phyto-chemical analyses showed that C. barbata recorded the highest percentages of the flavonoids, phenols and saccharides compounds. Among the bioflavonoids determined Acacetin, Kaemp.3-(2-pcomaroyl) glucose, Rosmarinic and phenols were E-Vanillic, Benzoic and Ferulic were present in high percentages in the alga analyzed. The results indicated scope for utilizing this alga as a source of antibacterial and antifungal substances.

“…Algal cells cope with environmentally promoted generation of ROS through induction of catalase and ascorbate peroxidase, massive H 2 O 2 diffusion out into the water and synthesis of volatile halocarbons (Collen & Pedersen, 1996;Barros et al, 2003). Toxicity is also reduced through decomposition and scavenging of H 2 O 2 by antioxidants which are abundant in many species of seaweeds (Devi et al, 2008). In Ulva rigida, the main enzymatic method of H 2 O 2 removal is through peroxidative scavenging (Collen & Pedersen, 1996;Ross & Van Alstyne, 2007).…”

Cell culture technology is immensely useful in somatic hybridization, induction of mutations, cloning of specific isolates and maintenance of strains of defined genotypes. However, its application in strain improvement of some tropical red macroalgae has been limited due to the difficulty of isolating viable cells from their complex intercellular matrices. A simple, non-enzymatic technique of isolating somatic cells was developed for Kappaphycus spp. and Echeuma denticulatum. Surface-sterilized tissues (0.1 g fresh weight, 2.0 mm thick discs) from subcortical and medullary layers were treated with 3% NaOH, 3% KOH, or hydrogen peroxide in phosphate buffer solution (PBH 2 O 2 ). Tissues of K. alvarezii treated with PBH 2 O 2 softened after 5 h of treatment and completely dissociated after 12 h. Viable cell counts (VCC), determined through staining with Evan's blue, were significantly higher (2.4 × 10 5 cells g −1 fresh weight tissue) in K. alvarezii ('tambalang' strain) treated with PBH 2 O 2 compared with tissues treated with carrageenase from a marine bacterium.

As part of our ongoing alternative medicine program, we have directed our attention toward the identification of edible seaweeds in Korea. Here we report on the anti-inflammatory activities of Ecklonia stolonifera. The present study was undertaken to elucidate the pharmacological and biological effects of E. stolonifera extracts on the production of inflammatory mediators in macrophages. The results indicate that the hexane fraction of E. stolonifera extract (ESH) is an effective inhibitor of lipopolysccharide (LPS)-induced NO, prostaglandin E2, and proinflammatory cytokine production in RAW 264.7 cells. These inhibitory effects of ESH were accompanied by decreases in the expression of inducible nitric oxide synthase and cyclooxygenase-2 proteins. Furthermore, ESH inhibited the LPS-induced phosphorylation and degradation of IκB-α, which is required for the nuclear translocations of the p50 and p65 nuclear transcription factor kappa-B (NF-κB) subunits in RAW 264.7 cells. Our results suggest that ESH might exert an anti-inflammatory effect by inhibiting the expression of pro-inflammatory cytokines. Such an effect is mediated by a blocking of NF-κB activation, which consequently inhibits the generation of inflammatory mediators in RAW264.7 cells. Through HPLC fingerprinting of the E. stolonifera extract, the phloroglucinol was also identified and quantified as standard substance. Moreover, we tested the potential application of E. stolonifera extract as a cosmetic material by performing human skin primary irritation tests. In these assays, E. stolonifera extracts did not induce any adverse reactions. Based on these results, we suggest that E. stolonifera extracts be considered possible anti-inflammatory candidates for topical application.
