Know More. Ingredients: Purified Water, Ecklonia Maxima Extract, glucose, glucose oxidase, lactoperoxidase, citric ⦠Absolute stereochemistry in this series was established from studies with (24) as isolated from the Oregon alga E. menziesii through selective opening of the epoxide at C-13, formation of the corresponding bis( p-bromobenzoate), and characterization by circular dichroism spectroscopy.54 The 12,13-diols were subsequently isolated as natural products of E. stolonifera.55 From the Oregon alga, an obviously related series of compounds was discovered—the egregiachlorides (e.g., (25))—in which a chloro functionality rather than the attachment of the lactone is found at the ω3 position.56 Finally, an ω2 olefin analogue of the egregiachlorides (26) was also characterized in this latter study. cosmetic ingredient for skin conditioning: Recommendation for ecklonia maxima extract usage levels up to: not for fragrance use. The quest begins to develop an effective, cellular level extraction technology to access the active elements A new technology. In 1975 the brown seaweed, Ecklonia maxima, is identified as having beneficial effects on plant growth. HAZARDS IDENTIFICATION As the investigations suggest that MMP-2 (Gelatinase-A) and MMP-9 (Gelatinase-B) can degrade type IV collagen of base membranes and are known to play a crucial role in cancer invasion such as oral carcinoma and other cancers (Ikebe et al., 1999) and that these enzymes play a major role in cancer metastasis (Nagase et al., 1998), the MMP downregulation effect of phlorotannins and polyphenolic compounds from marine brown algae stands more promising and recommending them as potential medicinal foods to combat metastasis. It has been established that oxidative damage occurs in different pathologies including diabetes, and diabetic models can be used as a tool to establish antioxidant activities. (2011) have also studied on the photoprotective effect of dieckol from E. cava using human epithelial keratinocytes (HaCat) and have found that dieckol treatment (100 μM) on UVB irradiated cells induces the cell survival up to 88.42%. Skin wrinkling is normally attributed by the reactive oxygen species (ROS) which is caused by the oxidative stress. To be used as often as required. Fig. Macrocystis pyrifera has been considered the dominant species of subtidal kelp communities along the Chilean coast (Fritsch, 1945; Mann, 1973; Michanek, 1979), which, however, is only true south of 42°S. Regular intake of antioxidants would be an useful strategy to combat UVB induced photodamage. In addition, this review highlights that species mainly devoted to direct human food have been investigated. The level of ALP, osteocalcin, and BMP-2 were increased in the presence of fucoidan. (2011) evaluated the antiatherogenic effect of hydrophilic extracts and phenolic-rich fractions from H. incrassata using Apo E −/− mice on a high fat diet, which was supplemented with 550 mg lyophilized seaweed/kg/day for 8 weeks. S. japonica is widely eaten in Japan and China, and to a lesser extent in the Republic of Korea. Ecklonia maxima, Koppie Alleen, De Hoop, 2010. (2010) determined the structure of fucoidan extracted from brown algae U. pinnatifida and concluded that this fucoidan is sulfated galactofucan containing β-d-galactopyranose and α-l-fucopyranose at near equal amounts (44.6 and 50.9 mol%). Other substituents, such as O-acetyl, and branches are present in all these fucoidans and add considerably to their heterogeneity. Calcium level contributes to be crucial in the strengthening of bone and bone homeostasis. L. nigrescens grows in thick belts in the rocky lower eulittoral zone, where its massive holdfast allows it to survive the rough waters in which it thrives. Phlorotannins from Ecklonia maxima1. Although fucoidan was extracted from the numerous species of brown algae (Table 33.1), to the best of our knowledge, there are a few reports on beneficial effects of fucoidan on bone health or formation. Because alginate was first discovered by E.C.C. Ascophyllum is found in cold waters of the Northern Hemisphere. 33.3). Laminaria is found in many areas of the world, principally on the North Atlantic coast of both hemispheres and along the coasts of Japan and China. Fig. High in naturally occurring iodine and other trace elements and minerals, ecklonia maxima pulls toxins from the skin and may decrease some swelling. Active ingredient. Heo et al. High-level aflatoxin exposure produces acute hepatic necrosis, subsequently resulting in cirrhosis, and/or carcinoma of the liver. Biomass production of natural beds in the tropics is largely unknown but can reach 15.6 kg/m2 (wet weight) in the Philippines (Marquez et al., 2014). The potential of ecklonia maxima for the skin was discovered by Dr Nigel Christie, a British scientist who was studying at the University of Cape Town at the time, where he was completing his PhD in marine biology. They derive their characteristic brown color from the large amounts of the carotenoid fucoxanthin contained in their chloroplasts and the presence of various phaeophycean tannins. Durvillaea is found only in the Southern Hemisphere and grows best in rough water, near the top of the sublittoral zone, on rocky shores or offshore reefs. She is known worldwide as The Cosmetics Cop and creator of Paulaâs Choice Skincare. In vitro studies on methanol extract from marine alga Corallina pilulifera (CPM) have revealed that CPM has the ability to prevent UV-induced oxidative stress and also the expressions of MMP-2 and MMP-9 in HDF cells. It is suggested that formation of phlorotannins is by polymerization of phloroglucinol (1,3,5-trihydroxybenzene) monomer units and biosynthesized through the acetate–malonate pathway, also known as polyketide pathway. Table 8.1. 33.2. Also known as brown algae or brown seaweed, ecklonia cava has been linked to some powerful health benefits to its high levels of antioxidants, anti-inflammatories, and phloroglucinols. Oxidative stress is considered to be a causal factor in atherosclerosis progression. L. hyperborea is also found on the west coast of Ireland, the Outer Hebrides, and the Orkney Islands in Scotland. The alginate content is usually low compared with the previously listed genera, and the quality of the alginate is poor. Phlorotannins are oligomeric compounds using phloroglucinol (1,3,5-trihydroxybenzene) as a basic unit. M. pyrifera is harvested from offshore beds that stretch from Monterey in California, United States, to Bahia Asuncion in Baja California Sur, Mexico. Ecklonia Maxima Seaweed & Botanicals. These results suggested that the compounds help to stimulate the osteoblast differentiation at various stages and further confirmed that these compounds might have a therapeutic potential for the patients with osteoarthritis by stimulating production of proteoglycan. S. japonica is next to Kappaphycus and Eucheuma in terms of total biomass produced in 2012 (∼5.68 million tons), while U. pinnatifida is fourth with 2.14 million tons (FAO, 2014a). Pharmacokinetic properties. A topical composition includes an amount of a concentrate derived from Ecklonia maxima (sea bamboo) effective for treating the skin, hair and/or nails and a dermatologically acceptable carrier. Minh Hong Thi Nguyen, ... Se-Kwon Kim, in Advances in Food and Nutrition Research, 2011. In addition, the phlorotannin derivatives could attenuate inflammatory response via MAPK pathway in chronic articular diseases. About the Experts. The resultant hydroperoxide has been proposed to subsequently rearrange to an EAC that leads to cyclopentyl ring formation and an ω3 carbocation.45 The metabolic fates of this carbocation, as observed through these natural product isolations, include trapping with the carboxylate to form the macrolactone of the ecklonialactones (e.g., (24)), trapping with chloride to form the egregiachlorides (e.g., (25)), or loss of an ω2 proton to make the ω2 olefin (26) (Scheme 6). Experimental cultivation of Ecklonia in South Africa has been successful, with growth of young plants on rafts. Further, they have studied this promising photoprotective effect of dieckol using zebrafish as an alternate animal model system. By the examination of 1H and 13C NMR data, it was found that the structure of the compound is similar to that of trimeric phlorotannin triphlorethol-A (Fig. In stock / Shipping Available. The SEANOL ®-brand Ecklonia cava Extracts such as SEANOL ®-P (a.k.a., SEAPOLYNOL ®) and SEANOL ®-F are rich in special class of health-supporting phlorotannins called "eckols". In France, it is in the upper sublittoral zone and is harvested around the coast of Brittany and adjacent islands. By the mid-1990s, production had started to rise and the reported harvest in 1999 was 4,500,000 wet tonnes. Chinese producers now account for the majority of alginate products in the global market. Pack size: 25g. ROS levels were measured using image analysis and fluorescence micrographs, and dieckol has also shown a typical fluorescence micrograph of the nonirradiated zebrafish. It is a well-understood fact that marine flora harbors a wide range of biologically active compounds that are reported to have an outstanding prospective in the medicinal, nutraceutical, and cosmeceutical applications. Yan et al. Ascophyllum nodosum, which has a total biomass of 159,000 tons in southern New Brunswick in the Atlantic part of Canada, is also harvested from the wild, albeit with an exploitation limit of 17% of the total biomass (Ugarte et al., 2006). Raghavendran, ... S. Rekha, in Functional Ingredients from Algae for Foods and Nutraceuticals, 2013. In exposed coastal regions, L. trabeculata is the dominant community component of the subtidal rocky bottom between Arica (18°S) and Chiloe (42°S), growing at depths between 0 and 20 m (Villouta and Santelices, 1984; Vasquez, 1989). L. digitata grows in the upper sublittoral zone in rocky, wave-exposed localities, and it is well adapted to this because of its flexible stipe and divided blades. Unlike other species of brown seaweeds, which thrive in cold water, Sargassum species are found worldwide in warm temperate and tropical water temperature regions. Therefore, antioxidative therapeutics have great demand to act against free radicals. Common structures in fucoidans from brown algae. (2007). In the latter, the species often occurs in bloom, forming thick mats on reef flats. Two phlorotannins namely dieckol and 1-(3′,5′-dihydroxyphenoxy)-7-(2′,4′,6′-trihydroxyphenoxy) 2,4,9-trihydroxydibenzo-1,4,-dioxin isolated from the methanol extract of marine brown alga, Ecklonia cava, have been reported to suppress both the protein and gene expression levels of MMP-1, MMP-3, and MMP-13 in human osteosarcoma cells (MG-63). In brown algae, this antioxidant protection encompasses mainly by phlorotannins (Yan et al., 1996). 33.1). A detailed account of the various biological activities including free radical scavenging activity of phlorotannins from Ecklonia species has been reported earlier. (2003) studied the fucoidan derived from brown algae and other common fucoidans (Fig. One product currently being marketed is prepared from the stipes of Ecklonia maxima from South Africa . After successfully developing kelp-based products for use in agriculture, he discovered that sea kelp could have benefits for skin too. Unregulated production of free radicals in the cellular systems is responsible in causing cellular damage by oxidizing macromolecules, DNA, proteins, and lipids in the cell. In tropical waters, Sargassum spp., relatives of kelps, are famous for the extensive beds that they form and are often the highest biomass producers, growing as long as more than a meter high. Nevertheless, Marquez et al. In Norway, L. digitata grows in masses at the lower end of the eulittoral zone and was previously an important source for the Norwegian alginate industry. Ecklonia . It soothes red irritated skin⦠Dieckol from marine brown alga, E. cava, has been reported to suppress LPS-induced production of nitric oxide (NO) and prostaglandin E2 (PGE2) and expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in murine BV2 microglia, thus establishing dieckol as a potent anti-inflammatory and neuroprotective agent (Jung et al., 2009). The potential antioxidant activities of three phlorotannins (phloroglucinol, eckol, and dieckol) purified from E. cava is reported to exhibit notable radical scavenging activities; in particular, eckol has been found to exhibit a superior scavenging activity for free radicals and inhibit DNA damage. As shown in Table 8.1, most of the phlorotannin compounds have shown more potent antioxidant activities than commercially available antioxidants α-tocopherol, butylated hydroxyl-anisole (BHA), butylated hydroxytoluene (BHT). It is also worth noting that U. pinnatifida is considered to be an invasive species in many areas, including the Mediterranean Sea, Atlantic Europe, Argentina, Australia, and New Zealand, among others (IUCN, 2009; Pickering et al., 2007; Trowbridge, 2006; Zemke-White and Smith, 2006). Harvest of wild brown seaweeds in 2014. Rothman et al. By continuing you agree to the use of cookies. It grows in parts of Asia. Ecklonia grows in South Africa, and Laminaria digitata is mainly from France and Iceland. Ecklonia Cava is a type of seaweed which is known to be one of the highest sources of phloroglucinols, a type of antioxidant compound that appears to be unique to sea plants. Distribution of wild brown seaweeds around the world. Diphlorethohydroxycarmalol and 6,6-bieckol isolated from Ishige okamurae (Zou et al., 2008); fucodiphloroethol G and dieckol isolated from Ecklonia cava (Li et al., 2009) have shown of 77.2%, 78.9%, 75.6%, and 84.3% ROS inhibition at 50 μM, respectively, in H2O2-induced RAW264.7 cells. Consequently, no work has yet been reported on the antiallergic capacity of seaweeds outside Asia, or on other structural groups of algal phenols, including phlorotannins like fucols, phlorethols, or fuhalols. Since the 1980s, major change in the alginate industry took place with the emergence of producers in China, initially in the production of low-cost, low-quality alginate for the local industrial markets from locally cultivated Saccharina japonica. As it is evident that unregulated expression of MMPs leads to the photoaging, many research groups are emphasizing their research goals to check the ability of marine-derived phlorotannins as potential antiphotoaging agents. In this process of screening the medicinally valuable agents from marine seaweeds, phloroglucinol, a monomer of phlorotannins, is reported to exhibit anti-inflammatory effect in addition to free radical scavenging activity. This clearly suggests the role of phenolic compounds from marine algae as potential MMPIs (Ryu et al., 2009a). This in vitro study has revealed the MMP-2 and MMP-9 inhibitory activities in HT1080 cells, thus suggesting the potentiality of phloroglucinol as an antimetastatic compound. Quantity in pack: 1. Ecklonia maxima, De Hoop specimen showing the hollow stipe typical of this species. (A) Laminaria hyperborea; (B) Ascophyllum nodosum; (C) Macrocystis pyrifera; (D) Lessonia nigrescens; (E) Laminaria digitata; (F) Saccharina japonica; (G) Ecklonia maxima. This UVB radiation induces the overproduction of ROS which interacts with cellular DNA, proteins, and lipids to alter their cellular functions (Heo et al., 2010). PubMed:A molecular investigation of the genus Ecklonia (Phaeophyceae, Laminariales) with special focus on the Southern Hemisphere. Rich in alginates, amino acids, enzymes and vitamins, ecklonia maxima sea kelp helps to hydrate skin. Two other kelp species belonging to the genus Ecklonia (i.e., E. cava and E. stolonifera) are also being subjected to culture development in Korea. Raw material: Fresh material from Ecklonia maxima 34.26% Additives: Preservatives and inert materials 65.74% 3. The gelatinases that include MMP-2 and MMP-9 promote UV-induced skin damage. Copyright © 2020 Elsevier B.V. or its licensors or contributors. and contains a variety of compounds that play diverse biological and ecological roles. Moreover, Kang et al. (B) The 3-linked, preponderantly 4-sulfated fucoidan from E. kurome.
