“…Fourier-transform IR spectroscopy and elemental analysis indicated that the purified SPS-CF is an SP containing significant amounts of sulfate esters (5.7% in mass). The monosaccharide composition of this glucuronogalactomannan was fairly different from that reported by Karnjanapratum et al [146], who found that sulfated mannans exist in C. fulvescens. In Karnjanapratum’s study, three polysaccharide fractions (F1, F2, and F3) were isolated from C. fulvescens by water extraction and ion-exchange chromatography.…”

Among the three main divisions of marine macroalgae (Chlorophyta, Phaeophyta and Rhodophyta), marine green algae are valuable sources of structurally diverse bioactive compounds and remain largely unexploited in nutraceutical and pharmaceutical areas. Recently, a great deal of interest has been developed to isolate novel sulfated polysaccharides (SPs) from marine green algae because of their numerous health beneficial effects. Green seaweeds are known to synthesize large quantities of SPs and are well established sources of these particularly interesting molecules such as ulvans from Ulva and Enteromorpha, sulfated rhamnans from Monostroma, sulfated arabinogalactans from Codium, sulfated galacotans from Caulerpa, and some special sulfated mannans from different species. These SPs exhibit many beneficial biological activities such as anticoagulant, antiviral, antioxidative, antitumor, immunomodulating, antihyperlipidemic and antihepatotoxic activities. Therefore, marine algae derived SPs have great potential for further development as healthy food and medical products. The present review focuses on SPs derived from marine green algae and presents an overview of the recent progress of determinations of their structural types and biological activities, especially their potential health benefits.

Among these factors, the variation in their proximate compositions seemed to be largely influenced by the species differences.…”

Sulfated polysaccharides (SP) isolated from freshwater green algae, Spirogyra neglecta (Hassall) Kützing, and fractionated SPs were examined to investigate their molecular characteristics and immunomodulatory activity. The crude and fractionated SPs (F1, F2, and F3) consisted mostly of carbohydrates (68.5–85.3%), uronic acids (3.2–4.9%), and sulfates (2.2–12.2%) with various amounts of proteins (2.6–17.1%). d-galactose (23.5–27.3%), d-glucose (11.5–24.8%), l-fucose (19.0–26.7%), and l-rhamnose (16.4–18.3%) were the major monosaccharide units of these SPs with different levels of l-arabinose (3.0–9.4%), d-xylose (4.6–9.8%), and d-mannose (0.4–2.3%). The SPs contained two sub-fractions with molecular weights (Mw) ranging from 164 × 103 to 1460 × 103 g/mol. The crude and fractionated SPs strongly stimulated murine macrophages, producing considerable amounts of nitric oxide and various cytokines via up-regulation of their mRNA expression by activation of nuclear factor-kappa B and mitogen-activated protein kinases pathways. The main backbone of the most immunoenhancing SP was (1→3)-l-Fucopyranoside, (1→4,6)-d-Glucopyranoside, and (1→4)-d-Galactopyranoside.

“…This green alga has been widely used in the food industries, as well as in cosmetics and pharmaceutical industries due to its beneficial effects on the human immune system and various health-enhancing properties (1,2). Recently, CF has attracted attention due to its potential use in foods, cosmetics, and pharmaceuticals, and its powder has been successfully used in the processing of sponge cakes (3), white pan breads (4), tofu (5), rice noodles (6), and cookies (7).…”

ABSTRACT:The moisture sorption isotherms of vacuum-dried edible green alga (Capsosiphon fulvescens) powders were determined at 25, 35, and 45 o C and water activity (aw) in the range of 0.11∼0.94. An inversion effect of temperature was found at high water activity (＞0.75). Various mathematical models were fitted to the experimental data, and Brunauer, Emmett, and Teller model was found to be the most suitable model describing the relationship between equilibrium moisture content and water activity (＜0.45). Henderson model could also provide excellent agreement between the experimental and predicted values despite of the intersection point. Net isosteric heat of adsorption decreased from 15.77 to 9.08 kJ/mol with an increase in equilibrium moisture content from 0.055 to 0.090 kg H2O/kg solids. The isokinetic temperature (T) was 434.79 K, at which all the adsorption reactions took place at the same rate. The enthalpy-entropy compensation suggested that the mechanism of the adsorption process was shown to be enthalpy-driven.
