Hong, Yawen published the artcileIsolation, molecular characterization and antioxidant activity of a water-soluble polysaccharide extracted from the fruiting body of Termitornyces albuminosus (Berk.) Heim, HPLC of Formula: 59-23-4, the main research area is Termitomyces fruiting body water soluble polysaccharide antioxidant activty; Antioxidant activity; Polysaccharide; Structure analysis; Termitornyces albuminosus.

A water-soluble polysaccharide WSP1 was extracted from the fruiting body of Termitornyces albuminosus. Its mol. weight, monosaccharide composition and mol. structure were determined by GPC, GC-MS, UV spectroscopy, FT-IR spectroscopy, methylation anal., NMR (1D and 2D) and AFM. Moreover, the antioxidant activity of WSP1 was evaluated in vitro by the tests of reducing power, scavenging ability on DPPH radical and hydroxyl radical, and chelating ability on ferrous ion. The results indicated that the mol. weight of WSP1 was 9 kDa, and it was mainly composed of fucose and galactose in a molar ratio of 1:3.09. Based on monosaccharide composition, methylation anal. and NMR, the possible repeating unit of WSP1 was presented as follows:â†?-α-L-Fucp-1â†?(6-α-D-Galp-1)3â†? The antioxidant assay revealed that, in the concentration range tested in this experiment, WSP1 had strong scavenging ability on DPPH radical, suggesting that WSP1 could be potentially used as a powerful radical scavenger.

Hamed, Mariem published the artcilePolysaccharides extracted from pistachio external hull: Characterization, antioxidant activity and potential application on meat as preservative, Safety of (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is meat Pistacia polysaccharide galactose arabinose antioxidant activity food product.

In the present study, polysaccharides were isolated from pistachio (Pistacia vera L.) external hull, with a yield of 4.10% (weight/weight). The crude polysaccharides were composed by carbohydrates (80.64 ± 0.98%), while protein (1.80 ± 0.28%), ash (6.32 ± 0.26%) and fat (0.04 ± 0.005%) contents were low. Structural characteristics were determined using FTIR spectroscopy and 13C NMR spectroscopy. The results by thin layer chromatog. showed that the carbohydrate fraction was mainly composed of rhamnose, glucose, galactose, mannose, xylose, arabinose, and galacturonic acid. Antioxidant activities of the crude polysaccharides were investigated by various antioxidant assays: DPPH radical-scavenging capacity (IC50 = 0.08 mg/mL), reducing power, β-carotene bleaching inhibition (IC50 = 0.068 mg/mL), and ABTS assay. The application of crude pistachio hull polysaccharides on minced meat, as preservative, reduced the lipid oxidation during chilled storage for 9 days. The obtained results also showed significant improvement of meat color stability. Overall, these findings indicated that crude polysaccharides are worthy being developed as functional and bioactive components for the food and nutraceutical industries.

Alencar, Poliana O. Cavalcante published the artcileA novel antioxidant sulfated polysaccharide from the algae Gracilaria caudata: In vitro and in vivo activities, Recommanded Product: (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Gracilaria sulfated polysaccharide antioxidant activity oxidative stress.

Marine red macroalgae are natural sources of sulfated polysaccharides, water-binding mols. used in the food industry as thickeners, stabilizers and gelling agents. Sulfated polysaccharides extracted from the red seaweed Gracilaria caudata also show biol. activities with potential therapeutic effects against diseases associated with oxidative stress; hence, it is possible that they may be used as nutraceuticals and/or food additives. This study aimed to obtain the sulfated polysaccharides from G. caudata (SP-Gc) through enzymic extraction and to determine their chem. structure and antioxidant potential. Inductively Coupled Plasma-Optical Emission Spectrometry showed that SP-Gc have 0.9% of sulfur atoms and a degree of sulfation of 0.14%. An average mol. mass of 116.51 kDa was determined through gel permeation chromatog. The SP-Gc structure as an agar-type galactan was determined by Fourier transform IR (FTIR) spectroscopy and NMR (NMR) spectroscopy (13C and 1H). The in vitro antioxidant activity of SP-Gc was determined through the following tests: ferrous ion chelating ability and total antioxidant capacity. The results indicated that SP-Gc have significant antioxidant activity in a concentration-dependent manner. The in vivo antioxidant activity of SP-Gc was evaluated in an oxidative stress model induced by 2,2′-azobis(2-methylpropionamidine) dihydrochloride (ABAP) in rats pretreated with SP-Gc (3 and 10 mg/kg). Catalase (CAT) and superoxide dismutase (SOD) levels were measured and all doses increased CAT and SOD activity. These results demonstrate that SP-Gc may be used as hydrocolloids, due to their characterization as agar, and as nutraceuticals, due to their antioxidant activity.

Wang, Li published the artcilePhysicochemical properties and bioactivities of original and Se-enriched polysaccharides with different molecular weights extracted from Pleurotus ostreatus, SDS of cas: 59-23-4, the main research area is pleurotus selenium polysaccharide mol weight bioactivity physicochem property; Antioxidant activity; Different molecular weight; Hypoglycemic activity; Pleurotus ostreatus; Selenium polysaccharides.

Three polysaccharides (WZP1, WZP2, WZP3) and their Se-enriched products (SeWZP1, SeWZP2 and SeWZP3) were obtained from Pleurotus ostreatus using a simple, rapid method and HNO3-Na2SeO3 method, resp. The mol. weight distribution profiles of all samples except SeWZP2 showed double peaks. The average mol. weights (Mw) of WZP1-3 were 48.6 kDa, 20.2 kDa and 11.8 kDa, resp., and of SeWZP1-3 were 19.6 kDa, 37.7 kDa, 14.5 kDa, resp. The complexity of monosaccharide composition of WZP1-3 was inversely proportional to the ethanol concentration used in the ethanol precipitation process. Addnl., the results of biol. activity tests indicated that a-glucosidase inhibitory activity of WZP1-3 was related to the mol. weight and the monosaccharide composition complexity. The selenized modification can improve the a-glucosidase-inhibiting, hydroxyl radical-scavenging activity of P. ostreatus polysaccharides. Therefore, by improving their bioactivities by selenization, the polysaccharides of P. ostreatus could be utilized as a natural health food supplement.

Ji, Xiaolong published the artcileComparison of structural characterization and antioxidant activity of polysaccharides from jujube (Ziziphus jujuba Mill.) fruit, Safety of (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is Ziziphus fruit polysaccharide antioxidant activity; Antioxidant activities; Jujube; Polysaccharide; Structural characterization.

The aim of this paper was to prepare purified fractions of polysaccharides from jujube (Ziziphus jujuba Mill.) fruit and further compare their structural characteristics and antioxidant activities. Firstly, three purified jujube polysaccharides, named PZMP1, PZMP2 and PZMP3, were successfully prepared by DEAE-Sepharose Fast Flow and Sephacryl S-300 columns. Then, their characteristics were studied and then compared by using chem. testing, high-performance gel permeation chromatog. (HPGPC), gas chromatog. (GC), Fourier transform IR spectroscopy (FT-IR), methylation anal., NMR spectroscopy, X-ray diffraction (XRD), SEM (SEM) and at. force microscopy (AFM). Thereafter, their antioxidant activities were also contrasted. The data achieved demonstrated that the three jujube polysaccharides derived from different adsorption capacity of DEAE-Sepharose Fast Flow and Sephacryl S-300 columns possessed different structural characteristics and antioxidant activity, and with higher galacturonic acid content could exhibit better antioxidant bioactivities, which could provide certain directions for the functional and medicinal purposes development of jujube polysaccharides.
