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.

Fucoidan is a complex sulfated polysaccharide and an active component found in the cell wall of brown seaweeds. In the present study, fucoidans were obtained from Sargassum fusiforme using different extraction methods, including hot water (prepared fucoidan was named as WSFF), dilute hydrochloric acid (ASFF), and calcium chloride solution (CSFF). The assessments were performed on S. fusiforme fucoidans based on their chem. composition, mol. conformations, and in vitro antioxidant activities. ASFF showed the maximum extraction yield (11.24%), whereas CSFF exhibited the min. yield (3.94%). The monosaccharide composition of WSFF, ASFF, and CSFF was similar, but the molar ratio of monosaccharide was quite different. Moreover, their mol. weight, Fourier transform IR (FT-IR) spectrum, surface morphol., uronic acid content and degree of sulfation were distinct. The Congo red test and CD spectroscopy anal. displayed some differences in solution conformation of these samples. Furthermore, WSFF, ASFF, and CSFF showed distinct in vitro antioxidant activities evaluated by DPPH and hydroxyl radical scavenging assays. The present study provides scientific evidence on the influences of extraction methods on the physicochem. characteristics, conformation behaviors and antioxidant activities of S. fusiforme fucoidans.
