Wang, Ping-Ping published the artcileThe chemical structure and biological activities of a novel polysaccharide obtained from Fructus Mori and its zinc derivative, HPLC of Formula: 59-23-4, the main research area is Morus hepatoma insulinoma zinc polysaccharide MFP4P.

A novel polysaccharide (MFP4P) was isolated from mulberry fruits (Morus alba L.) pulp using a combination of DEAE-Sepharose fast-flow and Sephadex G-100 chromatog. columns. Structural characterization revealed that MFP4P was composed of arabinose, rhamnose, galactose, glucose and galacturonic acid with a mol. weight of 198.2 kDa. The linkage types of MFP4P were proved to be (1 â†?6)-linked α-D-Glc, (1 â†?2)-linked α-L-Rha, (1 â†?3)-linked α-D-Gal, (1 â†?3)-linked β-L-Rha and (1 â†?)-linked α-L-Ara. The MFP4P showed good antioxidant activity with an oxygen radical absorbance capacity value of 121.8 ± 16.5 μM trolox equivalent/g. In addition, the MFP4P promoted pancreatic cell proliferation, increased insulin secretion, and enhanced glucose consumption. In the non-toxic range, the polysaccharide and zinc complexes (MFP4P-Zn) exhibited higher antioxidant and hypoglycemic activities than MFP4P at the same concentration In vivo hypoglycemic study, MFP4P and MFP4P-Zn both showed decreased blood glucose level and glucose tolerance compared with the model control group.

Liu, Jian published the artcileDifferent extraction methods bring about distinct physicochemical properties and antioxidant activities of Sargassum fusiforme fucoidans, HPLC of Formula: 59-23-4, the main research area is Sargassum fucoidan antioxidant physiochem property; Antioxidant; Fucoidan; Sargassum fusiforme.

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.

Xu, Guan-Yi published the artcileEvaluation of structural, functional, and anti-oxidant potential of differentially extracted polysaccharides from potatoes peels, Safety of (2R,3S,4S,5R)-2,3,4,5,6-Pentahydroxyhexanal, the main research area is potato peel polysaccharide structural functional property antioxidant potential; Anti-oxidant; Differential extraction; Physicochemical; Polysaccharides; Potato peel.

Potato peel was used for the extraction of three types of polysaccharides (PW, PAL, and PAC) using water, alk., and acid treatments, resp. The structure of the PP polysaccharides was examined by means of Fourier transform IR spectroscopy (FT-IR) anal. and Gas chromatog.-mass spectrometry (GC-MS). The results suggest that the extracted polysaccharides constituted essentially three functional groups: C=O, C-H, and O-H. The polysaccharides were comprised of low proportions of proteins, 17-23% uronic acids, and approx. 70% carbohydrates. PAL, PW, and PAC with mol. weights of 2.25 × 103, 2.18 × 103, and 1.92 × 103 kDa, resp., were composed of rhamnose, xylose, mannose, arabinose, glucose, and galactose. Functional properties (solubility, oil holding capacity, foaming, and emulsion properties) of these polysaccharides were evaluated. Among three, PAL showed the highest fat-binding capacity which was 7.50 g/g with the solubility of 95.06%. The three polysaccharides possessed appreciable in vitro anti-oxidant (scavenging DPPH and ABTS+ radicals, chelating ferrous ions, and reducing power) potential. PAL exhibited the strongest reducing power, scavenging activity on DPPH radicals and chelating capability on ferrous ions. PP polysaccharides can be used as promising natural antioxidants in food, pharmaceutical, and cosmetic preparations

Herein, we isolated and purified polysaccharides from Craterellus cornucopioides. Chem. composition anal. revealed that both polysaccharides (CCPs-1 amd CCPs-2) were composed of different molar ratios of rhamnose, fucose, arabinose, xylose, mannose, glucose, and galactose. The structure of polysaccharides was determined using FT-IR, periodate oxidation, smith degradation, methylation anal., and NMR, which demonstrated that the two polysaccharides were primarily connected by mannose with (1â†?)-linked. Notably, the configuration of the two polysaccharides exhibited random coil with pyranoid polysaccharide containing α or β glycosidic bond. Furthermore, to increase the antioxidant activity of polysaccharides (CCPs-1 amd CCPs-2), two carboxymethylated polysaccharides were obtained as cmCCPs-1 and cmCCPs-2 with the degree of substitution values of 0.34 and 0.52, resp. Structural anal. elucidated that nonselective carboxymethylation occurred in cmCCPs-1 and cmCCPs-2, where C-2, C-4 or C-6 were partially substituted. Of note, cmCCPs-2 exhibited the most significant antioxidant activity.

Caser, Matteo published the artcileDrought stress adaptation modulates plant secondary metabolite production in Salvia dolomitica Codd, Recommanded Product: rel-(1R,2R,4R)-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-ol, the main research area is Salvia secondary metabolite drought stress adaptation.

Sage is an important medicinal and aromatic plant. While Salvia officinalis and S. miltiorrhiza have been widely studied, little information regarding S. dolomitica exists, although it has recently attracted attention due to its anti-plasmodial and anti-inflammatory properties. This study investigated the performance and metabolic profile of this species in response to two drought treatments (moderate or severe) relative to well-watered control plants. Changes in growth and ecophysiol. traits, as well as in bioactive and volatile compounds and essential oil production were determined Given that terpenoids are the most representative class of secondary metabolites, the gene expression of key enzymes of terpenoid biosynthesis was also investigated. Moderate drought stimulated a decline in leaf water potential, growth and stomatal conductance, as well as an increase in deyhdrin expression. Serious stress symptoms occurred only in severe drought-stressed plants, where a decline in net photosynthesis and transpiration and an increase in endogenous abscisic acid was observed Both drought stress conditions led to modulate the expression of some genes involved in biogenic volatile organic compound and essential oil biosynthesis and metabolic profile. In particular, drought induced an increase in sesquiterpene production, a class of terpenoids that is important in the food, cosmetics, and pharmaceutical industries. Thus, controlled drought, in addition to water savings during cultivation, can be applied to improve the production of secondary metabolites in S. dolomitica.

Zeng, Fanke published the artcileStructural characterization of polysaccharides with potential antioxidant and immunomodulatory activities from chinese water chestnut peels, Category: alcohols-buliding-blocks, the main research area is Eleocharis polysaccharide antioxidant immunomodulation; Antioxidant activity; Chinese water chestnut peels; Immunomodulatory activity; Polysaccharides; Structural features.

Chinese water chestnut peels are a kind of vegetable processing waste containing many active components such as polysaccharides, the structure of which remains unknown. To elucidate the structure of polysaccharides from Chinese water chestnut peels, two polysaccharides named WVP-1 and WVP-2 were isolated. WVP-1 (3.16 kDa) consisted of mannose (1.75%), glucose (84.69%), galactose (6.32%), and arabinose (7.24%), while WVP-2 (56.97 kDa) was composed of mannose (3.18%), rhamnose (1.52%), glucuronic acid (1.42%), galacturonic acid (4.83%), glucose (11.51%), galactose (36.02%), and arabinose (41.53%). Linkage and NMR data indicated that WVP-1 was composed mainly of â†?)-α-D-Glcp(1â†?and a certain proportion of â†?)-β-D-Glcp-(1â†? including linear and branched polysaccharides simultaneously. WVP-2 was a pectin-like polysaccharide with â†?)-α-D-GalpA6Me-(1â†?units and the branch points of â†?,4)-α-L-Arap-(1â†? â†?,6)-β-D-Galp-(1â†? WVP-2 exhibited stronger potential antioxidant and immunomodulatory activities than WVP-1 in vitro. These results provide a foundation for the further study of polysaccharides from Chinese water chestnut peels.
