To obtain monosaccharide components information of Dendrobium moniliforme polysaccharides, a HPLC-ESI-MS method was proposed. The crude polysaccharides were extracted and purified from D. moniliforme as samples (DMP). Then, the polysaccharides were hydrolyzed with trifluoroacetic acid (TFA) and derivated by 1-phenyl-3-methyl-5-pyrazolone (PMP). PMP-labeled mixture of monosaccharides were separa...

Grape variety has a significant impact on wine flavan-3-ol and polysaccharide profile. The main objective of this work was to study differences in diffusion from grape during the fermentative alcoholic maceration three Vitis sp. varieties: cold-hardy hybrid varieties Frontenac blanc, V. vinifera Cabernet-Sauvignon. Polysaccharides must were precipitated by ethanol quantified using phenol-sulfur...

The combined fouling during ultrafiltration (UF) of surface water pretreated to different extents was investigated to disclose the roles of polysaccharides, proteins, and inorganic particles in UF membrane fouling. Both reversible and irreversible fouling decreased with enhanced pretreatment (biologically active carbon (BAC) treatment and sand filtration). The sand filter effluent fouled the me...

The 23-valent pneumococcal polysaccharide vaccine was formulated to prevent invasive infection in the elderly and other high-risk populations from the most prevalent Streptococcus pneumoniae serotypes. However, the immunogenicity of all 23 vaccine polysaccharides has not been fully characterized in elderly adults. We previously reported that whereas the majority of elderly subjects had vigorous...

Article history: Received on: 28/01/2014 Revised on: 17/02/2014 Accepted on: 09/03/2014 Available online: 28/07/2014 Polysaccharides from mushroom Pleurotus sajor-caju (PS1) and Lactuca Sativa (PS2) were isolated and purified (22.40 and 26.80g/100g respectively). Cytotoxic activities of PS1 and PS2 were examined In vitro using colon (HCT 116), liver (HEPG2), cervical (HELA) and breast (MCF7) ca...

Because of certain undesirable reactions, such as elevation in temperature and drop in blood pressure, observed in patients receiving tumor-necrotizing polysacchatides, it is important to investigate procedures which have potentialities for reducing the toxicity of the polysaccharides without interfeting with the tumor-necrotizing action. I t seemed advisable, therefore, to ascertain whether pa...

For several decades attention has been directed to natural polysaccharide gels and synthesized polymer gels. The structure-function relationships at molecular level in water of polysaccharides, κ-carrageenan, ι-carrageenan, agarose (agar), and gellan family of polysaccharides (gellan, welan, rhamsan, S-657, deacetylated rhamsan and native gellan gum), which are industrially useful polysaccharid...

BACKGROUND Seaweeds or marine algae have long been made up a key part of the Asian diet, and as an antioxidant, sulphated polysaccharides have piqued the interest of many researchers as one of the ocean's greatest treasures. The present investigation suggests the therapeutic potential of sulphated polysaccharides from marine brown algae "Sargassum wightii" in Cyclosporine A (CsA)- induced liver...

The gut microflora dysbiosis has been closely related with the inflammatory bowel disease (IBD). In this study, the effect of polysaccharides from Chrysanthemum morifolium Ramat on the gut microbiota was evaluated by ulcerative colitis (UC) rat model. Physiological and pathological analyses suggested that Chrysanthemum polysaccharides possessed notably protective effects on UC in vivo. Based on...

Plant cell wall (CW) polysaccharides are responsible for the mechanical strength and growth of plant cells; however, the high-resolution structure and dynamics of the CW polysaccharides are still poorly understood because of the insoluble nature of these molecules. Here, we use 2D and 3D magic-angle-spinning (MAS) solid-state NMR (SSNMR) to investigate the structural role of pectins in the plan...
