A water soluble polysaccharide, HB-1, with a molecular weight of 23,930, was isolated from radix Ranunculi ternati. by hot water extraction, ethanol precipitation, deproteination，ultrafiltration and gel-filtration column chromatography. Its sugar composition was determined by GLC as Glc, Ara, and Gal in a molar ration of 16.071: 2.722: 1. And the absolute configuration of Glc was identified as ...

Introduction A very important aspect of food quality is related to the nutritional quality and the effect on consumers’ health. As a result of processing, many foods are deprived of some substances having great importance for health, among which is the dietary fibre (DF). DF has some beneficial physiological effects, such as improving the bulk motility, decreasing blood cholesterol and glucose,...

Xanthan gum is a water-soluble polysaccharide obtained by fermentation of the genus Xanthomonas with several properties, such as low-cost, biodegradability, biocompatibility and non-toxicity. However, an important limitation xanthan gum-based biomaterials high swelling degree in solvent mechanical weakness, which results biomaterial disintegration. For this reason, aim work was to develop hydro...

1. The cell wall of Clostridium welchii (type A) contains alanine, 2,6-diaminopimelic acid, glutamic acid, glycine, glucosamine, muramic acid, galactosamine, mannosamine, ethanolamine, rhamnose, galactose and phosphorus. 2. Heating with formamide at 150 degrees resolved the wall into a formamide-soluble polysaccharide fraction and a formamide-insoluble mucopeptide fraction. 3. The formamide-sol...

our previous study revealed that the antioxidant activity of polysaccharide (coded as fgfp) extracted from grifola frondosa by enzymolysis treatment was significantly superior than that (coded as gfp) extracted by boiling-water. in this study, one purified polysaccharide fractions (coded as fgfp-11) was obtained from fgfp by purified using deae-52 column and sephacryl s-500hr column. results in...

purpose of this study was to investigate the effect of the presence of the water soluble polymers viz hpmc, pvp and peg 6000 on aqueous solubility and complexation abilities of felodipine with or without presence of β-cyclodextrin (βcd) and hpβcd by phase solubility studies. the data revealed the initial increase in drug solubility followed by plateau in the presence of relatively low polymer c...

The polysaccharides of Astragalus membranaceus have received extensive study and attention, but there have been few reports on the extraction of these polysaccharides using cold water (4 °C). In this study, we fractionated a novel cold-water-soluble polysaccharide (cAMPs-1A) from Astragalus membranaceus with a 92.00% carbohydrate content using a DEAE-cellulose 52 anion exchange column and a Sep...

BACKGROUND Viscous soluble dietary fiber has been demonstrated to reduce postprandial glycemia and may promote satiety. PolyGlycopleX (PGX) is a highly viscous polysaccharide manufactured by reacting glucomannan with other soluble polysaccharides using a proprietary process (EnviroSimplex). The resulting polysaccharide (alpha-D-glucurono-alpha-D-manno-beta-D-manno-beta-D-glucan, alpha-L-guluron...

S.typhimurium is a gram negative bacterium causing serious enteric or extraintestinal infections in human, cattle and birds. These kinds of infections may lead to some permanent or nonpermanent complications like endophthalmitis, Guillain-Barre syndrome and osteomyelitis . Multi-resistant strains of S.typhimurium have been reported from several countries, and these infections are a major public...

Diabetes mellitus (DM) is a metabolic syndrome caused by multiple genetic and environmental factors. Traditional Chinese medicine preparations have shown a comprehensive and function-regulating characteristic. Purslane (Portulaca oleracea L.) is an annual succulent herb. Currently, there have been some related reports on the treatment of diabetes with purslane. The current study was designed to...
