Ganoderma lucidum is commonly used in Vietnam and other countries since more than 4000 years ago with excellent beneficial health effects Lingzhi has potential applications as a functional product with polysaccharide, and many other healthy components. This polysaccharide obtained good application in human. Lingzhi becomes a common mushroom in Vietnam, growing almost all year. The fruit of this...

Dendrobium officinale is a traditional Chinese medicine and nourishing food in China. Polysaccharide content was used as criterion for evaluating the quality of D. officinale. At present, epiphytic cultivation main method In present study, collected under various growing conditions to compare its polysaccharide an attempt discover most favorable officinale, which can be guide artificial product...

Mucilage of Plantago ovata husk has various characteristics like binding, gelling, granulating, film former, disintegrating, suspending, and sustaining properties and could be utilized for the preparation of pharmaceutical dosage forms like tablets, suspensions, gel and for sustained drug release systems. The present paper deals with the spectrophotometric estimation of total polysaccharide con...

To find biocatalyst allowing depolymerization of new polysaccharides, one needs to get a sensitive and well adapted method to a screening program. This led us to compare biochemical methods of detection of the depolymerization. Currently used methods such as reducing sugars assays, double bond monitoring or molecular weight determination were tested to follow the kinetic of depolymerization wit...

1. A rapid method for the roughly quantitative estimation of mucoid polysaccharide in hemolytic streptococci has been described. 2. Using this method, about 94 per cent of strains from moderate or severe streptococcal infections in man have been found to produce mucoid polysaccharide in greater or less amount. In a group of streptococci from normal throats only about 8 per cent produced this su...

We discuss a simple modification of the well-known method of giant vesicle electroformation that allows for a direct addition of water-soluble species to the phospholipid bilayers. Using this modified method, we prepare phospholipid vesicles decorated with chitosan, a water-soluble polysaccharide currently investigated for potential pharmacological applications. We find that the method allows t...

The chemical structure of a polysaccharide from the broth of cultured Streptomyces virginia H03 was investigated. There might be 1-->2 and 1-->4 and no 1-->6 glycosidic linkages in the polysaccharide according to periodate oxidation and Smith degradation. Four fragments including 2,3,4,6-Me4-Man, 2,3,6-Me3-Gal, 2,4,6-Me3-Glc, and 3,6-Me2-Man were found in the methylated polysaccharide. Furtherm...

1. A method is given for the concentration and purification of the soluble specific substance of the pneumococcus. 2. The material obtained by this method is shown to consist mainly of a carbohydrate which appears to be a polysaccharide built up of glucose molecules. 3. Whether the soluble specific substance is actually the polysaccharide, or occurs merely associated with it, is still undecided...

Dendrobium officinale is one of the most well-known traditional Chinese medicines, and polysaccharide is its main active ingredient. Many studies have investigated the synthesis and accumulation mechanisms of polysaccharide, but until recently, little was known about the molecular mechanism of how polysaccharide is synthesized because no related genes have been cloned. In this study, we cloned ...

AIM To investigate the fate of Streptococcus pneumoniae C-polysaccharide antigen in serum in patients with S pneumoniae bacteraemia. METHOD In vitro dissociation experiments were performed to demonstrate that C-polysaccharide was masked by ligands in normal and acute phase serum. Serum samples from 22 patients with S pneumoniae bacteraemia were treated to dissociate immune complexes and then ...
