Book Description :

Polysaccharides are abundant in Chinese medicines (CMs) and play important roles in these materials’ bioactivities. But at present, the polysaccharides are seldom incorporated into the quality assessment system of CMs. One of the big bottlenecks encountered is the difficulties in quality analysis due to their large molecular mass, diverse and complex chemical structure. Hereby, in current study, evidence and improved analysis approaches related to polysaccharides quality are proposed by employing several CMs as objectives. Firstly, Lingzhi (Ganoderma lucidum and G. sinense) was used to provide evidence of the importance of polysaccharides quality assessment in CMs. The results showed that the polysaccharides from two species shared the same structural features in terms of mono-/oligo-saccharide profiles, molecular size, sugar linkages, and IR/NMR spectra. And these polysaccharides showed no obvious difference in antitumor/immunomodulating activities and mechanism related to the activation of some proteins via TLR-4 related signaling pathway and gut-microbiota modulatory effects. Following that, to solve the problems existed in qualitative and quantitative analysis of polysaccharide in CMs, a fluorescence-labeled oligosaccharide-marker approach was raised accordingly based on LC-DAD-qTOF -MS analysis. Taking Danggui Buxue Tang (DBT) as an example, the result showed that 1) selected oligosaccharide marker generated by mild hydrolyzation and ABEE-labeling could powerfully differentiate individual herb polysaccharides. 2) good linearity was established between the identified oligosaccharide-markers and individual polysaccharides (r≥0.99). 3) the established method had satisfactory repeatability (RSD≤8.4%), recovery (≥80%) and sensitivity in polysaccharide quantitation in DBT. Finally, a polysaccharide quality analysis was conducted to dynamically trace the absorption, dynamic distribution and degradation of orally-dosed DOP (a marker polysaccharide from Dendrobium officinale) in mice and in vitro using near-infrared fluorescence imaging and chromatographic analysis. The results indicate that DOP was not absorbed and digested but were quickly degraded to short-chain fatty acids in the large intestine where gut microbiota existed. The interaction could be associated with DOP’s suppression of 4T1 tumor growth in mice. In conclusion, by these studies, the importance of bioactive polysaccharides in quality assessment of CMs was confirmed. The mentioned predicaments in quality analysis of polysaccharides were greatly improved whether in CMs or complex biological matrix in vivo and in vitro. All the approaches proposed will contribute to other polysaccharides or polysaccharide-dominated CMs’ analysis.

Book Description :

This authoritative reference work presents comprehensive information about one of the most important and most wide-spread classes of (bio)organic compounds: the polysaccharides. The comprehensive and thoroughly up-to-date handbook presents the sources, identification, analysis, biosynthesis, biotechnology and applications of important polysaccharides likes starches, cellulose, chitin, gum and microbial polysaccharides. Polysaccharides can exhibit complex structure and various functional activities. These bio macromolecules can therefore serve as raw materials for various different materials, e.g. rayon, cellulose acetate, celluloid and nitrocellulose; and they find multiple applications, for instance as surgical threads (chitin), as sources of energy, dietary fibers, as blood flow adjuvants, in cosmetics, emulsion stabilizers, film formers, binders, viscosity increasing agents or skin conditioning agenta, as food additives in gums, chewing gum bases and as vaccines. Polysaccharides form the basis for useful products, like xanthan gum, dextran, welan gum, gellan gum, diutan gum and pullulan. Some of the polysaccharide-derived products have interesting and useful properties and show biological activities, such as immunomodulatory, antibacterial, anti-mutagenic, radioprotective, anti-oxidative, anti-ulcer, antidepressant, anti-septicaemic or anti-inflammatory activities. All these applications and properties of polysaccharides are for the first time compiled in a thorough and comprehensive overview in the present work. This reference work is organized thematically in four parts: Part I. Polysaccharides: Occurrence, Structure, Distribution and Biotechnology. Part II. Methods. Part III. Bioactive Polysaccharides. Part IV. Polysaccharides as Food. This reference work is edited by experienced experts, all chapters are written by well recognized international specialists. It is useful to all those working in the field of botany, phytochemistry, pharmacy, drug delivery, molecular biology, metabolomics, forestry, environment, conservation, biotechnology and NGOs working for forest protection.

Book Description :

This book covers the functionalisation of silicone surfaces with polysaccharides to improve their antimicrobial and antifouling properties, thus reducing the implant-related infections. The authors describe how silicone surfaces were chosen because silicone exhibits excellent biocompatible properties and is already being used for medical implants such as catheters, breast implants, prosthetics etc. The potential of polysaccharides such as cellulose, chitosan, hyaluronic acid, and other natural substances such as natural surfactants as coatings for silicones are also discussed, their effects are evaluated. With the aging of the population, the number of medical implants is growing and with it the number of infections associated with the use of implants.

Book Description :

The complex world of polysaccharides is a compilation of the characteristics of a variety of polysaccharides from plants, animals and microorganisms. The diversity of these polysaccharides arises from the structural variations and the monosaccharide content which is under genetic control. The chemical and physical properties have made them useful in many pharmaceutical, food and industrial applications. These properties of the polysaccharides determine their biological activity and their function in various applications. The role played by polysaccharides in preservation and protection of food, as carriers of nutrients and drugs, their ability to interact with molecules both for efficient delivery as well as improving textures of food colloids and their use as therapeutics are some of the functions discussed.
