  • Patent number: 6770756
    Abstract: It is the object of the present invention to provide an industrially useful process for the manufacture of polyguluronic acids having degrees of polymerization less than 20 and substantially free of mannuronic acid contamination. Alginate salts of organic bases are quite soluble in aqueous solution, and remain soluble in aqueous solution throughout a hydrolysis reaction in the range of pH values at which the acidic hydrolysis is effected at a reasonably fast rate. Based on this finding, a solution containing 5 wt. % or more of alginic acid prepared by dissolving alginic acid in water by neutralization with an organic base is provided and then hydrolyzed under acidic conditions, followed by selective precipitation of polyguluronic acids under acidic conditions.

    Abstract: An entirely aqueous method for concentrating water soluble polysaccharides having molecular weights of at least about 50 kDa. The method comprises evaporating a water soluble polysaccharide-containing solution until surface film formation occurs, and harvesting the resulting film which is enriched in the polysaccharide. The polysaccharide may be of plant or animal origin, and includes polysaccharides such as guar gum, xanthan gum and pectin.

  • Patent number: 6482942
    Abstract: The present invention provides a method of isolating mucilaginous polysaccharides from plants, cereals, cell cultures, or fungi such as mushrooms known to have mucilaginous or protein-bound polysaccharides with desirable biological properties. The mucilaginous polysaccharides present in aqueous solution or tissue extracts are treated with tannins to form a complex which is then separated from the solution. The complex is then treated one or more times with either solvents or other substances in solution to remove the bounded tannins from the complex thereby and releasing the isolated polysaccharide. The polysaccharides prepared according to the present method retain properties that are substantially similar to those of the native polysaccharide as it is found in the respective plant or cell. The polysaccharides thus prepared are used in a variety of products. This process is particularly suitable for isolating acetylated mannose polymers from aloe plants and beta glucans.

  • Patent number: 6465203
    Abstract: The present invention provides methods of making paper, utilizing glucans, produced by the glucosyltransferase B, C or D enzyme of the species Streptococcus mutans, instead of modified starches. The present glucans are functionally similar to currently utilized modified starches and are particularly useful in the coating step of paper manufacture. The present glucans also exhibit thermoplastic properties and impart gloss to the paper during the coating step.

  • Patent number: 6444654
    Abstract: The isolation and purification of lipopolysaccharides from several related strains of eukaryotic algae is disclosed. These lipopolysaccharides have been shown to be structurally and functionally similar to the lipopolysaccharides of gram negative bacteria, or endotoxins, which have been shown to be a cause of sepsis or septic shock. The present invention also relates to the use of these algal lipopolysaccharides to inhibit the release of TNF-a from macrophages, which has been associated with the initiation and escalation of sepsis as a result of bacterial endotoxins. The present invention further relates to the use of these algal lipopolysaccharides to inhibit the innate immune system of insects and mammals.

  • Patent number: 6436679
    Abstract: The present invention provides a rapid and efficient method for the preparation and isolation of biologically active polysaccharides from Aloe. The present invention includes the activated mixture of polysaccharides (referred to herein as “Immuno-10”), produced by the methods of the invention. The invention also includes the use of the polysaccharides as immunostimulating, immunomodulating and wound healing agents. The resulting imrnunomodulatory complex has a higher activity and is more stable than bulk carbohydrates isolated using prior art alcohol precipitation schemes.

  • Patent number: 6417349
    Abstract: A water-soluble extract of asiaticoside and madecassoside from Centella asiatica and an isolating method thereof. In the isolating method an aqueous alcohol containing Centella asiatica is subjected to cold-precipitation to obtain an extract. The extract in the aqueous alcohol is treated with a halogenide solvent for layer separation, and then the aqueous layer is extracted with a higher alcohol. The extract in the alcohol layer is washed first with sodium hydroxide and then with water. After being concentrated, the extract is crystallized with ethyl acetate to obtain crystals and the crystals are washed. A method for treating liver cells in a mammal includes administering to a mammal an effective amount of the extract from Centella asiatica containing asiaticoside and madecassoside.
