Abstract
(EN)
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.

L'invention concerne un procédé servant à isoler des polysaccharides mucilagineux depuis des plantes, des céréales, des cultures de cellules ou des champignons connus pour leur teneur en polysaccharides mucilagineux ou fixés à des protéines, qui possèdent des propriétés biologiques appréciables. On traite les polysacharrides mucilagineux présents dans une solution aqueuse ou des extraits de tissus avec des tanins afin d'obtenir un complexe qu'on sépare ensuite de la solution. On traite ce complexe une ou plusieurs fois soit avec des solvants, soit avec d'autres substances en solution, de manière à supprimer les tanins liés du complexe et à dégager le polysaccharide isolé. Les polysaccharides préparés au moyen de ce procédé possèdent des propriétés pratiquement semblables à celles du polysaccharide natif tel qu'on le trouve dans la plante ou la cellule respectives. On utilise les polysaccharides préparés de cette façon dans une variété de produits. Ce procédé s'applique particulièrement pour isoler des polymères de mannose acétylés de plantes d'aloès et de bêta-glucanes.
