| titleOfInvention | The sodium salt of carboxymethyl-beta- (1-3) -D-glucan-chitosan and a process for its preparation and use |
| abstract | The solution relates to the sodium salt of carboxymethyl-P- (1-3) -D-glucan-chitosan,nwhich is to be prepared, ie myceliumnAspergillus niger is subjected to alkaline hydroxide hydrolysisnmetal at 80 to 100 ° C for 0.5 to 2 hnand the polysaccharide obtained is activated e.g. concentratednalkali metal hydroxide at temperaturen40 to 70 ° C for 1 to 3 h or by ultrasonication atnaqueous polysaccharide suspension. Activated polysacchariden% is resuspended in 10 to 25 wt. hydroxide solutionnalkali metal, sodium chloroacetate is added in an amount ofncorresponding to 1 to 2 times the amount of activatednpolysaccharide and the mixture is left for 2-4 h at room temperaturentemperature. The mixture is then neutralized with inorganic acid,nthe low molecular weight fraction is removed e.g. dialysisnand the sodium salt of carboxymethyl-P- (1- [3] -D-glucan chitosan) is obtainednit is dried e.g. lyophilization. The compound is usednas a means of inhibiting pathogenic adherencenmicroorganisms to mucosal epithelial cells. |
