Abstract
The invention comprises a bismuth complex of a polysaccharide, and salts and derivatives thereof. Specified polysaccharide moieties are cellulose, starch, pectins, and derivatives thereof, araban, gum tragacanth, gum acacia, agar, carrageenin, linseed mucilage and extract of liquorice. The preferred complex is sodium polybismuthyl-demethoxy pectinate. This is made by reaction of bismuth nitrate with saccharose (sucrose) to form bismuthyl saccharose, followed by double decomposition of this with demethoxylated pectin. The product containing complexed Bi(OH)3 molecules, forms a colloidal suspension in water. It is solubilised by lower polyols in alkalene medium, and reacts with thiourea, cysteine and thioglycolic acid. Polybismuthyl nitro-demethoxy pectinate is also specified. The complexes inhibit the proteolytic action of pepsin.
