Paragraph 0041, (2016/12/01)
PROBLEM TO BE SOLVED: To provide a method for obtaining alkyl N-acetylglucosaminide that comprises few content of N-acetyl glucosamine as impurities, conveniently and efficiently with a low cost. SOLUTION: The invention provides a production method of alkyl N-acetylglucosaminide comprising a step of reducing the content of N-acetyl glucosamine by contacting a mixture of alkyl N-acetylglucosaminide and N-acetyl glucosamine with strongly basic anion exchange resin (where, alkyl means an alkyl group of carbon number 1-4). The invention relates to the production method of alkyl N-acetylglucosaminide which is a mixture of alkyl N-acetylglucosaminide and N-acetyl glucosamine obtained by reaction of N-acetyl glucosamine, chitin, or chitin oligosaccharide with alkyl alcohol under the presence of an acid, or transglycosidation of chitin or chitin oligosaccharide using an enzyme with N-acetylhexosaminidase activity in a mixed solution of alkyl alcohol and water.

Page/Page column 5, (2011/08/04)
The present invention herein provides a proliferation inhibitor of H. pylori bacteria comprising a compound that can specifically inhibit the proliferation of H. pylori bacteria, which does not generate bacterium resistant, can be eaten, drunken or administrated safely for a long period of time, can be simply mass-manufactured and can be used for foods and beverages or pharmaceutical preparation. The proliferation inhibitor of H. pylori bacteria comprises an N-acetylglucosaminyl beta-linked monosaccharide derivative represented by the following chemical formula (1): ????????GlcNAc1-beta-O-Y?????(1) wherein Y is an alkyl group, an alkoxyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, a heteroaryl group, a carboxyl group or an alkoxycarbonyl group.
