摘要： This invention relates to a process for readily and efficiently preparing L-rhamnose with the use of a marine alga belonging to the family Monostromaceae, Ulvales.According to the process of the present invention, rhamnan sulfate is extracted from a marine alga belonging to the family Monostromaceae such as Monostroma nitidium Wittrock and the obtained extract is hydrolyzed by adding acid(s) thereto followed by heating or treating thereof with a cation exchange resin followed by heating to thereby give a solution containing free L-rhamnose.Since the solution thus obtained contains a large amount of salts, the removal of these salts is significantly important in the preparation of L-rhamnose. In the present invention, an effective process therefor is combined with a conventional method by using an ion exchange resin to thereby establish an efficient desalting process.Further it is effective to elevate the purity of L-rhamnose by adding baker's yeast, which selectively ferments various sugars, to the solution containing L-rhamnose.

摘要： A D-glucose solution is added molybdic acid compound thereto and heated at a temperature of 110.degree.-160.degree. C with pH 2.0-4.5 to perform epimerizing reaction of D-glucose, and thereby 30-36%, based on the D-glucose, of D-mannose is formed. To the epimerized mixture thus obtained is further added glucose-isomerase to perform enzymatic isomerizing reaction of D-glucose remaining in the epimerized mixture, thereby 46% based on the remaining D-glucose is converted into D-fructose. The epimerized mixture or enzymatically isomerized mixture is subjected to catalytic hydrogenation under high pressure, and thereby is produced D-mannitol at high yield based on the initial D-glucose.
