Abstract: Provided is an anti-aging agent for skin which contains, as an active component, an inositol derivative in which a monosaccharide or an oligosaccharide is bonded to inositol, in which a total amount of the monosaccharide or the oligosaccharide bonded to one inositol molecule is 2 or greater in terms of monosaccharide unit.

Abstract: A plant biomass; a solid catalyst which can catalyze the hydrolysis of the biomass; and a method for hydrolyzing a plant biomass, which is characterized by a step of heating a mixture containing an inorganic acid and water and which has high glucose yield and high glucose selectivity. As the inorganic acid, hydrochloric acid can be used. The pH value is adjusted to 1.0 to 4.0. As the solid catalyst, activated carbon or the like can be used.

Abstract: A method for producing an inositol derivative includes a step of reacting inositol and dextrin in the presence of cyclodextrin glucanotransferase to generate an inositol derivative in which a sugar is bonded to the inositol, and to obtain a solution containing the inositol derivative and the cyclodextrin glucanotransferase; and a step of removing the cyclodextrin glucanotransferase in the solution using an ultrafiltration membrane, in which a deactivation treatment of the cyclodextrin glucanotransferase in the solution is not performed.
