Abstract: Provided is method of maintaining or improving a skin barrier function in a subject comprising orally administering to the subject a composition comprising an oil-soluble extract from red paprika, wherein the oil-soluble extract contains a hexane-soluble component.

Abstract: Provided is method of maintaining or improving a skin barrier function in a subject comprising orally administering to the subject a composition comprising an oil-soluble extract from red paprika, wherein the oil-soluble extract contains a hexane-soluble component.

Abstract: Provided is a novel agent containing a plant-derived component, which has an effect against the dullness of the skin and an effect against the deterioration of a skin barrier function. A skin dullness suppressing agent or a skin barrier function maintaining or improving agent, which contains an oil-soluble extract derived from red paprika. It is preferred that the skin dullness suppressing agent or the skin barrier function maintaining or improving agent has a dosage form of an oral preparation, and it is also preferred that the oil-soluble extract contains a hexane-soluble component.

Abstract: An object of the present invention is to provide an anti-skin aging agent that can prevent skin aging such as spots, dullness, wrinkles, sags, and skin roughness. It has been found that resveratrol 3-O-?-glucoside has remarkable anti-skin aging effects such as melanogenesis suppression, hyaluronidase inhibition, anti-oxidization, cell activation, sirtuin gene activation, matrix metalloproteinase suppression, and anti-inflammation, and thus, can be used as an anti-skin aging agent.

Abstract: A method for producing an amylose-containing rayon fiber, comprising the steps of: mixing an aqueous alkaline solution of amylose with viscose to obtain a mixed liquid, spinning the mixed liquid to obtain an amylose-containing rayon fiber, and bringing the amylose-containing rayon fiber into contact with iodine or polyiodide ions, thereby allowing an amylose in the amylose-containing rayon fiber to make a clathrate including the iodine or polyiodide ions, wherein the amylose is an enzymatically synthesized amylose having a weight average molecular weight of 3×104 or more and 2×105 or less. A method for collecting iodine from brackish water with high efficiency utilizing the amylase-containing rayon fibers.

Abstract: An object of the present invention is to provide a glucan containing at least one residue selected from an N-acetylglucosamine residue and a galactose residue, and a modified product. The branched glucan of the present invention is a branched glucan wherein the branched glucan has a plurality of non-reducing ends and at least one residue selected from an N-acetylglucosamine residue and a galactose residue is bound via an ?-1,4-bond to each of two or more non-reducing ends of the branched ?-1,4-glucan, but neither an N-acetylglucosamine residue nor a galactose residue is present at the position other than the non-reducing ends of the branched ?-1,4-glucan.
