Abstract: It is an object of the present invention to solve the above-mentioned problems by using an optical arrangement that is totally different from the conventional CD spectra measuring method, and to provide a method and device for measuring circular dichroism spectra, which can measure the CD spectrum in much shorter time even with the use of a small light source. The method for measuring circular dichroism spectra according to the present invention comprising the steps of irradiating a white light projected from a white light source to a sample without dispersing the light into a monochromatic light, dispersing the light output from the sample, detecting a light intensity of the dispersed light by a detector having a sensor consisting of a charge-coupled device, and then measuring a circular dichroism spectrum of the sample on the basis of a result of the detection by the detector (FIG. 1).

Abstract: To provide a composition for treatment and/or prevention of skin disorder, intensive research has been conducted. As a result, a mangosteen (Garcinia mangostana L.) pericarp extract has been found to have a reducing effect on the skin disorder. The present invention provides a composition for treatment and/or prevention of skin disorder, the composition including a mangosteen pericarp extract.

Abstract: To provide a prophylactic and/or therapeutic agent for atopic dermatitis with minimal concerns of adverse drug reactions and high safety, various researches were conducted. As a result, it was found that an extract extracted from a mangosteen (Garcinia mangostana L.) peel with a polar solvent prevented or healed atopic dermatitis. That is, the present invention provides a prophylactic and/or therapeutic agent for atopic dermatitis comprising an extract extracted from a mangosteen peel with a polar solvent. Furthermore, the present invention provides a food containing the above-mentioned prophylactic and/or therapeutic agent for atopic dermatitis.
