Provided are a piceatannol-containing composition which is a composition originating in a natural material and containing piceatannol at a high concentration, and a method of producing the piceatannol-containing composition. A piceatannol-containing composition which contains 0.0001 to 99.9% by mass of piceatannol is obtained by extracting passion fruit seeds. The extraction of piceatannol is carried out by grinding the passion fruit seeds, adding at least one solvent selected from an aqueous alcohol-based solvent and an aqueous ketone-based solvent and agitating to thereby extract piceatannol into the above-described solvent. In this case, it is preferable to conduct stepwise extraction by using both of the aqueous alcohol-based solvent and the aqueous ketone-based solvent.

A composition for lowering internal lipid in a subject which contains a capsinoid substance represented by the following formula wherein n is an integer from 0 to 10. Methods of using the compositions are disclosed and include administering to a subject in need of such treatment.

Composition for lowering internal lipid content

A method for reducing the blood ammonia concentration in a human comprising administering to a human in need thereof a pharmaceutically effective amount of a cocoa component.

Method for reducing blood ammonia concentration

A method for one-step immunoassay of human type IV collagen, which uses a carrier immobilizing monoclonal antibody against human type IV collagen and a labelled polyclonal antibody against human type IV collagen, as well as a kit therefor and monoclonal antibodies which are particularly suited therefor. It is possible to accurately and quickly measure human type IV collagen in blood serum, for example, and obtain measurement results which accurately reflect pathological conditions.
