<P>PROBLEM TO BE SOLVED: To provide a safe immunostimulator which can be used as a pharmaceutical or a food material, to provide a method for producing the same, and to provide a new method for using a coffee extract residue. <P>SOLUTION: The immunostimulator contains a coffee extract as an active ingredient. Preferably, the coffee extract is an extract containing arabinogalactan. The immunostimulating activity is originated from the promotion of the proliferation of an immunocompetent cell such as a macrophage. The immunocompetent cell is preferably one selected from a macrophage like strain RAW264, a murine splenocyte, and a murine peritoneal macrophage. A composition containing the immunostimulator can be used as a composition such as a pharmaceutical composition, a food composition or a cosmetic composition. <P>COPYRIGHT: (C)2009,JPO&INPIT |
