(PROBLEMS) To provide a highly safe dietetic composition originating in green coffee beans by which excellent dietetic effects can be obtained and which contributes to the prevention and treatment of life style-related diseases such as diabetes. (MEANS FOR SOLVING PROBLEMS) A dietetic composition characterized by comprising, as the active ingredient, a polar solvent extract of defatted green coffee beans. It is preferable that the above-described polar solvent extract is an extract obtained by using water-containing ethanol, still preferably water-containing ethanol having an ethanol concentration of from 40 to 90% (wt/wt). It is preferable that the above-described defatted green coffee beans are those obtained by extracting green coffee beans with N-hexane to thereby separate oily components therefrom. It is recommended to combine the above-described dietetic composition with one or more members selected from amongextract, evening primrose extract, sesamine and. This dietetic composition is usable as a material for foods, drinks, drugs, or skin preparations for external use.

Method for promoting carnitine palmitoyltransferase activity using green coffee bean extract

This invention provides carbohydrate absorption inhibitor derived from evening primrose seed which is significantly effective to prevent and cure diabetes mellitus and prevent obesity, and the manufacturing method of the same. Carbohydrate absorption inhibitor in this invention is characterized that the effective component is an alcohol extract of evening primrose seed. The aforementioned evening primrose seed is preferably a defatted evening primrose seed. Extracting solvent of the aforementioned evening primrose seed is preferably ethanol, or preferably a 70 to 85% (v/v) aqueous ethanol. Also, this invention is characterized that the carbohydrate absorption inhibitor is an effective component of polyphenol derived from evening primrose seed. The polyphenol is preferably one or more substances selected from among gallic acid, ellagic acid, catechin, pentagalloylglucose, procyanidin, and proantocyanidin. The manufacturing method of the carbohydrate absorption inhibitor in this invention is characterized to be composed of the following processes A to C. Process A: evening primrose is compressed, oil is separated then the compressed cake is obtained. Process B: The aforementioned compressed cake is defatted in fat-soluble organic solvent, and defatted substance is obtained. Process C: The aforementioned defatted substance is extracted by alcohol, and then this extracted liquid is concentrated or evaporated.
