PROBLEM TO BE SOLVED: To provide a method for obtaining the composition of chlorogenic acids containing the chlorogenic acids in high concentrations and reduced with caffein, in a high yield.SOLUTION: This method for producing the composition of the chlorogenic acids is provided by making water soluble composition extracted from raw coffee beans or roasted coffee beans adsorbed on a column filled with an adsorbent, and then eluted by passing the liquid of 0.5-20 vol % aqueous ethanol solution.COPYRIGHT: (C)2006,JPO&NCIPI【課題】 クロロゲン酸類を高濃度で含有し、カフェインを低減させたクロロゲン酸類組成物を高収率で得る方法の提供。【解決手段】 生コーヒー豆又は焙煎コーヒー豆から抽出した水溶性組成物を、吸着剤が充填されたカラムに吸着させ、次いで0.5~20vol%のエタノール水溶液を通液して溶出させることを特徴とするクロロゲン酸類組成物の製造方法。【選択図】 なし
