Zusammenfassung:	To provide a composition and a method for producing the same that solves the problem of poor water solubility, which is a problem when a konjac root extract is used as a raw material for cosmetics, a health food material or a pharmaceutical material.SOLUTION: A water-soluble konjac root extract has a fatty acid ester content of 1,000 mg/100 g or less and a plant sterol content of 5,000 mg/100 g or less. A method for producing the same includes an extraction step of extracting konjac root extract from konjac root powder using organic solvent, and a separation step of separating fatty acid ester and plant sterol from the konjac root extract by column chromatography so that the contained amount of fatty acid ester is 1,000 mg/100 g or less and the contained amount of plant sterol is 5,000 mg/100 g or less.SELECTED DRAWING: Figure 1 【課題】こんにゃく芋抽出物を化粧品原料や健康食品素材もしくは医薬品素材として使用する場合に問題となる難水溶性を解決した組成物及びその製造方法を提供する。【解決手段】脂肪酸エステルの含有量が１，０００ｍｇ／１００ｇ以下であり、植物ステロールの含有量が５，０００ｍｇ／１００ｇ以下である水溶性こんにゃく芋抽出物とする。その製造方法は、有機溶剤を用いてこんにゃく芋の粉からこんにゃく芋抽出物を抽出する抽出工程、およびカラムクロマトグラフィーにより、こんにゃく芋抽出物から脂肪酸エステルおよび植物ステロールを分離することにより、脂肪酸エステルの含有量を１，０００ｍｇ／１００ｇ以下、かつ、植物ステロールの含有量を５，０００ｍｇ／１００ｇ以下とする分離工程を含む。【選択図】図１
