PROBLEM TO BE SOLVED: To provide means which can efficiently extract a water-soluble active ingredient from an artichoke and also efficiently extract a linoleic acid derivative, being a lipophilicity component.SOLUTION: When artichoke extract is produced from artichoke, an artichoke is treated with a plant tissue collapse enzyme and then water with pH 7 to 12 is used as an extracting solvent to extract at 40-121°C.COPYRIGHT: (C)2015,JPO&INPIT【課題】アーティチョークから水溶性の有効成分を効率よく抽出しつつ、脂溶性成分であるリノール酸誘導体をも効率よく抽出しうる手段を提供する。【解決手段】アーティチョークよりアーティチョーク由来抽出物を製造する際、アーティチョークを植物組織崩壊酵素で処理した後に、pH7~12の水を抽出溶媒として用いて40~121℃にて抽出を行う。【選択図】なし
