Description
[1]タキシフォリンを含有するヒト用機能性組成物であって、認知機能改善のためのものである該ヒト用機能性組成物。
[2]50歳以上の健常者を対象とするものである、上記[1]記載のヒト用機能性組成物。
[3]軽度認知障害の者を対象とするものである、上記[1]記載のヒト用機能性組成物。
[4]前記タキシフォリンを1日当たり50mg~150mgを4週間以上にわたって摂取するためのものである、上記[1]記載のヒト用機能性組成物。
(a)認知機能改善のためのものであるヒト用機能性組成物。
(a1)50歳以上の健常者を対象とするものである。
(a2)軽度認知障害の者を対象とする。
(a3)タキシフォリンを1日当たり50mg~150mgを4週間以上にわたって摂取するためのものである。
タキシフォリンの摂取がヒトの認知機能にどのように影響を与えるか調べた。具体的には、認知機能検査ツールCognitrax(コグニトラックス)(提供:株式会社ヘルス・ソリューション、開発元:CNS Vital Signs社)を使用した検査を実施した。
物忘れの自覚がある、又は物忘れを指摘されたことがある55歳以上80歳未満の健常な日本人男女を対象にした。
タキシフォリンを90質量%含有するカラマツエキス末を、他の賦形素材とともに含むハードカプセルを被験食品とした。また、カラマツエキス末を含まないハードカプセルを対照食品とした。表1に、カプセル1粒あたりの各試験食品の組成を示す。
責任医師等の判断により試験への参加に問題がないとされた者、その60名を選定し、年齢、性別、並びに事前のコグニトラックス(Cognitrax)検査による算出値(標準化スコア)及び血中アミロイドβの測定値に基づき、これらを割付調整因子として偏りがないよう2群に割付けた。
試験群間の統計的有意差を、検査時における対照食品群と被験食品群の比較に基づく評価については、対応のないt検定により解析した。また、摂取前時から摂取6週時又は摂取12週時にわたる経時的な比較に基づく評価については、対応のあるt検定(Bonferroni法)により解析した。
図1に示されるように、被験食品の摂取群の摂取6週時及び摂取12週時において、対照食品の摂取群に比べて、画面に映し出された図形を認識して記憶する検査評価項目である「視覚記憶テスト」における「正解ヒット数(遅延)」の算出値の向上がみられた。
Claims (2)
- タキシフォリンを含有するヒト用機能性組成物であって、55歳以上の健常者を対象とし、視覚的記憶力にかかわる認知機能改善のためのものである、該ヒト用機能性組成物。
- 前記タキシフォリンを1日当たり50mg~150mgを4週間以上にわたって摂取するためのものである、請求項1記載のヒト用機能性組成物。
