本発明の第2の態様は、1,2,3−トリ−O−ガロイル−β−D−グルコース、1,2,6−トリ−O−ガロイル−β−D−グルコース、1,2,3,6−テトラ−O−ガロイル−β−D−グルコース、1,2,4,6−テトラ−O−ガロイル−β−D−グルコース、及びテリマグランジンIIからなる群より選択される1又は複数の化合物を有効成分として含み、タンパク質と糖からの終末糖化産物の生成に関連する1又は複数の反応を阻害する活性及び終末糖化産物の前駆物質を分解する活性を有することを特徴とする終末糖化産物前駆体分解剤を提供することにより上記課題を解決するものである。
たもの、或いは、カプセル、錠剤等、食品又は健康食品に通常用いられる任意の形態をとることができる。配合される食品の種類に特に制限はなく、例えば、コーヒー、果汁、清涼飲料水、ビール、牛乳、味噌汁、スープ、紅茶、茶、栄養剤、シロップ、マーガリン、ジャム等の液状(流動状)食品、米飯、パン、じゃがいも製品、もち、飴、チョコレート、ふりかけ、ハム、ソーセージ、キャンディーなどの固形形状食品等の主食、副食、菓子類ならびに調味料に配合することも可能である。用途に応じて、粉末、顆粒、錠剤等の形に成形してもよい。また、必要に応じて、賦形剤、増量剤、結合剤、増粘剤、乳化剤、着色料、香料、食品添加物、調味料等と適宜混合してもよい。
実施例1:ワビシの果皮からの化合物の分離・同定
化合物の分離の手順の概略は図1に示すとおりである。ワビシ(Trapa japonica)の乾燥果皮を70%アセトン中でホモジナイズ(図1中、「Homogenized in 70% aq. acetone」)した後、フィルターろ過(図1中、「filtd.」)及び遠心分離を行った。得られたアセトン抽出画分をジエチルエーテル(図1中、「Et2O ext.」)、酢酸エチル(図1中、「AcOEt ext.」)、水飽和ブタノール(図1中、「n-BuOH ext.」)を用いてそれぞれ抽出を行った。次に、酢酸エチル抽出画分をHPLCカラム(Toyopearl HW−40(内径2.2cm×50cm))に供して成分の分離、精製を行った。溶出は、30%メタノール→40%メタノール→50%メタノール→60%メタノール→70%メタノール→100%メタノール→メタノール:アセトン:水(7:1:2)→メタノール:アセトン:水(7:2:1)→70%アセトンの条件で行った。30%メタノール溶出液から1,2,3−トリ−O−ガロイル−β−D−グルコース、1,2,6−トリ−O−ガロイル−β−D−グルコース、1,2,3,6−テトラ−O−ガロイル−β−D−グルコースが得られた。また、メタノール:アセトン:水(7:1:2)溶出液より、ルゴシンD、メタノール:アセトン:水(7:2:1)溶出液よりコルヌシインGが得られた。なお、単離した化合物はMSやNMR等を用いた物理化学的及び分光学的データについて、純正品あるいは既知化合物のものと比較し同定した。
化合物の分離の手順の概略は図2に示すとおりである。トウビシ(Trapa bispinosa)果皮の熱水抽出物を、エーテル、酢酸エチル、ブタノールを用いて抽出した。次に、得られた酢酸エチル画分をHPLCカラム(Toyopearl HW−40C)に供して成分の分離、精製を行った。40%メタノール溶出液より、2,6−ジ−O−ガロイル−β−D−グルコース、50%メタノール溶出液より、1,2,3−トリ−O−ガロイル−β−D−グルコース、1,2,6−トリ−O−ガロイル−β−D−グルコース、2,3,6−トリ−O−ガロイル−β−D−グルコース、60%メタノール溶出液より、1,2,3,6−テトラ−O−ガロイル−β−D−グルコース、70%メタノール溶出液より、1,2,4,6−テトラ−O−ガロイル−β−D−グルコース、テリマグランジンIIが得られた。エラグ酸については、酢酸エチルおよびブタノールエキスのHPLC分析の結果、標準品との比較分析により、その存在を確認した。なお、単離した化合物はMSやNMR等を用いた物理化学的及び分光学的データについて、純正品あるいは既知化合物のものと比較し同定した。
2,6−ジ−O−ガロイル−β−D−グルコース、1,2,3−トリ−O−ガロイル−β−D−グルコース、1,2,6−トリ−O−ガロイル−β−D−グルコース、2,3,6−トリ−O−ガロイル−β−D−グルコース、1,2,3,6−テトラ−O−ガロイル−β−D−グルコース、1,2,4,6−テトラ−O−ガロイル−β−D−グルコース、1,2,3,4,6−ペンタ−O−ガロイル−β−D−グルコース、ルゴシンD、コルヌシインG、テリマグランジンII及びエラグ酸並びに陽性対照として、糖化反応の中間体である3−デオキシグルコソンからの終末糖化産物の生成反応を阻害することが知られているアミノグアニジンを用い、ヒト血清アルブミンとグルコースからの終末糖化産物の生成抑制活性(抗糖化活性)の評価を行った。
