調製例1.オリーブ抽出物の調製
オリーブ果実のオイル搾りカス8 kgを、80℃の熱水32 Lで30分間ずつ2回抽出した。ナイロンメッシュ(日本理化学器械株式会社製、商品名:NRS-500)でろ過をした後、#131(φ330 mm)ろ紙2枚+200 gハイフロスーパーセル(ナカライテスク株式会社)を用いた吸引ろ過により搾りカスを除き、抽出液を得た。50%アセトンにて洗浄し水で平衡化したアンバーライトXAD7-HP樹脂(ローム・アンド・ハース・ジャパン(株))5 L(カラムサイズφ14×32 cm)に、この抽出液を全量負荷した。5 Lの水で洗浄後、20 Lの水、35 Lの15%エタノール水溶液、20 Lの60%エタノール水溶液で順次溶出した。15%溶出画分と60%溶出画分を各々減圧濃縮した後、凍結乾燥し、それぞれ37.2 gと66.0 gの分画物を得た。このうち、60%溶出画分から得られた分画物をオリーブ抽出物(アクテオシド含量9.1%)として後の動物実験に用いた。
調製例2.アクテオシドの調製
オリーブ果肉の抽出エキス末(インデナ社製のオレアセレクト(商標)(Batch No.10219))100 gをメチルエチルケトン1200 mlと蒸留水600 mlに溶かし、3 L容の分液漏斗でよく振って、有機層を回収した。水層にメチルエチルケトン1200 mlを加えよく振って、有機層を回収し、更に同様の操作を繰返した。計3回分の有機層を合併し、濃縮、凍結乾燥を行い、52.5 gの乾燥物を得た。
実施例1.DRAの製造-1
ナリンギナーゼ(Penicillium decumbens由来、300 units/g、シグマ社製)0.37 mgを0.1 M酢酸緩衝液( pH 4.0) 1.68 mlに懸濁し、0.22 mg /mlの酵素液を調製した(略称:1/10)。この1/10酵素液を、0.1 M酢酸緩衝液( pH 4.0)を用いて希釈し、3倍、10倍、30倍希釈の酵素液を調製した(それぞれの略称:1/30、1/100、1/300)。ねじ口ガラス試験管にそれぞれの酵素液を0.9 ml採取し、調製例2で得られた精製アクテオシドの50%エタノール水溶液(20 mg/ml)0.1 mlを添加し、40℃にて振とうした(100-130回/分、Water Bath Shaker MM-10型、大洋科学工業(株)(現在タイテック(株))製)。反応開始1、2、3、4、5、24時間後に0.1 ml採取し、除タンパクを目的にして、等量の氷冷したアセトニトリルを添加撹拌し、10分氷冷下に静置したのち、遠心分離をおこなった(10000回転、10分、5℃、微量高速冷却遠心分離機 MX-100型、(株)トミー精工製)。得られた遠心分離上清4μlを下記の分析条件でのHPLC分析に供した。酵素無添加群の5、24時間目を同様に処理し、アクテオシドの安定性をチェックした(略称:Ez(-))。また反応生成物がDRAであることは、LC/MS分析によって確認した。

実施例2.DRAの製造-2
調製例2で得られた精製アクテオシド4 gを100 mlの50%エタノール水溶液に溶解した。この溶解液全量を2 Lの0.1 M酢酸緩衝液(pH 4.0)に加えて40℃に保ち、ナリンギナーゼ(Penicilliumdecumbens由来、300 units/g、シグマ社製)400 mgを添加した。40℃で3時間撹拌した後、ただちに反応液全量を、水で平衡化した700 mlのMCI GEL CHP-20P(三菱化学株式会社製、75-150 μm)に負荷した。2 Lの水で洗浄した後、2 Lの15%エタノール水溶液、1200 mlの20%エタノール水溶液を流した。続けて、22.5%、25%、27.5%のエタノール水溶液各750 mlで溶出し、それぞれ250 mlずつ3画分に分画した。さらに、 1250 mlの30%エタノール水溶液で溶出し、250 mlずつ5画分に分けた。このうち、27.5%溶出液の第1および第2画分を合せたもの、27.5%溶出液の第3画分から30%溶出液の第3画分までを合せたものを別々に濃縮し、それぞれ438 mgと1.562 gの乾燥物を得た。27.5%溶出液の第3画分から30%溶出液の第3画分の乾燥物を用いてMSおよびNMR解析を行い、DRAであることを確認した。

蒸留水160 mlを40℃にインキュベートし、オリーブ果肉の抽出エキス末(インデナ社製 オレアセレクト(商標)(Batch No.10219))4 gの50%エタノール水溶液20 mlを添加して撹拌し(このときのpH 4.7)、氷酢酸を用いてpH 4.0に調整した。次に、ナリンギナーゼ(Penicilliumdecumbens由来、300 units/g、シグマ社製)40 mgの蒸留水懸濁液20 mlを加え、反応を開始した。0.5分、2分から30分まで2分間隔、60分から210分まで30分間隔に100 μl採取し、除タンパクを目的にして、等量の氷冷したアセトニトリル100 μlを添加して撹拌後、遠心分離をおこなった(10000回転、10分、5℃、微量高速冷却遠心分離機 MX-100型、(株)トミー精工製)。加温210分後の反応液のpHは4.1であった。また、酵素液の代わりに蒸留水を添加して同様に処理した試料を対照とした。得られた遠心分離上清4 μlをHPLC分析に供し、DRAとアクテオシドのピーク面積を求めた。また、DRAとアクテオシドを用いて、50%アセトニトリルによる段階希釈液を調製し、同一条件で分析し、検量線を作成した(DRA検量線のR2=0.9999、アクテオシド検量線のR2=1)。検量線の作成に用いたDRAおよびアクテオシドの標品は、それぞれ実施例2、調製例2で得られたものを使用した。ピーク面積値と検量線から濃度を算出し、下記の算出式により元の試料中(分析時10 mg/ml相当)のDRAおよびアクテオシド含量を求めた。結果を表1に示す。

<算出式>
反応時の試料濃度は20 mg/ml、さらにアセトニトリルで2倍希釈しているので試料濃度は分析時10 mg/ml相当量であることから、含量(%)=100*濃度(μg/ml)/10000(μg/ml)
表1は、DRAおよびアクテオシド含量の経時的変化を示すものである。アクテオシドの減少に伴い、DRAが生成することが確認された。
<抽出>
オリーブ果実のオイル搾りカス2 kgを、80℃の熱水16 Lで2時間抽出した。ナイロンメッシュ(日本理化学器械株式会社製、商品名:NRS-500)でろ過をした後、#131(φ330 mm)ろ紙2枚+400 gハイフロスーパーセル(ナカライ株式会社)を用いた吸引ろ過により搾りカスを除き、抽出液を得た。
<脱ラムノシル反応>
抽出液を40℃まで冷やし、酢酸32 mlを添加しpHを3.93まで下げた。水浴中で40℃に保ちながら、ナリンギナーゼ(Penicilliumdecumben由来、540 units/g、シグマ社製)130 mgを添加し、3.5時間反応した。反応を終了させるため、6 N硫酸35 mlを添加してpHを3.0に調整し、80℃で10分間加熱することにより酵素を失活させた。その後水浴にて40℃以下に冷却し、当量の4 N NaOH水溶液52.5 mlを添加した。
<精製>
50%アセトンにて洗浄し水で平衡化したアンバーライトXAD7-HP樹脂(ローム・アンド・ハース・ジャパン(株))1 L(カラムサイズφ8×20 cm)に、上記の反応液を全量負荷した。2 Lの水で洗浄後、6 Lの15%エタノール水溶液、4 Lの60%エタノール水溶液で順次溶出した。この15%溶出画分と60%溶出画分を各々減圧濃縮した後、凍結乾燥し、それぞれ8.73 gと16.8 gの分画物を得た。このうち、60%溶出画分から得られた分画物を、DRA含有オリーブ抽出物(DRA含量8.9%)として後の動物実験に用いた。
実施例5.DRAの血中抗酸化活性
<測定方法>
DRAの血中抗酸化活性におよぼす影響をラットを用いて評価した。血中抗酸化活性の評価にはFRAP、ORACを用いた。また、DRAおよびアクテオシドは、それぞれ実施例2および調製例2と同様の方法で調製したものを用いた。
実施例6.体内吸収

<測定方法>
各群3匹の血漿を等量混合し均一にした後、血漿90 μlにカタツムリ由来のβ-グルクロニダーゼ/アリルスルファターゼ/酢酸緩衝液(pH 5.0) 90 μlを添加し、37℃で1時間インキュベーションを行った。アセトニトリル900 μlを添加し反応を終了、続いて1%アスコルビン酸水溶液10 μl、内部標準容液10 μlを添加し混合し、遠心分離操作(15,000 rpm、10 min)後の上清を回収した。回収した上清を減圧濃縮後、50% メタノールに再溶解しフィルターろ過してLC-MS/MSに付してアクテオシド、DRAおよびヒドロキシチロソール、カフェ酸の定量を行った。アクテオシド、DRA、ヒドロキシチロソール、カフェ酸量は、ピーク面積と、内部標準として用いたヘスペリジン(Wako)のピーク面積との比により決定した。LC-MS/MS分析条件を以下に示す。
<HPLC分析条件>
