Description
i)クリプテコディニウム属のバイオマスをけん化する工程と、
ii)けん化したバイオマスを、25℃で水1g当たり溶媒0.1g未満の水溶性を有する溶媒で抽出する工程と
によって得られる。
YokochiらのAppl.Microb.Biotechnol.、(1998年)、第49巻、第72〜76頁に記述されているように生成した「DHA含有油」を使用した。これは、一般に公知の工程方法により完全な精製を受けた。以下では、この油を略して「DHA含有油」と示す。
「DHA含有油」+表1に指定するパルミチン酸アスコルビルおよび/またはトコフェロール混合物の量(0.14%(登録商標)Coviox T70;天然トコフェロール混合物を添加)
<実施例1>
抽出物をDGF法F−II1(75)に従って得た。
クリプテコディニウム・コーニー未精製油41.9gを、500ml丸底フラスコに秤量し、メタノール120mlおよび磁気撹拌子と混ぜた。このバッチを、磁気撹拌機で3時間激しく撹拌した。上側のメタノール相を、250ml丸底フラスコにデカントした。油のバッチを、再度メタノール100mlと混ぜ、1時間再洗浄した。油−メタノール混合物を、100ml分液漏斗内に入れ、メタノール相を従前の容器に移した。これをロータリーエバポレーターで濃縮し、オイルポンプによって乾燥した。これにより、抽出物760mgが生成した。「DHA含有油」(対照5;0.1%トコフェロールを含有する。)を2重量%の抽出物と混ぜ、よく混合した。
使用した「DHA含有油」(対照1)を、4重量%の抽出物と混ぜ、よく混合した以外は、実施例2からの脂肪酸組成物と同様に得た。
クリプテコディニウム・コーニー乾燥バイオマスを、直接メタノールで抽出し、この場合、リン脂質の大きな画分も共に抽出し、非常に粘性の生成物となった。
クリプテコディニウム・コーニー乾燥バイオマスを、メタノールで直接抽出し、この場合、リン脂質の大きな画分も共に抽出し、非常に粘性の生成物となった。このような化合物を除去するために、抽出物をアセトンで再度洗浄し、アセトン溶解性成分が、クリプテコディニウム・コーニーアセトン抽出物を形成した。
使用した「DHA含有油」(対照5)を4重量%の抽出物と混ぜ、よく混合した以外は、実施例2からの脂肪酸組成物と同様に得た。
計器:743Rancimat
製造者:Metrohm
計器設定:
方法:(AOCS法Cdl2b−92と同様)
温度:80℃
ガス流量:20L/h
終了基準:終点
<測定の手順および原理>
測定される油(3g)を反応容器に秤量し、加熱ブロックに置き、確定した温度および空気流に曝す。ギ酸などの揮発性酸化生成物が形成し、これが空気チューブを通って測定容器に移動し、その中の蒸留水中で導電電極を用いて導電率を測定する。導電率を終点まで時間をかけて記録する。この曲線から、二次導関数が自動的に形成され、鞍点でその最大値となる。鞍点までの時間を、誘導時間と称する。
上記の物質を、100mlのBrlenmeyerオープンフラスコ内で、暗中室温で所定の時間保管し、その後それらの過酸化物価を分析した。過酸化物価を、AOCS公定法Cd−3d63(米国油化学会)に指定されているように決定した。得られた結果を表2にまとめる。それらは、メタノール抽出物(実施例3)を使用することによって、添加の安定剤なしの「DHA含有油」(対照1)または従来法で安定化させた「DHA含有油」(対照2)と比較して、抗酸化安定性を有意に増加させることができることを示す。このような場合、付加的にトコフェロールを加えることによって抗酸化安定性をさらに増加させることができる。
試料をPhotochem法で測定した。Photochem(登録商標)は、光化学発光(PCL)法に従って作動する。光増感剤を用いて、スーパーオキシドアニオンラジカルが生成し、それらは化学発光物質(例えば、ルミノール)との反応および生じた光の測定を介して検知される。遊離基捕捉剤(抗酸化剤)が試料中に存在するほど、濃度依存的な様式で減衰する光化学発光の光度は強くなる。その結果をトロロックス当量濃度単位で報告する。それぞれの抗酸化剤およびスーパーオキシドジスムターゼの全体の抗酸化能を測定するために、標準化キットを用いて計器を操作する。
