Abstract
Description
[1]ローヤルゼリーを水で溶出し残差を得ること、得られた残差を50%エタノールで溶出し残差を得ること、次いで、得られた残差を99.5%エタノールで溶出し溶出各分を得ることを含む、ローヤルゼリー分画の製造方法、
[2]ローヤルゼリーを含む、海馬のAβオリゴマー分解システムを回復・強化するための組成物、
[3] ローヤルゼリーが、[1]の方法によって得られたローヤルゼリー分画である、[2]に記載の組成物。
海馬での記憶形成と関連する転写活性を指標にローヤルゼリーの作用を調べてみた。ネズミの脳の海馬から神経細胞を取り出して2週間培養し、その後培養液に新鮮なローヤルゼリー原乳を添加すると、海馬の神経細胞は応答して転写活性を上昇させた。さらに活性成分を濃縮して神経細胞を処置すると、応答は一層強くなることが観察された。今回の研究から、ローヤルゼリーは記憶と関連する海馬神経細胞の活性を強化する作用をもつことが示された。
1.オープンカラム(直径25mm×全長550mm)にダイヤイオン(HP−20、20g)を充填し、2〜3時間水を流し続け平衡化させた。
2.上清(フラクション3)をエバポレーターで1ml〜2mlになるまで濃縮し、全量をカラムに充填した。
3.水(100ml)を少しずつカラムに加え、溶出させ、画分を得た。
4.50%エタノール(100ml)を少しずつカラムに加え、溶出させ、画分を得た。
5.99.5%エタノール(100ml)を少しずつカラムに加え、溶出させ、画分を得た。
6.メタノール(100ml)を少しずつカラムに加え、溶出させ、各分を得た。
7.上記の2〜5で得られた画分を減圧下にて溶媒を留去し、収量を測定した。
1.48時間後に採取した新鮮なローヤルゼリー原乳に濃度依存的なCRE依存的転写促進活性が認められた。
2.海馬神経細胞培養系においてローヤルゼリー原乳にCRE依存的転写促進活性を認めた。
3.100μg/mlのローヤルゼリー原乳のフラクション2及び3に、とりわけ、フラクション3において極めて強いCRE依存的転写促進活性が認められた。しかも、その転写促進効果は、30μMノビレチンよりも強力であり、コントロール群の7倍であった。
4.ローヤルゼリーのフリーズドライ粉末に原乳のフラクションを添加すると、転写活性は増大した。
5.ローヤルゼリー原乳及びフラクション3は、Aβオリゴマーの抑制作用を抑制した。
