Description
a)α−ヘデリン富化の第1抽出物を供給し、
b)ヘデラコシドC富化の第2抽出物を供給し、そして
c)第1抽出物および第2抽出物を混合して、調整されたヘデラコシドC含量および調整されたα−ヘデリン含量を有する抽出物を得る、
を含むものである。
ることができる。最初に粉砕し、発酵工程に付し、その後に例えばアルコールと水の混合物、例えば30%エタノールで予備膨潤および抽出を行う。最後に、例えば、薄膜蒸発および噴霧乾燥を実施することが可能である。所望のα−ヘデリン含量に依存して、全薬草を発酵させることができる。このようにして、この薬草出発原料に存在する全てのヘデラコシドCは、α−ヘデリンに変換される。一方、原料の薬草の一部だけを発酵させることも可能であり、残りの部分はエタノール中で予備膨潤させるためにだけ混合される。すなわち、これによりα−ヘデリンだけが非常に富化されて存在する。
生物学的同等性試験(BCS)における吸収の研究において、α−ヘデリンは適度に吸収(10〜90%)されることが証明された。同様の条件下、ヘデラコシドCは、膜を透化せず、そのため、α−ヘデリンの形態でのヘデラコシドCの吸収の可能性について調べられた。この目的のために、吸収の研究がラットで実施された。
下記表1に示されるサポニン分布を有する二つの抽出物が、この目的の為に選択された。
がって、以下に、抽出物Bに基いて述べることとする。
ヘデラコシドC: 5〜8%
α−ヘデリン: 3〜5%
最適化ツタの葉抽出物が、ヘデラコシドCおよびα−ヘデリンに対して、適度にバッチ間で差のない含量範囲であることは注目すべきことである。これに関連して、ヘデラコシドCの具体的な含量は、50〜80mg/gであり、α−ヘデリン含量は30〜50mg/gである。これらの仕様と一致させるために、複数の抽出物を混合した。しかしながら、通常の方法で得られた抽出物は、条件付でそのような混合に適している。それというのも、関連活性成分の含量は、しばしば充分に高くないからである。
この抽出工程でα−ヘデリンに対するヘデラコシドCの割合を調整する根拠は、抽出工程においてヘデラコシドCのC28位の糖が特異的に除去されるからである。ヘデラコシドCをα−ヘデリンに変換することは、殆ど定量的に進行するので、実際には如何なるバッチの葉も、α−ヘデリン富化抽出物を製造する出発原料として適している。
α−ヘデリンに対するヘデラコシドCの割合を制御する理由は、抽出工程でヘデラコシドCのC28位に位置する糖の脱離を特異的に抑制することにある。低含量α−ヘデリンを有する薬草のバッチを選択し、使用するように注意を払うべきである。乾燥した薬草に対して、0.5%未満含量のα−ヘデリンの仕様が望ましい。
ヘデラコシドC: 6.37%
α−ヘデリン: 0.85%
2a)および2b)に記載された抽出工程により、それぞれの抽出物が二種のヘデラサポニンのうちの一種を富化された形態で含むツタの葉抽出物を製造することができる。
約7.5%α−ヘデリンを含む抽出物Aの1部 +
約13.0%ヘデラコシドCおよび0.5%α−ヘデリンを含む抽出物Bの1部
→ 6.5%ヘデラコシドCおよび4.0%α−ヘデリンを含む抽出物
Claims (4)
- 以下の工程:
a)ツタの葉に含まれるヘデラコシドCをα−ヘデリンに変換することによって、少なくとも3%のα−ヘデリンを含むα−ヘデリン富化第1抽出物を供給する工程、
b)ヘデラコシドC含量を増大させ、かつα−ヘデリン含量を減少させるために、粉砕されたツタの葉の薬草を、過熱蒸気で蒸熱し、少なくとも5%のヘデラコシドCを含む安定化されたヘデラコシドC富化第2抽出物を供給する工程、そして
c)第1抽出物および第2抽出物を混合して、調整されたヘデラコシドC含量および調整されたα−ヘデリン含量を有する抽出物を得る工程、
を含むことを特徴とする、活性成分としてヘデラコシドCおよびα−ヘデリンを含むツタの葉の抽出物の製造方法。 - α−ヘデリン富化第1抽出物が、少なくとも5%のα−ヘデリンを含むことを特徴とする、請求項1に記載の製造方法。
- ヘデラコシドC富化第2抽出物が、少なくとも10%のヘデラコシドCおよび2%未満のα−ヘデリンを含むことを特徴とする、請求項1または2に記載の製造方法。
- 工程c)で得られる抽出物が、調整された約6.5%のヘデラコシドCおよび調整された約4.0%のα−ヘデリンを含むことを特徴とする、請求項1〜3のいずれかに記載の製造方法。
