Description
これらの抽出物は、抽出した溶媒のまま用いてもよく、必要に応じて、濃縮、希釈、ろ過などの処理、活性炭等による脱色、脱臭処理をして用いてもよい。更には、抽出した溶液を濃縮乾固、噴霧乾燥、凍結乾燥などの処理を行い、乾燥物として用いてもよい。
ヤーコン葉の乾燥物40gに、精製水1kgを加え、95〜100℃で2時間抽出した。得られた抽出液を濃縮乾燥してヤーコンの熱水抽出物を11g得た。
ヤーコン葉の乾燥物100gに、精製水500gと1,3−ブチレングリコール500gを加え、室温で2週間抽出した。抽出後、ろ過し、ヤーコンの50%1,3−ブチレングリコール抽出物を950g得た。
ヤーコン葉の乾燥物50gに、30%エタノール500gを加え、1週間室温で抽出した。得られた抽出液を濃縮乾燥してヤーコンのエタノール抽出物を7g得た。
製造例1の抽出物10gの水溶液をHP−20カラムにアプライし、水で洗浄した後に50%エタノールで溶出する。得られた溶出液を濃縮乾燥してヤーコンの樹脂カラム吸着物を2.5g得た。
SD系雄ラット(生後7週)の肝臓から抽出した5α−レダクターゼを用い、下記の反応系における条件で測定した。
阻害率(%)=(b/a−b’/a’)/(b/a)×100
a:対照(テストステロンのピーク面積)
b:対照(ジヒドロテストステロンおよびアンドロスタンジオールのピーク面積)
a’:テストステロンのピーク面積(抽出物添加)
b’:ジヒドロテストステロンおよびアンドロスタンジオールのピーク面積(抽出物添加)
