Description
八丈島原産の、播種後から開花前までのアシタバの茎を切断し、滲出した樹液(黄汁)を採取した。この樹液を濾過し、濾液を入れた容器を沸騰水中に30分間浸漬(加熱殺菌処理)し、アシタバ黄汁原液を得た。加熱殺菌処理したアシタバ黄汁原液70gとサイクロデキストリン粉末30gとを均一に混合し、得られた混合物の凍結乾燥を行い、アシタバ黄汁の乾燥粉末を得た。
上記加熱殺菌したアシタバ黄汁を1〜2時間静置すると、水性画分と油性画分とに分離した。上面に分離した水性画分を回収した。
上記調製例2で得たアシタバ黄汁乾燥粉末およびアシタバ黄汁水性画分を用いて、耐熱性好酸性菌に対する抗菌作用を検討した。耐熱性好酸性菌として、Alicyclobacillus acidocardarius IFO323株およびAlicyclobacillus acidoterrestris ATCC49025株を用いた。これらの株を、以下の液体培地:酵母エキス2.0g、硫酸アンモニウム0.4g、硫酸マグネシウム・7水和物1.0g、塩化カルシウム・2水和物0.5g、リン酸二水素カリウム1.2g、グルコース2.0g、および水1L(硫酸にてpHを3.5に調整)中で培養した。
アシタバ黄汁乾燥粉末を、それぞれ、0.001mg/mL、0.005mg/mL、0.01mg/mL、および0.05mg/mL含むPDA寒天培地を調製した。また、アシタバ黄汁水性画分を、それぞれ、0.1μL/mL、0.5μL/mL、1μL/mL、5μL/mL、および10μL/mL含むPDA寒天培地を調製した。なお、PDA寒天培地は、次の組成を有している:パールコアPDAプレート:バレイショ浸出液200g、グルコース20g、寒天15g、蒸留水1L。
(アシタバ黄汁の水抽出物の調製)
上記調製例1で得たアシタバ黄汁の乾燥粉末を、5mg/mL、25mg/mL、50mg/mL、および250mg/mLとなるように蒸留水に分散させ、室温で2時間、ときどき撹拌しながら放置し、遠心分離にて上清(水抽出物)を調製した。
上記調製例1で得たアシタバ黄汁の乾燥粉末を、5mg/mL、25mg/mL、50mg/mL、および250mg/mLとなるように酢酸エチルに分散させ、室温で2時間、ときどき撹拌しながら放置し、遠心分離にて上清(酢酸エチル抽出物)を得た。
上記調製例2で得たアシタバ黄汁の水性画分を、蒸留水で2倍および5倍に希釈した。
上記調製した各試料(アシタバ黄汁の水抽出物、酢酸エチル抽出物、水性画分希釈物)、ポジティブコントロールとして5mg/mLおよび50mg/mLのゲンタマイシン、並びにネガティブコントロールとして蒸留水および酢酸エチルを、それぞれ10μLとり、直径6.35mmの滅菌ペーパーディスクに含ませた後、常温で乾燥し、試料ディスクとした。上記実施例1に記載の液体培地で培養し、洗浄および希釈した耐熱性好酸性菌をPDA寒天培地上に塗布し、その上に試料ディスクを密着させ、好気条件下、50℃で24時間培養し、形成された阻止円の直径を測定した。結果を表3に示す。
Claims (2)
- アシタバ黄汁中の水性画分を含む、耐熱性好酸性菌に対する抗菌剤。
- アシタバ黄汁の水抽出物を含む、耐熱性好酸性菌に対する抗菌剤。
