Abstract
Description
一方、ホップ酸及びホップ酸に類する酸は以前から細菌阻害剤として認識されている(特許文献1参照)。
また、天然物由来の抗菌剤であるホップ酸(特にベータ酸含有ホップ抽出物)においても、そのリステリア菌に対する抗菌活性の効果は不十分である。さらに、ホップ酸はそれ自体に特有の臭気をもつため、食品に添加する抗菌剤としては適切ではなかった。
すなわち、本発明の目的は、グラム陽性菌に抗菌活性があり、臭気の少ない、食品などに添加しても安全な天然物由来の抗菌剤を提供することである。
[1]シソ科植物抽出物中に含まれる、下記式(1)又は式(2):

[13]上記[1]~[12]の何れかに記載の抗菌剤を、試料中に含有させることを特徴とする抗菌方法。
ローズマリー、セージ、タイム、及びオレガノは、同じ目の植物であり、同じ成分を含んでいる。さらに、これらはシソ科植物であり、同じ科の植物の抽出物であれば、成分の比率は変わったとしても、ほぼ同様の成分を含んでいる。
また、抽出する部位は限定されず、葉、茎、花、及び根からなる群から選ばれる少なくとも1種でもよく、シソ科植物の種類、抽出方法、抽出条件等によって適宜選択することができる。特に、葉又は茎から得られる抽出物が好適である。
通常、シソ科植物、例えばローズマリー1kgに対し、10倍量の上記の溶媒を使用し、5~80℃、好ましくは40~70℃で攪拌抽出し、濾過して濾液を得る。更に、残渣を同様の溶媒で数回洗浄し濾液を得る。これらの濾液を合わせ、濾液と等量の水で沈殿物を析出させ、濾液の1/10量の活性炭を添加し、1時間攪拌し、一昼夜冷所保存し、沈殿物を濾過する。この操作を数回繰り返し、得られた濾液を合わせて減圧濃縮し、非水溶性シソ科植物抽出物を得る。
また、抽出するための液体を用いずに抽出することも可能であり、例えば、シソ科植物を加熱してプレス、圧搾する等によってもシソ科植物抽出物を得ることが出来る。
上記の乳化剤として、例えば、ポリグリセリンラウリン酸エステル、ポリグリセリンミリスチン酸エステル、ポリグリセリンパルミチン酸エステル、ポリグリセリンステアリン酸エステル、ポリグリセリンオレイン酸エステル、ポリグリセリンベヘン酸エステル等のポリグリセリン脂肪酸エステル;ショ糖オクタン酸エステル、ショ糖デカン酸エステル、ショ糖ラウリン酸エステル、ショ糖ミリスチン酸エステル、ショ糖パルミチン酸エステル、ショ糖ステアリン酸エステル、ショ糖オレイン酸エステル等のショ糖脂肪酸エステル;ポリソルベート40、60、65、80等のポリソルベート類;レシチン分解物等が挙げられ、これらは2種以上を併用してもよい。乳化剤の含有量は限定されないが、テルペノイド-1及びテルペノイド-2の合計量に対して、通常0.001~1000重量%、好ましくは0.01~90重量%、より好ましくは0.1~50重量%、更に好ましくは1~20重量%である。

特に、本発明の抗菌剤とホップ酸などのホップ抽出物とを併用すれば、ホップ酸が有する特有の臭気が低減されるとともに、高い抗菌性を有することになり、天然物由来の抗菌剤として有用である。
(非水溶性ローズマリー抽出物の製造)
ローズマリー1kgに50重量%含水エタノール10Lを加えて3時間加熱還流し、温時に濾過して濾液を得た。残渣を50重量%含水エタノール6Lで同様に抽出する操作を更に2回繰り返して濾液を得た。これらの濾液を合わせ、水5Lを加えて沈殿物を析出させた。これに活性炭100gを加え、1時間撹拌し、一夜冷所で保存した後に濾過して沈殿と活性炭の混合物を得た。この混合物にエタノール4Lを加え、3時間加熱還流し、温時に濾過して濾液を得た。残渣をエタノール2.4Lで同様に抽出する操作を更に2回繰り返して濾液を得た。これらの濾液を合わせ、減圧濃縮してエタノールを留去し、粉末状の非水溶性ローズマリー抽出物(カルノソール及びカルノジック酸の含有量:24.9重量%)を得た。
非水溶性ローズマリー抽出物を、ODS(オクタデシルシリル化シリカゲル)カラム(Φ30mm×120mm)を用いて、溶離液としてアセトニトリルを流した後、樹脂中に残った成分を、クロロホルム/メタノール(体積比)=100/0、99/1で押し出し、クロロホルム100%で流した時の粗分画ローズマリー抽出物を得た。さらに、クロロホルム/メタノール(体積比)=99/1で洗浄後、2種類の成分が得られた。これら成分を1H-NMRによる構造解析を行った結果、一つはフェルギノール(テルペノイド-1;式(1)の化合物)で、もう一方は天然物では新規の成分(テルペノイド-2;式(2)の化合物)であることが分かった。
新規成分であるテルペノイド-2のNMR(1H-NMR)データおよび質量分析データは次のとおりである。
非水溶性ローズマリー抽出物の単離成分(テルペノイド-1、テルペノイド-2)をDMSO(ジメチルスルホキシド)で2,000ppmの濃度に溶解し、抗菌活性試験用の各サンプルとした。
抗菌試験は、リステリア・モノシトジェネス(Listeria monocytogenes)JCM2873株を用いて、次のとおり行った。
Mueller Hinton Broth(MHB)培地8.95mlを試験管に入れ、オートクレーブで滅菌処理した。培地濃度は、サンプル50μlを加えた時に規定濃度となるように調整した。
MHB培地で上記菌株を37℃で1日間振盪培養したものを、MHB培地で適当な菌濃度(3.1×104cfu/ml)に希釈した。
上記(1)で調製したMHB培地8.95mlの入った試験管に、サンプル50μlと、上記(2)で調製した菌液1mlを加えて撹拌後(試験時の単離成分濃度は10ppm)、37℃で24h静置した。なお、サンプルの代わりに、滅菌水及びエリスロマイシン(エタノールで2,000ppmの濃度に溶解)を加えたものを、それぞれ、陰性対照及び陽性対照とした。
37℃で24h静置した試験管から培養液を1白金耳採取し、Mueller Hinton寒天培地に塗抹した。37℃/2日培養後、寒天培地上のコロニー形成の有無及び程度を判定した。
(抽出成分の分画)
実験例1と同様の方法にて粉末状の非水溶性のローズマリー抽出物902mgを得た。これを少量のアセトニトリルに溶解してODS(オクタデシルシリル化シリカゲル)30gのカラム(Φ30mm×120mm)に注入した後、水/アセトニトリル混合液を用いたステップグラジエント法によって溶出した。溶出液の混合比率は、水/アセトニトリル(体積比)=80:20、60:40、40:60、20:80、0:100とし、各150mlを使用した。次に、カラムをクロロホルム150mlで溶出後、さらにメタノール150mlで溶出した。
水/アセトニトリル(体積比)=60:40、40:60、20:80の溶出液は、それぞれシリカゲルの薄層クロマトグラフィー(TLC)で分画し、各成分をNMR(1H-NMR)で分析することにより、表1の通り同定した。
アセトニトリル(100%)、クロロホルム及びメタノールの溶出液は全てを混合して濃縮乾固し、さらに以下のシリカゲルによる分画を行った。すなわち、濃縮乾固物をクロロホルムに溶解してシリカゲル15gを充填したカラムに注入した後、クロロホルム/メタノール混合液を用いたステップグラジエント法によって溶出した。溶出液の混合比率は、クロロホルム/メタノール(体積比)=100:0、99:1、98:2、97:3、96:4、95:5、0:100とし、各150mlを使用した。
各溶出液は濃縮乾固した後、高速液体クロマトグラフィー(HPLC)で更に分画を行った。HPLCはODSカラムを用い、水/メタノール混合溶液(体積比10:90)で溶出した。クロロホルム/メタノール(体積比)=98:2、96:4、0:100の溶出液の乾固物から、NMR(1H-NMR)で分析することにより、表1の通り同定した。
上記で得られた各単離成分をジメチルスルホキシド(関東化学社製)で希釈し、それぞれ分画品濃度(重量%)として2%、1%、0.5%の3種類に調製した。ポジティブコントロールとしてエリスロマイシン(和光純薬工業社製)をエタノール(純正化学社製)で溶解し、1000ppm、500ppm、250ppmの3種の濃度に調製した。ネガティブコントロールとして滅菌水を使用した。
抗菌試験は、リステリア・モノシトジェネス(Listeria monocytogenes)ATCC49594株を用いて、次のとおり行った。
ブレインハートインヒュージョン培地(BHI)(日水製薬社製)8.9mlを試験管に入れ、オートクレーブ(トミー精工社製、TOMY BS-325)で処理した。培地濃度は、上記の各試験液を0.1ml加えたときに規定濃度となるように調製した。
BHI培地で上記菌株を37℃で1日間振盪培養したものを、BHI培地で適当な菌濃度(2.0×103cfu/ml)に希釈した。
上記(1)で調製したBHI培地8.9mlの入った試験管に、調製した試験液0.1mlと、上記(2)で調製した菌液1mlを加えて撹拌後、30℃で24h静置した。
30℃で24h(時間)静置した試験管の培養液の濁度を、濁度計(タイテック社製、ミニフォト518R)を用いて波長660nmにて測定した。試験液の代わりにジメチルスルホキシドを0.1ml加えた培養液の場合の濁度値をAとした場合に、以下の式より阻害率を算出した。
阻害率(%)=〔(A-[培養液の濁度])/A〕×100
30℃で24h静置した試験管の培養液を、リン酸緩衝溶液(PBS)で希釈し、BHIの寒天培地に塗抹した。これを37℃で24h培養した後、寒天培地上の菌数を顕微鏡観察によって測定した。なお、PBSでの希釈は、24h後に顕微鏡にて菌数を測定可能な濃度となるように、予め培養液を102~109倍の範囲で適宜希釈した(24h後の菌数は、予めPBSで希釈した比率に応じて補正した)。
テルペノイド-1、及びテルペノイド-2以外の抽出成分について、テルペノイド-1、及びテルペノイド-2と同様の条件で評価した阻害率及び菌の増殖性の結果を表3に示す。この結果、7α-エトキシロスマノール、カルノソール、12-メトキシ-trans-カルノジック酸、ロスマノール、エピロスマノール、及びベツリン酸では、何れもリステリア・モノシトジェネス(Listeria monocytogenes)への抗菌活性が低いか、又は抗菌活性が見られなかった。
昨今のエネルギー削減、地球環境対策、人口増加対策、食料問題等を勘案すれば、本発明の抗菌剤を用いることにより、特に新鮮な飲食品に対する腐敗を抑制することが可能であり、飲食品を有効に活用することが可能となる。すなわち、本発明の抗菌剤は、畜産、水産、食品加工、飲食品製造、飲食品販売、流通、医療、衛生など種々の産業において有用である。
