一方、特許文献4に記載のクルクミン複合体については、食品の着色剤として利用されるものであって、クルクミン及び/又はその類縁体の体内への吸収性が向上することについては示されていない。
従って、本発明の課題は、クルクミン及び/又はその類縁体の経口吸収性が改善され、かつ簡便で安価に製造できる経口摂取用組成物を提供することにある。
〔2〕クルクミン及び/又はその類縁体が、クルクミン又はウコン色素である〔1〕記載の複合体。
〔3〕水溶性セルロース誘導体が、メチルセルロース、エチルセルロース、ヒドロキシプロピルセルロース、ヒドロキシプロピルメチルセルロース、カルボキシメチルセルロース及びカルボキシメチルセルロース塩から選ばれる成分である〔1〕又は〔2〕記載の複合体。
〔4〕(A)クルクミン及び/又はその類縁体と(B)水溶性セルロース誘導体の含有比率(A/B)が、0.02~10である〔1〕~〔3〕のいずれかに記載の複合体。
〔5〕クルクミン及び/又はその類縁体と水溶性セルロース誘導体とを含有する水-有機溶剤混合溶液から、溶媒を除去することにより得られるものである〔1〕~〔4〕のいずれかに記載の複合体。
〔6〕クルクミン及び/又はその類縁体が、非晶質である〔1〕~〔5〕のいずれかに記載の複合体。
〔7〕〔1〕~〔6〕のいずれかに記載の複合体を含有する経口摂取用組成物。
〔8〕クルクミン及び/又はその類縁体と水溶性セルロース誘導体とを水-有機溶剤混合溶媒に溶解させる工程と、該溶液から水及び有機溶剤を除去する工程と、を有することを特徴とする、クルクミン及び/又はその類縁体と水溶性セルロース誘導体との複合体の製造方法。
〔9〕クルクミン及び/又はその類縁体を有機溶剤に溶解する工程と、水溶性セルロース誘導体を水に溶解する工程と、クルクミン及び/又はその類縁体を含有する有機溶剤溶液と水溶性セルロース誘導体を含有する水溶液とを混合する工程と、当該混合溶液から水及び有機溶剤を除去する工程と、を有することを特徴とする、クルクミン及び/又はその類縁体と水溶性セルロース誘導体との複合体の製造方法。
なお、クルクミンには、互変異性体であるケト型及びエノール型のいずれも含まれる。
これらの水溶性セルロース誘導体のうち、ヒドロキシプロピルセルロース、ヒドロキシプロピルメチルセルロースがより好ましく、ヒドロキシプロピルメチルセルロースがさらに好ましい。
より具体的には、(A)クルクミン及び/又はその類縁体を有機溶剤に溶解する工程と、(B)水溶性セルロース誘導体を水に溶解する工程と、クルクミン及び/又はその類縁体を含有する有機溶剤溶液と水溶性セルロース誘導体を含有する水溶液とを混合する工程と、当該混合溶液から水及び有機溶剤を除去する工程と、を含む方法により製造される。
(各種複合体の調製)
(調製方法A:スプレードライヤーを用いて乾燥)
70又は80%(v/v)エタノール溶液400mLに三栄源エフ・エフ・アイ社から供与されたクルクミン含有量が91.2%(w/w)のウコン抽出物粉末(Lot.NCTH0012012)1.10~8.77g(クルクミン量として1.0~8.0g)とヒドロキシプロピルメチルセルロース(HPMC:メトローズSE-06又はSE-03、信越化学工業社製)又はヒドロキシプロピルセルロース(HPC:SSL、日本曹達社製)0.2~64.8gとを添加し、約80℃に加温しながら撹拌することでクルクミン-ヒドロキシプロピルメチルセルロース複合体又はクルクミン-ヒドロキシプロピルセルロース複合体含有溶液を調製した。
また、前記クルクミン-ヒドロキシプロピルメチルセルロース複合体含有溶液に添加剤としてデキストリンを加えて溶解させることでデキストリンを含むクルクミン-ヒドロキシプロピルメチルセルロース複合体を調製した。
次いで、これら溶液をN2ガス密閉循環型噴霧方式二流体ノズル式スプレードライヤー(Pulvis Mini-SprayGS-31、ヤマト科学社製)を用いて、inlet temperature 140℃、outlet temperature 80~90℃、spray pressure 0.10~0.13MPa、feed rate 10mL/min、orifice pressure 75mmHgの条件で噴霧乾燥することでクルクミン-ヒドロキシプロピルメチルセルロース複合体又はクルクミン-ヒドロキシプロピルセルロース複合体を調製した。
(調製方法B:エバポレーターを用いて乾燥)
70(v/v)エタノール溶液200又は400mLに三栄源エフ・エフ・アイ社から供与されたクルクミン含有量が91.2%(w/w)のウコン抽出物粉末(Lot.NCTH0012012)1.10又は2.19g(クルクミン量として1.0又は~2.0g)とヒドロキシプロピルメチルセルロース(HPMC:メトローズSE-06、信越化学工業社製)0.2、4、6又は10gとを添加し、約80℃に加温しながら撹拌することでクルクミン-ヒドロキシプロピルメチルセルロース複合体含有溶液を調製した。
次いで、該溶液をエバポレーター(rotary evaporator N-1000、EYELA社製)内に入れ、これを減圧しながら80℃に保持して溶媒を留去することで乾固させ、乾燥物を回収した。また、該乾燥物を乳鉢に入れて乳棒で粉砕することでクルクミン-ヒドロキシプロピルメチルセルロース複合体を調製した。
(各種複合体の経口吸収性)
(1)供試動物
供試動物は、6週齢のSDラット(雄性、体重170g~260g、日本チャールス・リバー社)を用いた。
投与方法は、投与前12時間以上絶食させた供試動物(n=3又は5)に、上記で調製した各種複合体(実施例1~13)をそれぞれクルクミン濃度1mg/mLとなるように所定量を注射用水に添加して20mLにメスアップし、超音波発生装置を用いて混合した後、クルクミン投与用量が10mg/kg(投与試験例1~13)又は50mg/kg(投与試験例14)となるように経口ゾンデを用いて強制的に経口投与した。
なお、クルクミン原末(比較試験例1)、クルクミン原末とヒドロキシプロピルメチルセルロース粉末又はヒドロキシプロピルセルロース粉末とを単に物理的に混合(クルクミン:HPMC=1:3又はクルクミン:HPC=1:3)した物理混合物(比較試験例2、3)又は微粒子化したクルクミノイドとガディガムとを組み合わせたウコン色素組成物であるCR-031P粉末(セラバリューズ社製)(比較試験例4、5)を投与した場合を対照とした。
血漿中クルクミン及び/又はその類縁体濃度の測定は、投与開始30分、1時間及び2時間に供試動物の頸静脈から無麻酔下で約0.5mL採血を行うことで得たヘパリン血漿を用いて、以下の方法によって測定した。
採血した血漿20μLに0.1M酢酸緩衝液(pH5.0)100μLとβ-グルクロニダーゼ溶液(約68,000units/mL)10μLを加え、37℃で1時間保持した。その後、内部標準液であるメプロニル20ng/mLが含まれる50%(v/v)メタノール10μLとクロロホルム0.5mLとを添加し、ボルテックスミキサーを用いて1分間撹拌後、超音波発生装置を用いて15分間混合することで調製した抽出処理液を遠心分離(13,000×g、5分間、室温)によってクロロホルム層と水層とに分離した。なお、この抽出処理を2回繰り返した。次いで、該クロロホルム層を採取し、これを減圧遠心濃縮機を用いて溶媒を留去することで乾固させ、ここに50%(v/v)メタノール100μLを添加した後、遠心分離(13,000×g、5分間、室温)して上清液を回収した。
上記で調製した上清液2μLをLC-MS/MS(島津社製)を用いて分析を行うことで血漿中クルクミン濃度を測定した。なお、LC-MS/MS分析条件は、LCカラムがAtlantis T3(2.1×150mm,3μm,Waters社製)、カラム温度が40℃、流速が0.2mL/min、移動相がA:0.1%ギ酸水溶液、B:0.1%ギ酸/アセトニトリルとし、以下の条件でグラジェント溶出を行った。また、MS分析条件は、イオン化モードがElectron Spray thermo ionization(ESI)、Positive、測定モードがMultiple Reaction Monitoring(MRM)とし、クルクミン369.1→177.2(m/z)、メプロニル270→119(m/z)で評価した。
一方、試料中に含まれるクルクミン量を定量するために使用する検量線の作成は、クルクミンが1.0、2.0、3.9、7.8、15.6、31.3、62.5、125又は250ng/mLを含む50%(v/v)メタノール溶液(クルクミン標準液)90μLにメプロニル20ng/mLを含む50%エタノール溶液10μLを添加することで調製した各種標準溶液(クルクミン濃度9~225ng/mL)を用いて上記同様の条件で測定することで行った。
血漿中のクルクミン濃度(ng/mL)、最高血中濃度(Cmax(ng/mL))及び血中濃度-時間曲線下面積(AUC(ng/mL・0-2hr))を表3~4及び図1~5に示す。
表3~4及び図1~5から明らかなように、本発明の複合体は、クルクミン単独投与、及びクルクミンとHPMCとの混合物の投与に比べて顕著に経口吸収性が向上している。また、クルクミンとガティガム混合微粉砕物(CR-031P)と比べても経口吸収性が向上していた。
各種複合体中の非晶質クルクミンの安定性を調べることを目的に、上記で調製した各複合体(実施例1~5及び10~11)をそれぞれアルミパウチに入れて40℃で保持し、これら複合体中のクルクミンの結晶性を粉体X線回折装置(RINT-UltimaIII、Rigaku社製)を用いて経時的(試験開始時(0M)、試験開始1ヶ月後(1M)、試験開始2ヶ月後(2M)及び試験開始4ヶ月後(4M))に調べた(図6~12)。
なお、対照として、ウコン抽出物粉末(対照A:原末)、ウコン抽出物粉末をエタノールに溶解させた後、上記調製方法Aに記載した方法と同様の条件でスプレードライしたウコン抽出物粉末SD品(対照B:原末SD品)及びウコン抽出物粉末とヒドロキシプロピルメチルセルロース又はヒドロキシプロピルセルロースとをウコン抽出物中のクルクミンと該水溶性セルロース誘導体との重量比で9:1~1:9となるように単に混合して調製した物理混合品(対照C1~5及び10~11)とした。
クルクミンとヒドロキシプロピルメチルセルロースの比率が9:1の複合体(実施例1)及び3:1の複合体(実施例2)の場合、試験開始時(0M)にはクルクミン由来の結晶性を示すピークが認められず、複合体中のクルクミンは非晶質であった。40℃で1ヶ月以上保持した場合(1M、2M及び4M)には結晶性を示すピークが認められた(図6及び7)が、そのピークは若干であった。
クルクミンとヒドロキシプロピルメチルセルロースの比率が1:3の複合体(実施例10)の場合、試験開始時(0M)にはクルクミン由来の結晶性を示すピークが認められず、複合体中のクルクミンは非晶質であった。40℃で1ヶ月以上保持した場合(1M及び2M)には結晶性を示すピークが認められた(図11)が、そのピークは若干であった。
