Description

本発明は、べにふうきエキスを有効成分とするポリフェノール類化合物の吸収促進剤、及びその利用に関するものである。   The present invention relates to an absorption accelerator for polyphenol compounds containing Benifuuki extract as an active ingredient, and use thereof.

緑茶は日本人が古くから親しんできた飲料であり、近年では容器詰緑茶飲料の普及もあって、非常に多く飲用されている。緑茶には茶カテキンと総称される一群のフラバノール化合物が含まれており、抗腫瘍効果、抗血小板凝集効果、抗高血圧効果、抗肥満効果 、抗酸化効果など、健康にとって有益な多くの機能を有することが知られている。しかし、茶カテキンを経口的に摂取しても一般に吸収率が低く、摂取量の極一部分しか体内に吸収されない。このため、茶カテキンの吸収性を高める工夫が多くなされてきた。   Green tea is a drink that Japanese people have been familiar with for a long time, and in recent years, the use of packaged green tea drinks has become widespread and has been drunk a great deal. Green tea contains a group of flavanol compounds collectively called tea catechins, and has many beneficial functions for health, such as antitumor effects, antiplatelet aggregation effects, antihypertensive effects, antiobesity effects, and antioxidant effects. It is known. However, even if tea catechin is taken orally, the absorption rate is generally low, and only a very small part of the intake is absorbed into the body. For this reason, many attempts have been made to increase the absorbability of tea catechins.

例えば、下記特許文献1には、緑茶飲料中の茶カテキン濃度を高め、茶カテキンの摂取量を多くすることにより、茶カテキンの吸収量ならびに血中濃度を高める方法が開示されている。しかし、この方法では茶カテキン濃度が高くなることにより、茶カテキンに特有の苦味・渋味が強くなるため、緑茶飲料中に添加できる茶カテキンの量には限界があるほか、原料の茶カテキンを多量に使用することになるため、経済的な負担が増加するなどの問題があった。このほか、下記特許文献2には、飲料中のアルコール沈殿性物質の量を低減することにより茶カテキンの吸収率を高める方法が開示されている。しかし、この方法はアルコール沈殿性物質量を一定の含有量以下とするために精製、酵素処理等の操作を追加しなければならず、製造工程が煩雑になりコストが嵩むという問題があった。また、紅茶飲料中に含まれる茶カテキンのエピ体と非エピ体の含有量を一定の条件を満たすように配合することにより茶カテキンの吸収率を高める方法が知られている(下記特許文献3、及び特許文献4参照)。しかし、エピ体および非エピ体の含有量に関する要件は、一般家庭で飲用される緑茶等では通常満たされており、容器詰飲料のうちの紅茶飲料以外の飲食品への応用は難しいと考えられる。更には、下記特許文献5には、緑茶中のエピガロカテキンガレートおよびカフェインの含有量が所定の関係を満たすように配合することによりエピガロカテキンガレートの吸収を促進する方法が開示されている。しかし、合成吸着剤カラムを用いたクロマト処理等でカフェインを除去する処理を行わなくてはならず、本来の味や風味の成分までも損ねてしまうという問題があった。

For example, Patent Document 1 below discloses a method for increasing the amount of tea catechin absorbed and the blood concentration by increasing the concentration of tea catechin in the green tea beverage and increasing the intake of tea catechin. However, this method increases the tea catechin concentration, which increases the bitterness and astringency unique to tea catechins, so there is a limit to the amount of tea catechins that can be added to green tea beverages. There are problems such as an increase in economic burden due to the large amount of use. In addition, Patent Document 2 below discloses a method for increasing the absorption rate of tea catechins by reducing the amount of alcohol-precipitating substance in the beverage. However, in this method, in order to keep the amount of alcohol-precipitating substance below a certain content, operations such as purification and enzyme treatment have to be added, and there is a problem that the production process becomes complicated and the cost increases. Moreover, the method of raising the absorption rate of tea catechin is mix | blended by mix | blending the content of the epi catechin of tea catechin contained in a black tea beverage, and non-epi isomer so that a fixed condition may be satisfy | filled (the following patent document 3). And Patent Document 4). However, the requirements regarding the content of epi- and non-epi-forms are usually satisfied for green teas and the like that are drunk in ordinary households, and it is considered difficult to apply to foods and beverages other than tea beverages among packaged beverages. . Furthermore, the following Patent Document 5 discloses a method for promoting the absorption of epigallocatechin gallate by blending the contents of epigallocatechin gallate and caffeine in green tea so as to satisfy a predetermined relationship. . However, there has been a problem that the caffeine must be removed by chromatography using a synthetic adsorbent column, and the original taste and flavor components are also impaired.

上述したように、緑茶には茶カテキンと総称される一群のフラバノール化合物が含まれており、抗腫瘍効果[Katiyar SK and Mukhtar H (1996) Int J Oncol 7:133-141; Bu-Tian JI et al. (1997) Int J Cancer 70:255-258; Su LJ and Arab L(2002) Public Health Nutr 5:419-425]、抗血小板凝集効果[Duffy SJ et al. (2001) Arterioscler Thromb Vasc 21:1084-1089]、抗高血圧効果 [Negishi H et al. (2005) J Nutr 134:38-42]、抗肥満効果 [Nagao T et al.(2005) Am J Clin Nutr 81:122-9; Murase T et al. (2002) Int J Obes 26:1459-64]、抗酸化効果[ Sano M et al. (2003) J Agric Food Chem 51:2912-2916] など、健康にとって有益な多くの機能を有することが知られている。緑茶中に含まれる主要な茶カテキンは、カテキン、エピカテキン、ガロカテキン、エピガロカテキン、カテキンガレート、エピカテキンガレート、ガロカテキンガレート、エピガロカテキンガレートの8種類であるが、その中でも緑茶カテキンの約50%を占めるエピガロカテキンガレートは、他と比較して高い生理活性を有するとされている。   As mentioned above, green tea contains a group of flavanol compounds, collectively called tea catechins, that have antitumor effects [Katiyar SK and Mukhtar H (1996) Int J Oncol 7: 133-141; Bu-Tian JI et al. (1997) Int J Cancer 70: 255-258; Su LJ and Arab L (2002) Public Health Nutr 5: 419-425], antiplatelet aggregation effect [Duffy SJ et al. (2001) Arterioscler Thromb Vasc 21: 1084-1089], antihypertensive effect [Negishi H et al. (2005) J Nutr 134: 38-42], anti-obesity effect [Nagao T et al. (2005) Am J Clin Nutr 81: 122-9; Murase T et al. (2002) Int J Obes 26: 1459-64] and antioxidant effect [Sano M et al. (2003) J Agric Food Chem 51: 2912-2916] It has been known. The main tea catechins contained in green tea are eight types of catechin, epicatechin, gallocatechin, epigallocatechin, catechin gallate, epicatechin gallate, gallocatechin gallate, and epigallocatechin gallate. Epigallocatechin gallate occupying 50% is said to have higher physiological activity than others.

しかし、ポリフェノール類化合物である茶カテキンは一般に吸収率が低く、ことにエピガロカテキンガレートの吸収率は非常に低いため、摂取量の極一部分しか体内に吸収されない [ラットでの研究結果は Chen L et al. (1997) Drug Metab Dispos 25:1045-1050; Zhu M et al.

(2001) Cancer Epidemiol Biomarkers Prev 10:53-58; Vaidyanathan and Walle (2001) Pharm Res (NY) 18:1420-1425]。   However, tea catechins, which are polyphenolic compounds, generally have a low absorption rate, especially epigallocatechin gallate absorption rate, so only a very small part of the intake is absorbed into the body. et al. (1997) Drug Metab Dispos 25: 1045-1050; Zhu M et al. (2000) Planta Med 66: 444-447] [Research results in humans are Warden BA et al. (2001) J Nutr 131: 1731-1737; Chow et al.

本発明によれば、べにふうきエキスを摂取することにより、ポリフェノール類化合物、例えば茶カテキンの吸収率を顕著に向上させることができる。したがって、少量のポリフェノール類化合物、例えば茶カテキンの摂取によっても従来と同等あるいはそれ以上の健康増進効果を得ることが可能となる。また、吸収率が高まれば、これらの血中濃度を有効濃度に到達させるために必要な飲食品中の配合量を従来よりも少なくすることができるので、ポリフェノール類化合物、例えば茶カテキンに特有の苦味・渋味などを感じさせない、又はそれらの低減された、摂取しやすい飲食品を提供することができる。べにふうきエキスは単独で吸収促進効果を有するが、特にポリフェノール類化合物の源として茶エキスを摂取する場合には、茶エキス自体に付随した吸収阻害効果を打ち消して、茶エキスからのポリフェノール類化合物の吸収率を顕著に向上させることができる。   According to the present invention, the absorption rate of polyphenol compounds such as tea catechin can be remarkably improved by ingesting Benifuuki extract. Therefore, even by taking a small amount of a polyphenol compound, for example, tea catechin, it is possible to obtain a health promoting effect equivalent to or higher than that of the prior art. In addition, if the absorption rate is increased, the amount of these ingredients in foods and drinks required to reach the effective concentration in blood can be reduced as compared with the conventional one, so that it is unique to polyphenol compounds such as tea catechins. It is possible to provide a food and drink that does not feel bitterness, astringency, or the like, or that is reduced and that is easy to ingest. Benifuuki extract has an absorption promoting effect by itself, but especially when taking tea extract as a source of polyphenol compounds, it absorbs polyphenol compounds from tea extract by canceling the absorption inhibition effect associated with tea extract itself. The rate can be significantly improved.

以下、本発明について好ましい態様を挙げて、更に詳細に説明する。   Hereinafter, preferred embodiments of the present invention will be described in more detail.

本発明に用いられるべにふうきエキスは、茶の品種のひとつであるべにふうき種(例えば農林水産省品種登録番号:第4591号)の茶葉から得られたものである。原料としては、通常の緑茶に製したものなどを用いることができる。エキスの調製は、上記べにふうきの茶葉を水あるいは熱水等の溶媒を用いて抽出することによって行うことができる。例えば、べにふうきの茶葉1質量部に対し、5〜100質量部の溶媒を加え、室温〜100℃程度の温度で、1〜120分間程度抽出する方法が挙げられる。なお、本発明において「べにふうきエキス」とは、ポリフェノール類化合物の吸収を促進する有効成分が茶葉に包含されている状態をも含む概念であり、溶媒で抽出したエキスのかわりに茶葉の乾燥粉末等を摂取してもよく、ポリフェノール類化合物を含有する飲食品用原料又は飲食品素材用原料に添加し、又は配合して用いてもよい。   The Benifuuki extract used in the present invention is obtained from the tea leaves of Benifuuki seeds (for example, Ministry of Agriculture, Forestry and Fisheries Variety Registration No. 4591) which is one of the tea varieties.

以下に例を挙げて本発明を具体的に説明するが、これらの例は本発明の範囲を限定するものではない。   The present invention will be specifically described below with reference to examples, but these examples do not limit the scope of the present invention.

<試験例1>
まず、3ロットのべにふうきエキス(アサヒ飲料株式会社製べにふうき茶熱水抽出物; ロット1[i]、ロット2[ii]、ロット3[iii])、および2ロットの、食品原料として通常用いられている緑茶エキス(以下、「緑茶エキス」という。)(三栄源エフエフアイ株式会社製緑茶熱水抽出物; ロット4[iv]、ロット5[v])について、ラットによるEGCGの吸収性を比較した。具体的には、EGCG濃度が1 mMとなるように調製したそれぞれの投与液をラットへ単回強制経口投与し、投与後の時間経過を追って採血して得た血漿中のEGCG濃度を測定し、台形法により曲線下面積(AUC)に変換してEGCGの血中滞留量を比較した。
<Test Example 1>
First, 3 lots of Benifuuki extract (Benifuki tea hot water extract from Asahi Beverage Co., Ltd .; lot 1 [i], lot 2 [ii], lot 3 [iii]), and 2 lots are usually used as food ingredients Of green tea extract (hereinafter referred to as “green tea extract”) (green tea hot water extract from Saneigen FFI Corporation; lot 4 [iv], lot 5 [v]) did. Specifically, each administration solution prepared to have an EGCG concentration of 1 mM was administered to rats by single oral gavage, and the EGCG concentration in plasma obtained by collecting blood over time after administration was measured. The amount of EGCG staying in the blood was compared by converting the area under the curve (AUC) by the trapezoidal method.

更に詳細な実験操作法を説明すれば、以下のとおりである。   A more detailed experimental operation method will be described as follows.

実験に使用したラット(Sprague Dawley、雄、8週齢;日本SLC株式会社製)は、前もって頸静脈からカニューレを心臓方向に挿入し、カニューレ先端の開口部が右心房の入口近傍に位置するよう留置手術を行った後、実験開始までに1週間の回復期間をおいた。回復期間中のラットは、床網を備えたケージ中で個別に飼育し、CE-2飼料(日本クレア株式会社製)を自由摂食させた。各投与液についての被験数としては、[i]べにふうきエキスのロット1及び[ii]ロット2投与群はそれぞれn = 7、[iii]べにふうきエキスのロット3投与群はn = 6、[iv]「緑茶エキス」のロット4投与群はn = 5、[v]「緑茶エキス」のロット5投与群はn = 4、とした。   Rats used in the experiment (Sprague Dawley, male, 8 weeks old; manufactured by SLC Japan) inserted the cannula from the jugular vein in the direction of the heart in advance, so that the opening at the tip of the cannula was located near the entrance of the right atrium After indwelling surgery, a one-week recovery period was allowed before the start of the experiment. Rats during the recovery period were individually housed in cages equipped with a floor net and freely fed with CE-2 feed (manufactured by CLEA Japan, Inc.). The number of tests for each administration solution was [i] Benifuuki extract lot 1 and [ii] lot 2 administration group, n = 7, and [iii] Benifuuki extract lot 3 administration group, n = 6, [iv] The lot 4 administration group of “green tea extract” was n = 5, and the lot 5 administration group of “v” “green tea extract” was n = 4.

実験前日の夕方から、16時間絶食させたラットに体重100 g 当たり1 mLの上記投与液[i]〜[v]を単回強制経口投与した。投与前、投与後0.25、0.5、1、2、3時間の時点で各ラットからカニューレを通して0.5 mLずつヘパリン採血し、採血直後に血漿を分離して分析時まで酸性下で-80℃に保存した。   From the evening of the day before the experiment, 1 mL of the above-mentioned administration liquids [i] to [v] per 100 g body weight were administered by single oral gavage to rats fasted for 16 hours. Before administration and at 0.25, 0.5, 1, 2, and 3 hours after administration, 0.5 mL of heparin was collected from each rat through a cannula, and immediately after blood collection, plasma was separated and stored at -80 ° C under acidic conditions until analysis. .

血漿中のEGCG濃度は、各血漿を酸性下において酢酸エチル抽出・乾固した後、HPLCの移動相溶液に溶解してHPLC分析(電気化学検出法)することにより測定した。HPLCによるEGCGの分離は、HPLC装置(SCL-10Avp; 株式会社島津製作所製)に2.0 mm×150 mm(粒子径5μm) の逆相系カラム (CAPCELL PAKC18 MGII;株式会社資生堂製) を装着し、カラム温度40℃にて実施した。カラムへのサンプルのインジェクション量は20μL、移動相には0.1 mMのEDTA・2Naを含む0.1% リン酸:アセトニトリル = 90:10を用い、流速0.4 mL/minでアイソクラティック溶出した。EGCGの検出は、電気化学検出器(NANOSPACESI-2; 株式会社資生堂製)により行い、600 mVの印加電圧で検出された電流値の溶出パターンからピーク面積を算出し、濃度既知のEGCG標準物質のピーク面積から作成した標準直線を用いて定量した。EGCG標準物質の保持時間は8.0分、検出感度は2 nMであった。実際の投与液についてもEGCGの含有濃度を再度分析し、予定通りのEGCG量がラットへ投与されたことを確認した。ここで、血漿中のEGCG濃度を、β-グルクロニダーゼおよびスルファターゼにより脱抱合処理する前と後で測定した結果、脱抱合処理の前後でEGCG濃度に変化はなく、EGCGは血中において大部分が未抱合の遊離体として存在するものと考えられた。このことより、以下に示す結果は全て、脱抱合処理を行わなかった場合の測定結果である。   The EGCG concentration in plasma was measured by extracting each plasma from ethyl acetate under acidic conditions and drying it, and then dissolving it in an HPLC mobile phase solution and performing HPLC analysis (electrochemical detection method). For separation of EGCG by HPLC, a 2.0 mm x 150 mm (particle size 5 μm) reversed phase column (CAPCELL PAKC18 MGII; manufactured by Shiseido Co., Ltd.) is installed in an HPLC device (SCL-10Avp; manufactured by Shimadzu Corporation) The column temperature was 40 ° C. The amount of sample injected into the column was 20 μL, and 0.1% phosphoric acid: acetonitrile = 90: 10 containing 0.1 mM EDTA · 2Na was used as the mobile phase, and isocratic elution was performed at a flow rate of 0.4 mL / min. EGCG is detected using an electrochemical detector (NANOSPACESI-2; manufactured by Shiseido Co., Ltd.). The peak area is calculated from the elution pattern of the current value detected at an applied voltage of 600 mV. It quantified using the standard straight line created from the peak area. The retention time of the EGCG standard was 8.0 minutes and the detection sensitivity was 2 nM. Regarding the actual administration solution, the content of EGCG was analyzed again to confirm that the expected amount of EGCG was administered to the rats. Here, EGCG concentration in plasma was measured before and after deconjugation treatment with β-glucuronidase and sulfatase, and as a result, there was no change in EGCG concentration before and after deconjugation treatment. It was thought to exist as a free form of conjugation. From this, all the results shown below are measurement results when the deconjugation treatment was not performed.

図1には、各投与液を投与後3時間までのラット血漿中EGCG濃度(mean±SEM)の経時変化を示す。また、図2には、血漿中EGCG濃度×時間(曲線下面積)(mean±SEM)の経時変化を示す。これらの結果について以下のように統計解析を行った。   FIG. 1 shows changes with time in the EGCG concentration (mean ± SEM) in rat plasma up to 3 hours after administration of each administration solution. Further, FIG. 2 shows the time-dependent change in plasma EGCG concentration × time (area under the curve) (mean ± SEM). These results were statistically analyzed as follows.

各投与液をラットに投与した後の3時間までの血漿中EGCG濃度×時間(曲線下面積)および投与後の経過時間を因子とした、繰り返しのある二元配置の分散分析法による多重比較検定(FisherのPLSD法;危険率5%)を実施した。その結果を表1に示す。   Multiple comparison test using repeated two-way ANOVA with factors of plasma EGCG concentration up to 3 hours x time (area under the curve) and elapsed time after administration of each dose to rats (Fisher's PLSD method; risk rate 5%). The results are shown in Table 1.

Figure 2010011751

表1に示すように、多重比較検定の結果、べにふうきエキス[i]とべにふうきエキス[ii]の間、およびべにふうきエキス[i]とべにふうきエキス[iii]の間には、血漿中EGCG濃度の曲線下面積に有意差が認められ、べにふうきエキス同士の間でもロットの違いによって血中のEGCG滞留量に差を生じることが示された。しかし、べにふうきエキス[i]、べにふうきエキス[ii]、べにふうきエキス[iii]のいずれを投与した場合にも、「緑茶エキス」[iv]あるいは「緑茶エキス」[v]を投与したときに比べて、血漿中EGCG濃度の曲線下面積は有意に高いことが示された。即ち、EGCGの含有量が同一であるべにふうきエキスおよび「緑茶エキス」を投与したにもかかわらず、血液中のEGCG滞在量は、べにふうきエキスを投与した場合の方が「緑茶エキス」を投与した場合よりも有意に高くなることが示された。投与後3時間までの曲線下面積で比較したとき、べにふうきエキス[i]、べにふうきエキス[ii]、およびべにふうきエキス[iii]投与によるEGCGの血中滞留量は、「緑茶エキス」[iv]と比較してそれぞれ5.3倍、4.4倍、および3.7倍であり、「緑茶エキス」[v]との比較ではそれぞれ4.8倍、4.0倍、および3.4倍であった。   As shown in Table 1, as a result of the multiple comparison test, the plasma EGCG concentration curve between Benifuuki extract [i] and Benifuuki extract [ii] and between Benifuuki extract [i] and Benifuuki extract [iii] Significant differences were observed in the lower area, and it was shown that EGCG retention in the blood was also different depending on the lot between Benifuuki extracts. However, when the Benifuuki extract [i], Benifuuki extract [ii], or Benifuuki extract [iii] is administered, the “green tea extract” [iv] or the “green tea extract” [v] is administered. The area under the curve of plasma EGCG concentration was shown to be significantly higher. In other words, despite the administration of Benifuuki extract and “Green tea extract” with the same EGCG content, the amount of EGCG staying in the blood is the same when the Benifuuki extract is administered and the “Green tea extract” is administered. It was shown to be significantly higher than. When compared with the area under the curve for up to 3 hours after administration, the amount of EGCG retained in the blood by administration of Benifuuki extract [i], Benifuuki extract [ii], and Benifuuki extract [iii] was “Green tea extract” [iv]. They were 5.3 times, 4.4 times, and 3.7 times, respectively, and 4.8 times, 4.0 times, and 3.4 times, respectively, in comparison with “Green tea extract” [v].

これらの結果から、べにふうきエキスが、ロットの違いによって多少の高低はあるものの、普遍的に通常の緑茶エキスより高いEGCG吸収性を有することが明らかとなった。   From these results, it was clarified that the Benifuuki extract has a higher EGCG absorbability than the normal green tea extract, although there are some differences depending on the lot.

<試験例2>
試験例1によって、べにふうきエキスは一般的に、通常の緑茶エキスに比べてEGCGの吸収性において優れていることが示された。べにふうきエキスも通常の緑茶エキスも、両者共に同様の熱水抽出操作によって得られたエキスであるにもかかわらず、EGCGの吸収性に大きな差が生じる原因は、抽出されたエキス中に含まれる物質に違いがあるためと考えられた。即ち、緑茶エキス中にEGCGの吸収を阻害する成分が存在する可能性や、べにふうきエキス中にEGCGの吸収を促進する成分が存在する可能性などが考えられた。そこで、これらの可能性を追究するための糸口をつかむことを目的として、本試験例に示す実験を行った。即ち、含有するEGCGの濃度が互いに等しいべにふうきエキス溶液、通常の緑茶エキス溶液、ならびにEGCG試薬溶液を調製し、これらの溶液を適宜組み合わせて混合した溶液をラットへ投与した場合に、EGCGの吸収性がどのように変化するかを調べた。
<Test Example 2>
Test Example 1 showed that the Benifuuki extract is generally superior in EGCG absorbability compared to a normal green tea extract. Despite the fact that both Benifuuki extract and regular green tea extract are obtained by the same hot water extraction procedure, the cause of the large difference in EGCG absorbability is the substance contained in the extracted extract. It was thought that there was a difference. That is, the possibility that a component that inhibits the absorption of EGCG exists in the green tea extract and the possibility that a component that promotes the absorption of EGCG exists in the Benifuuki extract were considered. Therefore, an experiment shown in this test example was conducted for the purpose of grasping clues for pursuing these possibilities. In other words, when the EGCG solution containing the same concentration of EGCG is prepared, a normal green tea extract solution and an EGCG reagent solution are prepared, and these solutions are combined in an appropriate combination and administered to rats. To see how changes occur.

更に詳細な実験操作法を説明すれば、以下のとおりである。   A more detailed experimental operation method will be described as follows.

3種類の投与液、即ち、[i]EGCG試薬(Sigma社製;Cat. No. E4143)の1 mM溶液、[ii]EGCG試薬と「緑茶エキス」の混合溶液([1 mM EGCG試薬溶液]:[EGCG濃度が1 mMとなるよう調製した「緑茶エキス」溶液]=1:1 (v/v) の混合溶液)、[iii]べにふうきエキスと「緑茶エキス」の混合溶液([EGCG濃度が1 mMとなるよう調製したべにふうきエキス溶液]:[EGCG濃度が1 mMとなるよう調製した「緑茶エキス」溶液]=1:1 (v/v) の混合溶液)を準備した。従って、いずれの投与液も含有するEGCGの濃度は1 mMである。なお、本試験例の実験に使用したべにふうきエキスは、試験例1において用いられたアサヒ飲料株式会社製のべにふうき茶熱水抽出物のロット1であり、また、「緑茶エキス」は、試験例1において用いられた三栄源エフエフアイ株式会社製の緑茶熱水抽出物のロット4である。   Three types of administration solutions, namely [i] EGCG reagent (Sigma; Cat. No. E4143) 1 mM solution, [ii] EGCG reagent and “green tea extract” mixed solution ([1 mM EGCG reagent solution] : [Green tea extract solution prepared to an EGCG concentration of 1 mM] = 1: 1 (v / v) mixed solution), [iii] Benifuuki extract and green tea extract mixed solution ([EGCG concentration is BENFUKI EXTRACT SOLUTION PREPARED TO 1 mM]: ["Green Tea Extract" Solution Prepared to EGCG Concentration of 1 mM] = 1: 1 (v / v) Mixed Solution). Therefore, the concentration of EGCG containing any of the administration solutions is 1 mM. The Benifuuki extract used in the experiment of this test example is lot 1 of Benifuuki tea hot water extract manufactured by Asahi Beverage Co., Ltd. used in Test Example 1, and “Green tea extract” is Test Example 1. It is lot 4 of the green tea hot water extract made by San-Ei Gen FFI Co., Ltd. used in the above.

試験例1と同様の方法により、それぞれの投与液を静脈にカニューレを装着したラットへ強制経口投与し、投与後の時間経過を追って血漿中のEGCG濃度を測定し、曲線下面積に変換してEGCGの血中滞留量を比較した。なお、各投与液についての被験数としては、 [i]EGCG試薬溶液投与群はn = 8、[ii]EGCG試薬と「緑茶エキス」の混合溶液投与群はn = 7、[iii]べにふうきエキスと「緑茶エキス」の混合溶液投与群はn = 6、とした。   In the same manner as in Test Example 1, each solution was forcibly orally administered to a rat with a cannula attached to a vein, the EGCG concentration in plasma was measured over time after administration, and converted to the area under the curve. EGCG blood retention was compared. In addition, the number of tests for each administration liquid was as follows: [i] EGCG reagent solution administration group, n = 8, [ii] EGCG reagent and “green tea extract” mixed solution administration group, n = 7, [iii] Benifuuki extract And n = 6 in the mixed solution administration group of “green tea extract”.

図3には、各投与液を投与後3時間までのラット血漿中EGCG濃度(mean±SEM)の経時変化を示す。また、図4には、血漿中EGCG濃度×時間(曲線下面積)(mean±SEM)の経時変化を示す。これらの結果について以下のように統計解析を行った。   FIG. 3 shows time-dependent changes in EGCG concentration (mean ± SEM) in rat plasma up to 3 hours after administration of each administration solution. FIG. 4 shows the time-dependent change in plasma EGCG concentration × time (area under the curve) (mean ± SEM). These results were statistically analyzed as follows.

各投与液をラットに投与した後の3時間までの血漿中EGCG濃度×時間(曲線下面積)および投与後の経過時間を因子とした、繰り返しのある二元配置の分散分析法による多重比較検定(FisherのPLSD法;危険率5%)を実施した。その結果を表2に示す。   Multiple comparison test using repeated two-way ANOVA with factors of plasma EGCG concentration up to 3 hours x time (area under the curve) and elapsed time after administration of each dose to rats (Fisher's PLSD method; risk rate 5%). The results are shown in Table 2.

Figure 2010011751
Figure 2010011751

表2に示すように、多重比較検定の結果、EGCG試薬と「緑茶エキス」の混合溶液をラットに投与したとき、EGCG試薬のみの溶液を投与したときに比べて血漿中EGCG濃度の曲線下面積は有意に減少し、EGCG試薬に「緑茶エキス」を添加することによりEGCGの血中滞留量が少なくなることが示された。即ち、「緑茶エキス」に含まれる何らかの成分がEGCGの吸収を抑制するものと推測された。これに対して、「緑茶エキス」にEGCG試薬を混合する代わりにべにふうきエキスを混合してラットに投与すると、血漿中EGCG濃度の曲線下面積はEGCG試薬溶液を投与したときと同等のレベルにまで回復し、「緑茶エキス」にEGCG試薬を混合したときと比べて有意に高くなった。このことは、「緑茶エキス」にべにふうきエキスを混合することにより、「緑茶エキス」中の成分によるEGCGの吸収阻害効果を打ち消してEGCGの吸収量が増加し、結果的に血中滞留量が増加したことを示唆していた。   As shown in Table 2, as a result of the multiple comparison test, when the mixed solution of EGCG reagent and “green tea extract” was administered to rats, the area under the curve of the plasma EGCG concentration compared to when the EGCG reagent-only solution was administered Was significantly decreased, and it was shown that the amount of EGCG retained in the blood decreased by adding “green tea extract” to the EGCG reagent. That is, it was speculated that some component contained in “green tea extract” suppresses absorption of EGCG. On the other hand, instead of mixing EGCG reagent with `` Green tea extract '', benifuuki extract was mixed and administered to rats, and the area under the curve of plasma EGCG concentration reached the same level as when EGCG reagent solution was administered. It recovered and became significantly higher than when the EGCG reagent was mixed with the “green tea extract”. This is because mixing the “green tea extract” with the Benifuuki extract counteracts the EGCG absorption-inhibiting effect of the ingredients in the “green tea extract” and increases the amount of EGCG absorbed, resulting in an increase in blood retention. It was suggested that.

「緑茶エキス」にべにふうきエキスを添加して得られるEGCGの血中滞留量増加の度合いは、投与後3時間までの曲線下面積で比較したとき、「緑茶エキス」にEGCG試薬を添加した場合の1.6倍であった。   The degree of increase in blood retention of EGCG obtained by adding Befufuuki extract to `` Green tea extract '' is compared with the area under the curve up to 3 hours after administration when EGCG reagent is added to `` Green tea extract '' It was 1.6 times.

これらの結果から、緑茶エキス自体に付随した吸収阻害効果を打ち消す効果はべにふうきエキスに特有の効果であり、EGCGの吸収性が低い緑茶エキスにべにふうきエキスを添加することによって、緑茶エキスからのEGCG吸収性が高められることが明らかとなった。   From these results, the effect of counteracting the absorption inhibition effect associated with the green tea extract itself is an effect unique to Benifuuki extract, and by adding the Benifuuki extract to the green tea extract with low EGCG absorption, EGCG absorption from the green tea extract It became clear that the sex was improved.
