【発明の属する技術分野】
本発明は、バルバロインを含有する組成物およびその製造法に関するものである。
【0002】
【従来の技術】
バルバロインは下記化1の構造を有するアンスロン配糖体の一種であって、緩下作用を有することが確認されている。
【0003】
【化1】
【0004】
バルバロインは天然にはユリ科アロエ属植物の多くに含まれており(たとえばAloe ferox,Aloe africana,Aloe spicata,Aloe arborescens等)、これらバルバロインを含有するアロエの搾汁液またはその濃縮乾燥物を医薬品ないしは民間療法薬として利用することが小規模で行われている。しかしながら、アロエから分離されたバルバロインは水溶液状態では非常に不安定であるから、バルバロインの上記薬理作用を期待するならばできるだけ新鮮な搾汁液を利用する必要がある。また、保存可能な医薬品とするには液剤は無理で、固形のものとする必要があった。いうまでもなく、日常的に摂取容易な飲料の形にして提供することも不可能であった。
【0005】
バルバロインが水溶液状態でなぜ不安定なのかは確認されておらず、バルバロインの水中での安定性を向上させる方法も知られていなかった。
【0006】
【発明が解決しようとする課題】
本発明の目的は、バルバロインを水溶液状態でも安定に保つ手段を見いだし、バルバロインをアロエ等から抽出して利用するときの利用効率を高めることにある。
【0007】
本発明の他の目的は、水溶液にしても安定なバルバロインを含有する組成物を提供し、バルバロインの薬理作用の利用を容易にすることにある。
【0008】
本発明のさらに他の目的は、長期間安定なバルバロインを含有する飲料を提供し、バルバロインの日常的な摂取を容易にすることにある。
【0009】
【課題を解決するための手段】
上記目的を達成することに成功した本発明は、概略、次の各発明からなる。
(1)バルバロインを含有するアロエの含水エタノール抽出液またはその濃縮液と、L-アスコルビン酸とを含有させてなり、飲料中のバルバロイン濃度が0.0020〜0.050重量%であり、L-アスコルビン酸濃度が0.2〜0.5重量%である飲料。
【0012】
(2)バルバロインを含有するアロエを含水エタノールで抽出処理し、得られた抽出液またはその濃縮液にL-アスコルビン酸を混合することを特徴とする上記(1)記載の飲料の製造法。
【0013】
(3)L-アスコルビン酸を添加した含水エタノールを用いてバルバロインを含有するアロエを抽出処理し、得られた抽出液を濃縮または乾燥することを特徴とする上記(1)記載の飲料の製造法。
【0014】
すなわち、本発明は水溶液状態のバルバロインがアスコルビン酸類によって顕著に安定化されるという、本発明者らによる新規な知見に基づくものである。
【0015】
【発明の実施の形態】
本発明で用いるバルバロインとしては、バルバロインを含有するアロエの葉部その他の地上部より搾汁、浸出、抽出等の操作で得られた汁液または抽出液、およびそれらの濃縮物、精製物等を利用することができる。よく知られているように、アロエはバルバロイン以外にも有用成分を多数含有し、健康飲料の原料として利用されることが多いものであるから、用途によっては(たとえば飲料とする場合には)、バルバロインを低濃度で含有するアロエ抽出物をそのまま本発明の組成物(具体的には飲料等)に使用することができる。
【0016】
バルバロイン抽出原料のアロエは、生鮮物でも乾燥物でもよい。バルバロインはアロエの細胞中にある間は安定であるが、そこから溶出した直後から、それを分解もしくは不活性化する何らかの作用を受けるものと思われる。したがって、バルバロインを抽出する操作は、抽出中もバルバロインをなるべく変化させないものであることが望ましい。種々検討の結果、含水エタノールによる抽出は、搾汁や浸出による場合よりも、また熱水抽出による場合よりも、バルバロインの損失が少なく、好ましいことがわかった。
【0017】
抽出に用いる含水エタノールとしては、エタノール濃度20〜95vol%程度のものが適当である。抽出は、常温ないし還流加熱下に行うことができる。
得られた抽出液を、製品の用途に応じて適当な固形分濃度まで濃縮し、さらに必要に応じて乾燥する。
【0018】
ここまでの任意の段階で、抽出されたバルバロインにアスコルビン酸類を混合し、バルバロインを安定化する。すなわち、
▲1▼ 抽出操作の段階で、抽出溶媒にアスコルビン酸類を添加しておく。
▲2▼ 得られた抽出液に、直ちにアスコルビン酸類を添加する。
▲3▼ 抽出液の濃縮物または乾燥物にアスコルビン酸類を混合する。
などにより、アスコルビン酸類をバルバロインと共存させ、本発明の組成物を得る。
【0019】
添加するアスコルビン酸類としては、ビタミンCとして広く利用されているアスコルビン酸が最も好ましい。アスコルビン酸含有率の高い果汁濃縮物、たとえばアセロラ・ローズヒップ、刺梨、柑橘類等の果汁の濃縮物をアスコルビン酸に代えて用いることもできる。本発明ではL-アスコルビン酸を用いる。
【0020】
アスコルビン酸類によるバルバロインの安定化は、バルバロイン濃度のいかんにかかわらずバルバロインが溶存する系中に微量でも(たとえば0.2重量%程度;後記実施例3参照)アスコルビン酸類が存在すれば達成される。しかしながら、飲料等に配合された場合、アスコルビン酸類もまた酸素、熱、光等の影響を受けて徐々に分解するので、組成物の用途や期待される保存可能期間に応じて、過剰量のアスコルビン酸類を配合しておくことが望ましい。
【0021】
バルバロインは、抽出液濃縮物中にある状態においても本質的に不安定である。アスコルビン酸類はそれを安定化するが、そこにエタノールが共存するとバルバロインは一層安定になる。したがって、濃縮中にエタノールが蒸発して水溶液の状態になっている濃縮物に少量のエタノールを加えて含水エタノール溶液の状態にすることは、バルバロインの安定性向上のために好ましい。
【0022】
上述のようにして得られる本発明のバルバロイン含有組成物は、水溶液(抽出液から濃縮物まで)の状態でもバルバロインが変化するおそれなしに保存が可能である(乾燥物にしたものは、その状態ではアスコルビン酸類の安定化作用を期待するまでもなくバルバロインは安定であるが、水溶液にしたときアスコルビン酸類によるバルバロイン安定化作用が発現する。)。バルバロインと共存する成分がバルバロイン以外のアロエ成分とアスコルビン酸類であっていずれも無害なものであるから、液剤、ドリンク剤、チンキ剤等の形態の医薬品やいわゆる健康食品の分野においてバルバロインを利用しようとするとき、バルバロインを単離しなくてもそのまま原料として使用することができる。
【0023】
バルバロインを含有する本発明の組成物は、バルバロインを含有させた飲料の製造原料とする。すなわち、上記本発明の組成物を任意の組成の飲料の製造工程の任意の段階で溶解するだけで、アスコルビン酸類により安定化されたバルバロインを含有する飲料となる。バルバロインと共に飲料中に入るアスコルビン酸類は、ビタミンCとして、あるいは酸味料として、多くの飲料に添加されている成分であるから、何ら不都合がないだけでなく有効に利用されることになる。
【0024】
いうまでもなく、バルバロインを含有するアロエ抽出液またはその濃縮物とアスコルビン酸類とを別々に(すなわち上記本発明の組成物を経由することなく)飲料製造工程において添加しても、飲料中のバルバロインのアスコルビン酸類による安定化は達成される。
【0025】
飲料中のバルバロインの濃度は特に制限されるものではないが、約0.05重量%以下にすることが望ましい。それ以上高濃度で含有させると、アスコルビン酸類による安定化が困難になるわけではないが溶解状態が不安定になり、沈殿物を生じやすい。
【0026】
本発明によりバルバロインを安定に含有させることができる飲料の具体例としては、各種清涼飲料(いわゆる栄養飲料、スポーツ飲料等を含む)、果実飲料、野菜ジュース、乳飲料等がある。
【0027】
アロエ抽出液や本発明の組成物に含まれるバルバロインは、高速液体クロマトグラフィーにより定量することができる。この明細書中に記載したバルバロインの定量値は下記の測定条件によるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a composition containing barbaroin and a method for producing the same.
[0002]
[Prior art]
Barbaroin is a kind of anthrone glycoside having the structure of Chemical Formula 1 below, and has been confirmed to have a laxative action.
[0003]
[Chemical 1]
[0004]
Barbaroin is naturally contained in many species of the genus Aloe family (for example, Aloe ferox, Aloe africana, Aloe spicata, Aloe arborescens, etc.). Aloe squeezed juice containing these barbaroins or concentrated dried product thereof is used. It is used on a small scale as a medicine or folk remedy. However, since barbaroin separated from aloe is very unstable in an aqueous solution state, it is necessary to use a freshly squeezed juice as much as possible if the above pharmacological action of barbaroin is expected. In addition, in order to make a storable pharmaceutical product, the liquid preparation is impossible, and it is necessary to make it solid. Needless to say, it has not been possible to provide it in the form of a drink that can be easily taken on a daily basis.
[0005]
The reason why barbaroin is unstable in an aqueous solution has not been confirmed, and a method for improving the stability of barbaroin in water has not been known.
[0006]
[Problems to be solved by the invention]
An object of the present invention is to find a means for keeping barbaroin stable even in an aqueous solution, and to improve the utilization efficiency when barbaroin is extracted from aloe or the like and used.
[0007]
Another object of the present invention is to provide a composition containing barbaroin that is stable even in an aqueous solution, and to facilitate the utilization of the pharmacological action of barbaroin.
[0008]
Still another object of the present invention is to provide a beverage containing barbaroin that is stable for a long period of time and to facilitate daily intake of barbaroin.
[0009]
[Means for Solving the Problems]
The present invention which has succeeded in achieving the above object is roughly composed of the following inventions.
(1) An aloe hydrous ethanol extract containing barbaroin or a concentrated solution thereof, and L-ascorbic acid are contained, and the barbaroin concentration in the beverage is 0.0020 to 0.050% by weight, A beverage having an L-ascorbic acid concentration of 0.2 to 0.5% by weight.
[0012]
(2) The method for producing a beverage according to the above (1), wherein the aloe containing barbaroin is extracted with water-containing ethanol, and L-ascorbic acid is mixed with the obtained extract or its concentrated solution.
[0013]
(3) The beverage according to (1) above, wherein the aloe containing barbaroin is extracted using hydrous ethanol to which L-ascorbic acid has been added, and the resulting extract is concentrated or dried. Law.
[0014]
That is, the present invention is based on a novel finding by the present inventors that barbaroin in an aqueous solution state is significantly stabilized by ascorbic acids.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
As barbaroin used in the present invention, the juice or extract obtained by operations such as squeezing, leaching, extraction from the aloe leaf part or other above-ground parts containing barbaroin, and their concentrates, purified products, etc. Can be used. As is well known, aloe contains many useful ingredients in addition to barbaroin, and is often used as a raw material for health drinks. An aloe extract containing barbaroin at a low concentration can be used as it is in the composition of the present invention (specifically, a beverage or the like).
[0016]
The aloe as the raw material for barbaroin extraction may be fresh or dried. Barbaroin is stable while in aloe cells, but appears to undergo some action to degrade or inactivate it immediately after elution. Therefore, it is desirable that the operation for extracting the barbaroin is one that does not change the barbaroin as much as possible during the extraction. As a result of various studies, it has been found that extraction with hydrous ethanol is preferable because it has less loss of barbaroin than by squeezing or leaching, and also by hot water extraction.
[0017]
As the water-containing ethanol used for extraction, one having an ethanol concentration of about 20 to 95 vol% is suitable. The extraction can be performed at room temperature or under reflux.
The obtained extract is concentrated to an appropriate solid concentration according to the use of the product, and further dried as necessary.
[0018]
At any stage so far, ascorbic acids are mixed with the extracted barbaroin to stabilize the barbaroin. That is,
(1) Ascorbic acids are added to the extraction solvent at the stage of the extraction operation.
(2) Ascorbic acids are immediately added to the obtained extract.
(3) Ascorbic acid is mixed with the concentrate or dried product of the extract.
Ascorbic acids are allowed to coexist with barbaroin to obtain the composition of the present invention.
[0019]
As ascorbic acid to be added, ascorbic acid widely used as vitamin C is most preferable. A fruit juice concentrate having a high ascorbic acid content, for example, a fruit juice concentrate such as acerola rosehip, sashimi, and citrus can be used in place of ascorbic acid. In the present invention, L-ascorbic acid is used.
[0020]
Stabilization of barbaroin by ascorbic acids is achieved in the presence of ascorbic acid even in a trace amount (for example, about 0.2% by weight; see Example 3 below) in a system in which barbaroin is dissolved regardless of the barbaroin concentration. Is done. However, when incorporated in beverages, etc., ascorbic acids also gradually decompose under the influence of oxygen, heat, light, etc., so an excessive amount of ascorbine depends on the use of the composition and the expected shelf life. It is desirable to mix acids.
[0021]
Barbaroin is inherently unstable even at certain conditions in the extract concentrate. Ascorbic acid stabilizes it, but when ethanol coexists there, barbaroin becomes more stable. Therefore, it is preferable to add a small amount of ethanol to the concentrate in the form of an aqueous solution due to evaporation of ethanol during the concentration to obtain a water-containing ethanol solution in order to improve the stability of barbaroin.
[0022]
The barbaroin-containing composition of the present invention obtained as described above can be stored without fear that the barbaroin will change even in the state of an aqueous solution (from the extract to the concentrate). In that state, barbaroin is stable without expecting the stabilizing action of ascorbic acids, but when it is made into an aqueous solution, the barbaroin stabilizing action by ascorbic acids is expressed.) The ingredients that coexist with barbaroin are aloe components other than barbaroin and ascorbic acids, both of which are harmless, so barbaroin is used in the field of pharmaceuticals in the form of liquids, drinks, tinctures, and so-called health foods. When trying to use it, it can be used as a raw material as it is without isolating barbaroin.
[0023]
The composition of the present invention containing barbaroin is used as a raw material for producing a beverage containing barbaroin. That is, the beverage of the present invention can be obtained by simply dissolving the composition of the present invention at any stage of the production process of a beverage having any composition, and thus containing a barbaroin stabilized by ascorbic acids. Ascorbic acids that enter the beverage together with barbaroin are components added to many beverages as vitamin C or as a sour agent, so that they are not only inconvenient but also effectively used.
[0024]
Needless to say, even if the aloe extract containing barbaroin or its concentrate and ascorbic acids are added separately (that is, without going through the composition of the present invention) in the beverage production process, Stabilization of barbaroin with ascorbic acids is achieved.
[0025]
The concentration of barbaroin in the beverage is not particularly limited, but is preferably about 0.05% by weight or less. If it is contained at a higher concentration than that, stabilization with ascorbic acids is not difficult, but the dissolved state becomes unstable and precipitates are likely to occur.
[0026]
Specific examples of beverages that can stably contain barbaroin according to the present invention include various soft drinks (including so-called nutritional drinks and sports drinks), fruit drinks, vegetable juices, milk drinks, and the like.
[0027]
Barbaroin contained in the aloe extract or the composition of the present invention can be quantified by high performance liquid chromatography. The quantitative value of barbaroin described in this specification is based on the following measurement conditions.

【Example】
Aloe extract production example 1
10 kg of 30% ethanol was added to 1 kg of dried Kidachi aloe leaves, and the mixture was heated and extracted for 1 hour under reflux. After cooling, the extract obtained by filtration was concentrated to 4 kg under reduced pressure. 1 liter of ethanol was added to the resulting concentrated solution, and the resulting insoluble matter was removed by filtration, followed by concentration to 800 ml under reduced pressure, and finally 200 ml of ethanol was added. The obtained aloe extract contained 0.2% by weight of barbaroin.
Aloe extract production example 2
10 liters of 50% ethanol was added to 500 g of dried cape aloe leaves, and the mixture was heated and extracted for 1 hour under reflux. After cooling, the extract obtained by filtration was concentrated to 2 kg under reduced pressure. Ethanol (500 ml) was added to the resulting concentrated liquid, and the resulting insoluble matter was filtered off. The filtrate was concentrated to 200 ml under reduced pressure, and finally 50 ml of ethanol was added. The obtained aloe extract contained 0.3% by weight of barbaroin.
