Description

本発明は、血糖値改善作用を有するアイセンハルドチア(Eysenhardtia)属植物からの溶媒抽出物および/またはその処理物を含有する糖尿病疾患の予防改善用である、食品または飲料、もしくは経口投与される医薬品に関する。 The present invention is a food or beverage or orally administered for the prevention and improvement of a diabetic disease containing a solvent extract from a plant of the genus Eisenhardtia having a blood glucose level improving action and / or a processed product thereof. Regarding pharmaceuticals.

近年では、欧米風の生活様式や高カロリー食物の摂取が一般化し、これに伴う生活習慣病が問題となっている。また、カロリーの高い食生活は、肥満を引き起こしやすく、肥満は様々な生活習慣病を引き起こすともいわれている。特に肥満になると、糖尿病の診断基準に達しないまでも、発症する危険性の高い、耐糖能に異常を有する状態となる可能性が高いとされている。糖尿病は、その患者数は現在も増加の一途を辿り、2025年には全世界で3億人に到達するといわれている。また、わが国に於いても近年空腹時血糖値の基準等を見直す動きがあり、糖尿病の前段階にあると規定される層の人数の大幅な増加が予想される。 In recent years, Western-style lifestyles and high-calorie food intake have become common, and lifestyle-related diseases associated therewith have become a problem. In addition, a diet high in calories is likely to cause obesity, which is said to cause various lifestyle-related diseases. In particular, when it becomes obese, it is said that there is a high possibility of developing an abnormality in glucose tolerance even if it does not reach the diagnostic criteria for diabetes. Diabetes is said to continue to increase in number of patients, reaching 300 million worldwide by 2025. In recent years, there has been a movement to review the fasting blood glucose level standards in Japan, and a significant increase in the number of people defined as being in the pre-stage of diabetes is expected.

このような糖尿病患者数およびその前段階層の増加に対して、発症予防、特に一次予防の重要性が指摘されている。糖尿病の発症は、生活習慣とりわけ食習慣に起因することから、日常の食生活において糖尿病の発症を予防することが重要である。 The importance of prevention of onset, particularly primary prevention, has been pointed out against the increase in the number of diabetic patients and their predecessors. Since the onset of diabetes is caused by lifestyle habits, particularly eating habits, it is important to prevent the onset of diabetes in daily eating habits.

糖尿病の発症を効率良く予防するには、血糖値の急激な上昇をコントロールすることが不可欠であり、そのような糖尿病予防効果を有する、食経験があり安全性の問題のない天然物素材の開発が望まれる。 In order to effectively prevent the onset of diabetes, it is indispensable to control the rapid increase in blood sugar level, and the development of natural product materials that have such dietary experience and have no safety issues with such diabetes prevention effects. Is desired.

糖尿病予防効果を有する天然物素材としては、オオゴチョウ、トウアズキ、モクセンナ(特許文献1参照)、アセロラ(特許文献2参照)、枇杷種子(特許文献3参照)、桑葉(特許文献4参照)等が知られているが、アイセンハルドチア(Eysenhardtia)属植物の抽出物には、抗菌作用のあることは知られているものの(特許文献5参照)、血糖値上昇抑制作用があることは、全く知られていなかった。 Examples of natural product materials having a diabetes-preventing effect include giant goose, red bean, moxenna (see Patent Document 1), acerola (see Patent Document 2), strawberry seed (see Patent Document 3), mulberry leaves (see Patent Document 4), and the like. Although known, the extract of the plant of the genus Eysenhardtia is known to have an antibacterial action (see Patent Document 5), but it is completely known that it has an action to suppress an increase in blood glucose level. It was not done.

本発明に係るアイセンハルドチア(Eysenhardtia)属植物のうち学名アイセンハルドチア アデノスティリス(Eysenhardtia adenostylis、以下E. Adenostylisと記す)の植物は、中米の一部地域でタライ(Taray)と呼ばれているマメ科の低木であり、茎又は皮の部分を水に浸しておき、得られた青い汁を腎臓治療のために使用することが知られており、長く利用されてきたという食用摂取の実績がある。しかし、利用量はとりたてて多いというわけではなく、さらなる活用の余地がある。 Among the plants belonging to the genus Eisenhardtia according to the present invention, a plant of the scientific name Eisenhardtia adenostylis (hereinafter referred to as E. Adenostylis) is called Talay in a part of Central America. It is a leguminous shrub that is known to use the resulting blue juice for kidney treatment by soaking its stem or skin in water and has been used for a long time. There is a track record. However, the usage is not very large and there is room for further utilization.

E. Inhibitory effect on [alpha] -glucosidase activity in Adenostylis extract E. coli obtained in the above production example. The inhibitory effect on the digestive enzyme α-glucosidase activity of the Adenostylis extract was evaluated by enzyme activity measurement.

まず、シュクロース(最終濃度100mM)を含む56mMのマレイン酸緩衝液(pH6.0)に、最終濃度が0.89〜14.25mg/mlとなるように試料(調製例1で得られたE. Adenostylis抽出物(粉体)をマレイン酸緩衝液で57mg/mlに調整したもの)を添加し、37℃で2分間予備加温した。その後、Rat intenstinal acetone powder(SIGMA社製)から粗精製した粗酵素希釈液50μLを添加し、撹拌後、37℃で30分間の酵素反応を行った。酵素反応終了後、2M Tris−HCl(pH7.0)300μlを添加して反応を停止し、生成されたグルコースの量を、ヘキソキナーゼ法に基づき(ニットーボーメディカル株式会社製N−アッセイ Glu−UL ニットーボーを使用)定量した。一方、対照として、E. Adenostylis抽出物を添加しなかったほかは上記と同様にして、生成されたグルコースの量を定量した。 First, in a 56 mM maleate buffer solution (pH 6.0) containing sucrose (final concentration 100 mM), a sample (E obtained in Preparation Example 1 was prepared so that the final concentration was 0.89 to 14.25 mg / ml. Adenostylis extract (powder) adjusted to 57 mg / ml with maleate buffer) was added and pre-warmed at 37 ° C. for 2 minutes. Thereafter, 50 μL of a crude enzyme diluted solution roughly purified from Rat intensified acetone powder (manufactured by SIGMA) was added, and after stirring, an enzyme reaction was carried out at 37 ° C. for 30 minutes. After completion of the enzymatic reaction, the reaction was stopped by adding 300 μl of 2M Tris-HCl (pH 7.0), and the amount of glucose produced was determined based on the hexokinase method (N-assay Glu-UL Nittobo manufactured by Nitto Bo Medical Co., Ltd.). Use) Quantified. On the other hand, E. as a control. The amount of glucose produced was quantified in the same manner as described above except that no Adenostylis extract was added.

次に、対照(E. Adenostylis抽出物無添加)における生成グルコース量に対する、E. Adenostylis抽出物における生成グルコース量の割合を百分率で算出し、α-グルコシダーゼのシュクロース分解活性に対する抑制率とした。0.89〜14.25mg/mlの濃度におけるE. Adenostylis抽出物によるα-グルコシダーゼのシュクロース分解活性の抑制率を、図1に示す。図1において明らかなように、E. Adenostylis抽出物は、0.89〜14.25mg/mlの間の濃度で濃度に依存してα-グルコシダーゼ活性の阻害作用を示していた。尚、IC50(50%抑制する濃度)は3.93mg/mlであった。このことから、抽出物は、α-グルコシダーゼの活性に対し有意な阻害作用を有することが明らかとなった。 Next, the E. adenostyli extract was added to the amount of glucose produced in E. Adenostylis extract-free. The ratio of the amount of glucose produced in the Adenostylis extract was calculated as a percentage and used as the inhibition rate for the sucrose degradation activity of α-glucosidase. E. coli at a concentration of 0.89 to 14.25 mg / ml. The inhibition rate of the sucrose degradation activity of α-glucosidase by the Adenostylis extract is shown in FIG. As is apparent in FIG. The Adenostylis extract showed an inhibitory effect on α-glucosidase activity depending on the concentration at concentrations between 0.89 and 14.25 mg / ml. IC 50 (concentration to suppress 50%) was 3.93 mg / ml. This revealed that the extract has a significant inhibitory action on the activity of α-glucosidase.

E. Adenostylis抽出物の食後血糖値上昇抑制作用(糖負荷試験)
本発明で用いるE. Adenostylis抽出物の食後血糖値上昇抑制効果を、糖負荷試験(シュクロース負荷試験)により評価した。
E. Adenostyli extract suppresses postprandial blood glucose level rise (sugar tolerance test)
E. used in the present invention The postprandial blood glucose level increase inhibitory effect of the Adenostylis extract was evaluated by a glucose tolerance test (sucrose tolerance test).

シュクロース負荷試験は、被検動物としてWistar系雄性ラット(SPF,9週齢)を使用し、17時間の絶食後、尾静脈採血による空腹時血糖値を測定した。その後、E. Adenostylis抽出物(1g/kg)とシュクロース(1.5g/kg)を強制経口投与し、投与の30、60、120分後に尾静脈採血を行って血糖値を測定した。血糖値は、小型電極式血糖値測定機器アントセンスII(三共株式会社製)を用いて測定した。一方、対照として、E. Adenostylis抽出物を添加しなかったほかは上記と同様にして血糖値を測定した。シュクロース負荷試験における血糖値の経時的変化を図2に示す。 In the sucrose load test, Wistar male rats (SPF, 9 weeks old) were used as test animals, and fasting blood glucose levels were measured by blood sampling from the tail vein after fasting for 17 hours. Thereafter, E.E. Adenostylis extract (1 g / kg) and sucrose (1.5 g / kg) were forcibly administered orally, and tail vein blood was collected 30, 60, and 120 minutes after administration to measure the blood glucose level. The blood glucose level was measured using a small electrode blood glucose level measuring instrument Antsense II (manufactured by Sankyo Corporation). On the other hand, E. as a control. The blood glucose level was measured in the same manner as above except that the Adenostylis extract was not added. FIG. 2 shows the change in blood glucose level over time in the sucrose load test.

図2に示すように、シュクロースの負荷により、対照においては投与60分後をピークとする顕著な血糖値上昇が認められた。これに対し、E. Adenostylis抽出物は、1g/kg投与群において、投与の30、60分後の血糖値上昇を有意に抑制した。よって、E. Adenostylis抽出物は、シュクロース強制投与ラットの血糖値上昇に対し抑制効果を示すことが明らかとなった。 As shown in FIG. 2, due to the sucrose load, in the control, a significant increase in blood glucose level was observed peaking at 60 minutes after administration. In contrast, E.I. The Adenostylis extract significantly suppressed the increase in blood glucose level 30 and 60 minutes after administration in the 1 g / kg administration group. Thus, E.I. It was revealed that the Adenostylis extract has an inhibitory effect on the increase in blood glucose level of rats forcibly administered with sucrose.

これらの結果から、E. Adenostylis抽出物は、糖負荷による急激な血糖値の上昇を抑制する効果を有し、糖尿病や糖尿病予備軍あるいは肥満に悩む人など、食後血糖値の上昇が気になる人にとって有用であることが示唆された。 From these results, E.I. Adenostylis extract has an effect of suppressing a rapid increase in blood glucose level due to glucose load, and may be useful for those who are concerned about an increase in postprandial blood glucose level, such as those who are suffering from diabetes, pre-diabetes or obesity It was suggested.
