Description

化粧料、飲料、食品又は飼料等の原料として、あるいは、これら製品又は原料に添加することにより、メラニン生成抑制及びそれらの酸化による品質低下防止や、それらを利用する人又は動物の生体内に発生する活性酸素やフリーラジカルの発生を消去もしくは抑制する天然物由来の抗酸化能を有する微生物培養物であって、緑茶、黒茶及びヨモギ抽出液を主成分とする培地で培養することにより得られる微生物培養物に関する。さらに、本発明はそれらを用いた化粧料、飲料、食品又は飼料に関する。   As a raw material for cosmetics, beverages, foods, feeds, etc., or by adding to these products or raw materials, it suppresses melanin production and prevents quality deterioration due to their oxidation, and occurs in the living body of humans or animals using them. Microbial culture having antioxidative ability derived from natural products that eliminates or suppresses generation of active oxygen and free radicals, and is obtained by culturing in a medium mainly composed of green tea, black tea and mugwort extract Relates to microbial cultures. Furthermore, this invention relates to the cosmetics, drink, foodstuff, or feed using them.

日焼け等による肌の色黒化、シミ、ソバカス等は、黒褐色無定形の色素であるメラニンの生成によるものと考えられている。そこで、化粧品には、メラニン生成抑制物質が添加されていることが多い。   Skin darkening due to sunburn or the like, spots, freckles, etc. are thought to be due to the production of melanin, an amorphous pigment of blackish brown color. Therefore, melanin production-suppressing substances are often added to cosmetics.

このような目的のために、コウジ酸及びその誘導体、アスコルビン酸及びその誘導体、ハイドロキノン及びその配糖体等、動植物からの抽出物を成分とするメラニン抑制物質が知られている。   For such purposes, melanin-inhibiting substances containing extracts from animals and plants such as kojic acid and its derivatives, ascorbic acid and its derivatives, hydroquinone and its glycosides are known.

また、昨今、悪性新生物(がん等)、脳血管疾患や糖尿病などの生活習慣病が死亡原因の上位を占めている。その生活習慣病を引き起こす大きな原因として、活性酸素やフリーラジカルがある。抗酸化物質には、化粧料、飲料、食品又は飼料などに添加し、品質低下の防止及び品質保持の目的で使用されるものと、生体内に発生する活性酸素やフリーラジカルの発生を消去もしくは抑制する目的で使用されるものとがある。   In addition, malignant neoplasms (cancer, etc.), lifestyle-related diseases such as cerebrovascular diseases and diabetes are the top causes of death. There are active oxygen and free radicals as major causes of lifestyle-related diseases. Antioxidants can be added to cosmetics, beverages, foods, feeds, etc. and used for the purpose of preventing quality deterioration and maintaining quality, and eliminate the generation of active oxygen and free radicals generated in the body. Some are used for control purposes.

化粧料、飲料、食品又は飼料などに含まれている油脂類が酸化されると、製品の色や風味が悪くなるばかりでなく、褐変や退色、栄養価の低下の原因になる。そこで、化粧料、飲料、食品又は飼料には、品質保持のために抗酸化物質が添加されていることが多い。   Oxidation of fats and oils contained in cosmetics, beverages, foods, feeds, etc. not only deteriorates the color and flavor of the product, but also causes browning, fading and a decrease in nutritional value. Therefore, antioxidants are often added to cosmetics, beverages, foods or feeds to maintain quality.

このような目的のために、飲料、食品又は飼料などの分野で使用されている抗酸化物質としては、例えば、L−アスコルビン酸(ビタミンC、V.C)、エリソルビン酸(イソアスコルビン酸)、トコフェロール(ビタミンE、V.E)などの天然抗酸化物質やジブチルヒドロキシトルエン(BHT)、ブチルヒドロキシアニソール(BHA)などのフェノール系合成抗酸化物質が知られている。   For such purposes, as antioxidants used in the field of beverages, foods or feeds, for example, L-ascorbic acid (vitamin C, VC), erythorbic acid (isoascorbic acid), Natural antioxidants such as tocopherol (vitamin E, VE) and phenolic synthetic antioxidants such as dibutylhydroxytoluene (BHT) and butylhydroxyanisole (BHA) are known.

従来、皮膚美白効果を有する化粧料(化粧水)としては、コウジ酸及びその誘導体、アスコルビン酸及びその誘導体、ハイドロキノン及びその配糖体等、動植物からの抽出物を成分とするものであったが、人体への悪影響や肌荒れ等の心配があった。また、充分に美白効果が得られるものではなかった。   Conventionally, cosmetics (skin lotions) having a skin-whitening effect are composed of extracts from animals and plants such as kojic acid and derivatives thereof, ascorbic acid and derivatives thereof, hydroquinone and glycosides thereof, and the like. There were concerns about adverse effects on the human body and rough skin. Further, a sufficient whitening effect was not obtained.

一方、日焼け等による肌の色黒化、シミ、ソバカス等は、黒褐色無定形の色素であるメラニンの生成によるものと考えられている。
このメラニンは表皮基底層に存在するメラノサイトと呼ばれる色素細胞内のメラノソームにおいて、チロシナーゼによってチロシンから各種メラニン中間代謝産物を経て、酸化重合して生成されると考えられている。
そして、紫外線等により生成された活性酸素がこの反応系を活性化させるためにメラニンが過剰に生成され、皮膚への色素沈着を促進していると考えられている。
On the other hand, skin darkening due to sunburn, stains, freckles, etc. are thought to be due to the production of melanin, a black-brown amorphous pigment.
This melanin is considered to be produced by oxidative polymerization in melanosomes in pigment cells called melanocytes existing in the basal layer of the epidermis by various melanin intermediate metabolites from tyrosine by tyrosinase.
And it is thought that the active oxygen produced | generated by the ultraviolet-ray etc. activates this reaction system, melanin is produced | generated excessively, and the pigmentation to the skin is accelerated | stimulated.

抗酸化物質のL−アスコルビン酸は、水に溶けやすく酸性で強い還元作用があるので良く利用されているが、油脂へは使用しにくく酸性(酸味)が食品の味をかえてしまうことから、果実加工品、漬物などに限られる。また、トコフェロールは油脂成分の不必要な酸化を防ぐのでこれも良く用いられているが、抗酸化能があまり高くないため他の抗酸化物質と併用する必要がある。   The antioxidant substance L-ascorbic acid is often used because it is easily soluble in water and has an acidic and strong reducing action, but it is difficult to use for oils and fats, so acidity changes the taste of food. Limited to processed fruit products and pickles. In addition, tocopherol is also often used because it prevents unnecessary oxidation of fat and oil components, but it has to be used in combination with other antioxidants because its antioxidant ability is not so high.

一方、天然抗酸化物質は合成抗酸化物質と比較してその抗酸化能が劣るという欠点がある。しかし、合成抗酸化物質のジブチルヒドロキシトルエン(BHT)やブチルヒドロキシアニソールは、抗酸化能が強いが遺伝子損傷、変異原性、染色体異常などによる発がん性を誘発する疑わしい食品添加剤とされ、安全性が疑問視されるようになってきた。   On the other hand, natural antioxidants have the disadvantage that their antioxidant ability is inferior to synthetic antioxidants. However, synthetic antioxidants such as dibutylhydroxytoluene (BHT) and butylhydroxyanisole, which have strong antioxidant ability, are regarded as suspicious food additives that induce carcinogenicity due to genetic damage, mutagenicity, chromosomal abnormalities, etc. Has come to be questioned.

化粧品としても、油脂類の酸化防止の為に天然抗酸化物質や合成抗酸化物質が用いられているが、皮膚への影響や肌荒れなどの原因とされ、安全性が疑問視されるようになってきた。
このようなことから、抗酸化能が強く、しかも、汎用性が高く、さらに、天然物由来の安全性の高い抗酸化物質の開発が望まれていた。
As cosmetics, natural antioxidants and synthetic antioxidants are used to prevent the oxidation of fats and oils, but it is considered to be a cause of skin effects and rough skin, and safety is questioned. I came.
For these reasons, it has been desired to develop an antioxidant having strong antioxidant ability, high versatility, and high safety derived from natural products.

天然の抗酸化物質としては、褐変物質、アミノ酸、糖アルコール、果糖、果皮、わさびやカテキンなどが報告されている。また、微生物培養物の抗酸化物質としては、乳酸菌の抽出物に抗酸化効果があることが示されてきている。   As natural antioxidants, browning substances, amino acids, sugar alcohols, fructose, pericarp, wasabi and catechins have been reported. Moreover, it has been shown that the extract of lactic acid bacteria has an antioxidant effect as an antioxidant substance of a microorganism culture.

これらの抗酸化物質は、従来、化粧料、飲料、食品又は飼料などに添加し、品質低下の防止及び品質保持の目的で使用されてきたが、生体内に発生する活性酸素やフリーラジカルを消去もしくは抑制することが明らかになり、生体内抗酸化能が強い天然抽出物の探索が行われるようになってきた。   These antioxidants have been added to cosmetics, beverages, foods, feeds, etc., and have been used for the purpose of preventing quality degradation and maintaining quality, but they eliminate active oxygen and free radicals generated in the living body. Or it became clear that it suppresses, and the search of the natural extract with strong antioxidative ability in a living body has come to be performed.

生体内酸化により発生する活性酸素には、一重項酸素、スーパーオキシド、ヒドロキシルラジカル、過酸化水素の4種、また、フリーラジカルには、アルキルヒドロペルオキシド、ヒドロペルオキシルラジカルなど10種以上が知られている。抗酸化能は、一般的に1,1−ジフェニル−2−ピクリルヒドラジル(DPPH)を用いたラジカル消去活性を測定することで判定できる。   There are four types of active oxygen generated by in-vivo oxidation: singlet oxygen, superoxide, hydroxyl radical, and hydrogen peroxide, and more than 10 types of free radicals such as alkyl hydroperoxide and hydroperoxyl radical. ing. Antioxidant ability can generally be determined by measuring radical scavenging activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH).

生体内酸化により生体への影響として、老化、生活習慣病及びがんが引き起こされると考えられている。老化は、運動機能や内臓の機能の低下、物忘れ、眼の白内障、皮膚のしわなど、病気とまではいかない衰えのほか、血管が衰えて動脈硬化などにかかりやすくなる。生活習慣病としては、特に関係が深いと考えられているのが動脈硬化と糖尿病で、他にも肝機能障害、リウマチ性関節炎など挙げられる。   It is thought that aging, lifestyle-related diseases and cancer are caused by in vivo oxidation as an effect on the living body. Aging is not limited to illness such as decreased motor function and visceral function, forgetfulness, eye cataracts, skin wrinkles, etc., and blood vessels tend to suffer from arteriosclerosis. As lifestyle-related diseases, arteriosclerosis and diabetes are considered to be particularly closely related, and other examples include liver dysfunction and rheumatoid arthritis.

また、がんについては、酸化によってDNAを構成する物質を変質させて傷をつけ、別の細胞が再生される際に突然変異を起こす原因の一つとされている。このような疾患を防止する上で、生体内酸化を防止し、あるいは、抑制する抗酸化物質が注目され、機能性食品、特定保健用食品やサプリメントして研究開発されている。   In addition, cancer is considered to be one of the causes of mutation when a substance constituting DNA is altered and damaged by oxidation and another cell is regenerated. In order to prevent such diseases, antioxidant substances that prevent or suppress in-vivo oxidation have attracted attention and have been researched and developed as functional foods, foods for specified health use and supplements.

このような用途の抗酸化物質として、カロチノイド類(ベータカロチン、リコペン、フコキサンチン)、フェノール化合物類(フラボノイド、アントシアニン、カテキン)、含硫化物やベータ・ジケトン類などの植物由来、微生物培養物ではDHA(ドコサヘキサエン酸)、EPA(エイコサペンタエン酸)などがある。   Antioxidants for such applications include carotenoids (beta-carotene, lycopene, fucoxanthin), phenolic compounds (flavonoids, anthocyanins, catechins), plant-derived sulfides and beta-diketones, and microbial cultures. Examples include DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid).

本発明の第一の目的は、このような天然抽出物であって安全性が高く、抗酸化能が強いメラニン生成抑制効果に優れ、皮膚美白効果が高い化粧料の提供及び様々な飲料、食品又は飼料など、汎用性が高く、製品本来の味や風味が維持でき、また、生体内抗酸化能にも効果のある緑茶、黒茶及びヨモギ抽出液を主成分とする培地で培養することにより得られる微生物培養物を提供することにある。また、本発明の第二の目的は、それらを用いた様々な化粧料、飲料、食品又は飼料を合わせて提供することにある。   The first object of the present invention is such a natural extract that is highly safe, has a strong antioxidant ability, is excellent in melanin production inhibitory effect, has a high skin whitening effect, and provides various cosmetics and various beverages and foods. Or by culturing in a medium mainly composed of green tea, black tea and mugwort extract, which is highly versatile, can maintain the original taste and flavor of the product, and is also effective for in vivo antioxidant capacity The object is to provide the resulting microbial culture. The second object of the present invention is to provide various cosmetics, beverages, foods or feeds using them.

ケフィア粒から分離された微生物群及び菌株ラクトバシラシー(Lactobacillaceae)科の新種であるラクトバシラス属(Lactobacillus sp.)SIID1719−6bを、緑茶、黒茶及びヨモギ抽出液を主成分とする培地で単独培養することにより得られた微生物培養物が、メラニン生成抑制効果及び抗酸化能を有するか、以下菌株の評価試験を行った。その結果、微生物群及びラクトバシラス属(Lactobacillus sp.)SIID1719−6b単独でメラニン生成抑制効果及び抗酸化能を有していた。さらに、本発明では、ラクトバシラス属(Lactobacillus sp.)SIID1719−6bと安全性の確認できている微生物を共生し、同様の作用を示すものであれば、いずれも使用できる。
なお、ラクトバシラシー(Lactobacillaceae)科の新種であるラクトバシラス属(Lactobacillus sp.)SIID1719−6b(FERM AP−20062)は、すでに独立行政法人産業技術総合研究所特許生物寄託センターに寄託済みである。
Lactobacillus sp. SIID1719-6b, a new species of the microbial community isolated from kefir grains and the strain Lactobacillaceae, is cultured alone in a medium mainly composed of green tea, black tea and mugwort extract Whether the microbial culture obtained by doing so has a melanin production inhibitory effect and an antioxidant ability was tested for the following strains. As a result, the microorganism group and Lactobacillus sp. SIID1719-6b alone had a melanin production inhibitory effect and an antioxidant ability. Furthermore, in the present invention, any microorganism may be used as long as it coexists with Lactobacillus sp. SIID1719-6b and a microorganism whose safety has been confirmed and exhibits a similar action.
In addition, Lactobacillus sp. SIID1719-6b (FERM AP-20062), a new species of the Lactobacillaceae family, has already been deposited at the National Institute of Advanced Industrial Science and Technology Patent Organism Depositary.

代表例として、菌株ラクトバシラシー(Lactobacillaceae)科の新種であるラクトバシラス属(Lactobacillus sp.)SIID1719−6bの緑茶、黒茶及びヨモギ抽出液を主成分とする培地での培養及び、メラニン生成抑制効果及び抗酸化評価試験方法を次のように実施した。   As a representative example, cultivation of Lactobacillus sp. SIID1719-6b, a new species of the strain Lactobacillaceae, in a medium mainly composed of green tea, black tea, and mugwort extract, and melanin production inhibitory effect And the antioxidant evaluation test method was implemented as follows.

(メラニン生成抑制効果試験)
先ず、B16mouse melanoma cellを2.0×105cell/wellとなるように細胞培養用wellに添加し、RPMI1640培地で培養した。24時間後にSIID1719−6bを緑茶、黒茶、ヨモギ抽出液が6.67:1.665:1.665の割合で調製した培地で48時間培養した培養物(B3溶液)を、B16mouse melanoma cellが良好な生育の確認された終濃度を全培養液の1/50となるように添加した。また、ポジティブコントロールとして、代表的なメラニン抑制物質であるコウジ酸を終濃度100μg/mlとなるように、ネガティブコントロールとして、蒸留水を10倍希釈となるように添加し、3日間培養した。次に、10%DMSO−1NNaOHを用いて細胞からメラニンを溶かし出し、470nmの吸光度を測定することでメラニンを定量した。各サンプルのメラニン生成抑制効果は、1/50B3溶液、コウジ酸で培養した細胞のメラニン量(S)と、蒸留水(C)で得られた細胞のメラニン量を比較することで求めた(次式(1)参照)。その結果を、図1のグラフにメラニン生成抑制効果として示す。
メラニン生成抑制効果で知られているコウジ酸よりも、B3溶液の全培養液の終濃度を1/50にした1/50B3溶液培地の方が、メラニン生成抑制効果が高まることが確認された。
(Melanin production inhibitory effect test)
First, B16mouse melanoma cell was added to a cell culture well so as to be 2.0 × 10 5 cells / well and cultured in RPMI1640 medium. After 24 hours, a culture (B3 solution) obtained by cultivating SIID1719-6b with green tea, black tea, mugwort extract at a ratio of 6.67: 1.665: 1.665 for 48 hours was used as B16mouse melanoma cell. The final concentration confirmed to have good growth was added to 1/50 of the total culture solution. As a positive control, kojic acid, which is a typical melanin inhibitor, was added to a final concentration of 100 μg / ml, and distilled water was added to a 10-fold dilution as a negative control, and cultured for 3 days. Next, melanin was quantified by dissolving melanin from the cells using 10% DMSO-1N NaOH and measuring the absorbance at 470 nm. The melanin production inhibitory effect of each sample was determined by comparing the amount of melanin (S) of cells cultured with 1 / 50B3 solution and kojic acid and the amount of melanin of cells obtained with distilled water (C) (next) (See Equation (1)). The result is shown as a melanin production inhibitory effect in the graph of FIG.
It was confirmed that the 1/50 B3 solution medium in which the final concentration of the whole culture solution of the B3 solution was 1/50 was more effective than the kojic acid known for the melanin production suppressing effect.

(抗酸化能試験)
抗酸化能試験は次のように実施した。
菌株ラクトバシラシー(Lactobacillaceae)科の新種であるラクトバシラス属(Lactobacillus sp.)SIID1719−6bを緑茶、黒茶、ヨモギ抽出液が6.67:1.665:1.665の割合で調製した培地で48時間培養し、この培養物(B3溶液)とコントロールとしてSIID1719−6bを添加していない培地のみ(B3培地)を終濃度0.2%となるように添加し、DPPHラジカル消去率を確認した。B3溶液の抗酸化能を、ブランクとして蒸留水を用いて比較した。
(Antioxidant ability test)
Antioxidant ability test was carried out as follows.
Lactobacillus sp. SIID1719-6b, a new species of the family Lactobacillaceae, is prepared with a green tea, black tea, mugwort extract at a ratio of 6.67: 1.665: 1.665. After culturing for 48 hours, this culture (B3 solution) and only a medium without addition of SIID1719-6b (B3 medium) as a control were added to a final concentration of 0.2%, and the DPPH radical scavenging rate was confirmed. . The antioxidant capacity of the B3 solution was compared using distilled water as a blank.

先ず、96wellマイクロプレートの各wellに、199.6μlの0.1mM DPPH(50%エタノールに溶解)を添加する。次に、B3溶液、B3培地、ブランクの各0.4μlをそれぞれwellに添加(終濃度0.2%)して、ラジカル消去反応を開始させた。添加直後(0分)及び30分後のλ=517nmの吸光度をマイクロプレートリーダーで測定し、B3溶液、B3培地とブランクの吸光度より、ラジカル消去率を求めた。その結果を、図2のグラフに抗酸化能として示す。
B3培地と比較してB3溶液の抗酸化能がおおよそ3.2倍高かったことから、菌株を添加することにより高い抗酸化能が得られることが確認できた。
First, 199.6 μl of 0.1 mM DPPH (dissolved in 50% ethanol) is added to each well of a 96-well microplate. Next, 0.4 μl of each of B3 solution, B3 medium, and blank was added to each well (final concentration 0.2%) to initiate radical scavenging reaction. The absorbance at λ = 517 nm immediately after addition (0 minutes) and after 30 minutes was measured with a microplate reader, and the radical scavenging rate was determined from the absorbance of the B3 solution, B3 medium and blank. The results are shown as antioxidant ability in the graph of FIG.
Since the antioxidant capacity of the B3 solution was approximately 3.2 times higher than that of the B3 medium, it was confirmed that a high antioxidant capacity was obtained by adding the strain.
