【発明の属する技術分野】
本発明は、植物からの抽出物を有効成分とする抗酸化剤、活性酸素消去剤及びラジカル消去剤、並びに植物からの抽出物を配合した皮膚化粧料及び美容用飲食品に関するものである。
【0002】
【従来の技術】
近年、特に生体成分を酸化させる要因として、活性酸素が注目されており、その生体への悪影響が問題となっている。
活性酸素は、生体細胞内のエネルギー代謝過程で生じるものであり、スーパーオキサイド(即ち酸素分子の一電子還元で生じるスーパーオキシドアニオン(・O2-)、過酸化水素(H2O2)、一重項酸素(1O2)、ヒドロキシラジカル(・OH)等がある。これら活性酸素は食細胞の殺菌機構にとって必須でありウイルスや癌細胞の除去に重要な働きを果たしているが、活性酸素の過剰な生成は生体内の膜や組織を構成する生体内分子を攻撃し、各種疾患を誘発する。例えば、活性酸素は、コラーゲン等の生体組織を分解、変性あるいは架橋したり、油脂類を酸化して細胞に障害を与える過酸化脂質を生成したりすると考えられており、活性酸素によって引き起こされるこれらの障害が、皮膚のしわ形成や皮膚の弾力性低下等の老化の原因になるものと考えられている。
【0003】
【発明が解決しようとする課題】
したがって、活性酸素や生体内ラジカルの発生の阻害・抑制により、過酸化脂質の生成の抑制等を通じて皮膚のしわの形成や弾力性低下等の皮膚の老化を予防・治療できるものと考えられる。
【0004】
そこで、本発明は、第一に、天然物の中から活性酸素消去作用及び/又はラジカル消去作用を有するものを見出し、それを有効成分とした抗酸化剤を提供することを目的とする。
【0005】
また、本発明は、第二に、天然物の中から活性酸素消去作用を有するものを見出し、それを有効成分とした活性酸素消去剤を提供することを目的とする。
【0006】
さらに、本発明は、第三に、天然物の中からラジカル消去作用を有するものを見出し、それを有効成分としたラジカル消去剤を提供することを目的とする。
【0007】
さらに、本発明は、第四に、天然物の中から活性酸素消去作用及び/又はラジカル消去作用を有するものを見出し、それを配合した皮膚化粧料を提供することを目的とする。
【0008】
さらに、本発明は、第五に、天然物の中から活性酸素消去作用及び/又はラジカル消去作用を有するものを見出し、それを配合した美容用飲食品を提供することを目的とする。
【0009】
【課題を解決するための手段】
上記目的を解決するため、本発明の抗酸化剤、活性酸素消去剤及びラジカル消去剤は、木棉及び/又は黄花倒水蓮からの抽出物を有効成分として含有することを特徴とし、本発明の皮膚化粧料及び美容用飲食品は、木棉及び/又は黄花倒水蓮からの抽出物を配合したことを特徴とする。
【0010】
【発明の実施の形態】
以下、本発明について詳細に説明する。
本発明において、「木棉花及び/又は黄花倒水蓮からの抽出物」には、木棉花及び/又は黄花倒水蓮を抽出原料として得られる抽出液、該抽出液の希釈液若しくは濃縮液、該抽出液を乾燥して得られる乾燥物、又はこれらの粗精製物若しくは精製物のいずれもが含まれる。
【0011】
抽出原料として用いる植物は、木棉及び/又は黄花倒水蓮である。木棉(モクメン)(学名:Gossampinus malabaricum)は、パンヤ科に属する落葉高木であって、広東、海南、広西、福建、台湾、雲南等に分布しており、これらの地域から容易に入手可能である。また、黄花倒水蓮(コウカトウスイレン)(学名:Polygala fallax)は、ヒメハギ科に属する低木であって、中南、華東、四川等に分布しており、これらの地域から容易に入手可能である。
【0012】
抽出原料として用いる植物の構成部位は特に限定されるものではなく、木棉については、例えば葉部、枝部、花、種子、樹皮、根部等の構成部位を、黄花倒水蓮については、例えば葉部、枝部、花、種子、根部等の構成部位を抽出原料として用いることができる。これらの構成部位のうち、木棉については特に花(木棉の花は「木棉花」と呼ばれる)、黄花倒水蓮については特に根部を抽出原料として用いることが好ましい。ここで、「花」とは、一般に、種子植物の有性生殖にかかわる器官の総体をいい、葉の変形である花葉と茎の変形である花軸とから構成され、花葉には、萼、花弁、雄しべ、心皮などの器官が含まれる。本発明において抽出原料として使用する「花」には、種子植物の有性生殖にかかわる器官の総体の他、その一部、例えば、花葉、花被(萼と花冠)、花冠、花弁等も含まれる。
【0013】
木棉及び/又は黄花倒水蓮からの抽出物に含有される活性酸素消去作用及び/又はラジカル消去作用を有する物質の詳細は不明であるが、植物の抽出に一般に用いられている抽出方法によって、木棉及び/又は黄花倒水蓮から活性酸素消去作用及び/又はラジカル消去作用を有する抽出物を得ることができる。例えば、抽出原料を乾燥した後、そのまま、又は粗砕機を用いて粉砕し、抽出溶媒による抽出に供することにより得ることができる。この際、抽出原料の乾燥は天日で行ってもよいし、通常使用される乾燥機を用いて行ってもよい。また、木棉及び/又は黄花倒水蓮は、ヘキサン、ベンゼン等の非極性溶媒によって脱脂等の前処理を施してから抽出原料として使用してもよい。脱脂等の前処理を行うことにより、木棉及び/又は黄花倒水蓮の極性溶媒による抽出処理を効率よく行うことができる。
【0014】
抽出溶媒としては、極性溶媒を用いることが好ましく、水若しくは親水性有機溶媒又はこれらの混合液を室温又は溶媒の沸点以下の温度で用いることが特に好ましい。
【0015】
抽出溶媒として使用し得る水としては、純水、水道水、井戸水、鉱泉水、鉱水、温泉水、湧水、淡水等の他、これらに各種処理を施したものが含まれる。水に施す処理としては、例えば、精製、加熱、殺菌、ろ過、イオン交換、浸透圧の調整、緩衝化等が含まれる。従って、本発明において抽出溶媒として使用し得る水には、精製水、熱水、イオン交換水、生理食塩水、リン酸緩衝液、リン酸緩衝生理食塩水等も含まれる。
【0016】
抽出溶媒として使用し得る親水性有機溶媒としては、例えば、メタノール、エタノール、プロピルアルコール、イソプロピルアルコール等の炭素数1〜5の低級アルコール;アセトン、メチルエチルケトン等の低級脂肪族ケトン;1,3−ブチレングリコール、プロピレングリコール、グリセリン等の炭素数2〜5の多価アルコールなどが挙げられる。
【0017】

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail.
In the present invention, the “extract from Kiso flower and / or yellow fallen water lotus” includes an extract obtained by using Kiso flower and / or yellow fallen water lotus as an extraction raw material, a diluted or concentrated solution of the extract, The dried product obtained by drying the extract, or any of these roughly purified products or purified products are included.
[0011]
The plant used as an extraction raw material is a mallet and / or a yellow flower falling water lotus. Mokumen (scientific name: Gossampinus malabaricum) is a deciduous tree belonging to the family Panyaceae, distributed in Guangdong, Hainan, Guangxi, Fujian, Taiwan, Yunnan, etc., and is easily available from these areas . In addition, Koukatousuren (scientific name: Polygala fallax) is a shrub belonging to the family Himehagi, distributed in the central South, East China, Sichuan, etc., and is easily available from these areas .
[0012]
There are no particular restrictions on the constituent parts of the plant used as the extraction raw material, and for example, for the koji, the constituent parts such as leaves, branches, flowers, seeds, bark, roots, etc. Components such as parts, branches, flowers, seeds, and roots can be used as extraction raw materials. Among these constituent parts, it is particularly preferable to use a flower as a raw material for the extraction of the koji (in particular, the flower of the mushroom is referred to as “Kiso flower”), and particularly for the yellow fallen water lotus. Here, the "flower" generally refers to the whole organ involved in sexual reproduction of a seed plant, and is composed of a flower leaf that is a leaf deformation and a flower axis that is a stem deformation. It includes organs such as pupae, petals, stamens, and heart skin. The “flower” used as an extraction raw material in the present invention includes not only the whole organs involved in sexual reproduction of seed plants, but also some of them, such as flower leaves, flower coats (buds and corolla), corolla, petals, etc. included.
[0013]
Details of the substance having an active oxygen scavenging action and / or radical scavenging action contained in an extract from a koji and / or yellow flower fallen water lotus are unknown, but by an extraction method generally used for plant extraction, An extract having an active oxygen scavenging action and / or a radical scavenging action can be obtained from a mallet and / or a yellow flower falling water lotus. For example, it can be obtained by drying the raw material for extraction and pulverizing it as it is or using a crusher and subjecting it to extraction with an extraction solvent. At this time, the extraction raw material may be dried in the sun or using a commonly used dryer. Further, the koji and / or yellow flower fallen water lotus may be used as a raw material for extraction after pretreatment such as degreasing with a nonpolar solvent such as hexane or benzene. By performing pretreatment such as degreasing, extraction treatment with a polar solvent of a mallet and / or yellow flower fallen water lotus can be performed efficiently.
[0014]
As the extraction solvent, it is preferable to use a polar solvent, and it is particularly preferable to use water, a hydrophilic organic solvent, or a mixture thereof at room temperature or a temperature not higher than the boiling point of the solvent.
[0015]
Examples of water that can be used as the extraction solvent include pure water, tap water, well water, mineral spring water, mineral water, hot spring water, spring water, fresh water, and the like, as well as water that has been subjected to various treatments. Examples of the treatment applied to water include purification, heating, sterilization, filtration, ion exchange, adjustment of osmotic pressure, buffering, and the like. Therefore, the water that can be used as the extraction solvent in the present invention includes purified water, hot water, ion-exchanged water, physiological saline, phosphate buffer, phosphate buffered saline, and the like.
[0016]
Examples of the hydrophilic organic solvent that can be used as the extraction solvent include lower alcohols having 1 to 5 carbon atoms such as methanol, ethanol, propyl alcohol, and isopropyl alcohol; lower aliphatic ketones such as acetone and methyl ethyl ketone; 1,3-butylene. Examples thereof include polyhydric alcohols having 2 to 5 carbon atoms such as glycol, propylene glycol and glycerin.
[0017]
When using the liquid mixture of 2 or more types of polar solvents as an extraction solvent, the mixing ratio can be adjusted suitably. For example, when using the liquid mixture of water and a lower aliphatic alcohol, the mixing ratio of water and a lower aliphatic alcohol can be set to 9: 1 to 1: 9 (weight ratio).
[0018]
The extraction treatment is not particularly limited as long as the soluble component contained in the koji and / or yellow flower fallen water can be eluted in the extraction solvent, and can be performed according to a conventional method. In the extraction process, it is not necessary to adopt a special extraction method, and any apparatus can be used at room temperature or under reflux heating.
[0019]
Specifically, the raw material for extraction is put into a treatment tank filled with the extraction solvent, and is usually left standing for 1 to 3 hours with occasional stirring to elute soluble components, followed by filtration to remove solid matter. An extract is obtained by removing and evaporating the extraction solvent from the resulting extract and drying. The amount of the extraction solvent is usually 5 to 15 times the weight of the extraction raw material (weight ratio), and the extraction temperature is usually from room temperature to 95 ° C.
[0020]
The obtained extract is diluted, concentrated, dried, purified, etc. according to a conventional method in order to obtain a diluted or concentrated solution of the extract, a dried product of the extract, or a crude purified product or a purified product thereof. Processing may be performed.
[0021]
The obtained extract can be used as it is as an antioxidant, active oxygen scavenger or radical scavenger, but a concentrated or dried product is easier to use. Formulation of an extract from a koji and / or yellow flower fallen lotus can be performed according to a conventional method. When formulating, a pharmaceutically acceptable carrier such as dextrin, cyclodextrin, or any other auxiliary agent can be added for ease of storage and handling, and it can be added from a mallet and / or yellow fallen water lily. The extract can be formulated into any dosage form such as powder, granule, tablet.
[0022]
Since the extract from the kiso and / or the yellow fallen water lotus has a peculiar odor, it is possible to carry out purification for the purpose of decolorization, deodorization and the like within a range not causing a decrease in its physiological activity. In addition, when added to cosmetics, foods and drinks, etc., it is not used in large quantities, so there is no practical problem even if it is not purified. Specifically, purification can be performed by activated carbon treatment, adsorption resin treatment, ion exchange resin treatment, or the like.
[0023]
The extract from the koji and / or yellow flower fallen lotus obtained as described above has an active oxygen scavenging and / or radical scavenging action, and these actions are used to eliminate antioxidants and active oxygen. It can be used as an active ingredient of an agent or radical scavenger.
[0024]
Here, the antioxidant effect of the extract from the mallet and / or yellow flower falling water lotus is exhibited based on the active oxygen scavenging action and / or the radical scavenging action. “Active oxygen” includes superoxide, hydrogen peroxide, hydroxy radical, singlet oxygen and the like. The “radical” means a molecule or atom having one or more unpaired electrons, and includes superoxide, hydroxy radical, DPPH and the like.
