Abstract
Description
本発明は、抗酸化剤および該抗酸化剤を含有する化粧料組成物に関する。さらに詳しくは天然成分であるポインセチア抽出物の抗酸化性やラジカル消去性または活性酸素消去性を利用した効率的で効果の優れた抗酸化剤および化粧料の提供を目的とする。 The present invention relates to an antioxidant and a cosmetic composition containing the antioxidant. More specifically, it is an object to provide an effective and effective antioxidant and cosmetics utilizing the antioxidant property, radical scavenging property or active oxygen scavenging property of poinsettia extract, which is a natural ingredient.
ポインセチア類は、成長すると葉が赤く着色し、花芽の周りに花苞葉（苞）を展開させる。園芸用に改良されたものは葉と苞を合せた植物体の６割以上の広範な部位が赤色に変化し、天然の赤色色素を効率的に生産する。このポインセチアの赤色色素はアントシアニンであることが報告されており、苞中のアントシアニンとしてシアニジン−３−グルコシド（クリサンテミン）、シアニジン−３−ラムノグルコシド（アンチリニン）、ペラルゴニジン−３−グルコシド（カリステフィン）、ペラルゴニジン−３−ラムノグルコシドの４種類が同定されている（非特許文献１）。 Poinsettia, when grown, leaves its leaves colored red and causes flower buds (buds) to develop around the flower buds. What is improved for horticultural use produces a natural red pigment efficiently by changing over 60% of a wide range of plants combined with leaves and straw. This poinsettia red pigment has been reported to be anthocyanin, and as anthocyanins in straw, cyanidin-3-glucoside (chrysanthemine), cyanidin-3-rhamnoglucoside (antilinin), pelargonidin-3-glucoside (calystefin), Four types of pelargonidin-3-rhamnoglucoside have been identified (Non-patent Document 1).
アントシアニンは、合成着色料に比べて安全性が高いことや自然な色合いを有することから、古くから種々の食品に着色料として利用されてきた。また、最近になってアントシアニンが抗酸化性やラジカル消去性、さらには抗変異原性などを示すことが見いだされ、生体内酸化ストレスやＤＮＡ変異を抑止する食品因子としても再評価されている。 Anthocyanins have been used as a colorant in various foods for a long time because they are safer and have a natural color compared to synthetic colorants. Recently, anthocyanins have been found to exhibit antioxidant properties, radical scavenging properties, and antimutagenic properties, and have been reevaluated as food factors that suppress oxidative stress and DNA mutation in vivo.
一方、ポインセチアに関する様々な研究によると、ポインセチアと同属（ユーフォルビア属）である多くの種の植物が生産する有毒のジテルペンが、ポインセチアからは見つかっていない（例えば、非特許文献２）。さらに、ラットを用いたポインセチアの経口毒性試験において、経口量が多量の場合でも、致死や毒性の兆候が見られず、行動にも変化が見られなかったことが報告されている（非特許文献３）。 On the other hand, according to various studies on poinsettia, no toxic diterpenes produced by many species of plants belonging to the same genus (genus Euphorbia) as poinsettia have been found from poinsettia (for example, Non-Patent Document 2). Furthermore, in the oral toxicity test of poinsettia using rats, it was reported that even when the oral dose was large, no signs of lethality or toxicity were observed, and no change in behavior was observed (Non-Patent Document). 3).
従って、赤色色素の高生産性、毒性に関する評価などを顧慮すると、ポインセチア抽出物、特に色素を含む抽出物の抗酸化性を始めとした生理活性を中心とした利用が望まれるが、用途開発、技術開発の報告はあまり見られない。ポインセチアは現在、観葉植物として利用されているが、その利用時期はクリスマスの時期に集中しており、年間を通じた生産体制にはなっていない。ポインセチアの利用効率向上のためには、化学成分の利用を含む広範な用途開発・技術開発が望まれている。 Therefore, considering the high productivity of red pigment, evaluation on toxicity, etc., the use of poinsettia extract, particularly the physiological activity including the antioxidant property of the extract containing pigment, is desired. There are few reports of technological development. Poinsettia is currently used as a foliage plant, but its use is concentrated during the Christmas season and is not a production system throughout the year. In order to improve the utilization efficiency of poinsettia, a wide range of application development and technology development including utilization of chemical components is desired.
従って、本発明の目的は、上記の問題を解決し、色素などのポインセチア抽出物の活用を図ることにより、ポインセチアの一時期に焦点を絞った生産体制を改善し、利用効率を増大させながら、天然成分であるポインセチア抽出物の優れた抗酸化性やラジカル消去性や活性酸素消去性を利用した効率的で効果の優れた抗酸化剤および化粧料組成物を提供することである。 Therefore, the object of the present invention is to solve the above problems and improve the production system focusing on a period of poinsettia by increasing the use efficiency of poinsettia extracts such as pigments, while increasing the utilization efficiency. An object of the present invention is to provide an effective and effective antioxidant and cosmetic composition utilizing the excellent antioxidant property, radical scavenging property and active oxygen scavenging property of poinsettia extract as a component.

本発明の化粧料組成物に使用されるポインセチア抽出物の使用量は限定されないが、化粧料１００質量部に対して、ポインセチア抽出物は乾燥分として０．００００１〜２０質量部程度で使用され、特に０．０００５〜５質量部の範囲の時に好適である。また、抽出液の場合は、この乾燥分換算量で使用される。 The amount of the poinsettia extract used in the cosmetic composition of the present invention is not limited, but the poinsettia extract is used at a dry content of about 0.00001 to 20 parts by mass with respect to 100 parts by mass of the cosmetic. It is particularly suitable for the range of 0.0005 to 5 parts by mass. In the case of an extract, it is used in an amount equivalent to this dry matter.
ポインセチア由来抽出物による抗酸化性の発現は、以下のメカニズムによって行われると考えられる。一般に、抗酸化性とは、電子が奪われる反応に抗する性質と定義されるが、具体的には様々な形で生体にとって不都合状態を惹起させる活性酸素・フリーラジカルによる水素引き抜き反応や該活性酸素・フリーラジカルによって引き起こされるラジカル連鎖反応を停止させる性質である。この場合、活性酸素とは三重項酸素（大気中の酸素分子）がより反応性の高い物質に変化したものの総称を言うが、一般的には、スーパーオキシドアニオンラジカル、ヒドロキシラジカル、一重項酸素、過酸化水素の反応性や毒性が特に強い４種を指す。 Antioxidant expression by the poinsettia-derived extract is considered to be performed by the following mechanism. In general, antioxidation is defined as a property that resists the reaction of depriving electrons. Specifically, the hydrogen abstraction reaction by active oxygen and free radicals that cause inconvenience for the living body in various forms, and the activity. It has the property of stopping the radical chain reaction caused by oxygen and free radicals. In this case, active oxygen is a generic term for triplet oxygen (oxygen molecules in the atmosphere) that has changed to a more reactive substance, but in general, superoxide anion radical, hydroxy radical, singlet oxygen, Four types with particularly strong reactivity and toxicity of hydrogen peroxide.
ここで、スーパーオキシドアニオンラジカルとヒドロキシラジカルはフリーラジカルである。フリーラジカルとは１つ以上の不対電子を持つ分子または原子と定義されるが、過酸化水素からも紫外線などによりフリーラジカルであるヒドロキシラジカルが発生する。また、スーパーオキシドアニオンラジカルも過酸化水素とすばやく反応し、ヒドロキシラジカルを発生させる。ヒドロキシラジカルは細胞膜を構成している脂質と比較的容易に反応し、脂質を毒性の高い過酸化脂質に変え、次々に反応を起こさせ、生体成分を傷害する。また、これらの活性酸素・フリーラジカルは、皮膚の真皮中の細胞間マトリックスを変性させ、真皮を構成する線維芽細胞に傷害を与える。 Here, the superoxide anion radical and the hydroxy radical are free radicals. A free radical is defined as a molecule or atom having one or more unpaired electrons, but a hydrogen radical is generated from hydrogen peroxide by ultraviolet rays or the like. Superoxide anion radicals also react quickly with hydrogen peroxide to generate hydroxy radicals. Hydroxyl radicals react with lipids that make up cell membranes relatively easily, change lipids into highly toxic lipid peroxides, cause reactions one after another, and damage biological components. In addition, these active oxygens and free radicals denature the intercellular matrix in the dermis of the skin and damage the fibroblasts constituting the dermis.
細胞間マトリックスはコラーゲン、エラスチン、フィブロネクチン、ムコ多糖、プロテオグリカンなどから構成されるが、規則的な繊維構造を持つコラーゲン構造が活性酸素・フリーラジカルにより破壊されると、皮膚の張りがなくなり、しわを形成する一因となる。さらに、皮膚の弾力や伸縮に関係するエラスチンも活性酸素・フリーラジカルにより容易に分解され、その結果、しわ、たるみ、柔軟性低下といった皮膚老化を招来すると考えられる。また、活性酸素・フリーラジカルにより線維芽細胞のＤＮＡが損傷されると、皮膚がんを生ずる原因となる。 The intercellular matrix is composed of collagen, elastin, fibronectin, mucopolysaccharide, proteoglycan, etc., but when the collagen structure with a regular fiber structure is destroyed by active oxygen and free radicals, the tension of the skin disappears and wrinkles Contributes to the formation. Furthermore, it is considered that elastin related to skin elasticity and stretching is also easily decomposed by active oxygen and free radicals, resulting in skin aging such as wrinkles, sagging and reduced flexibility. In addition, if the DNA of fibroblasts is damaged by active oxygen and free radicals, it causes skin cancer.
アントシアニンなどのポインセチア由来抽出中の抗酸化成分は、その構造中のフェノール性水酸基が水素供与性、さらには該水素供与により発生するラジカルによるラジカルカップリング性により上記のヒドロキシラジカルやスーパーオキシドアニオンラジカルなどのフリーラジカルを消去させ、抗酸化性を発揮し、ヒドロキシラジカル、スーパーオキシドアニオンラジカル、さらには過酸化水素由来の生体成分に対する傷害を防御すると思われる。 Antioxidant components in poinsettia-derived extractions such as anthocyanins include the above-mentioned hydroxy radicals and superoxide anion radicals due to the hydrogen-donating property of the phenolic hydroxyl group in the structure and the radical coupling properties by radicals generated by the hydrogen donation. It is considered that the free radicals are eliminated, exhibit antioxidant properties, and protect against damage to biological components derived from hydroxy radicals, superoxide anion radicals, and hydrogen peroxide.
一方、一重項酸素に対しては、一重項酸素がポインセチア由来アントシアニジンの２位の炭素に結合して、ヒドロペルオキシドを生じ、さらにはＢ環部分が分離し、安息香酸誘導体を生じさせることにより、その反応性を不活化させ、皮膚におけるＳＯＤやカタラーゼなどの酸化防御システムの補完に有効的に機能すると考えられる。また、上記のラジカルのほかに、脂質ペルオキシルラジカル、アルコキシラジカル、ヒドロペルオキシラジカル、一酸化窒素、二酸化窒素などのフリーラジカルの消去にも有効に作用すると思われる。総じて、大部分の活性酸素・フリーラジカルの消去に有効に作用し、老化（しわ、たるみ、柔軟性低下など）や炎症、疾患など該活性酸素・フリーラジカルに起因する様々な症状を緩和できる。 On the other hand, for singlet oxygen, the singlet oxygen is bonded to the carbon at the 2-position of poinsettia-derived anthocyanidin to generate hydroperoxide, and further, the B ring portion is separated to generate a benzoic acid derivative. It is considered that the reactivity is inactivated, and it effectively functions in complementing oxidation protection systems such as SOD and catalase in the skin. In addition to the above-mentioned radicals, it is considered to effectively act to eliminate free radicals such as lipid peroxyl radicals, alkoxy radicals, hydroperoxy radicals, nitric oxide and nitrogen dioxide. In general, it effectively works to eliminate most of the active oxygen and free radicals, and can alleviate various symptoms caused by the active oxygen and free radicals such as aging (wrinkles, sagging, reduced flexibility, etc.), inflammation, and diseases.
