Description

【0001】
【産業上の利用分野】
本発明は、抗炎症、抗かゆみ剤、さらに詳しくは、シソ科メンタ(Mentha)属植物から得られたある種の成分を有効成分とする、抗炎症、かゆみの防止、抑制、創傷治癒や、肌あれ防止、肌あれの改善等に優れた化粧料、医薬、医薬部外品として有用な外用剤に関する。
【0002】
【従来の技術および課題】
かゆみを伴う疾患はアトピー性皮膚炎、老人性掻痒症などの乾燥性掻痒症が挙げられるが、このような皮膚疾患は患者に精神的苦痛を与えると共に掻くことにより症状を悪化させる。これら皮膚疾患を予防または治療すべく、従来より各種の外用剤が提案されている。このうち、特に、皮膚に対する緩和な作用を考慮して、生薬を主成分とするものが注目されている(例えば、特開平1−319424号)。しかし、生薬成分といえども皮膚に作用する上で好ましいものばかりとは限らない。このような観点からすると、今までのところ、かゆみを伴う疾患に対して満足すべき効果の得られる外用剤は見当たらない。
このような現状に鑑み、本発明者らは、炎症に対して強い活性を有し、しかも安全性の点でも心配のない天然物系の抗炎症、抗かゆみ剤を提供すべく、鋭意研究を重ねた。
【0003】
すなわち、かゆみは皮膚上層に刺激を加えることにより起こり、その刺激となる化学物質ではヒスタミンがよく知られている。ヒスタミンは肥満細胞からの脱顆粒により組織内に遊離し、かゆみを起こし、これは炎症が起こる初期反応であることから(久保田淳ほか編集:現代皮膚科学体系3C、石橋康正ほか編集:痒みの強い皮膚疾患)、本発明者らは、種々の植物エキスについてヒスタミン遊離抑制作用(in vitro)および起炎剤(compound 48/80) に対する抗炎症作用(in vivo)を指標にして探索した。その結果、シソ科メンタ(Mentha)属植物(以下、ミント草という)の精油採取に際する水蒸気蒸留で生じる残渣のうちに強い抗炎症作用を有する成分があることを見いだし、本発明を完成するに至った。
ミント葉はその精油成分にメントールを含有し、化粧用、歯科用、料理用として、ハッカの風味で幅広く用いられている。また、全草や油は芳香性興奮薬、駆風、防腐、鎮痙薬として利用されてきた。しかし、精油成分を除いた部分、すなわち、水蒸気蒸留残渣については、消臭物質の製造方法(特開昭59−6056〜6058号、特公昭64−1145号)および口腔用組成物(特開昭62−155210号)が知られている程度であり、その生理活性や抗炎症、抗かゆみ作用については未だ報告されていない。
【0004】
【課題を解決するための手段】
本発明は、有効成分として、シソ科メンタ(Mentha)属植物の水蒸気蒸留残渣の溶媒抽出物を含有することを特徴とする抗炎症、抗かゆみ剤を提供するものである。また、本発明は、かかる抗炎症、抗かゆみ剤の有効成分として有用な、ある種のシソ科メンタ属植物の水蒸気蒸留残渣の溶媒抽出エキスも提供する。
【0005】
水蒸気蒸留に供するミント草としては、特に限定するものではなく、化粧料、医薬、食品用等の精油の採取に通常用いられる、例えば、ミズハッカ(Mentha aquatica L.)、セイヨウハッカ(Mentha piperita L.)、ペニロイアルハッカ(Mentha pulegium L.)、マルバハッカ(Mentha rotundifolia (L.) Huds.)、オランダハッカ(Mentha spicata L.)またはベルガモットハッカ(Mentha citrata (Ehrh.) Briq.)およびこれらの変種等が挙げられる。
また、ミント草の水蒸気蒸留も特に限定するものではなく、精油採取に採用されるものでよく、残渣はそのまま、あるいは乾燥等して用いることができる。
【0006】
本発明の有効成分は、かかるミント草の水蒸気蒸留残渣を溶媒抽出し、抽出液から溶媒を留去することによって得ることができる。
抽出溶媒としては、例えば、水、ベンゼン、ジエチルエーテル、クロロホルム、塩化メチレン、酢酸エチル、酢酸ブチル、アセトン、メタノール、エタノール、ブタノールおよび1,3−ブチレングリコールから選ばれる溶媒が挙げられ、これらは単独でも2種以上を混合してもよい。好ましい溶媒としては、水、メタノール、エタノールおよびこれらの混合溶媒が挙げられ、特に、エタノール抽出エキスおよびその精製物に強い抗炎症作用を有する成分が含有されるので、好ましい。
【0007】
抽出条件は任意に定めることができる。例えば、ミント草の水蒸気蒸留残渣を約1〜30倍程度の容量の抽出溶媒に常温または加熱下に浸漬するだけで抽出を行うことができる。抽出液は、濾過または遠心分離により固形物を除去した後、自体公知の適当な方法で抽出溶媒を留去し、そのまま使用してもよく、また、濃縮し、または乾燥して使用することができる。
所望により、上記の抽出液を活性炭で脱色したり、合成高分子吸着体等の樹脂処理等により精製してもよい。しかし、該有効成分の抗炎症、抗かゆみ作用は抽出物のままでも強く現れるので、色、臭い、安定性等の点で不都合がない限り、高度の精製は通常要しない。
【0008】
本発明の抗炎症、抗かゆみ剤における有効成分の配合量は、その製剤形、期待される炎症、かゆみ抑制効果の程度などによって異なるが、通常、製剤全量に基づいて、該成分を抽出物固形物換算で0.01〜10.0重量%、好ましくは0.1〜5.0重量%が適当である。
【0009】
本発明の抗炎症、抗かゆみ剤には、上記有効成分の他、所望により、基剤(例:ワセリン、流動パラフィン等)、増粘剤(例:カルボキシエチルセルロース、ヒアルロン酸等)、界面活性剤(例:ポリオキシエチレン硬化ヒマシ油、ラウリル硫酸ナトリウム等)、希釈剤(例:水、エタノール等)、香料等の製剤化用担体、賦形剤、添加剤のごとき補助成分を配合することができる。
本発明の抗炎症、抗かゆみ剤は、自体公知の方法により、軟膏、乳化剤、クリーム、ローション、パウダー、パック等の外用剤の製剤形とすることができ、化粧料、医薬、医薬部外品として炎症やかゆみの防止、抑制、創傷治癒、肌あれ防止、肌あれ改善に使用できる。

[Industrial application fields]
The present invention is an anti-inflammatory, anti-itch agent, more specifically, an anti-inflammatory, itching prevention, suppression, wound healing, comprising as an active ingredient a certain component obtained from a plant belonging to the genus Mentha (Mentha), The present invention relates to an external preparation useful as a cosmetic, medicine, or quasi-drug excellent in prevention of skin roughness and improvement of skin roughness.
[0002]
[Prior art and problems]
Diseases accompanied with itching include dry pruritus such as atopic dermatitis and senile pruritus. Such skin diseases cause mental distress and exacerbate symptoms by scratching the patient. Conventionally, various external preparations have been proposed to prevent or treat these skin diseases. Among these, in particular, taking a herbal medicine as a main component in consideration of a mild action on the skin, attention has been focused (for example, JP-A-1-319424). However, even herbal medicine components are not necessarily preferable for acting on the skin. From this point of view, there are no external preparations that can achieve satisfactory effects on diseases with itching so far.
In view of the current situation, the present inventors have conducted intensive research to provide a natural product-based anti-inflammatory and anti-itch agent that has a strong activity against inflammation and is also safe from the viewpoint of safety. Piled up.
[0003]
That is, itching is caused by applying a stimulus to the upper skin layer, and histamine is well known as a chemical substance that causes the irritation. Histamine is released into the tissue by degranulation from mast cells and causes itching, which is an initial reaction that causes inflammation (edited by Kubota, et al .: Modern Dermatology System 3C, Yasumasa Ishibashi, et al., Edited: Strong itchiness (Skin disease), the present inventors searched for various plant extracts using as an index the inhibitory action on histamine release (in vitro) and the anti-inflammatory action (in vivo) against an anti-inflammatory agent (compound 48/80). As a result, it has been found that there is a component having a strong anti-inflammatory action in the residue generated by steam distillation when collecting essential oil of a plant belonging to the genus Mentha (hereinafter referred to as mint grass), and the present invention is completed. It came to.
Mint leaves contain menthol as an essential oil component, and are widely used in mint flavors for cosmetic, dental and cooking purposes. Whole plants and oils have also been used as aromatic stimulants, wind drive, antiseptic and antispasmodic drugs. However, with respect to the portion excluding the essential oil component, that is, the steam distillation residue, a method for producing a deodorant substance (JP 59-6056-6058, JP 64-1145) and an oral composition (JP No. 62-155210) is known, and its physiological activity, anti-inflammatory and anti-itch action have not been reported yet.
[0004]
[Means for Solving the Problems]
The present invention provides an anti-inflammatory and anti-itch agent characterized by containing, as an active ingredient, a solvent extract of a steam distillation residue of a plant belonging to the genus Mentha, Mentha. The present invention also provides a solvent extract of a steam distillation residue of a certain Lamiaceae plant that is useful as an active ingredient of such anti-inflammatory and anti-itch agents.
[0005]
The mint grass to be subjected to steam distillation is not particularly limited, and is usually used for collecting essential oils for cosmetics, medicines, foods, etc., for example, mint mint (Mentha aquatica L.), mint mint (Mentha piperita L. ), Penilloy al mint (Mentha pulegium L.), Malba mint (Mentha rotundifolia (L.) Huds.), Dutch mint (Mentha spicata L.) or Bergamot mint (Mentha citrata (Ehrh.) Briq.) And their variants, etc. Is mentioned.
Further, steam distillation of mint grass is not particularly limited, and may be employed for collecting essential oil, and the residue can be used as it is or after drying.
[0006]
The active ingredient of the present invention can be obtained by solvent-extracting the steam distillation residue of mint grass and distilling off the solvent from the extract.
Examples of the extraction solvent include water, benzene, diethyl ether, chloroform, methylene chloride, ethyl acetate, butyl acetate, acetone, methanol, ethanol, butanol, and 1,3-butylene glycol. However, you may mix 2 or more types. Preferred examples of the solvent include water, methanol, ethanol and a mixed solvent thereof. In particular, the ethanol extract and its purified product contain a component having a strong anti-inflammatory action, which is preferred.
[0007]
The extraction conditions can be arbitrarily determined. For example, extraction can be performed simply by immersing a steam distillation residue of mint grass in an extraction solvent having a volume of about 1 to 30 times at room temperature or under heating. The extraction liquid may be used as it is after removing the solid matter by filtration or centrifugation, and the extraction solvent may be distilled off by an appropriate method known per se, or it may be used after being concentrated or dried. it can.
If desired, the above extract may be decolorized with activated carbon or purified by a resin treatment such as a synthetic polymer adsorbent. However, since the anti-inflammatory and anti-itching action of the active ingredient appears strongly even with the extract, high-level purification is usually not required unless there are inconveniences in terms of color, odor, stability and the like.
[0008]
The compounding amount of the active ingredient in the anti-inflammatory and anti-itch agent of the present invention varies depending on the preparation form, expected inflammation, the level of the itching-inhibiting effect, etc. 0.01 to 10.0% by weight, preferably 0.1 to 5.0% by weight in terms of product is appropriate.
[0009]
In addition to the above active ingredients, the anti-inflammatory and anti-itch agents of the present invention include a base (eg, petroleum jelly, liquid paraffin, etc.), a thickener (eg: carboxyethyl cellulose, hyaluronic acid, etc.), a surfactant, as desired. (Examples: polyoxyethylene hydrogenated castor oil, sodium lauryl sulfate, etc.), diluents (eg, water, ethanol, etc.), carriers for formulation of fragrances, excipients, additives such as additives, etc. it can.
The anti-inflammatory and anti-itch agent of the present invention can be made into a preparation form of external preparations such as ointments, emulsifiers, creams, lotions, powders, packs, etc. by a method known per se. Cosmetics, pharmaceuticals, quasi drugs It can be used to prevent inflammation, itching, suppress wound, heal, prevent skin roughness and improve skin roughness.
