Description

本発明は皮膚ガス成分の量を規格化する方法に関し、特に任意の皮膚ガス成分の変化を高精度に評価することのできる皮膚ガス成分の量を規格化する方法に関する。   The present invention relates to a method for normalizing the amount of a skin gas component, and more particularly to a method for normalizing the amount of a skin gas component that can accurately evaluate changes in any skin gas component.

人の体臭には皮膚表面で皮脂が酸化するなどで発生するものと、体内由来(血中、細胞由来)で皮膚を通って放出されてくる炭化水素、アルコールなどのさまざまなガスが混ざっている。皮膚を通って放出されるこれらのガスは皮膚ガスと呼ばれ、食事、体調、心理的な要因に左右され、体内の状態を表していると言われている。   Human body odor is a mixture of various gases such as hydrocarbons and alcohols that are generated by the oxidation of sebum on the skin surface, and hydrocarbons and alcohol released from the body (derived from blood and cells) through the skin. . These gases released through the skin are called skin gases and are said to represent the state of the body depending on diet, physical condition and psychological factors.

近年、皮膚ガスに含まれる成分の種類や濃度を観測することにより、健康状態など、人の体内の状態を診断するために、皮膚ガス中の成分について調査研究が行われている。例えば、糖尿病患者の皮膚表面からアセトンが放出されていることが知られている(非特許文献1)。
好ましくないとされている臭いも存在する。例えば、中年以降の人に特有の臭い、いわゆる加齢臭は、ノネナールが主成分であることが知られている。
In recent years, in order to diagnose the state of a human body, such as a health condition, by observing the types and concentrations of the components contained in the skin gas, research on the components in the skin gas has been conducted. For example, it is known that acetone is released from the skin surface of a diabetic patient (Non-Patent Document 1).
There are also odors that are considered undesirable. For example, it is known that nonenal is a main component of the so-called aging odor peculiar to people after middle age.

そこで、好ましくない臭いの皮膚ガスを抑制する製剤の開発が進められている。例えば、食用担子菌類の有機酸含有親水性溶媒抽出物を有効成分として含有する加齢臭抑制用組成物が知られている(特許文献1)。このような製剤を開発する際には、製剤投与前後の皮膚ガスを採取し、皮膚ガス成分の変化を分析することが行われている。
しかし、皮膚ガスは、外気温湿度に大きく影響されることなどから、定量比較がしづらく、このような製剤の開発は困難であった。
Therefore, development of a preparation that suppresses an unpleasant odor skin gas is underway. For example, a composition for suppressing aging odor containing an organic acid-containing hydrophilic solvent extract of edible basidiomycetes as an active ingredient is known (Patent Document 1). In developing such a preparation, skin gas before and after administration of the preparation is collected and changes in skin gas components are analyzed.
However, since skin gas is greatly affected by outside temperature and humidity, it is difficult to make a quantitative comparison, and it has been difficult to develop such a preparation.

It is characterized by normalizing the quantity.

皮膚ガス成分の採取方法としては、公知の方法を用いることができる。
例えば、皮膚ガス採取装置(非吸着かつ非透過性のガスバリア素材の袋など)を手首から先(手および手首)に装着し、クリーンガス(N)を充填し、30分程度放置後に採取する方法、無臭のTシャツを3日程度着用後に採取する方法などが挙げられる。
前者では、汗腺由来の成分、すなわち血中成分を主に反映するのに対し、後者では、汗と皮脂由来成分が混在する。
本発明にかかる方法では、皮膚ガス採取装置を手首から先に装着し、クリーンガス(N)を充填し、30分程度放置後に採取する方法を用いることが好ましい。
また、皮膚ガスの採取は、恒温恒湿室で行うことが好ましい。
As a method for collecting skin gas components, a known method can be used.
For example, a skin gas sampling device (such as a non-adsorbing and non-permeable gas barrier material bag) is attached from the wrist to the tip (hand and wrist), filled with clean gas (N 2 ), and collected after being left for about 30 minutes. And a method of collecting an odorless T-shirt after wearing it for about 3 days.
The former mainly reflects sweat gland-derived components, that is, blood components, while the latter contains sweat and sebum-derived components.
In the method according to the present invention, it is preferable to use a method in which a skin gas sampling device is attached first from the wrist, filled with clean gas (N 2 ), and collected after being left for about 30 minutes.
Further, it is preferable to collect the skin gas in a constant temperature and humidity chamber.

皮膚ガス成分を定量する手段としては、公知のガス分析装置を用いることができるが、GC/MS、すなわちガスクロマトグラフ−質量分析計を用いることが好ましい。   As a means for quantifying the skin gas component, a known gas analyzer can be used, but it is preferable to use GC / MS, that is, a gas chromatograph-mass spectrometer.

例えば、GC/MSによりガスクロマトグラムを測定後、目的とする皮膚ガス成分のピーク面積から、定量を行う。
そして、皮膚ガス成分中のノナナールの量で目的とする皮膚ガス成分の量を規格化する(すなわち、ノナナールの量で除される)ことで、外気温湿度などの影響による分析値のバラツキを受けることなく、任意の皮膚ガス成分を高精度で定量することができる。
For example, the gas chromatogram is measured by GC / MS, and then quantified from the peak area of the target skin gas component.
And, by standardizing the amount of the target skin gas component by the amount of nonanal in the skin gas component (that is, divided by the amount of nonanal), the analysis value varies due to the influence of outside temperature and humidity. Therefore, any skin gas component can be quantified with high accuracy.

また、本発明にかかる対象物の変化を比較するための皮膚ガス発生量の評価方法は、GC/MSなどのガス分析装置を用いて皮膚ガス成分を定量し、
ノナナールで規格化することを特徴とする。
また、本発明にかかる対象物の変化を比較するための皮膚ガス発生量の評価方法は、同一人物の皮膚ガス成分の評価方法であることが好適である。
皮膚ガス成分は、同一人物であっても、外気温湿度や心身の状態等の影響により、激しく変動し、対象物の定量比較を行うことは困難であった。しかし、本発明の評価方法を用いることにより、外気温湿度や心身の状態等の影響されずに、容易に対象物の定量比較を行うことが可能である。
In addition, the skin gas generation amount evaluation method for comparing changes in the object according to the present invention quantifies skin gas components using a gas analyzer such as GC / MS,
It is standardized by Nonanal.
In addition, the skin gas generation amount evaluation method for comparing changes in the object according to the present invention is preferably the same person skin gas component evaluation method.
Even in the same person, the skin gas component fluctuates violently due to the influence of the outside air temperature humidity and the state of mind and body, and it is difficult to quantitatively compare the objects. However, by using the evaluation method of the present invention, it is possible to easily perform quantitative comparison of objects without being affected by the outside air temperature humidity and the state of mind and body.

<試験例1>
65歳から74歳の女性パネル20名に手を石鹸で洗ってもらった後、皮膚ガス採取装置(非吸着かつ非透過性のガスバリア素材の袋)を手首から先(手および手首)に装着し、クリーンガス(N)を充填し、20分放置後に皮膚ガスを採取した。そして、ガス分析装置(GC/MS)を用いて、採取した皮膚ガスのガスクロマトグラムを測定した。還元型コエンザイムQ10(ソフトカプセル、100mg/日)またはプラセボを4週間(毎日)連用投与後、同様に皮膚ガスを採取し、ガスクロマトグラムを測定した。なお、10名のパネルには、プラセボ連用投与試験の後に還元型コエンザイムQ10連用投与試験を行ってもらい、もう10名のパネルには、還元型コエンザイムQ10連用投与試験の後にプラセボ連用投与試験を行ってもらった。
なお、GC/MSは、5977 GC/MSシステム(Agilent社製)を用いた。
<Test Example 1>
After 20 female panels aged 65 to 74 wash their hands with soap, wear a skin gas sampling device (a bag of non-adsorbing and non-permeable gas barrier material) from the wrist to the tip (hand and wrist). After filling with clean gas (N 2 ) and leaving for 20 minutes, the skin gas was collected. And the gas chromatogram of the extract | collected skin gas was measured using the gas analyzer (GC / MS). After continuous administration of reduced coenzyme Q10 (soft capsule, 100 mg / day) or placebo for 4 weeks (daily), skin gas was collected in the same manner, and gas chromatogram was measured. The 10-person panel was given a reduced coenzyme Q10 continuous administration test after the placebo continuous administration test, and the other 10 panel was followed by a placebo continuous administration test after the reduced coenzyme Q10 continuous administration test. I got it.
In addition, 5977 GC / MS system (made by Agilent) was used for GC / MS.

ガスクロマトグラムより、4週間連用投与前のパネルから、ノネナールが検出されたことがわかった。ノネナールは、加齢臭の主成分であると言われている。これまでノネナールは、皮膚表面にある皮脂の酸化によって発生していると考えられていたが、体内から検出されることがわかった。   From the gas chromatogram, it was found that nonenal was detected from the panel before continuous administration for 4 weeks. Nonenal is said to be the main component of aging odor. Until now, nonenal was thought to be generated by the oxidation of sebum on the skin surface, but it was found to be detected in the body.

図1に、ガスクロマトグラムのピーク面積より定量した還元型コエンザイムQ10;プラセボ4週間連用投与前後におけるノネナール量(それぞれアクティブ;プラセボ)の変化を示す。
図1より、還元型コエンザイムQ10を連用投与することにより、皮膚ガス中のノネナールの有意な減少が認められた。
しかしながら、本試験は冬に行われたものであり、部屋の温度が低くなった影響で、全体としての皮膚ガス成分が少ないため、還元型コエンザイムQ10の連用によるノネナール抑制効果は少ないようにも見える。
FIG. 1 shows changes in the amount of reduced coenzyme Q10 (quantitative active, placebo) before and after continuous administration of reduced coenzyme Q10; placebo for 4 weeks determined from the peak area of the gas chromatogram.
From FIG. 1, a significant decrease in nonenal in the skin gas was observed by continuous administration of reduced coenzyme Q10.
However, this test was conducted in winter, and due to the effect of the lower room temperature, the skin gas component as a whole is small, so it seems that the inhibitory effect of reduced coenzyme Q10 on the continuous use of nonenal is small. .

<試験例2>
そこで本発明者らは、20代〜60代までの男女複数のパネルについて、試験例1と同様に皮膚ガス成分の採取およびGC/MSを用いた測定を行い、いくつかの他の皮膚ガス成分の定量結果を検討した。
<Test Example 2>
Therefore, the present inventors performed collection of skin gas components and measurement using GC / MS in the same manner as in Test Example 1 for a plurality of male and female panels from the 20s to 60s, and some other skin gas components. The quantitative results were investigated.

その結果、皮膚ガス成分の中には、検出される人と検出されない人がいる成分が存在することがわかった(例えばオクタナール)。しかし、皮膚ガス成分のうち、リモネンおよびノナナールは、全ての人から検出された。ここで、リモネンは、柑橘(レモン)様の臭い成分であって、ノナナールは、花や果実様の臭い成分である。
図2に、被験者の年代および男女別にリモネンとノナナールを定量した結果を示す((A)リモネン、(B)ノナナール)。
As a result, it was found that there are components in the skin gas component that include a detected person and a non-detected person (for example, octanal). However, among the skin gas components, limonene and nonanal were detected from all persons. Here, limonene is a citrus (lemon) -like odor component, and nonanal is a flower or fruit-like odor component.
FIG. 2 shows the results of quantifying limonene and nonanal for each subject's age and gender ((A) limonene, (B) nonanal).

図2より、リモネンより、ノナナールの方が、個人による皮膚ガス量の差が小さいことが明らかになった。   From FIG. 2, it became clear that nonanal had a smaller difference in individual skin gas amounts than limonene.

<試験例3>
次に、20代〜50代の男性4名(各年代1名ずつ)と、20代〜40代の女性6名(各年代2名ずつ)に、2〜7日間、皮膚ガス成分の採取およびGC/MSを用いた測定を行い、リモネンとノナナールの定量結果を検証した。
なお、皮膚ガス成分は、28℃、50%にコントロールされた部屋で30分安静の後、皮膚ガス採取装置に片手あたり180mL窒素を充填し、15分後に150mL採取した。
男性、女性の結果を、それぞれ図3、図4に示す((A)リモネン、(B)ノナナール)。
<Test Example 3>
Next, collection of skin gas components for 4 to 7 men in their 20s to 50s (one in each age) and 6 women in their 20s to 40s (2 in each age) The measurement using GC / MS was performed, and the quantitative results of limonene and nonanal were verified.
The skin gas component was rested for 30 minutes in a room controlled at 28 ° C. and 50%, and then the skin gas collection device was filled with 180 mL nitrogen per hand, and 150 mL was collected after 15 minutes.
The results for males and females are shown in FIGS. 3 and 4, respectively ((A) limonene, (B) nonanal).

図3および図4によると、リモネンより、ノナナールの方が、個人による皮膚ガス量の差が小さいことが再確認できた。
また、同一個人内での日間変動も、ノナナールの方が小さいことが明らかになった。
したがって、皮膚ガス成分中のノナナールの量は、個人固有の値であって、同じ採取条件であれば、個人内で安定な皮膚ガス成分であることがわかった。
According to FIG. 3 and FIG. 4, it was reconfirmed that nonanal had a smaller difference in individual skin gas amount than limonene.
In addition, it became clear that nonanal also had smaller daily fluctuations within the same individual.
Therefore, it was found that the amount of nonanal in the skin gas component is a value unique to the individual and is a stable skin gas component within the individual under the same collection conditions.

そこで、本発明者らは、ノナナールの量で、目的とする皮膚ガス成分の量を規格化できるのではないかという仮定の下、試験例1で測定したガスクロマトグラムについて再検討した。
プラセボおよび還元型コエンザイムQ10の投与前後におけるノネナール、ノナナールの定量結果、ノネナール量/ノナナール量および標準偏差を算出した結果を、それぞれ表1および表2に示す。また、4週間連用投与前後の差を示した結果を表5に示す。
また、投与前後における定量されたノネナールの量を、ノナナールの量で規格化した(ノナナールの量で除された)結果を図5に示す。なお、図5の投与後の結果は、投与前の平均値を1として算出した場合の平均値を示してある。
Therefore, the present inventors reexamined the gas chromatogram measured in Test Example 1 under the assumption that the amount of the target skin gas component can be normalized by the amount of nonanal.
Tables 1 and 2 show the results of quantification of nonenal and nonanal before and after administration of placebo and reduced coenzyme Q10, and the calculated amount of nonenal / nonanal and standard deviation, respectively. Table 5 shows the results showing the difference before and after continuous administration for 4 weeks.
In addition, FIG. 5 shows the results of normalizing the amount of nonenal determined before and after administration with the amount of nonanal (divided by the amount of nonanal). In addition, the result after administration in FIG. 5 shows the average value when the average value before administration is calculated as 1.

表3より、ノネナールをノナナールで規格化しない場合、データのバラツキが大きい一方で、ノネナールをノナナールで規格化すると、標準偏差が小さくなることがわかった。
したがって、本発明にかかる皮膚ガス成分の量を規格化する方法は、GC/MSなどのガス分析装置を用いて皮膚ガス成分を定量し、定量されたノナナールの量で、定量された前記皮膚ガス成分の量を規格化することを特徴とする。本方法を用いることにより、皮膚ガス成分を高精度に評価することができる。
Table 3 shows that when nonenal is not normalized with nonanal, there is a large variation in data, whereas when nornal is normalized with nonanal, the standard deviation becomes small.
Therefore, the method for normalizing the amount of skin gas component according to the present invention is to quantify the skin gas component using a gas analyzer such as GC / MS, and determine the amount of nonanal as determined. It is characterized by normalizing the amount of components. By using this method, the skin gas component can be evaluated with high accuracy.

また、図5より、ノネナールをノナナールで規格化すると、還元型コエンザイムQ10を連用した場合のみノネナールを有意に減少することをわかった。
これまで、皮膚ガス成分の抑制効果を、官能評価以外で示すことは困難であったが、本発明にかかる皮膚ガス成分の量を規格化する方法を用いることで、測定値として示すことができる。また、本発明にかかる皮膚ガス成分の量を規格化する方法によれば、任意の皮膚ガス成分の変化を高精度に評価することができる。
Further, FIG. 5 shows that when nonenal is normalized with nonanal, nonenal is significantly reduced only when reduced coenzyme Q10 is used continuously.
Until now, it has been difficult to show the inhibitory effect of skin gas components except for sensory evaluation, but it can be shown as a measured value by using the method for normalizing the amount of skin gas components according to the present invention. . Moreover, according to the method for normalizing the amount of skin gas component according to the present invention, it is possible to evaluate a change in any skin gas component with high accuracy.
