外来植物である孟宗竹は、1950年代頃までは竹材や筍を得るために管理された竹林で栽培されていた。しかしながら、近年は竹林業が経済的に成立しなくなり、各地で竹林が放置されるようになった。孟宗竹は繁殖力が異常に強いため、放置された竹林では、竹の繁殖域が無秩序に周囲に広がり、既存の植生を破壊するいわゆる竹害が問題となっている。 The exotic plant, Munetake Bamboo, was cultivated in bamboo forests managed to obtain bamboo and bamboo until the 1950s. However, in recent years, bamboo forestry has not been established economically, and bamboo forests have been neglected in various places. Since the reproductive power of Somune bamboo is unusually strong, in the abandoned bamboo forests, the so-called bamboo damage that destroys the existing vegetation is a problem because the bamboo breeding area spreads out randomly.
一方、竹害の問題に対し、竹を有効利用するための研究が進められている。例えば、竹を常圧過熱水蒸気で処理して発生する蒸気を凝縮して得られる竹の過加熱水蒸気抽出物(以下、竹SHS(Super-Heated Stream)抽出物という)が、食中毒原因菌選択制抗菌剤として提案されている(特許文献1)。 On the other hand, research on the effective use of bamboo is underway for the problem of bamboo damage. For example, bamboo superheated steam extract (hereinafter referred to as bamboo SHS (Super-Heated Stream) extract) obtained by condensing steam generated by treating bamboo with normal-pressure superheated steam is a food poisoning-causing bacteria selection system. It has been proposed as an antibacterial agent (Patent Document 1).
特許文献1に記載の竹SHS抽出物も含めて、竹抽出物に抗菌作用があることや低分子量の有機酸(ギ酸、酢酸、コハク酸、リンゴ酸など)が含まれることが知られているが、有機酸の物性から、竹抽出物を外用剤として皮膚疾患治療や美容の目的に利用する場合、皮膚刺激が懸念される。

(4-1) Isolation of hamster sebaceous gland cells The left and right auricles of a golden hamster (male, 5 weeks old) were excised and immersed in DMEM supplemented with penicillin G (100 units / mL) and streptomycin (100 μg / mL). After standing at 4 ° C. for 1 hour or longer, it was washed with a phosphate buffered saline (PBS (−)). The hair around the auricle was cut, chopped to about 5 × 5 mm, and left in a 2.4 units / mL displace solution at 4 ° C. for 13.5 hours. After the enzyme treatment, the epidermis is peeled off from the auricle with tweezers, and the dermis including the sebaceous glands is sebaceous cell culture solution (SGM) [DMEM / F12 / 6% (v / v) FBS / 2% (v / v) human serum / 0.68 mM L-glutamine / penicillin (100 units / mL) / sulfate streptomycin (100 μg / mL)], and sebaceous glands were isolated under a stereomicroscope.
(4-2)ハムスター脂腺細胞の皮脂産生に対する竹SHS抽出物の作用
継代培養したハムスター脂腺細胞(p=5)を96well plate (IWAKI製)に1.0×104cells/wellの細胞数で播種した。この場合、ハムスター脂腺細胞を未分画の竹SHS抽出物(0.0003%、0.01%、0.1%及び1%)、及び竹SHS抽出物のHPLC分画のF1D、F1W、F2、F3、F4、F5、F6、F7、F8及びF9(0.0003%、0.01%、及び1%)でそれぞれ処理し、9日間培養した。培養後、リン酸緩衝液(PBS(−))にて細胞を洗浄し、4%パラホルムアルデヒドにて固定し、細胞標本を得た。

Sowing. In this case, hamster sebaceous gland cells were separated from unfractionated bamboo SHS extract (0.0003%, 0.01%, 0.1% and 1%), and F1D, F1W, F2 of HPLC fractions of bamboo SHS extract. , F3, F4, F5, F6, F7, F8 and F9 (0.0003%, 0.01% and 1%), respectively, and cultured for 9 days. After culturing, the cells were washed with a phosphate buffer (PBS (−)) and fixed with 4% paraformaldehyde to obtain a cell specimen.
皮脂産生能に対する竹SHS抽出液の影響を評価するため、得られた細胞標本をoil red O染色法により脂肪滴を染色した。また、対照として、DHTや竹SHS抽出物を添加せずに作製した細胞標本(Ctl)、DHTの存在下(濃度10μM)で竹SHS抽出物を添加せずに作製した細胞標本(DHT)、又は皮脂産生促進作用が知られているインスリン(Ins)の存在下(濃度10μM)で作製した細胞標本についても同様に染色した。
In order to evaluate the effect of bamboo SHS extract on sebum production ability, the obtained cell specimen was stained with fat red O staining method. In addition, as a control, a cell specimen (Dtl) prepared without adding DHT or bamboo SHS extract, a cell specimen (DHT) prepared without adding bamboo SHS extract in the presence of DHT (
ここで、Oil red O染色液は、0.3%(w/v)oil red O を含む isopropanol溶液と精製水を3:2(v:v)で混合し、密閉式超音波細胞破砕装置(コスモ・バイオ株式会社製)により15分間超音波処理を行い、10分間室温に放置し、ろ過した上清である。 Here, the Oil red O staining solution is prepared by mixing an isopropanol solution containing 0.3% (w / v) oil red O and purified water at a ratio of 3: 2 (v: v), and a sealed ultrasonic cell disruption device ( The supernatant was sonicated for 15 minutes by Cosmo Bio Co., Ltd., left at room temperature for 10 minutes, and filtered.
この染色法では、固定した細胞標本にoil red O 染色液を加えて37℃で15分間染色した。 In this staining method, oil red O staining solution was added to the fixed cell specimen and stained at 37 ° C. for 15 minutes.
染色後、細胞をリン酸緩衝液(PBS(−))にて洗浄し、光学顕微鏡(オリンパス株式会社製)により脂肪滴形成を観察した。この観察写真を「竹SHS抽出物(画分)」として図3A、図3B、図3C及び図3Dに示す。 After staining, the cells were washed with a phosphate buffer (PBS (−)), and lipid droplet formation was observed with an optical microscope (Olympus Corporation). This observation photograph is shown in FIG. 3A, FIG. 3B, FIG. 3C, and FIG. 3D as a “bamboo SHS extract (fraction)”.
また、皮脂の主成分であるトリアシルグリセロール(TG)を定量するため、DHTや竹SHS抽出物を添加しない細胞(Ctl)、DHTの存在下(濃度10μM)で竹SHS抽出物を添加せずに処理した細胞(DHT)、皮脂産生抑制作用が知られているレチノイン酸を処理した細胞(RA)(濃度1nM)、皮脂産生促進作用が知られているインスリンを処理した細胞(Ins)(濃度10μM)、DHT存在下でRAを処理した細胞(DHT+RA)、DHT存在下で竹SHS抽出物を処理した細胞(DHT+竹SHS抽出物0.1%又は1%)をそれぞれPBS(−)で2回洗浄し、0.25% (w/v) trypsin/0.02% (w/v) EDTA/PBS(−)溶液を用いて回収した。得られた細胞懸濁液を氷冷下、密閉式超音波細胞破砕装置(コスモ・バイオ株式会社製)により超音波処理を行い、細胞を破砕した。この細胞内のTG量をアクアオートカイノスTG−II試薬(株式会社カイノス製)を用いて次の方法で測定した。すなわち、上記で調製した細胞懸濁液試料(50μL)に反応試液R−1(90μL)を添加し、37℃で10分間反応させた後、直ちに反応試液R−2(30μL)を添加し、さらに37℃で10分間反応させた。反応終了後、595nmにおける吸光度をマイクロプレートリーダーにて測定した。この吸光度からTG量を、同様に実施したトリオレイン標準液(200mg/dL)の吸光度に基づいて算出した。一方、細胞中のDNA量を3,5−ジアミノ安息香酸二塩酸塩(DABA)法を用いて測定し、DNA1μgあたりの皮脂量(TG/DNA)を求め、このTG/DNAのコントロールに対する比を求めた。結果を図4に示す。
In addition, in order to quantify triacylglycerol (TG), which is the main component of sebum, cells without the addition of DHT or bamboo SHS extract (Ctl), without the addition of bamboo SHS extract in the presence of DHT (
図3A〜図3D及び図4から、未分画の竹SHS抽出物には、その濃度依存的にDHTにより誘導した皮脂産生を抑制する作用が認められ、竹SHS抽出物の濃度が1%であると外観観察から細胞死が疑われた。また、竹SHS抽出物のF1Dには皮脂産生に対して強い抑制作用が認められた。しかしながら、竹SHS抽出物のF2〜F5には細胞毒性が認められず、F6〜F8には皮脂産生の促進作用が認められた。したがって、F6〜F8を含む画分、即ち、リテンションタイムが32分以上42分以下の画分は、皮脂産生促進剤の有効成分となることがわかる。また、観察された脂肪滴を蓄積する細胞数と各画分の濃度との関係から、この有効成分の適正濃度は、画分濃度として1%未満であることがわかる。 From FIG. 3A to FIG. 3D and FIG. 4, the unfractionated bamboo SHS extract has an effect of suppressing sebum production induced by DHT in a concentration-dependent manner, and the concentration of the bamboo SHS extract is 1%. In some cases, cell death was suspected from appearance observation. In addition, F1D of bamboo SHS extract showed a strong inhibitory effect on sebum production. However, no cytotoxicity was observed in F2 to F5 of the bamboo SHS extract, and a sebum production promoting effect was observed in F6 to F8. Therefore, it can be seen that the fraction containing F6 to F8, that is, the fraction having a retention time of 32 minutes or more and 42 minutes or less is an active ingredient of the sebum production promoter. In addition, from the relationship between the observed number of cells that accumulate lipid droplets and the concentration of each fraction, it is understood that the appropriate concentration of this active ingredient is less than 1% as the fraction concentration.
