超臨界抽出装置にザクロソウ属植物を投入し、40℃において15MPaの気圧下で二酸化炭素の超臨界流体を用いて抽出した。抽出物を回収し、ザクロソウ属植物の抽出物を得た。
[Production Example 4]
The plant of the genus Pomegranate was introduced into a supercritical extraction apparatus, and extracted using a supercritical fluid of carbon dioxide at 40 ° C. under a pressure of 15 MPa. The extract was collected to obtain an extract of the plant of the genus Pomegranate.

まず、ザクロソウ属植物の抽出物の細胞賦活作用について示す。試料には、ザクロソウの全草を製造例1により抽出したものを試料として評価を行った。   First, it shows about the cell activation effect of the extract of a genus Pomegranate. The sample was evaluated by extracting the whole plant of pomegranate according to Production Example 1 as a sample.

評価は、以下の手順で行った。正常ヒト真皮線維芽細胞を1ウェル当たり2.0×10個となるように96穴マイクロプレートに播種した。播種培地には、ダルベッコ改変イーグル培地(DMEM)に1%のウシ胎児血清を添加したものを用いた。24時間培養後、任意の濃度の試料を添加した試験培地に交換し、さらに48時間培養した。次いで3−(4,5−ジメチル−2−チアゾリル)−2,5−ジフェニルテトラゾリウムブロミド(MTT)を400μg/mL含有する培地に交換して2時間培養し、テトラゾリウム環の開環により生じるフォルマザンを2−プロパノールにて抽出し、マイクロプレートリーダーにて550nmの吸光度を測定した。同時に濁度として650nmにおける吸光度を測定し、両測定値の差により細胞賦活作用を評価した。評価結果を、試料無添加のブランクにおける細胞賦活作用を100とした相対値にて表1に示す。なお、表中の*及び**は、t検定における有意確率P値に対し、有意確率1%未満(P<0.05)を*で有意確率1%未満(P<0.01)を**で表したものである。 The evaluation was performed according to the following procedure. Normal human dermal fibroblasts were seeded in a 96-well microplate at 2.0 × 10 4 cells per well. The seeding medium used was Dulbecco's modified Eagle medium (DMEM) supplemented with 1% fetal bovine serum. After culturing for 24 hours, the culture medium was replaced with a test medium to which a sample having an arbitrary concentration was added, and further cultured for 48 hours. Next, the medium containing 400 μg / mL of 3- (4,5-dimethyl-2-thiazolyl) -2,5-diphenyltetrazolium bromide (MTT) was exchanged and cultured for 2 hours. Formazan generated by the opening of the tetrazolium ring was removed. Extraction was performed with 2-propanol, and absorbance at 550 nm was measured with a microplate reader. At the same time, the absorbance at 650 nm was measured as turbidity, and the cell activation effect was evaluated by the difference between the two measured values. The evaluation results are shown in Table 1 as relative values with the cell activation effect in the blank with no sample as 100. In the table, * and ** indicate a significance probability of less than 1% (P <0.05) and a significance probability of less than 1% (P <0.01), respectively, with respect to the significance P value in the t test. This is indicated by *.

From this, it became clear that the extract of the plant of the genus Pomegranate has an excellent cell activation effect.

次に、ザクロソウ属植物の抽出物の抗酸化作用について示す。試料には、ザクロソウの全草を製造例1により抽出したものを試料として評価を行った。   Next, the antioxidant effect of the extract of the genus Pomegranate is shown. The sample was evaluated by extracting the whole plant of pomegranate according to Production Example 1 as a sample.

評価は、以下の手順で行った。50重量%エタノール水溶液にて任意の濃度に希釈した試料を96穴マイクロプレートに100μL添加した。次に、0.2mMの濃度になるようにエタノールにて調製した1、1−ジフェニル−2−ピクリルヒドラジル(DPPH)溶液を96穴マイクロプレートに100μL添加した。攪拌しながら暗所に放置し、24時間後に516nmの吸光度を測定した。試料が無添加のブランクの吸光度を(A)、試料を添加したときの吸光度を(B)としたとき、式(1)の値をラジカル消去率とした。評価結果を表2に示した。
式(1) {1−(B)/(A)}×100(%)
The evaluation was performed according to the following procedure. 100 μL of a sample diluted to an arbitrary concentration with a 50 wt% aqueous ethanol solution was added to a 96-well microplate. Next, 100 μL of a 1,1-diphenyl-2-picrylhydrazyl (DPPH) solution prepared with ethanol to a concentration of 0.2 mM was added to a 96-well microplate. The mixture was left in the dark with stirring, and the absorbance at 516 nm was measured after 24 hours. When the absorbance of the blank with no sample added was (A) and the absorbance when the sample was added was (B), the value of formula (1) was defined as the radical elimination rate. The evaluation results are shown in Table 2.

各試料について、肌荒れ症状が顕著に認められる30〜50才代の乾燥肌の女性パネラー20名をそれぞれ一群とし、ブラインドにて1週間使用させ、使用前後の皮膚状態の変化を観察して評価した。皮膚症状の指標として、乾燥による肌荒れについて、「改善」、「やや改善」、「変化なし」の三段階で評価し、表4に各評価を得たパネラー数にて示した。   For each sample, 20 female panelists with dry skin in their 30s to 50s whose skin symptom was remarkably recognized were grouped and used for one week blindly, and the skin condition before and after use was observed and evaluated. . As an index of skin symptoms, rough skin due to dryness was evaluated in three stages of “improvement”, “slight improvement”, and “no change”, and Table 4 shows the number of panelists that obtained each evaluation.

表4より、ザクロソウ属植物の抽出物を含有しない比較例使用群においては、7割以上のパネラーに改善は認められなかったが、ザクロソウ属植物の抽出物を配合した実施例使用群においては、7割以上のパネラーに明確な肌荒れの改善が認められた。このことから、ザクロソウ属植物の抽出物は優れた保湿効果を有することが明らかとなった。   From Table 4, in the comparative example use group not containing the extract of the genus Pomegranate plant, improvement was not recognized in 70% or more of the panelers, but in the example use group containing the extract of the genus Pomegranate, More than 70% of panelists showed a clear improvement in rough skin. From this, it became clear that the extract of the plant of the genus Pomegranate has an excellent moisturizing effect.
