  Since the extract of a specific plant provided by the present invention contains a large amount of mucus polysaccharides and the like, it has a high skin moisturizing action / protective action when used as a raw material for cosmetics. This extract also has a strong effect of improving and smoothing damaged skin. Furthermore, this extract suppresses excessive secretion of skin bacteria and skin fat, and is effective in preventing and improving acne and pimples. Therefore, the cosmetic containing the extract obtained by the method of the present invention can prevent rough skin, wrinkles, stains, hair rustling, hair loss and the like, and improves damaged skin and hair from the essence. There is an effect. As specific plants, there are lily family plants, and particularly, black lily, katakuri, kisge leaf and / or bulb extracts are highly useful for the skin and body.

  Embodiments of the present invention will be described below. In the present invention, black lily, katsuri, kisge leaves and / or bulbs are targeted. These will be described below. First, a method for extracting an extract from the leaves and / or bulbs of the specific plant will be described. FIG. 1 is a flowchart showing an extract extraction method when black lily is used as a specific plant.

  As shown in the flowchart of FIG. 1, first, the black lily leaves and bulbs are washed with water. Cleaning is generally performed separately for the leaves and bulbs from the viewpoint of efficiency, but since there is no necessity to separate them, the leaves and bulbs may be washed together. When washing is completed, the leaves and bulbs are put into a mixer used for normal grinding and pulverized. In this case, pulverization is performed for 10 to 30 minutes per kg of leaves and / or bulbs. When the pulverization is completed, the process proceeds to the extraction step. Here, 50 to 1000 ml of extraction solvent is used per 200 g of the pulverized product, and mixed extraction is performed with a stirrer. The extraction time is 15 minutes or longer. Here, as the extraction solvent, a mixture (or any one) of 1.3 butylene glycol and water can be used. The mixing ratio of 1.3 butylene glycol and water can be 100: 0 to 0: 100. As other extraction solvents, it is possible to use a mixture of ethanol and water (mixing ratio 100: 0 to 10:90), a mixture of sucrose and water (mixing ratio 75:25 to 10:90), and the like. it can.

  As an extraction method, a supercritical extraction method using carbon dioxide gas can be applied in addition to the mixed extraction method described above. In this case, the temperature is room temperature or warming (30 ° C. to 100 ° C .: preferably 30 ° C. to 50 ° C.), and can be normal pressure or under pressure. The extraction time by the supercritical extraction method is 10 minutes to 200 hours per 200 g. Here, the reason for setting it to 10 minutes or more is that extraction of 90% or more is performed in 10 minutes.

  When the extraction is completed, the mixed liquid is filtered. The filtration membrane used for filtration is 50-300 mesh. As the filtration method, any of natural filtration, suction filtration, and pressure filtration can be used, and the filtration time is set each time according to the amount of the mixed solution. The filtrate obtained as a result of filtration is then concentrated if necessary. For concentration, vacuum distillation can be used. When the concentration step is completed, deodorization and decolorization purification are performed. In this process, a stainless steel tank or the like is used, and adsorption purification is performed by activated carbon treatment. The amount of activated carbon is about 1 to 10 g per 200 g of concentrated filtrate.

  Thereafter, further filtration is performed. The filtration membrane used for filtration is 50-300 mesh. As a filtration method, any of natural filtration, suction filtration, and pressure filtration can be used, and what is obtained by completing the filtration is black lily leaf and / or bulb extract. Cosmetics can be produced. Although FIG. 1 shows the extract extraction method in the case of black lily, it is almost the same in the case of other plants, that is, in the case of katakuri and kisge.

  Next, examples of cosmetics using the extract extracted by the above method will be described in relation to comparative examples. Table 1 shows a comparison between a lotion using an extract obtained from a black lily bulb (Example 1) and a lotion using an extract obtained from a katsuri bulb (Example 2) with two comparative examples. It is. Example 1 and Example 2 have higher moisture retention and less stickiness than the two comparative examples, and are obtained as evaluation results by professional panel sensory evaluation.

  Table 2 compares the essence (Example 3) using the extract obtained from the black lily bulb and the essence (Example 4) obtained using the extract obtained from the Kissuge bulb with the two comparative examples. . In Example 3 and Example 4, it is obtained as an evaluation result by the expert panel sensory evaluation that the feeling of richness is greater than that of the two comparative examples, the moisture retention is high, the sustainability is large, and there is little stickiness.

  Table 3 shows a comparison between a cream using an extract obtained from a bulb of black lily (Example 5) and a cream using an extract obtained from a leaf of black lily (Example 6) and two comparative examples. is there. In Examples 5 and 6, the moisture persistence is stronger than that of the two comparative examples, and the smooth feeling is high as an evaluation result by the professional panel sensory evaluation. Moreover, Example 5 and Example 6 have less influence on the skin barrier function (TEWL: Transepidermal Water Loss / transdermal water transpiration) than the two comparative examples, and it can be seen that there is a moisturizing effect. Furthermore, as a result of conducting a one month use experiment with 35 women aged 35 to 57 as subjects, Example 5 and Example 6 were more remarkable in skin improvement effect and wrinkle improvement effect in the corners of the eyes than in the two comparative examples. there were.

  Table 4 shows an acne essence using an extract obtained from a black lily leaf (Example 7), an acne essence using an extract obtained from a Kisuge bulb (Example 8), and a Kygge leaf. The acne essence fee (Example 9) using the extract was compared with the two comparative examples. Example 7, Example 8, and Example 9 have a refreshing feeling, a convergence feeling, and skin flexibility as compared with the two comparative examples, and are obtained as evaluation results by the professional panel sensory evaluation. Furthermore, 18 women in the first group in their 20s with oily skin, 20 women in the second group, and 18 women in the third group were subjects, and the first group was expressed as in Example 7. 4 comparative examples 1 were used half a face for 1 month, the second group was used in Example 8 and Comparative Example 1 in Table 4 for 1 month each, and the third group was used in Examples 9 and 4 As a result of conducting an experiment in which Comparative Example 1 was used half a face for one month, Example 7, Example 8, and Example 9 were more effective in improving skin condition and acne than Comparative Example 1.

  Table 5 contrasted the whitening agent (Example 10) using an extract obtained from a black lily bulb and the whitening agent (Example 11) using an extract obtained from a leaf of katsuri to three comparative examples. Is. Example 10 and Example 11 have higher moisturizing properties than the three comparative examples, and are obtained as evaluation results by sensory panel sensory evaluation. Furthermore, when it sees about the culture melanocyte growth inhibitory action, when the maximum inhibition rate of the comparative example 3 of Table 5 was set to 100, Example 10 and Example 11 obtained the value of 79.7-80.5, It can be seen that there is an improvement effect of about 20%. Moreover, in the skin lightening test after sunburn, Example 10 and Example 11 were more remarkable in the whitening action than three comparative examples.

  As described above, according to the method and cosmetics for extracting the extract of the present invention, it is possible to provide an unprecedented superior cosmetic, which is useful in industries such as beauty, health care, and medical care. is there.
