SOLUTION: This elastase inhibitor is obtained by including an eluted fraction with 30 vol% ethanol aqueous solution when fractioning the following extract by an adsorption gel chromatography using a styrene-based polymer in a ethanol-water mixed solvent as an effective ingredient: at least one kind of extracts extracted from the group consisting of Sanguisorba officinalis L., Polygonum cuspidatum Sieb. et Zucc., Polygonum cuspidatum Sisb. et Zucc. var. hachidyoense Ohwi, Polygonum sachalinense Fr. Schm., Melissa officinalis L., Rosmarinus officinalis L., Carthamus tinctorius L. and Zingiber officinale Roscoe, or the extract of Sanguisorba officinalis L. with 50 vol% ethanol aqueous solution. This senility-preventing skin lotion is prepared by including at least one kind of above elastase inhibitors in an external preparation basis.

2. Description of the Related Art Elastin is a constituent protein found in highly extensible tissues such as arteries, tendons and skin, and is degraded and solubilized by elastase. Elastase is classified as a serine protease and is known to be derived from pancreas, leukocyte, fibroblast and the like. Excessive degradation of elastin due to the overexpression or activation of elastase may cause ischemic diseases such as emphysema, pulmonary fibrosis, bronchitis, bronchiectasis, pneumonia, rheumatoid arthritis, myocardial infarction, arteriosclerosis, pancreatitis, nephritis, teeth It is thought to cause periodontitis and skin diseases. Therefore, various elastase inhibitors have been searched for in order to suppress the excessively enhanced elastase activity.

The absorbance in the case of addition of sample (A s), calculated similarly measured absorbance for the control without addition of the sample divided by the (A c) (A s / A c), (1-A s / A c ) x 10
0 was calculated. The results are shown in Table 1.

As is clear from Table 1, Examples 1 to 6 of the present invention each showed a significant elastase inhibition rate of 20% or more at a low concentration of 100 μg / ml.
In particular, Example 1 showed a high inhibition rate of 68.7%. In Example 7, a very high inhibition rate of 74.0% was observed at a concentration of 50 μg / ml.
Elastase derived from human fibroblasts used in the evaluation of elastase inhibition rate was activated by interleukin-1α, a cytokine released by exposure to ultraviolet light, and has an inhibitory effect on this enzyme activity. It is suggested that Examples 1 to 7 of the present invention are effective in preventing and improving photoaging of skin due to ultraviolet rays.

The evaluation was performed by observing skin wrinkles and changes in skin elasticity before and after use. The wrinkles of the skin were evaluated by visual evaluation after photographing and the replica method, and the skin elasticity was evaluated by measurement with a cute meter. The results were evaluated for wrinkles and skin elasticity of skin after use for each panel in five stages: "improved", "slightly improved", "no change", "slightly worse", and "worse".

As described in detail above, the present invention exhibits high specificity and an inhibitory effect on elastase derived from human fibroblasts, and is caused by an excessive increase in elastase activity caused by exposure to ultraviolet rays. An elastase inhibitor capable of effectively preventing the decrease in the elasticity of the dermis matrix was obtained.
