Description

Cosmetic composition for preventing skin aging The present invention relates to a cosmetic composition for preventing skin aging, and more specifically, to a cosmetic composition for preventing skin aging comprising sprouted red bean extract as an active ingredient. With the advancement of modern medicine and the environment, as well as improvements in living standards, average life expectancy is increasing. Consequently, the silver industry targeting the elderly is emerging, and notably, there is a growing demand for measures to prevent skin changes associated with aging. Skin aging can be classified into photoaging caused by external factors such as sunlight and natural aging, which is a physiological aging phenomenon. Skin aging that primarily occurs in facial areas such as the face results in irregular skin changes, such as deepening fine wrinkles and roughening of the skin surface, due to the aforementioned skin aging factors. To meet these demands, many cosmetics are being sold emphasizing anti-aging functions, but there are issues such as the need for long-term use or the use of expensive raw materials. Therefore, there is a growing need for new cosmetic compositions for preventing skin aging. Hereinafter, embodiments of the present invention are described in detail so that a person skilled in the art can easily implement them. Since the present invention is susceptible to various modifications and may have various embodiments, specific embodiments are described in detail by way of example. However, this is not intended to limit the present invention to specific embodiments, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the present invention. Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application. <Preparation Example 1> 200 g of red beans were soaked in purified water at 20 ℃ for 6 hours, then removed and germinated for 5 days under conditions of 25 ℃ and 40% humidity. <Example 1> The germinated red beans from Preparation Example 1 were collected, air-dried, and ground using a grinder. 15 g of the beans were reflux-extracted twice with 250 ml of 60% (v/v) ethanol for 4 hours in a constant temperature water bath at 75 ℃. The extract was naturally filtered through filter paper, and the filtrate was concentrated under reduced pressure at 50 to 60 ℃ to obtain the extract. <Example 2> The extract was obtained in the same manner as in Example 1, except that 70% (v/v) concentration ethanol was used. <Comparative Example 1> An extract was obtained in the same manner as in Example 1, except that 30% (v/v) concentration ethanol was used. <Comparative Example 2> An extract was obtained in the same manner as in Example 1, except that 50% (v/v) concentration ethanol was used. <Comparative Example 3> An extract was obtained in the same manner as in Example 1, except that 80% (v/v) concentration ethanol was used. <Comparative Example 4> An extract was obtained in the same manner as in Example 1, except that 95% (v/v) concentration ethanol was used. <Experimental Example 1> The extract yields and yields of Examples 1 to 2 and Comparative Examples 1 to 4 are shown in Table 1 below. Referring to Table 1, the yield of Examples 1 and 2 is higher than that of Comparative Examples 1 to 4, and in terms of yield, Examples 1 and 2 show a yield of 15% or more, while Comparative Examples 1 to 4 show a yield of less than 14%.

The mixture was then reacted in a dark room for 30 minutes, and the absorbance was measured at 517 nm using a microplate reader (Epoch Biotek, USA). At this time, the DPPH free radical scavenging activity (%) was calculated as "[1 - (absorbance of sample-added group / absorbance of sample-free group)] * 100", and the results are shown in Table 2. Referring to Table 2, it can be seen that the antioxidant effects of Example 1 and Example 2 are relatively superior for each concentration. density (µg/ml)Comparative Example 1Comparative Example 2Example 1Example 2Comparative Example 3Compa
