Description

Cosmetic composition containing fermented sprout oat extract and method for producing the same

[0001] The present invention relates to a cosmetic composition comprising a fermented extract of oat sprouts and a method for producing the same, and more particularly, to a cosmetic composition comprising a fermented extract of oat sprouts obtained by fermenting an oat sprout extract extracted from oat sprouts and having various effects on the skin, and a method for producing the same.

[0002] Oat leaves have long been used as medicine and are known to be rich in nutrients, including vitamins, enzymes, and chlorophyll. Recently, the excellent nutrients and health functional substances contained in oats have become known for their effectiveness in balancing diets and improving physical constitution. This has led to increased interest in oats as a functional raw material for health and well-being. They are also receiving excellent evaluations as livestock feed.

[0003] Sprouted oats are young plants that have sprouted and grown to about 15 cm. Generally, oats are soaked in water for about a day, drained, and sown in a plastic basket or Styrofoam of an appropriate size lined with newspaper, covered with paper until they sprout, and then removed once they sprout and kept moist for about 7-10 days until they are 15 cm tall. It is known that oat sprouts contain a significantly higher content of dietary fiber, carotene, and vitamin C than other vegetables and fruits. In addition, in terms of pharmacological activity, oat sprouts are known to have the effects of lowering cholesterol, preventing constipation, preventing arteriosclerosis, having antioxidant activity, preventing aging, preventing osteoporosis, improving insomnia, and preventing anemia.

[0004] Various studies are being conducted on cosmetic compositions utilizing sprouted oats. Republic of Korea Patent Publication No. 10-2023-0127504 (published on September 1, 2023) discloses, "Sprouted oat postbiotic composition with skin whitening and wrinkle-improving activity and use thereof." This composition contains a fermented sprouted oat (Avena sativa) product, which is designed to have whitening and wrinkle-improving effects. However, the combination of sprouted oats and the Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus casei and Lactobacillus gasseri strains of the conventional patented technology did not show any remarkable effect, and accordingly, research is actively being conducted on a composition with improved skin and health effects by grafting other strains onto sprouted oats and fermenting them.

[0125] The 6-well plate on which the cells were cultured was washed once with 5 ml of cold phosphate-buffered saline (1x PBS) and the supernatant was removed. 200 μl (can be changed depending on the situation) of a solution prepared in the ratio of 1x RIPA buffer (100): Protease inhibitor (1): 100 mM PMSF (1) was dispensed and incubated at 4°C for 10 minutes. The cells were scraped with a scraper and collected in a 1.5 ml tube, and the vortex stirring and sonication were repeated three times for 30 seconds each. The cells were centrifuged at 16,000 g at 4°C for 20 minutes and the supernatant was transferred to a new 1.5 ml tube. Proteins were quantified using BCA assay.

[0126] 3) Western blot

[0127] An SDS-PAGE gel was prepared and 20 μl of protein samples were loaded. Electrophoresis was performed at 70 V for 20 minutes and 100 V for 70 minutes. Transfer was performed to a nitrocellulose membrane. After blocking in 5% skim milk, the primary antibody was added and incubated overnight at 4°C. After washing three times with 1X TBST, the secondary antibody was added and incubated at room temperature for 1 hour. After washing three times with 1X TBST, the bands were confirmed by reacting with ECL solution.

[0128] 4) Experimental results

[0129] The experimental results are as shown in Figures 7 to 9 and Tables 7 and 8.

[0130] Claudin-1 Increase Rate (%) Biomarker Concentration (%) Example 1 Comparative Example 1 Claudin-10 100.0 100.0 1010 5.4 100.1 50 112.7 101.3 100 123.5 105.9 2 50 125.9 108.6 500 131.8 111.4

[0131] Desmoglein 2 Increase Rate (%) Biomarker Concentration (%) Example 1 Comparative Example 1 Desmoglein 2 0 100.0 100.0 10103.6 101.4 50 107.2 102.4 100 111.5 103.2 250 116.8 107.4 500 122.9 110.6

[0132] As a result, it was confirmed that the expression level of Claudin-1 increased by 31.8% and the expression level of Desmoglein 2 increased by 22.9% in the group treated with 500 ppm of fermented sprout oat extract compared to the untreated group. It was confirmed that the expression levels of Claudin-1 and Desmoglein 2, which are involved in cell cohesion, increased further in Example 1, which underwent fermentation, compared to Comparative Example 1, which was not fermented. Accordingly, it was confirmed that the fermented sprout oat extract was effective in cell cohesion, and this means that as cell cohesion increases, the pore reduction effect increases.

[0133] Experimental Example 8. Sebum Control and Fat Differentiation Inhibition Activity

[0134] 1) Cell culture and sample processing

[0135] 3T3-L1 cells were seeded at 2x10 in a 6-well plate. 5 The cells were cultured at a concentration of 10 cells / well in a 37℃, 5% CO2 incubator for 48 hours. After treatment with adipogenic differentiation inducers such as 1 μM Dexamethasone, 0.5 mM IBMX, and 10 μg / ml Insulin, the cells were cultured for 48 hours. After treatment with 10 μg / ml Insulin, the medium was changed three times at 2-day intervals to induce adipogenic differentiation. After induction of adipogenic differentiation, the cells were stained with Oil Red O dye reagent and the absorbance was measured at a wavelength of 520 nm.

[0136] 2) Experimental results

[0137] The experimental results are shown in Fig. 10 and Table 9.

[0139] It was confirmed that when the sprout oat extract fermentation was treated, intracellular fat accumulation was reduced compared to the group treated with only a fat-inducing substance (MDI). In contrast, Comparative Example 1, which is an oat sprout extract, showed a significantly lower value. Meanwhile, as shown in Fig. 10, the part dyed red is fat, and it was confirmed that when the sprout oat extract fermentation was treated, intracellular fat accumulation was reduced compared to the group treated with only a fat-inducing substance (MDI).

[0151] As a result, it was confirmed that the expression levels of sebum-regulating factors PPAR γ and C / EBP α decreased in the group treated with the fermented sprout oat extract compared to the MDI alone treatment group. The PPAR γ factor decreased in a concentration-dependent manner with the fermented sprout oat extract, and in particular, the expression level was confirmed to decrease by 59.8% at a concentration of 1,000 ppm. The C / EBP α factor decreased in a concentration-dependent manner with the fermented sprout oat extract, and in particular, the expression level was confirmed to decrease by 53.4% ​​at a concentration of 1,000 ppm.
