Description

Technical Field

[0001] The invention relates to the technical field of plant extracts, and in particular to a composition of a fermentation product and a nephrite extract and application thereof in preparing skin care products. Background Art

[0002] Anti-aging and whitening have always been the two key goals that consumers are constantly pursuing, and they are the main line of skin care demands for people of all ages and skin types. Skin aging is not only manifested in changes in appearance such as wrinkles, sagging, and sagging, but is also related to slowed skin metabolism, water loss, and weakened barrier function; while skin pigmentation greatly affects the uniformity of facial color and overall appearance.

[0003] At present, there are many kinds of products with whitening effect on the market, but some of them cannot have both whitening and anti-aging effects, and the effect is single, or the whitening and anti-aging effects are not ideal. Therefore, it is of great value and significance to develop a product with significant whitening and anti-aging effects and few side effects.

[0004] The ground nasturtium is a large perennial clumping herb of the Musaceae family. It has a long history of being used as a herbal medicine. Its pharmacological effects include hemostasis, anti-inflammatory, antibacterial, and anti-tumor.

[0005] At present, there is no research or report on using the combination of the Herba Lysimachiae extract and probiotics for whitening and anti-aging. Summary of the invention

[0006] In view of this, the present invention provides a Herba Lysimachiae extract and application thereof in preparing antioxidant, anti-aging and whitening products.

[0007] The composition provided by the invention comprises a nephrolepis radix extract and a fermentation filtrate of Bifidobacterium longum.

[0008] The present invention compounded the extract of Herba Lycopodii and the fermentation filtrate of Bifidobacterium longum infantis subsp. Studies have shown that the whitening and anti-aging effects of the composite obtained by compounding the two are significant. Under a specific ratio, the two components have an obvious synergistic effect. In addition, the present invention also attempts to compound other strains (such as bifid yeast) with the Herba Lycopodii extract, and it is found that the effect is obviously not as good as the composition of the present invention.

[0009] In the composition of the present invention, the mass ratio of the Bifidobacterium longum fermentation broth and the Herba Lycopodii extract is (1~100):(100:1), specifically 100:1, 10:1, 1:1, 1:10 or 1:100, and also includes any other mass ratio and mass ratio range within the above range.

[0010] In the composition of the present invention, the Bifidobacterium longum includes Bifidobacterium longum subsp. infantis. Preferably, the Bifidobacterium longum subsp. infantis; in some specific embodiments, the deposit number of the Bifidobacterium longum subsp. infantis is CGMCC NO.27851.

[0011] In a specific embodiment of the present invention, the Bifidobacterium longum fermentation broth is Bifidobacterium longum subspecies infantis fermentation broth, and the preparation method refers to Chinese patent application number 202410036419.6, comprising the following steps:

[0012] (1) Preparation of glycerol tube strains

[0013] 1) Activation of the original lyophilized powder: transfer the lyophilized powder to 100 mL of Huankai MRS triangular flask culture medium, and culture at 37℃ for 20-24 hours to prepare bacterial solution for use;

[0014] 2) Isolate single colonies: Streak the bacterial liquid on MRS solid culture medium plates, culture at 37℃ for 48 hours, and keep them for later use after they grow up;

[0015] 3) Activation of single colony: transfer single colony to 100 mL liquid Erlenmeyer flask culture medium, and activate the bacterium-making liquid by anaerobic static culture at 37℃ for 20 hours. Check under a microscope to see if OD*10>0.260 and pH<4.50 meet the standards;

[0016] 4) Preservation of original glycerol tube strains: 5% inoculation of the above bacteria (OD*10>0.260 after 20-24 hours of culture can be considered qualified) is transferred to the culture medium in the triangular flask of formula card 1, and OD*10>0.260 and pH<4.50 are detected after 20 hours of culture. After the microscopic examination meets the standards, the strains are preserved in glycerol tubes (0.70 mL of preservative solution and 0.70 mL of bacterial solution).

[0017] 5) Establishment of seed batches: The seed batch system for production strains should be established in accordance with the relevant provisions of "Management and Quality Control of Strains for Production and Inspection of Biological Products".

[0018] (2) The strain Bifidobacterium longum subsp. infantis obtained in step (1) was inoculated into the culture medium with an inoculum amount of 5% (the culture was qualified if OD*10>0.260 was detected after 20-24 hours of culture), and cultured at 37°C for 20-24 hours. The supernatant was obtained by centrifugation and freeze-dried to obtain a concentrated fermentation liquid;

[0019] The culture medium involved in the previous preparation method includes: 12 g / L lactose, 10 g / L wheat peptone, 10 g / L yeast powder, 2 g / L sodium acetate, 2 g / L dipotassium hydrogen phosphate, 2 g / L triammonium citrate, 0.58 g / L magnesium sulfate 7hydrate, 0.05 g / L manganese sulfate and 2 g / L Tween 80.

[0020] In the composition of the present invention, the extract of the ground nasturtium is the extract of the ground nasturtium and its flower buds.

[0021] In the composition of the present invention, the preparation method of the extract of the nephrolepis terrestris comprises: taking the flowers and buds of the nephrolepis terrestris, cold-immersing and extracting them with 75% ethanol, and concentrating them to dryness under reduced pressure to obtain a crude extract of the nephrolepis terrestris.

[0022] The present invention also provides the use of the composition in preparing products with whitening and anti-aging effects.

[0023] In the present invention, free radical oxidation and UVA damage are both important causes of aging. In the present invention, the composition achieves anti-aging effects by resisting oxidation, UVA damage and regulating the levels of genes and proteins related to anti-aging.

[0024] In some embodiments, the present invention has been found through research that the composition of the present invention can effectively scavenge DPPH free radicals and exert anti-aging effects through antioxidant effects.

[0025] In some embodiments, the present invention has found through research that the composition of the present invention can effectively improve the cell viability after UVA stimulation and has a significant resistance to UVA damage. Specifically, the cells are fibroblasts.

[0026] MMP1 is a matrix metalloproteinase, and its main function is to decompose interstitial collagen, including types I, II and III. Collagen is the main structural protein in the dermis of the skin. When collagen is degraded, the mechanical support of the skin is lost, which leads to the appearance of wrinkles. MMP3 is a matrix metalloproteinase III, which can degrade some protein components in the extracellular matrix, such as collagen. In the skin, the degradation of collagen is related to skin aging. Some studies have shown that MMP1 and MMP3 help improve the elasticity and firmness of the skin. Therefore, inhibiting MMP1 and MMP3 can achieve a certain effect in resisting the formation of wrinkles and exert anti-aging effects.

[0027] COL1 is type I collagen, which accounts for about 80% of the dermis. Type I collagen helps the dermis (middle layer of the skin) form fibroblasts, helps new cells grow, provides structure, strength and support for the skin, and makes the skin plump and full. Promoting the expression of the COL1 gene can achieve a certain effect of resisting the formation of wrinkles, thereby achieving an anti-aging effect.

[0028] In some embodiments, the present invention has been found through research that the composition of the present invention can inhibit the transcription of MMP1 and MMP3 genes, inhibit the expression of MMP1 protein, and promote the transcription of COL1 and COL3 genes.

[0029] The present invention also provides a product with whitening and anti-aging effects, comprising the above-mentioned composition.

[0030] In the product of the present invention, the concentration of the fermentation filtrate of Bifidobacterium longum is 0.002mg / ml~10mg / ml, preferably 0.002mg / ml~0.02mg / ml, 0.002mg / ml~0.1mg / ml, 0.002mg / ml~0.2mg / ml, 0.02mg / ml~0.1mg / ml, 0.02mg / ml~0.2mg / ml, 0.1mg / ml~1mg / ml, 0.1mg / ml~5mg / ml, 0.1mg / ml~10mg / ml, 1mg / ml~5mg / ml, 1mg / ml~10mg / ml or 5mg / ml~10mg / ml; specifically 0.002mg / ml, 0.02mg / ml, 0.1mg / ml, 0.2mg / ml, 1mg / ml, 5mg / ml or 10mg / ml.

[0031] In the product of the present invention, the concentration of the Herba Lycoris Radiatae Extract is 0.002mg / ml~10mg / ml, preferably 0.002mg / ml~0.02mg / ml, 0.002mg / ml~0.1mg / ml, 0.002mg / ml~0.2mg / ml, 0.02mg / ml~0.1mg / ml, 0.02mg / ml~0.2mg / ml, 0.1mg / ml~1mg / ml, 0.1mg / ml~5mg / ml, 0.1mg / ml~10mg / ml, 1mg / ml~5mg / ml, 1mg / ml~10mg / ml or 5mg / ml~10mg / ml; specifically 0.002mg / ml, 0.02mg / ml, 0.1mg / ml, 0.2mg / ml, 1mg / ml, 5mg / ml or 10mg / ml.

[0032] In the present invention, the dosage forms of the products include skin care products and health care products; the dosage forms of the skin care products include but are not limited to creams, emulsions, solutions, sprays, gels or powders; the dosage forms of the health care products include tablets, emulsions, granules, pills, liquid preparations, ointments or patches.

[0033] The invention provides a composition of a fermentation filtrate of Bifidobacterium longum subsp. Infantis and a Herba Lycopodii extract; experiments show that the composition formed by the two can effectively remove DPPH free radicals, resist cell damage caused by UVA, downregulate the expression of aging-related genes and proteins, upregulate the expression of anti-aging genes, and inhibit the activity of tyrosinase, and has good whitening and anti-aging effects. After the two are compounded in a specific ratio, an obvious synergistic effect can be produced, and the composition has a good application prospect in skin care products.

[0061] It should be understood that in various embodiments of the present invention, serial numbers do not mean the order of execution, some or all of the steps can be executed in parallel or sequentially, and the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0062] The numerical ranges and parameters involved in the present invention have been presented in the specific embodiments as accurately as possible. However, any numerical value inherently inevitably contains standard deviations due to individual testing methods. Therefore, unless otherwise explicitly stated, it should be understood that all numerical ranges or specific data used in this disclosure may have certain reasonable deviations within a certain range.

[0063] Some cases are recorded in the embodiments and comparative examples of the present invention. The embodiments show some implementations of the present invention.

[0080] Example 1

[0081] 1. DPPH free radical scavenging rate test to determine the antioxidant effect

[0082] 1.1 Determination of DPPH free radical scavenging rate of samples

[0083] (1) Preparation of stock solution: 95% ethanol: Take 95 ml of ethanol in a measuring cylinder and add ultrapure water to 100 ml. 0.03% DPPH stock solution: Weigh 15 mg of DPPH powder into a 50 ml brown volumetric flask, add about 40 ml of 95% ethanol, sonicate to completely dissolve it, dilute to the mark, shake well, and use as DPPH stock solution:

[0084] (2) Preparation of 0.03‰ DPPH working solution: Based on the required amount of DPPH solution, measure 1 / 10 volume of 0.03% DPPH stock solution and dilute it to prepare 0.03‰ DPPH working solution.

[0085] (3) The positive control substance Trolex was diluted to 0.025 mM with pure water to verify the test system.

[0086] (4) The test substance is diluted with pure water to form samples of multiple concentrations. Referring to Table 1, set up sample tubes (T), sample background (T0), DPPH tubes (C) and solvent background (C0) in a 96-well plate. Three parallel wells should be set up for each sample well (T) of each test concentration of each sample, and three parallel wells should also be set up for the DPPH tube (C).

[0087] (5) Add 50 μl of sample solution of the same concentration and 100 μl of pure water to the sample tube (T) and sample background (T0), and add 150 μl of pure water to the DPPH tube (C) and solvent background (C0).

[0088] (6) Add 50 μl of DPPH ethanol solution to each of the sample tube (T) and DPPH tube (C). Replace the sample background (T0) and solvent background (C0) with 50 μl of 95% ethanol.

[0089] (7) Let the reaction stand at room temperature for 5 minutes and measure OD 517 .

[0090] (8) Calculate the DPPH free radical scavenging rate: scavenging rate (%) = (1- )×100%.

[0091] (9) In the formula, T is the absorbance of the sample well, that is, the absorbance of the solution after the sample reacts with DPPH; T0 is the background absorbance of the sample; C is the average of the three absorbances of the DPPH well, that is, the absorbance of the DPPH solution when no sample is added; and C0 is the background absorbance of the solvent.

[0092] (10) Statistical analysis and graphing: GraphPad Prism 9 software was used for statistical analysis and graphing. If the data met the normal distribution and homogeneity of variance, paired t-test was used for pre- and post-experimental comparison within the group, and one-way analysis of variance was used for comparison of means between groups. P < 0.05 indicated statistically significant differences.

[0106]

[0107] Conclusion: Different ratios of filtrate and crude extract of Hedysarum sutchuenensis showed excellent DPPH free radical scavenging rate. When the ratio of filtrate: crude extract of Hedysarum sutchuenensis was 100:1, the DPPH free radical scavenging rate increased significantly compared with the single filtrate and crude extract of Hedysarum sutchuenensis. BLISS >0, indicating that the filtrate and the crude extract of Nasturtium schrenkiana have strong antioxidant capacity at the combination of 100:1, and the filtrate and the crude extract of Nasturtium schrenkiana have a synergistic anti-aging effect.

[0108] 2. MTT assay to determine cell viability

[0109] 2.1 Determination of cell viability

[0110] (1) HFF fibroblasts were plated into 96-well plates.

[0111] (2) On the second day, the culture medium was replaced with PBS solution and the cells were subjected to 30 J / cm 2 After UVA irradiation, fresh pre-warmed culture medium was replaced and the test samples were then added to stimulate the cells for 24 h. The final culture medium volume in each well was 200 μl.

[0112] (3) Discard the culture medium and add MTT solution (0.5 mg / mL) to each well at 37°C and incubate for 4 hours. Discard the culture medium and add 150 µl DMSO to dissolve the precipitate. Measure the absorbance at OD 490 nm using a multifunctional microplate reader and calculate the cell viability percentage using the following formula: Cell viability (%) = 100% ×

[0113] The results are shown in Tables 5~7 and Figures 4 to 6 .

[0115] Table 5 Numerical table of cell viability of filtrates of different concentrations

[0116]

[0117] Summary: After UVA treatment, the cell viability decreased significantly, indicating that UVA stimulation caused damage to the cell survival rate. On this basis, after treatment with different concentrations of filtrate, the detected cell viability increased significantly compared with UVA treatment alone, indicating that the filtrate has the effect of resisting cell damage caused by UVA and has anti-aging effects.

[0118] 2.3 Effect of extract of Herba Lycoris Radiatae against UVA damage (MTT)

[0119] Table 6 Numerical table of cell viability of crude extracts of different concentrations of Hedysarum sphaerocephalum

[0120]

[0121] Summary: After UVA treatment, the cell viability decreased significantly, indicating that UVA stimulation caused damage to the cell survival rate. On this basis, after treatment with different concentrations of crude extract of Geum schrenkiana, the detected cell viability increased to a certain extent compared with UVA treatment alone, indicating that the crude extract of Geum schrenkiana has the effect of resisting cell damage caused by UVA and has anti-aging effects.

[0122] 2.4 Synergistic effect of different ratios of filtrate + crude extract of Herba Lycoris Radiatae against UVA damage (MTT)

[0123] Table 7 Cell viability values ​​of different ratios of filtrate and crude extract of Hedysarum sphaerocephalum

[0124]

[0125] Summary: After UVA treatment, the cell viability decreased significantly, indicating that UVA stimulation caused damage to the cell survival rate, and the anti-aging model was successfully established; under UVA stimulation, the filtrate, the crude extract of the scutellaria baicalensis and the combination were used to treat and count the cell survival rate. The results showed that when the ratio of the filtrate: the crude extract of the scutellaria baicalensis was 100:1, the cell survival rate increased significantly compared with the single filtrate and the crude extract of the scutellaria baicalensis.

[0126] 3 Detection and analysis of anti-aging genes (qPCR)

[0127] 3.1 qPCR determination of anti-aging gene expression

[0128] (1) HFF fibroblasts grown in 12-well plates were stimulated with UVA to establish the model.

[0129] (2) After modeling, the drugs were administered according to the dosing schedule in Table 8, and the cells were collected 24 hours later.

[0130] (3) Use an RNA total extraction kit to extract cellular RNA, and use a reverse transcription kit to reverse transcribe and synthesize cDNA.

[0131] (4) Amplification was performed using SYBR Green qPCR Master Mix fluorescent quantitative PCR instrument, and the specificity of the primers was checked by melting curve.

[0141] MMP1 is a matrix metalloproteinase, which mainly decomposes interstitial collagen, including types I, II and III. Collagen is the main structural protein in the dermis of the skin. When collagen is degraded, the mechanical support of the skin is lost, which leads to the appearance of wrinkles. After the test object acts on the cell model, the anti-wrinkle effect of the test object is evaluated by detecting the changes in MMP1 gene expression.
