[0050] (2) Use PBS as a solvent to prepare each sample to be tested according to the concentration in Table 1, so that the final concentration of the sample to be tested after being added to the reaction system is the concentration in Table 1.

[0051] (3) Prepare each group of reaction solutions in a centrifuge tube according to the reaction system shown in Table 2. After mixing well, incubate at 55°C for 4 days.

[0052] Table 2 Anti-sugarization test reaction system

[0053] Reaction components (mL) A B C D 2x Glycosylation reaction 1 0 1 0 2x Sample / control solution 1 1 0 0 PBS 0 1 1 2

[0054] (4) After the reaction is completed, cool the incubated solution to room temperature, centrifuge at 2000 r / min for 5 min, filter the supernatant through a 0.22 μm filter, and then take 200 μL of the reaction solution and add it to a 96-well plate. Use a fluorescence enzyme marker to detect the fluorescence intensity of each group under the conditions of an excitation wavelength of 320 nm and an emission wavelength of 460 nm.

[0055] (5) AGES inhibition rate = [1-(A-B) / (C-D)]x100%.

[0056] Tyrosinase inhibition test:

[0057] (1) Use PBS to prepare a tyrosinase solution with a final concentration of 2KU and an L-tyrosine solution with a final concentration of 0.2957 mg / mL.

[0058] (2) Use PBS as a solvent to prepare each sample to be tested according to the concentration in Table 1, so that the final concentration of the sample to be tested after being added to the reaction system is the concentration in Table 1.

[0059] (3) Set T (sample group), T0 (sample control group), C (solvent group), and C0 (solvent control group). The reaction systems of each group are shown in Table 3.

[0060] Table 3 Tyrosinase inhibition test reaction system

[0061] Reaction components T T0 C C0 Tyrosinase solution (mL) 0.1 / 0.1 / PBS (mL) / 0.1+0.4 2.5 0.1+2.5+0.4 Sample to be tested (mL) 2.5 2.5 / / L-tyrosine solution (mL) 0.4 / 0.4 /

[0062] (4) According to the reaction system of each group, add the corresponding volume of tyrosinase solution, PBS, and sample to be tested to the centrifuge tube, and add 0.1 mL of PBS to the T0 and C0 groups. Mix the solution in the tube well and incubate at room temperature for 10 min.

[0063] (5) Add 0.4 mL L-tyrosine solution to the T and C groups of centrifugal tubes, and add 0.4 mL PBS to the T0 and C0 groups. Mix the solution in the tube thoroughly, and incubate at room temperature for 10 min.

[0064] (6) After the incubation is completed, transfer the solution in each group to a 96-well plate (n=3), and use a multifunctional enzyme marker to detect the absorbance value at a wavelength of 470 nm.

[0065] (7) The tyrosinase activity inhibition rate = [1-(T-T0) / (C-C0)]x100%.

[0066] B16 cell melanin inhibition test:

Place in an incubator for 60 h.

[0070] (4) Trypsinize and collect the cells in each group, centrifuge to remove the supernatant, collect the precipitate and dry it. Use the BCA method to quantitatively detect the total protein concentration in each cell precipitate, and calculate the total protein content of each group of precipitates.

[0071] (5) Calculate and add an appropriate amount of NaOH solution according to the total protein content of each group to make the protein concentration of each group of precipitates after dissolution equal.

[0072] (6) 70-degree metal bath for 10 min to dissolve and disperse the precipitate into a uniform solution, transfer to a 96-well plate (n=3), and use a multifunctional enzyme marker to detect the absorbance value at a wavelength of 405 nm.

[0073] (7) The melanin production rate of each group = (OD 实验组 -OD NaOH ) / (OD Control -OD NaOH ) x 100%.

[0074] (8) Melanin improvement rate = (melanin production rate of the model group - melanin production rate of the sample group) / (melanin production rate of the model group - melanin production rate of the blank group) x 100%.

[0075] Safety test: select qualified patch test material. Put the test substance (Example 6, Example 7) into the patch tester, and the amount is about 0.020 mL-0.025 mL (liquid is added on the filter paper attached to the patch tester and placed in the patch tester). The patch tester with the test substance is attached to the back or forearm of the subject with a non-irritating tape, and the palm is pressed lightly to make it evenly attached to the skin for 24 h. The judgment criteria are shown in Table 4 (closed patch test skin reaction evaluation criteria).

[0076] Table 4 Closed patch test skin reaction evaluation criteria

[0077] Degree of reaction Score grade Skin reaction - 0 Negative reaction ± 1 Suspected reaction: only weak erythema + 2 Weak positive reaction (erythema reaction): erythema, infiltration, edema, and possibly papules ++ 3 Strong positive reaction (vesicle reaction): erythema, infiltration, edema, papules, and vesicles; reaction can extend beyond the test area +++ 4 Very strong positive reaction (fusion vesicle reaction): clear erythema, severe infiltration, edema, and fusion vesicles; reaction extends beyond the test area

[0078] Result determination: when the number of people with grade 1 skin adverse reactions is more than 5, or the number of people with grade 2 skin adverse reactions is more than 2 (except that the number of people with grade 2 reactions in the deodorant product patch test is more than 5), or any one case of grade 3 or above skin adverse reactions occurs, it is determined that the test substance has skin adverse reactions on the human body;

[0079] The test results are shown in Tables 5 and 6;

[0082] The safety test results are shown in Table 6:

[0083] Table 6 Closed patch skin reaction test results

[0084]

[0085] Conclusion: the human patch test results show that:

[0086] Example 30 of the subject skin showed negative reactions (scored as grade 0), according to the HAT-SOP-F1-PZ-092 human patch test judgment criteria, Example 6 and Example 7 had no adverse reactions on human skin.

[0087] Result analysis:

[0088] As can be seen from Examples 1 to 3 and Comparative Examples 1 and 2 of the present application, both of them exhibit a slight AGES inhibition effect when used alone at a certain concentration, and when used in combination, such as Example 2, they exhibit a more obvious AGES removal effect, which shows that the acetylhydroxyproline and white water lily extract of the present application not only exist as anti-glycation components, but also exhibit a more significant synergy;

[0089] When the two anti-glycation ingredients are applied to the comprehensive formula, we find the same significant whitening synergistic effect and melanin improvement effect, specifically, referring to Examples 4 to 7 and Comparative Examples 3 to 5, in the dual anti + whitening system, the use of acetyl hydroxyproline alone cannot bring about improvement in whitening effect, and when the two are used in combination, the improvement in whitening effect is obvious; similarly, the same conclusion is reached in Examples 8 and 9 and Comparative Examples 6 and 7.

[0090] Based on the above result analysis, it can be seen that the dual anti-glycation composition of the present application has anti-glycation synergy, and when it is applied to the dual anti + whitening system, it further exhibits whitening synergy.
