1. DPPH free radical scavenging experiments
(1) Sample preparation: the samples provided in examples 1-3, comparative examples 1-9 were each dissolved in 30wt%1, 3-propanediol aqueous solution for use.
(2) DPPH free radical scavenging test method
Adding 2.0mL of DPPH test solution with the mass concentration of 45.8mg/L and 0.05mL of 5% sample solution into a test tube, supplementing the total volume to 3mL by 50% ethanol (v/v), shaking uniformly, carrying out light-proof reaction for 30min, and measuring absorbance at 517nm by using A1 cm cuvette, and marking as A1; adding 2mL of absolute ethyl alcohol and a sample to be detected with a corresponding volume into a test tube, supplementing the total volume to 3mL by using 50% ethanol (v/v), and recording the measured absorbance as A2; to the test tube, 2mL of DPPH test solution and 1mL of 50% ethanol (v/v) were added, and the absorbance was measured and designated as A3. Calculating the clearance rate (Y) of the liquid to be tested to DPPH free radicals according to the following formula;
the calculation formula of the DPPH free radical clearance is as follows: y (%) = [1- (A1-A2)/A3 ] ×100%;
wherein: a1 is the absorbance value of the system after the blank is cleared of DPPH, A2 is the absorbance value of the system after the sample is cleared of DPPH, and A3 is the absorbance value of the reaction system before the sample is not added.
(3) IC50 values of each sample were obtained based on DPPH radical scavenging rate, and the results are shown in Table 1.
TABLE 1
As shown in the test results of Table 1, the sea fennel extract, the lactobacillus fermentum and the phenethyl resorcinol all had a certain free radical scavenging effect. As is evident from comparison of examples 1-3 with comparative examples 1-9, the IC50 values of examples 1-3 were smaller than those of comparative examples 1-3 of single component and comparative examples 4-6 of any two component combinations in the case of the same total active ingredient addition amount, indicating that there was a stronger inhibition effect on DPPH when the sea fennel extract, lactobacillus fermentum and phenethyl resorcinol were compounded, and that the improvement of the inhibition effect was not dose-dependent with the active ingredient addition amount, confirming that there was a synergistic effect when the three functional ingredients were compounded. It is assumed that this is because the plant-derived sea fennel extract contains various flavonoid components, the lactobacillus fermentum component contains natural components such as tocopherol and glutathione, and the components can participate in the decomposition of peroxides, while the phenethyl resorcinol is an excellent free radical scavenger, has a strong inhibition effect on oxidation reactions such as chain growth, and the synergistic effect of various components can significantly improve the antioxidation effect.
In addition, comparing the results of example 1 with those of comparative examples 7 to 9, it can be seen that when any component in the composition of the present application is replaced with other similarly effective components, it is difficult to achieve the effect of the composition of the present application. It is presumed that the natural source of the sea fennel extract and the seaweed extract have different contents and types of polyphenols and flavonoids, which affect the scavenging efficiency of free radicals. While different species have a greater impact on the fermentation product, for example: the volatile components in 40 are obtained by fermenting chicory roots by using the North long spore yeast, and only 27 components are obtained by fermenting chicory roots by using the Bacillus pumilus. (Chang Jian, xu Shitao, huang Jing, etc.) analysis of volatile components of chicory root fermentation extracts of different species and application [ J ]. Chinese brewing, 2019, 38 (5): 199-203.) it was therefore presumed that in the composition system of the present application, the product obtained after fermentation with Lactobacillus contains more substances which are advantageous for the synergistic inhibition of free radicals with phenethyl resorcinol, sea fennel extract. As can be seen from comparative examples 1 and 9, the combination of phenethyl resorcinol and sea fennel extract and lactobacillus fermentum has stronger effect on DPPH than arbutin, and the synergistic effect of the three is stronger.
2. Tyrosinase inhibition assay
(1) Sample preparation: the samples provided in examples 1-3, comparative examples 1-9 were each dissolved in 30wt%1, 3-propanediol aqueous solution for use.
(2) Tyrosinase inhibition test method
The sample solution, phosphate Buffer Solution (PBS) with pH value of 6.8 and dopa solution with mass fraction of 0.1% are sucked, fully mixed, incubated at 30 ℃ for 5min, tyrosinase solution (activity 100U/mL) with corresponding volume is respectively added, incubated at 30 ℃ for 10min, quickly transferred into a cuvette, and absorbance is measured at 475 nm.
The relative inhibition of tyrosinase by the sample solution (I) was calculated as follows.
I=[(A1-A2)-(A3-A4)]/(A1-A2)×100%;
Wherein: a1, A2, A3 and A4 are the absorbance of the solutions of groups 1-4, respectively.
The formulations of the 4 groups of solutions are shown in Table 2.
TABLE 2
Group of Group 1 Group 2 Group 3 Group 4
Sample solution (mL) 0 0 1.0 1.0
Phosphate buffered solution (mL) 2.0 2.5 1.0 1.5
Dopa solution (mL) 1.0 1.0 1.0 1.0
Tyrosinase solution (mL) 0.5 0 0.5 0
Total volume (mL) 3.5 3.5 3.5 3.5
(3) The test results are shown in Table 3.
TABLE 3 Table 3
As can be seen from the test results of Table 3, comparative examples 1 to 3 each use a single sea fennel extract, lactobacillus fermentum and phenethyl resorcinol, and have a certain inhibition effect on tyrosinase, and as can be seen from examples 1 to 3, tyrosinase inhibition effect after combination of sea fennel extract, lactobacillus fermentum and phenethyl resorcinol is significantly higher than comparative examples 1 to 3 and comparative examples 4 to 6 of any two components. The three are compounded with the best effect, which is probably due to the fact that polyphenol groups in the phenethyl resorcinol can be bonded with the active center of tyrosinase, and the phenethyl resorcinol can form hydrogen bonds with the end groups of tyrosinase, so that the catalytic action of tyrosinase on a substrate is reduced. The sea fennel extract contains a certain amount of plant polyphenol, and can occupy relevant sites of enzyme after tyrosinase is combined through end groups, so that the combination of a substrate and the enzyme is inhibited. The lactobacillus ferment contains phytic acid, polyphenol and other components, and has stronger capturing effect on free radicals.
In addition, comparing example 1 with comparative examples 7 to 9, it is understood that the combination of the sea fennel extract, lactobacillus fermentum and phenethyl resorcinol has a stronger tyrosinase inhibitory effect, probably because arbutin is a competitive inhibition of tyrosinase activity, phenethyl resorcinol is a non-competitive inhibition, and the mechanism of action is somewhat different, so that the synergistic effect between the compositions is hindered for replacement of phenethyl resorcinol with arbutin. Furthermore, as mentioned above, the substitution of lactobacillus ferments with bacillus subtilis ferments may also have an effect on the synergistic effect of the composition, as well as the differences in the different plant components and in the different species fermentation components.
3. Inflammatory factor inhibition assay
(1) Sample preparation: the samples provided in examples 1-3, comparative examples 1-9 were each dissolved in 30wt%1, 3-propanediol aqueous solution for use.
(2) Method for testing NO and TNF-alpha inhibition in cells
RAW264.7 cells at 1X 10 4 Cell/well density was added to 96-well plates and placed at 37℃in 5% CO 2 After 24h incubation in incubator, old medium was discarded and washed 2 times with PBS. After 1h of treatment of the cells with the sample solution, complete medium containing 100ng/mL of LPS was added for further incubation for 24h, and corresponding blank (i.e.no LPS and test substance were added) and model (only LPS was added) groups were set, the supernatant was collected, and after centrifugation at 1000rpm for 10min 400. Mu.L of supernatant was taken, and the NO and TNF-. Alpha.content was determined according to the NO detection kit instructions and ELISA kit instructions, respectively. Each set of experiments was independently repeated 3 times.
(3) The results of the inhibition of NO are shown in Table 4, FIG. 1 (average value in Table 4); the results of the inhibition of TNF-. Alpha.are shown in Table 5 and FIG. 2 (average value in Table 5). The average value is that of the inhibition results of 3 groups, namely 3 groups tested in parallel. From the average value, the standard deviation is calculated according to the following formula. The standard deviation can reflect the discrete degree of each data, if the standard deviation is too large, the data is inaccurate, the average value is obtained through a plurality of groups of experiments, and the standard deviation is calculated so as to show whether each group of data has a larger difference from the average value.
Standard deviation:
TABLE 4 Table 4
Average value of Standard deviation of
Example 1 6.051 0.550
Example 2 6.418 0.379
Example 3 6.179 0.335
Comparative example 1 8.902 0.120
Comparative example 2 8.056 0.193
Comparative example 3 8.583 0.198
Comparative example 4 7.916 0.215
Comparative example 5 8.504 0.243
Comparative example 6 7.752 0.245
Comparative example 7 7.669 0.234
Comparative example 8 7.255 0.255
Comparative example 9 7.017 0.094
Blank group 1.413 0.113
Model group 9.356 0.267
TABLE 5
From the results of tables 4 to 5, the standard deviation of each sample was within a reasonable range. As can be seen from the results of FIGS. 1-2, the sea fennel extract, the lactobacillus fermentum and the phenethyl resorcinol all have a certain inhibitory effect on inflammatory factors. As is evident from comparison of examples 1 to 3 with comparative examples 1 to 9, the compositions of examples 1 to 3 have significantly higher inhibitory effects on inflammatory factors than those of comparative examples 1 to 3 of a single component and comparative examples 4 to 6 of any two component combinations. The results show that the combination effect of the fennel extract, the lactobacillus fermentum and the phenethyl resorcinol is optimal, which is probably due to the fact that the prebiotic components contained in the lactobacillus fermentum in the composition can inhibit inflammatory factors, the fennel extract has a certain inhibiting effect on inflammatory factors, and the polyphenol structure of the phenethyl resorcinol can generate a synergistic effect with small molecular components so as to inhibit the generation of inflammatory factors.
Further, it is understood from comparison of example 1 with comparative examples 7 to 9 that the combination of the sea fennel extract, lactobacillus fermentum and phenethyl resorcinol has a stronger inflammatory factor inhibitory effect, presumably because the different plant components and different species fermentation components, and the different structure and functional group of arbutin and phenethyl resorcinol have an influence on the synergistic effect of the composition.
