Test example three whitening efficacy evaluation tests (tyrosinase activity inhibition test)

Tyrosinase is the rate-limiting enzyme in the melanin synthesis pathway, and mainly influences the generation of melanin by influencing the conversion of tyrosine into dopa and the oxidation of dopa into dopaquinone, and inhibits the generation of melanin by inhibiting the activity of tyrosinase. Therefore, the efficacy of the inhibition of tyrosinase was evaluated by determining the results of the inhibition of tyrosinase in example seven.

Solution preparation:

Test example four antioxidant evaluation test (DPPH radical scavenging test)

DPPH radical is a synthetic, one-electron, stable, nitrogen-centered paramagnetic compound. In the presence of the radical scavenger, DPPH radical accepts an electron or hydrogen atom to form a stable DPPH-H compound, which changes its methanol (or ethanol) solution from dark purple to yellow, and the degree of discoloration is quantitative with respect to the number of electrons it accepts (radical scavenging activity), so that rapid quantitative analysis can be performed using a spectrophotometer. Therefore, the present invention evaluates the efficacy of example eight pairs of DPPH radical scavenging results.

Preparing a solution:

weighing 4mg of DPPH free radical powder into a 100mL volumetric flask, dissolving with absolute ethyl alcohol, diluting to a constant volume, and shaking up to obtain 0.04mg/mL DPPH solution.

And (3) taking a 96-well plate, dropwise adding 100 mu L of LDPPH solution, then respectively adding 100 mu L of the eighth example and the second comparative example, uniformly mixing, carrying out a light-shielding reaction for 20min at room temperature, and measuring the ultraviolet absorbance (B) at 515nm, wherein the results are shown in Table 4.

Test example five evaluation tests for efficacy of improving eyesight

The protective effect of example one and example two on BV2 microglia was tested by stimulating BV2 microglia with lipopolysaccharide (1. mu.g/mL), hydrogen peroxide (1mmol/L and 20. mu. mol/L) and blue light (irradiation time 35min) and testing the viability of the cells by MTT method.

MTT method: the detection principle is that succinate dehydrogenase in mitochondria of living cells can enable exogenous MTT to be reduced into water-insoluble blue-violet crystal Formazan (Formazan) and deposited in the cells, and dead cells do not have the function. Dimethyl sulfoxide (DMSO) can dissolve formazan in cells, and an enzyme linked immunosorbent assay detector is used for measuring the light absorption values at 492nm and 630nm wavelengths, so that the quantity of living cells can be indirectly reflected. Within a certain range of cell number, MTT crystals are formed in an amount proportional to the cell number.

Adding 90 μ L of cell sap into 96-well plate with cell density of 5 × 104Per mL, 37 ℃, 5% CO2Incubation is carried out for 24 h; adding 10 μ L (1:10) of each of the first and second examples into each well, and stimulating in different ways after 1h (irradiating with lipopolysaccharide, hydrogen peroxide and blue light); adding 20 mu L MTT solution into each hole after 2h, and continuing culturing for 4 h; terminating the culture, adding 100 mu L of isopropanol hydrochloride to dissolve formazan, and incubating for 10 min; measuring the optical density value (OD value) of each hole at the wavelength of 492nm and 630nm on an enzyme-linked immunosorbent detector; the cell viability was calculated and the results are shown in table 5.

As can be seen from tables 5-3a, the survival rate of the cells is the highest when the first example is 1.0mg/mL, and the cells are protected after being added with the drug, compared with the group irradiated with blue light (see figure 13).

Tables 5-3b blue light stimulation BV2 cell viability assay results (example two)

As can be seen from tables 5-3b, the survival rate of the cells is the highest when the second example is 1.0mg/mL, and compared with the group irradiated with blue light (see FIG. 13), the cells are protected after the drug is added.

In conclusion, the second example has better protection effect than the first example, and not only can maintain the normal proliferation of BV2 cells, but also can maintain the normal activity of the cells.

Then, the effect of improving eyesight of example four was evaluated, and the results of the test using the MTT method (blue light irradiation for 15min) were shown in table 6.

As can be seen from table 6, the protective effect (from large to small) of the herbal extract on blue light stimulation of BV2 cells:

dendrobe, lycium ruthenicum, liquorice, mint and water chestnut

The twelve examples were prepared by selecting 5 kinds of the most effective herb extracts according to the above results, and the results of the test using the MTT method (blue light irradiation for 15min) were shown in Table 7, compared with the three examples.

TABLE 7 blue light stimulation BV2 cell viability assay results (example twelve and example three)

As can be seen from Table 7, the blue light-resisting effect of example three was superior to that of example twelve, and it can be concluded that the example three liposome used in the present invention was the most preferable.

Test example six products sensory and Effect test

Two types of common eye creams are sold in the market as a control group by taking the eleventh example as an experimental group. Volunteers (25-55 years old) male and female 15 persons each were selected, and were randomly and equally divided into 3 groups, and the experimental group and the control group were applied to the face after cleaning the skin every day, and the effect was observed after 15 days. The different items were scored according to the change in skin condition (0-100 points), and the results are shown in Table 8 below.

TABLE 8 Scoring results for different items

EXAMPLE eleven Control group one Control group two
Permeability of 85.67±3.06 81.83±1.61 87.67±2.52
