Assay 1VEGF Activity assay
VEGF (vascular endothelial growth factor) activity was measured by ELISA kit. The detection steps are as follows:
(1) Blank group 100. Mu.L of Ham's F-12K medium containing 10% fetal bovine serum and Human Umbilical Vein Endothelial Cells (HUVEC) were inoculated in 96-well plates at a density of 1X 10 4 cells per well, cultured at 37 ℃ for 24 hours under 5% CO 2, then replaced with serum-free medium, cell culture supernatant was collected, and the secretion level of VEGF in HUVEC was detected by ELISA detection kit;
(2) A negative control group, which was inoculated with 100. Mu.L of Ham's F-12K medium containing 10% fetal bovine serum and Human Umbilical Vein Endothelial Cells (HUVEC) at a density of 1X 10 4 cells per well in a 96-well plate, cultured at 37℃for 24 hours under 5% CO 2, and then replaced with serum-free medium, irradiated with 15mJ/cm 2 UVB, and cultured for 24 hours, and cell culture supernatants were collected to examine the level of VEGF secretion in UVB-induced HUVECs;
(3) Experimental group 100. Mu.L of Ham' sF-12K medium containing 10% fetal bovine serum and Human Umbilical Vein Endothelial Cells (HUVEC) were inoculated in 96-well plates at a density of 1X 10 4 cells per well, cultured at 37℃for 24 hours in 5% CO 2, and then replaced with serum-free medium, 200. Mu.L of each composition solution was added (preparation of composition solution: 50mg of each composition was taken and 5mL of deionized water was added to dissolve completely to obtain composition solution), and the culture was continued for 24 hours by irradiation with 15mJ/cm 2 UVB, and cell culture supernatants were collected to measure the secretion level of VEGF in HUVEC.
The results of the VEGF secretion level (%), average.+ -. Standard deviation) assays for each group are shown in Table 2.
TABLE 2
In table 2, "/" indicates that there is no description of technical effects.
In Table 2, the negative control group had a significant difference (## P < 0.01) from the blank group, indicating that treatment with 15mJ/cm 2 UVB irradiation can increase VEGF activity, cause vasodilation and increase vascular permeability. The experimental group had a significant difference (△P<0.05,△△ P < 0.01) compared to the negative control group, indicating that the composition had the technical effect of reducing UVB-induced VEGF secretion in HUVEC.
The comparative example group showed a significant difference (&P<0.05,&& P < 0.01) from the example 1 group, indicating that the compositions of examples 1-7 were more effective than the comparative example group, and the compositions of examples had more excellent vascular dilation-reducing and VEGF secretion-inhibiting effects. Wherein the composition of comparative example 1 contains only palmitoyl tea extract, composite plant extract a and composite plant extract B, the composition of comparative example 2 contains only bilberry leaf extract and 2 components of Sphingomonas fermentation product extract, and the compositions of comparative example 1 and comparative example 2 can reduce VEGF activity, but the technical effects are weaker, and even if the VEGF activity reducing effects of comparative example 1 and comparative example 2 are added, the effects described in the examples cannot be achieved, so that the components of the composition of the present invention interact with each other, and the synergistic technical effects are brought about. Comparative example 4-comparative example 5 the replacement of some of the components in the composition with conventional soothing skin components, which effect is significantly different from that of the examples, which have a better effect of reducing VEGF secretion levels, indicates that the components in the composition of the present invention are not optionally replaced, that the choice of components is not conventional, and that the composition of the present invention brings unexpected technical effects. Comparative example 6 the effect of reducing the level of VEGF secretion by changing the weight ratio of each component in the composition was still inferior to that of comparative example 7 in which the preparation of bilberry leaf extract was performed using pectinase, the resulting composition was significantly reduced in the effect of reducing the level of VEGF secretion.
Test 2 Rat Basophil (RBL) histamine release test
Histamine is a substance released when cells are subjected to external stimulus and anaphylaxis, and the release of histamine leads to increased permeability of tissue wall, resulting in tissue edema and skin itching. The efficacy of the test compositions in relieving itching, soothing, repairing skin was assessed by measuring histamine release levels in RBL-2H3 cells.
The experimental method comprises collecting RBL-2H3 cells in logarithmic phase, inoculating 2.0-3.0X10 5 cells/mL/hole into 24-well plate, culturing in incubator for 18-24H, washing cells twice with HBSS buffer, adding DNP-IgE (immunoglobulin E) to the rest groups except blank control group to make its final concentration 1 μg/mL, and culturing in incubator for 24H to promote sufficient expression of high affinity receptor Fc epsilon RI on RBL-2H3 cell surface, washing cells twice with HBSS buffer, adding 100 μl of reagent, and using the following reagents:
The reagent for sample group is prepared by respectively taking 100mg of each composition, adding 5mL of DMSO for full dissolution to prepare a DMSO stock solution with the concentration of 2%, and then sequentially diluting to 1.0% by using a serum-free MEM culture medium;
the blank group uses a reagent, namely a serum-free MEM culture medium;
the model control group uses a reagent, namely a serum-free MEM culture medium;
3 wells per group were incubated for 1H, the cells were washed twice with HBSS, then HBSS (Hank's balanced salt solution) containing DNP-BSA at 0.5. Mu.g/mL was added to activate RBL-2H3 to release histamine, the reaction was stopped by ice bath for 10min after incubation for 1.5H, the supernatant was collected, stored at-80℃and the histamine content (ng/mL) was determined using ELISA kit.
The calculated formula of the histamine inhibition ratio is that the histamine inhibition ratio (%) = (histamine content M-histamine content TA)/(histamine content M-histamine content NT) ×100%.
The results of histamine content and histamine inhibition for each group are shown in Table 3.
TABLE 3 Table 3
In table 3, "/" indicates that there is no description of the effect of the related art.
In table 3, the model control group showed a significant difference in histamine content (## P < 0.01) compared to the blank group, indicating that the histamine release model was successfully prepared. The compositions of the examples of the present invention all significantly inhibited RBL-2H3 histamine release, the examples set had better inhibition than the comparative examples set, and the comparative examples each had significant differences in histamine inhibition (△△ P < 0.01) compared to example 1.
The comparison of the histamine inhibition rate data of comparative examples 1 and 2 and example 1 shows that the components in the composition of the present invention interact with each other to generate a synergistic effect, and the histamine inhibition rate data of comparative examples 3 and 4 and example 1 show that the effect of remarkably improving the histamine inhibition rate of the present invention cannot be achieved even if the components in the composition are replaced with other components with similar effects, and the technical effects of comparative examples 3 and 4 after the components are changed are remarkably reduced. Comparative example 6 the histamine inhibition rate was significantly reduced compared to example 1 after changing the weight ratios of the components of the composition, indicating that the specific ratios of the components in the composition provide significantly improved technical results.
