1-1. Process
Dimethyl sulfoxide (DMSO) is used as a solvent to prepare test samples with different concentrations of apigenin and luteolin. Tests were run in 9 batches, batch 1 to batch 9. There were 6 independent trials in each batch of trials.
In each independent experiment, the inhibition rate of the specific concentration of apigenin test sample and the specific concentration of luteolin test sample on the keratinocyte proliferation is determined, and the inhibition rate of the combination of the specific concentration of apigenin test sample and the specific concentration of luteolin test sample on the keratinocyte proliferation is determined. Between the independent experiments, the concentration of the apigenin test sample is different, the concentration of the luteolin test sample is also different, and the molar ratio or the weight ratio of the apigenin test sample to the luteolin test sample is the same.
Also, the molar ratio or the weight ratio of the apigenin test sample to the luteolin test sample is not the same between each batch of tests.
The experimental procedure is as follows:

After overnight culture, the cells in the culture dish were added with the test sample (see Table 1, the cells in the control group were treated with only dimethyl sulfoxide) to co-culture for 48 hours (T48). The supernatant in the culture dish was then removed.
After removing the supernatant, 50. mu.L of MTT solution (0.5 mg/mL; Life Technologies Cat. No. M-6494) was added to the cells, and the culture plate was then placed at 37 ℃ and 5% CO 2 The culture was carried out in an incubator for 1.5 hours. Then, 150. mu.L of DMSO (J.T.Baker, Cat.No.9224-03) was added to the cells in the culture dish and shaken for 5 minutes.
Then, the absorbance at a wavelength of 570nm of each well of the culture dish was measured by a continuous wavelength microplate analyzer, and the cell proliferation inhibition rate was calculated by the following formula
Cell proliferation inhibition rate (T48 control group) 570nm -T48 test groups 570nm ) /(T48 control group 570nm -T0 control group 570nm )。

Example 3
Evaluation of the synergistic Effect of apigenin and luteolin
In this experiment, CalcuSyn software (bios) was used to analyze the synergistic effect of apigenin and luteolin.
The Calcusyn software is a commonly used analysis software for analyzing the drug dose effect of a single drug and a plurality of drugs. Calcusyn software can be used to analyze drug-complexing interactions and automatically quantify various phenomena, such as synergy (synergism) and inhibition (inhibition). Calcusyn software is capable of processing data for individual drugs and combination drugs at either fixed-ratio or non-fixed-ratio (on-constant-ratio) and can evaluate the interaction of the combination drugs by the Combination Index (CI) calculated by the Calcusyn software (Chou and Talalay, adv. enzyme Regul.22:27-55 (1984). the formula for the combination index is as follows:
combination index of C1/IC1+ C2/IC2
C1 and C2 are the respective concentrations of the first compound and the second compound, respectively, at which 50% (or 75%, or 90%) of their activity for a particular physiological or medicinal purpose is measured when the first compound and the second compound are assayed in combination; IC1 and IC2 are the respective concentrations of the first compound and the second compound, respectively, at which 50% (or 75%, or 90%) of the activity of the first compound and the second compound for a particular physiological or medicinal purpose is achieved when the first compound and the second compound are analyzed independently.
A combination index of less than 1 indicates that the two compounds have a synergistic effect (synergistic effect) for a particular physiological or medicinal purpose, a combination index of 1 indicates that the two compounds have an additive effect (additive effect) for a particular physiological or medicinal purpose, and a combination index of greater than 1 indicates that the two compounds have an antagonistic effect (antagonistic effect) for a particular physiological or medicinal purpose (Ting-Chao Chou; Cancer Res; 70(2) January15,2010).
3-1 evaluation of synergistic Effect of apigenin and luteolin on inhibition of skin cell proliferation
3-1-1. Process
The test results of 9 batches shown in table 1 in example 1 were analyzed by Calcusyn software, respectively, to calculate respective combination indices of apigenin and luteolin in different ratios for inhibiting skin cell proliferation.
3-1-2. results
The respective combination indices of apigenin and luteolin combined in different ratios for inhibiting skin cell proliferation calculated by Calcusyn are shown in table 3 below.
TABLE 3
Figure BDA0002469040350000151
Figure BDA0002469040350000161
As can be seen from Table 3, when the molar ratio of apigenin to luteolin is 2-10:1, apigenin and luteolin have synergistic effect in inhibiting skin cell proliferation. In contrast, when the molar ratio of apigenin to luteolin is 1:1, 20:1 or 1:2-20, apigenin and luteolin do not have a synergistic effect on inhibiting skin cell proliferation and even produce an antagonistic effect.
3-2 evaluation of the synergistic Effect of apigenin and luteolin on anti-inflammation
3-2-1. Process
The test results of 9 lots shown in table 2 in example 2 were analyzed by Calcusyn software, respectively, to calculate respective combination indices of apigenin and luteolin at different ratios for anti-inflammation.
3-2-2. results
The respective combination indices of apigenin and luteolin combined in different ratios for anti-inflammation, calculated by Calcusyn, are shown in Table 4 below.

As can be seen from Table 4, when the molar ratio of apigenin to luteolin is 2-20:1, apigenin and luteolin have synergistic effect on anti-inflammation. In contrast, when the molar ratio of apigenin to luteolin is 1:1 or 1:2-20, apigenin and luteolin do not have a synergistic effect on anti-inflammation and even produce an antagonistic effect.
3-3. conclusion
From the above results, it is clear that, in the inhibition of skin cell proliferation or anti-inflammatory apigenin and luteolin, apigenin and luteolin in any combination ratio do not have a synergistic effect, but the apigenin and the luteolin in a specific combination ratio have to have a synergistic effect. When the molar ratio of apigenin to luteolin is about 2-20:1, apigenin and luteolin can have synergistic effects in inhibiting skin cell proliferation and/or resisting inflammation.
Although the present invention has been described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
