2.2.1 Sample compounding
The cortex moutan extract obtained in 1.2, the red ginseng rootlet extract obtained in 1.3 and the ganoderma lucidum fruiting body extract obtained in 1.4 are mixed and compounded according to the proportion shown in Table 6, and DPPH free radical scavenging capacity is used as an index for evaluating the compounding effect. Table 6 shows the results of the complex proportion design by the uniform design formula design method, and the complex proportion was analyzed by calculating the degree of synergy and the equivalent surface model in parallel.
TABLE 6 Compound Table (volume fraction) for each single extracted sample
2.2.2 Determination of the DPPH radical scavenging Capacity of the Compound sample
And 2.1.1.
2.2.3 Complex sample synergy calculation
Some compounds have weaker activity in a single state and have stronger antioxidation effect in a mixed state, namely positive synergistic effect, namely synergistic effect for short, exists among the components. Such as VE and VC. The analysis method of the antioxidant synergistic effect at present is mainly used for researching pharmacodynamics in the medicine field, and comprises a simple effect addition model, an independent model, an isoradiometric analysis method and a response surface method. The method is used for analyzing the synergy degree of the compound sample.
The DPPH radical scavenging ability measurement IC50 values of the samples described in 2.1.1 and 2.2.2 are expressed as the amount of VC with equal effect. The Theoretical Antioxidant Capacity (TAC) of the composite sample is related to the single antioxidant capacity, and the calculation formula is as follows:
TAC=Wa×Ta+Wb×Tb+Wc×TC
In the formula, T a、Tb、TC represents antioxidant capacity (TE) of the same fixed dose of cortex moutan extract, ganoderma lucidum fruiting body extract and Ginseng radix Rubri extract, and W a、Wb、Wc represents weight (%) of antioxidant capacity of equivalent dose of single component of cortex moutan extract, ganoderma lucidum fruiting body extract and Ginseng radix Rubri extract in the compound sample.
The Synergistic Effect (SE) is the ratio of the actual effect to the theoretical effect.
Synergistic effects are exhibited when SE is greater than 1; SE is antagonistic when less than 1.
And independent sample T-test using SPSS 26.
2.2.4 Equivalent surface construction
The equivalent surface was constructed with reference to the concentration sum (Concentration Addition, CA) model in the chemical combination toxicity model. Mathematically, the CA model is expressed as:
where n is the component number of the mixture, C i is the concentration of component i in the mixture that produces an effect of x%, and EC x,i is the concentration of component i alone that causes an effect of x%.
After the construction of the equivalent surface is completed, multiplying the proportion of each compound sample by the IC50 value of the corresponding sample to obtain the corresponding scattered point coordinates of each sample. On both sides of the plane, one side including the origin of the coordinate system is defined as the lower plane, and the other side is defined as the upper plane. If the data points are below the plane, the compound sample is shown to generate a synergistic effect; the data points represent a compound sample composite CA model on a plane; the data points represent the antagonism on a plane.
2.2.5 Data statistics
All experiments were repeated at least three times, IC50 values were measured as a linear fit, and the Theoretical (TAC) and actual (EAC) values were analyzed for significance using independent sample T-test, p <0.05 indicated a statistical difference, p <0.01 indicated a significant statistical difference, and p <0.001 indicated a very significant statistical difference.

And 2.1.3.
2.3 Experimental results
2.3.1 Activity measurement of Single oil extract
The clearance of DPPH radicals was linearly fitted according to the concentrations of the samples to obtain IC50 values of the samples. The IC50 values for samples G1#, G2#, and G3# are summarized in Table 7. The DPPH free radical scavenging ability of three single extracted samples is relatively close, the effect is obvious, and the effect is better by taking the DPPH free radical scavenging ability as a compound assessment index.
The clearance of ABTS radicals was linearly fitted according to the different concentrations of the sample to obtain the IC50 values of the sample. The IC50 values for samples G1#, G2#, and G3# are summarized in Table 7. ABTS free radical reducing ability of cortex moutan extract > Ginseng radix extract > Ganoderma extract. However, the three have lower ABTS radical reduction capability than DPPH radical scavenging capability.
Because the elastase measurement system is a water-soluble system, the oil system cannot effectively detect, 95% ethanol is used for replacing oil, the same raw materials are extracted by the same extraction process, and H1#, H2#, H3# samples are obtained, so that the elastase inhibition capacity of the G1#, G2#, G3# samples is simulated and detected equivalently.
Linear fitting was performed on the inhibition rate of elastase according to the different concentrations of the sample to obtain IC50 values of the sample. The IC50 values for h1#, h2#, h3# samples are summarized in table 7. The elastase inhibition ability of Ganoderma lucidum extract > cortex moutan extract > Ginseng radix extract.
Table 7G# sample antioxidant capacity IC50 value
/>
A comparison of the activities of extracts of a single plant is shown in FIG. 3. In summary, the activities of three oil extracts of ganoderma lucidum, ginseng and peony are as follows: DPPH radical scavenging ability > ABTS radical reducing ability > elastase inhibiting ability. Specifically, the DPPH free radical scavenging ability of the three oil extracts is similar; ABTS radical reducing ability: peony extract > ginseng extract > ganoderma lucidum extract; elastase inhibition ability: ganoderma lucidum extract > peony extract > ginseng extract. Furthermore, the results of the elastase inhibition ability measured for each sample extracted with 95% ethanol do not fully represent the elastase inhibition ability of each oil extract. Therefore, the three oil extracts have optimal DPPH free radical scavenging effect, and finally the DPPH free radical scavenging capacity is measured as an antioxidant capacity evaluation index of the compound sample to perform optimal formula optimization. In FIG. 3, the left Y-axis (0.55-0.75) is the DPPH radical scavenger IC50 value of D-G1#, D-G2#, D-G3#, i.e., to the left of the dashed line; the right Y-axis (0-160) is the ABTS radical scavenger, elastase inhibition IC50 value for A-G1#, A-G2#, A-G3#, H1#, H2#. D-G1# represents DPPH radical scavenging ability of peony extract; A-G1# represents the ABTS free radical reducing ability of peony extract; h1# represents elastase inhibitory ability of peony extract. G2# and H2# are Ginseng radix extract, and G3# and H2# are Ganoderma extract.

Theoretical values and synergy were calculated and the results are shown in table 8. Wherein the highest degree of synergy of K2# is 2.535; k1# synergy was 2.236, which differed by 0.299, and both were significantly different.
Table 8 summary of theoretical values and synergy of samples
Note that: * : p <0.05, indicating a statistical difference; * *: p <0.01, indicating significant statistical differences; * **: p <0.001 indicates a very significant statistical difference.
2.3.4 Equivalent facets
The equivalent surface equation is constructed according to the CA model as follows:
Wherein x is the G1 sample concentration (%); y is G2 sample concentration (%); z is G3 sample concentration (%).
The equivalent surfaces are shown in fig. 6-8. On a plane formed by points G1#, G2#, and G3#, the point of the compound sample below the plane is denoted as a synergistic effect, the point above the plane is denoted as an antagonistic effect, and the point falling within the plane is denoted as a summation effect.
As shown in the following figures, k1# -k5# shows a synergistic effect below the plane, k6# is antagonism, and k7# is additive effect. Approximately the same as the synergy calculation result. K1# is similar to K2# in color, and the degree of synergy is comparable.
Therefore, in all the combinations, the highest degree of synergy of the combination K2# is 2.535, and the corresponding combination proportion is 50% of peony oil extract, 45.8% of ginseng oil extract and 4.17% of ganoderma lucidum oil extract; the combination k1# synergy, second, was 2.236, which was 0.299 different from k2# (k1# and k2# were not statistically different in synergy). K1# and k2# have significant differences in antioxidant capacity compared to a single sample.
2.3.5 Elastase inhibition ability of the Compound sample
The results of testing the elastase inhibitory abilities of the k1# and k2# samples show that the elastase inhibitory abilities of the k1# and k2# samples have significant differences in fig. 9. The difference in elastase inhibitory abilities between the k1# and k2# samples was large, and the elastase inhibitory ability between the k1# samples was large, as shown in fig. 9: p <0.05, indicating a statistical difference; * *: p <0.01 indicates significant statistical differences. The elastase inhibitory capacity of each single sample versus the formulated sample versus, for example, that shown in fig. 10, it can be seen that there is no significant difference in the elastase inhibitory capacity of the formulated sample versus the single sample.
