Linear fit was performed on the DPPH radical clearance at different concentrations of the samples to obtain IC50 values for the samples. The IC50 values for the G1#, G2#, and G3# samples are summarized in Table 7. The DPPH free radical scavenging capacity of three single extraction samples is relatively close, the effect is obvious, and the effect is better by taking the DPPH free radical scavenging capacity as a compound assessment index.
Linear fits were made for the clearance of ABTS radicals at different concentrations of the sample to obtain IC50 values for the sample. The IC50 values for the G1#, G2#, and G3# samples are summarized in Table 7. The ABTS free radical reducing capability of the moutan bark extract is more than that of the ginseng extract is more than that of the ganoderma lucidum extract. But the ABTS free radical reducing ability of the three is lower than the DPPH free radical scavenging ability.

Specifically, the DPPH free radical scavenging capacity of the three oil extracts is similar; ABTS radical reducing power: peony extract, ginseng extract, ganoderma extract; elastase inhibitory ability: the ganoderma lucidum extract, the peony extract and the ginseng extract. Furthermore, the results of the elastase inhibitory activity measured on each sample extracted with 95% ethanol do not fully represent the elastase inhibitory activity of each oil extract. Therefore, the three oil extracts have the optimal effect of eliminating DPPH free radicals, and the optimal formula optimization is finally carried out by taking the measurement of the DPPH free radical eliminating capacity as an index for evaluating the antioxidant capacity of the compound sample.

The composite and single samples were expressed separately in equal effect VC (how much VC is needed to achieve the same DPPH clearance under the same operating conditions), and the VC equivalent value pairs for the single and composite samples are shown in fig. 5, where: p <0.001 indicates a very significant statistical difference. Theoretical values and degrees of synergy were calculated, and the results are shown in table 8.
