Embodiment 1
[0024] Example 1: Investigation of Pueraria daidzein-7,4'-sodium dioxoacetate and DZ5 saturated solubility in water
[0025] Take three parts each of excessive daidzein-7,4'-dioxoacetate and DZ5, put them into 10ml plugged centrifuge tubes, add 10ml of distilled water, put the above centrifuge tubes at 25°C, 60r / min in a constant temperature water-bath shaker, after shaking for 24 hours, take it out at the designated time point, centrifuge, absorb an appropriate amount of supernatant, filter it through a 0.45 μm microporous membrane, discard the initial filtrate, and then dilute it with distilled water. The peak area was determined by high performance liquid phase analysis method, and substituted into the standard curve to obtain the concentration. The results are shown in Table 1.

Embodiment 2
[0028] Embodiment 2: Determination of the range of the pH value of the medicinal solution
[0029] The pH value of human plasma is 7.4, and the pH range of commonly used infusion solutions is 3.2-8.5. In order to determine the pH value range of this product, the pH value range of this product is designed to be 5.0-8.5, and the stability of the liquid medicine is investigated. According to the preparation process, prepare daidzein-7,4'-dioxoacetate sodium, DZ5 solution with a specification of 600mg: 100ml, and adjust the pH to 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0 and 8.5 after equalization , Sterilize at 121°C for 15 minutes, investigate the stability before and after sterilization, and determine its suitable pH. The results are shown in Table 2.

[0033] Conclusion: Pueraria daidzein-7,4'-dioxoacetate sodium is stabl...
Embodiment 3
[0034] Embodiment 3: Influence of filling nitrogen or not on infusion stability during filling
[0035]According to the preparation process, prepare daidzein-7,4'-dioxoacetate sodium infusion with specifications of 600mg: 100ml, adjust isotonicity with sodium chloride, adjust pH to 7.5 with sodium hydroxide, divide into two parts, one part Nitrogen gas is filled during filling, and no nitrogen gas is filled when one portion is filled, sterilized at 121°C for 15 minutes, placed under high temperature and accelerated light conditions for 10 days, and the appearance of each trial product is observed. The results are shown in Table 3.
[0036] Influence of Nitrogen Filling on Infusion Stabilizers during Table 3 Filling
[0037]
[0038] Conclusion: Pueraria daidzein-7,4'-dioxoacetate sodium is stable for 10 days under the condition of nitrogen filling, high temperature and accelerated light.
