Embodiment 1
[0045] Example 1: Preparation of new Houttuyrin sodium compound
[0046] 1. Prepare 5L of a saturated solution of new Houttuynia sodium crude product at 55°C, stir until completely dissolved;
[0047] 2. In a sound field with a frequency of 25KHz and an output power of 60W, add 50L of a mixed solution of isopropanol and acetone at 5°C while stirring. After the mixed solution is added, stop stirring and continue to cool down under the action of the sound field to 1 When the temperature is ℃, the sound field is stopped, and the crystals are allowed to stand for 24 hours under the condition of 0 ℃. After the crystals are precipitated, they are washed and dried to obtain the new houttuyniacin sodium compound. Wherein, the adding speed of the mixed solution of isopropanol and acetone is: v 1 =500 ml / min; the volume ratio of isopropanol and acetone is 5:1; after the mixed solvent is added, the speed of cooling is v 2 =5°C / hour.

Embodiment 2
[0049] Example 2: Preparation of new houttuyrin sodium compound
[0050] 1. Prepare 5L of a saturated solution of new Houttuyrin sodium crude product at 70°C, stir until completely dissolved;
[0051] 2. In a sound field with a frequency of 20KHz and an output power of 40W, add 10L of a mixed solution of isopropanol and acetone at 0°C while stirring, stop stirring after the mixed solution is added, and continue to cool down under the action of the sound field to 1 When the temperature is ℃, the sound field is stopped, and the crystals are allowed to stand for 24 hours under the condition of 0 ℃. After the crystals are precipitated, they are washed and dried to obtain the new houttuyniacin sodium compound. Wherein, the adding speed of the mixed solution of isopropanol and acetone is: v 1 =100 ml / min; the volume ratio of isopropanol and acetone is 5:2; after the mixed solvent is added, the speed of cooling is v 2 =2°C / hour.

Embodiment 3
[0053] Example 3: Preparation of new houttuyrin sodium compound freeze-dried powder injection
[0054] Formulation: 10 g of the new houttuyniacin sodium compound prepared in Example 1, 20 g of polysorbate-800, 40 g of mannitol, and 0.1 g of meglumine;
[0055] Preparation:
[0056] 1. The polysorbate-80 of the recipe quantity is stirred and dissolved with water for injection at a temperature of 45 ℃, then the new houttuyniacin sodium compound of the recipe quantity is added, and stirring and dissolving; after adding excipient and meglumine, stirring and dissolving to room temperature;
[0057] 2. Adjust the pH value to 5.0-6.0, add medicinal activated carbon with a mass percentage of 0.01%, adsorb for 20 minutes, filter and decarbonize; fine filter, add sterile water for injection to 2500ml, fine filter;
[0058] 3. Freeze-drying: freeze-dry the filtrate obtained in step 2, divide it into 2500 pieces under aseptic conditions, press lid, and seal with aluminum, and then obtai...
