Example Embodiment

[0050] Example 1
[0051] An astragalus injection containing the following ingredients:
[0052] Each 10000ml injection contains,
[0053] Astragalus extract 6000ml;
[0054] Polysorbate-8080g;
[0055] Add water for injection to 10000ml.
[0056] The preparation process of the above-mentioned astragalus injection includes the following steps:
[0057] (1) Extract astragalus extract, weigh the raw materials according to the formula:
[0058] (2) Filter the astragalus extract with a titanium rod, boil the filtrate for 5 minutes and cool;
[0059] (3) After the solution of step (2) is pre-filtered through micropores, and then through micropore ultrafiltration, after the ultrafiltration is completed, rinse the residual liquid in the column with an appropriate amount of water for injection, and merge it with the previous filtrate;
[0060] (4) Add polysorbate-80 to the filtrate obtained in step (3) and stir evenly, and adjust the pH value to 7.8-8.0 with 20% NaOH;
[0061] (5) Add water for injection to the solution obtained in step (4) to the total amount, and stir evenly;
[0062] (6) Filter the solution obtained in step (5) with a 0.45μm pleated filter element into the control bottle before potting;
[0063] (7) Potting the filtrate obtained in step (6), pass N during potting 2;
[0064] (8) Sterilize the product obtained in step (7) within 4 hours after the completion of step (7), with a sterilization temperature of 115°C and a sterilization time of 30 minutes.

[0071] Add water for injection to 10000ml.
[0072] The preparation process of the above-mentioned astragalus injection includes the following steps:
[0073] The following test steps are carried out according to the aseptic production process,
[0074] (1) Extract astragalus extract, weigh the raw materials according to the formula:
[0075] (2) Filter the astragalus extract with a titanium rod, boil the filtrate for 5 minutes and cool;
[0076] (3) After the solution of step (2) is pre-filtered through micropores, and then through micropore ultrafiltration, after the ultrafiltration is completed, rinse the residual liquid in the column with an appropriate amount of water for injection, and merge it with the previous filtrate;
[0077] (4) Add polysorbate-80 to the filtrate obtained in step (3) and stir evenly, and adjust the pH value to 7.8-8.0 with 20% NaOH;
[0078] (5) Add water for injection to the solution obtained in step (4) to the total amount, and stir evenly;
[0079] (6) Filter the solution obtained in step (5) through 0.45μm and 0.22μm pleated filter elements into the control bottle before potting;
[0080] (7) Potting the filtrate obtained in step (6), pass N during potting 2.

Example Embodiment
