Problems solved by technology

3) Change the preparation process, such as making the drug powder into granules before filling; or coating the prepared drug granules or pellets with a film coating to reduce their hygroscopicity, but the coating technology requires special equipment. And it will increase the raw materials and operation steps used in the whole process, thereby increasing the corresponding production cost
For the Hypericum perforatum extract commonly used in the market and the extract prepared by the conventional extraction process, due to its complex composition, easy to absorb moisture and agglomerate, the disintegration time of the prepared hard capsule is unstable and the disintegration time is too long. problem, the present inventors researched capsules containing Hypericum perforatum extract

Embodiment 1

[0091] Embodiment 1: Conventional technology and technology of the present invention pilot scale comparative research

[0092] Raw materials: Hypericum perforatum extract was prepared according to the preparation process of Hypericum perforatum extract described in Experiment 1. The properties and quality inspection results of the Hypericum perforatum extract: dark brown or tan fine powder, special gas, bitter taste, moisture ≤ 5.0%, hypericin ≥ 0.3%; hypericin ≥ 3%; according to Experiment 1 The preparation process of the Acanthopanax senticosus extract is prepared to obtain the Acanthopanax senticosus extract. The properties and quality testing results of the Acanthopanax senticosus: its water content is ≤5.0%, and isoferidin is ≥0.05%. The detection method is the same as before.

[0093] preparation:

[0094] Prepared according to a conventional process, get the above-mentioned Hypericum perforatum extract 33780g and Acanthopanax acanthopanax extract 11140g and appropria...

Embodiment 2

[0104] Example 2: Capsules were prepared using different batches of perforatum extract powder

[0105] Raw materials: Hypericum perforatum extract was prepared according to the preparation method in Experiment 1, and 2 batches were produced, the batch numbers were 100210 and 110303 (the test results of both batches were: moisture ≤ 5.0%, hypericin ≥ 0.3%; Hypericum perforatum Peach element ≥ 3%, the test method is the same as before). Acanthopanax acanthopanax extract was prepared according to the preparation method in Experiment 1, batch number 110605 (test results: moisture ≤ 5.0%, isoferidin ≥ 0.05%, the test method was the same as before).
