preparation example Construction

[0087] The raw materials for preparing Yigan Shukang Capsules are: 10-15 parts by mass of Phyllostachys phylloxera, 15-20 parts by mass of Salvia Miltiorrhiza, 15-20 parts by mass of Hedyotis diffusa, 15-20 parts by mass of Astragalus, 15-20 parts by mass of Polygonum multiflorum, Polygonum cuspidatum 15-20 parts by mass, the sum of the parts by mass of raw materials is 100 parts. Its preparation method comprises the following steps:

[0088] Step 1: take Astragalus membranaceus, decoct and extract twice, combine the extracts, filter, and use the dregs for later use, concentrate the filtrate under reduced pressure to a thick paste, and dry it in vacuum to form a fine powder A;

[0089] Step 2: Add the dregs of Step 1 to the herbs of Phyllostachys phylloxera, Salvia, Hedyotis diffusa, Polygonum cuspidatum and Polygonum multiflorum, extract twice with ethanol under reflux, combine the extracts, filter, and recover the ethanol from the filtrate under reduced pressure and concentr...

Embodiment

[0098] The components of Yigan Shukang Capsules in this example are: Phyllostachys foliage 322g, Salvia miltiorrhiza 600g, Hedyotis diffusa 460g, Radix Astragali 460g, Polygonum multiflorum 460g, Polygonum cuspidatum 460g; After purification, they are divided into two groups, which specifically include the following steps:

[0099] Step 1: Take Radix Astragalus and extract twice, add 10 times the amount of water for the first time, add 8 times the amount of water for the second time, each time for 2 hours, combine the two extracts, filter, and set aside the dregs, the filtrate is at -0.04 Mpa, concentrated under reduced pressure at 70°C to a thick paste with a relative density of 1.35-1.45 (60°C), dried in vacuum to fine powder A;

[0100] Step 2: Add the dregs of step 1 to the medicinal materials of Phyllostachys phylloxera, Danshen, Hedyotis diffusa, Polygonum cuspidatum and Polygonum multiflorum, add 70% ethanol to reflux and extract twice, add 12 times the amount for the f...

Abstract

The invention discloses a preparation method of Yigan Shukang Capsules. Firstly, astragalus is extracted with water, the extract is concentrated and dried into fine powder A, and the dregs are combined with phylloxera, salvia miltiorrhiza, hedyotis diffusa, polygonum cuspidatum and fleece-flower root, and 70% Extract with ethanol, concentrate and dry the extract into fine powder B, mix fine powder A and fine powder B evenly, granulate in one step, and pack into capsules to obtain Yigan Shukang Capsules. The present invention adopts group extraction, which can enrich the active ingredients, thereby improving the curative effect of the product and reducing the dosage. Compared with the original process group, the Yigan Shukang Capsules prepared by the method of the present invention can reduce the dosage by 20%. The effect of inhibiting the expression of HBsAg and HBeAg in HepG2-2.2.15 cells and the protective effect on chronic liver injury (CCl4 model) are still stronger than the original process.

Description

technical field [0001] The invention belongs to the technical field of preparation of Chinese patent medicines, and in particular relates to a preparation method of Yigan Shukang capsules.
