Embodiment 1
[0040] A preparation method of Jieyu Shunxin Tablets, comprising the following steps:
[0041] Step 1: Raw material preparation: 40 parts of Salvia miltiorrhiza, 8 parts of Bupleurum, 4 parts of Coptis chinensis, 12 parts of turmeric, 8 parts of polygala, 8 parts of Shichangpu, 12 parts of keel, 12 parts of oyster, and 12 parts of green stone;
[0042] Step 2: Alcohol extraction: mix the raw materials in step 1 and add an ethanol solution with a concentration of 80%, extract 3 times, each ethanol extraction time is 1.5h, and the extraction temperature is 75°C. After the extraction is completed, the The extract is filtered through a 200-mesh sieve, and the filter residue is discarded;
[0043] Step 3: extract extract: Concentrate the filtrate obtained in step 2 to an extract with a relative density of 1.25 under reduced pressure. The conditions for concentration under reduced pressure are: the degree of vacuum is -0.08MPa, the steam pressure is not greater than 0.04MPa, and the t...
Embodiment 2
[0048] A preparation method of Jieyu Shunxin Tablets, comprising the following steps:
[0049] Step 1: Raw material preparation: 20 parts of Danshen, 4 parts of Bupleurum, 2 parts of Coptis chinensis, 8 parts of turmeric, 4 parts of polygala, 4 parts of Shichangpu, 8 parts of keel, 8 parts of oyster, and 8 parts of green stone;
[0050] Step 2: Alcohol extraction: Mix the raw materials in step 1 and add ethanol solution with a concentration of 60%, extract 3 times, each ethanol extraction time is 1h, and the extraction temperature is 65°C. After the extraction is completed, extract The liquid is filtered through a 200-mesh sieve, and the filter residue is discarded;
[0051] Step 3: extract extract: Concentrate the filtrate obtained in step 2 to an extract with a relative density of 1.2 under reduced pressure. The conditions for concentration under reduced pressure are: the degree of vacuum is -0.06MPa, the steam pressure is not greater than 0.04MPa, and the temperature is 70°...
Embodiment 3
[0056] A preparation method of Jieyu Shunxin Tablets, comprising the following steps:
[0057] Step 1: Raw material preparation: 30 parts of Salvia miltiorrhiza, 6 parts of Bupleurum, 3 parts of Coptis chinensis, 10 parts of turmeric, 6 parts of polygala, 6 parts of Shichangpu, 10 parts of keel, 10 parts of oyster, 10 parts of green stone;
[0058] Step 2: Alcohol extraction: mix the raw materials in step 1 and add a 70% ethanol solution, extract 3 times, each ethanol extraction time is 1.25h, and the extraction temperature is 70°C. After the extraction is completed, the The extract is filtered through a 200-mesh sieve, and the filter residue is discarded;
[0059] Step 3: extract extract: Concentrate the filtrate obtained in step 2 to an extract with a relative density of 1.23 under reduced pressure. The conditions for concentration under reduced pressure are: the degree of vacuum is -0.07MPa, the steam pressure is not greater than 0.04MPa, and the temperature is 70°C;
