[0039] Example 1
[0040] A preparation method of Jieyu Shunxin Tablets includes the following steps:
[0041] Step 1: Preparation of raw materials: 40 parts of Danshen, 8 parts of Bupleurum, 4 parts of Coptis, 12 parts of Turmeric, 8 parts of Polygala, 8 parts of Shichangpu, 12 parts of keel, 12 parts of oysters, 12 parts of Qingzhushi;
[0042] Step 2: Alcohol extraction: mix the raw materials in step one and add 80% ethanol solution, extract 3 times, each time the ethanol extraction time is 1.5h, the extraction temperature is 75℃, after the extraction is completed The extract is filtered through a 200-mesh sieve, and the filter residue is discarded;
[0043] Step 3: Collecting the paste: Concentrate the filtrate obtained in Step 2 under reduced pressure to an extract with a relative density of 1.25, and the conditions for concentration under reduced pressure are: the vacuum degree is -0.08MPa, the vapor pressure is not greater than 0.04MPa, and the temperature is 70°C;
