preparation example Construction

[0037] This embodiment also provides a preparation method of a pharmaceutical composition, which includes:

[0038] Step S1: Mix 360-390 parts by weight of celandine, 360-390 parts by weight of Pulsatilla chinensis and 360-390 parts by weight of bark peel, and reflux extract with 30-70% (vol%) ethanol solution for 1-2 times , 1-5 hours each time, combined the extracted filtrate and concentrated to obtain the first clear paste.

[0039] In this step, medium-concentration ethanol (30-70% ethanol solution) is used as an extraction solvent to extract the mixture of celandine, Pulsatilla pulsatillae, and Petrium chinensis. The content of the element, thereby improving the efficacy of the drug. At the same time, it can also reduce the content of water-soluble impurities, thereby improving the stability and quality controllability of the medicament.

[0040] Further, 40-60% (vol%) ethanol solution is used for reflux extraction for 1-2 times, each time for 2-3 hours.

Abstract

The invention provides a pharmaceutical composition as well as a preparation method and an application thereof, and belongs to the field of medicines. The pharmaceutical composition consists of the following components in parts by weight: 800-1200 parts of berberine hydrochloride, 1-3 parts of chelerythrine and 300-500 parts of pulsatilla saponin B4. An agent consists of the pharmaceutical composition and a pharmaceutically acceptable carrier or adjuvants. The preparation method of the pharmaceutical composition comprises the following steps: mixing herba chelidonii, Chinese pulsatilla root and cortex fraxini, and implementing reflux extraction by virtue of a 30-70% (vol%) ethanol solution for 1-2 times, wherein each time lasts for 1-5h, combining filtrates which are obtained from the extraction, and condensing the combined filtrate, so that a first clear paste is obtained; and mixing 20-30 parts by weight of berberine hydrochloride with the first clear paste. According to the preparation method, the contents of the chelerythrine, the pulsatilla saponin B4 and aesculin in the extract (the pharmaceutical composition) can be effectively improved, so that the efficacy of the pharmaceutical composition and the agent on treating such diseases as diarrhoea, dysentery and the like can be improved.

Description

technical field [0001] The present invention relates to the field of medicine, in particular to a pharmaceutical composition and its preparation method and use. Background technique [0002] According to traditional Chinese medicine, diarrhea refers to the increase in the frequency of defecation, loose stools, or even watery stools caused by feeling external evils, being injured by diet, or emotional disorders, or weak spleen and stomach, or deficiency of spleen and kidney yang. The main disease syndrome. Dysentery is characterized by increased stool frequency, abdominal pain, tenesmus, red and white sticky dysentery. [0003] At present, traditional Chinese medicine mainly treats such diseases with medicines for clearing heat and detoxification, drying dampness and stopping dysentery. However, due to certain defects in the preparation process, the extraction rate of the effective components in the medicinal materials is low, and the curative effect of the products is not g...
