[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.
