The invention discloses a preparation method of a traditional Chinese medicine composition for removing impurities by using a ceramic membrane. Standby; Cicada slough, Scutellaria baicalensis, Dilong, Aster, Baibu, Myrobalan add 60-80% ethanol for reflux extraction, filter, and the alcohol extract is then ultrafiltered with a ceramic membrane, and the filtrate is concentrated; alcohol-extracted medicinal residues and Nepeta medicinal residues , the residual liquid, the silkworms are combined, add water to decoct, filter, the water extract is microfiltered with a ceramic membrane, and the filtrate is concentrated under reduced pressure; the alcohol extract and the water extract are mixed to obtain a thick extract, add dextrin, Vacuum drying, pulverizing the dry extract, supplementing with dextrin, adding an appropriate amount of ethanol solution of the binder, granulating, and drying; adding the inclusion compound to the granules and mixing well. The invention enriches the index component of curative effect baicalin, and can also obviously reduce the ointment yield of the extract. At the same time, the viscosity of the extract is improved, and the preparation is easy to form, and the dissolved solution of the preparation is clear and translucent. |
