The invention discloses a preparation method of a
traditional Chinese medicine composition for removing impurities by using a
ceramic membrane. The preparation method comprises the following steps: adding water into herba schizonepetae, soaking the herba schizonepetae, heating the herba schizonepetae until the herba schizonepetae is boiled, carrying out heat preservation, collecting volatile oil, preparing an
inclusion compound from the volatile oil, and and subjecting dregs and residual liquid to standing for later use; adding 60-80%
ethanol into
cicada slough, radix scutellariae,
earthworm, radix asteris, radix stemonae and fructus chebulae, performing
reflux extraction and filtering, performing
ultrafiltration on an
alcohol extract by adopting the
ceramic membrane, and concentrating a filtrate; combining
alcohol extraction dregs with fineleaf
schizonepeta herb dregs, residual liquid and stiff silkworms, adding water for decoction, carrying out filtering, performing
microfiltration on water extract by using the
ceramic membrane, and concentrating a filtrate under reduced pressure; mixing the
alcohol extract and the water extract to obtain a thick extract, adding
dextrin, performing
vacuum drying, crushing the dry extract, supplementing the
dextrin, adding a proper amount of an
adhesive, namely an
ethanol solution, performing
granulation, and performing
drying; and adding the
clathrate compound into the particles, and conducting uniform mixing. According to the invention, the index component
baicalin with
curative effect is enriched, and the extract yield of the extract can be obviously reduced. Meanwhile, the
viscosity of the extract is improved, a preparation is easy to form, and a dissolving solution of the preparation is clear and transparent.
