Abstract

The invention discloses a preparation method of a rhizoma dioscoreae nipponicae bone spur tablet. According to the preparation method disclosed by the invention, effective components in medicinal materials in a prescription are extracted by adopting a diaphragm filter press circulation, extraction and separation integrated technology instead of a percolation method or a decocting method, thus a process flow can be simplified, the production period is greatly shortened, the energy consumption is reduced, environmental protection and utilization of waste residue are facilitated, the consumptionof ethanol as an extraction solvent can be reduced, and the recovery rate of the effective components can be greatly improved.

Description

technical field [0001] The invention belongs to the field of pharmacy and relates to a preparation method of a traditional Chinese medicine preparation. Background technique [0002] Chinese Pharmacopoeia 2010 Edition, Part One records: Chuanlongguci Tablet has the effects of tonifying kidney and bone, promoting blood circulation and relieving pain. It is clinically used for osteoarthritis caused by kidney deficiency and blood stasis, and the symptom is joint pain. The prescription is 270g of pangolin, 324g of epimedium, 432g of dog ridge, 432g of Sichuan achyranthes bidentata, 270g of rehmannia glutinosa, and 162g of medlar. The preparation method is to crush the pangolin, take 180g of fine powder for later use; use 70% ethanol as a solvent for the remaining pangolin powder, percolate, collect 600ml of the percolation liquid, recover the ethanol and concentrate it to a relative density of 1.20-1.25 (70°C); Add water and decoct the rest of Epimedium and other five flavors f...
