Abstract

The invention discloses a preparation method of a Bazheng mixture. The preparation method utilizes a diaphragm press filtration cycle extraction separation integrated technology to replace the existing immersion technology, the percolation technology and the decoction technology so as to extract active ingredients from prescription drugs, and thus the preparation method simplifies a process flow,shortens greatly a production period, saves energy consumption, is beneficial for environmental protection and greatly improves a recovery rate of active ingredients. Through adopting ultrafiltrationmembrane direct filtration to replace standing and filtration in preparation steps, the preparation method solves thoroughly the quality problem that a finished product produces precipitates easily and thus the finished product cannot satisfy mixture related requirements wherein the produced precipitates do not disappear through shaking, and shortens further a production period.

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] The Chinese Pharmacopoeia 2010 edition one records: Bazheng Mixture has the effects of clearing away heat, diuresis and relieving stranguria, and it is clinically used for damp-heat injection, short red urine, phlegm, astringent pain, dry mouth and throat. The prescription is 118g Qumai, 18g fried plantain seed, 118g rhubarb, 118g talc, 118g akebia, 118g gardenia, 118g licorice, and 59g rush. The preparation method is to impregnate the plantain seeds with 25% ethanol, and collect the impregnation solution; use 50% ethanol as a solvent for the rhubarb, soak it for 24 hours, then carry out percolation, collect the percolation solution, and recover the ethanol under reduced pressure; Boil three times, filter, combine the filtrate, concentrate the filtrate to about 1300ml, combine with the soaking ...
