Problems solved by technology

In the above method, the effective components of the medicinal materials are extracted by decoction, which has the disadvantages of long extraction time, high extraction temperature, high energy consumption, easy loss of heat-sensitive components, low recovery rate of active components, troublesome post-processing, etc., especially the obtained water-soluble extract Very little, the color of the clear paste is extremely light, which leads to problems such as unqualified properties of the finished product

Abstract

The invention discloses a preparation method of stranguria-treating and calculus-removing particles. The method employs the technology of integrated membrane filter pressing circulating extraction and separation to extract effective components of prescription medicinal materials, thus not only simplifying the technological process, greatly shortening the production period, saving the energy consumption and benefiting for environmental protection and waste residue utilization, but also substantially improving the recovery rate of the effective components and solving the quality problems like unqualified finished product properties caused by few water-soluble extract and undertint of a clear paste. A membrane filter pressing method is employed to replace the traditional method of alcohol precipitation standing separation for the water extracted and condensed clear paste of the prescription medicinal materials. After adding alcohol and stirring, the paste, with no need for standing, can be pumped into a membrane filter press instantly for filter pressing and squeezing, so that the alcohol precipitation treatment can be finished rapidly and efficiently. Not only is the time consumption greatly reduced, but the recovery rate of an alcohol-containing liquid medicine is also obviously enhanced.

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 State Food and Drug Administration Standard (Trial) WS-11044 (ZD-1044)-2002 records: Shilintong granule has the effect of clearing away dampness and heat, diuresis and stone removal, and is used for urinary calculi, pyelonephritis, and gallbladder caused by dampness and heat in the lower jiao. inflammation. Its prescription is 10000g of Desmodium sativa, 533g of soluble starch, made into 1000g. Its preparation method is to decoct Desmodium sativa with water twice, each time for 1 hour, combine the decoction, filter, and concentrate the filtrate under reduced pressure to a clear paste with a relative density of 1.13-1.20 (70°C), let it cool, and add ethanol Make the alcohol content reach 65%, stir well, let it stand for 24 hours, filter, concentrate the filtrate to a clear paste with a rela...
