Abstract

The invention discloses a preparation method of radix bupleuri and Radix Scutellariae granules. The method comprises the following steps: 1, extraction of effective components of radix bupleuri, and volatile oil embedding; 2, extraction of effective components of Radix Scutellariae; 3, treatment of the effective components of Radix Scutellariae; 4, mixing and granulation; and 5, granule packaging. The preparation method of the radix bupleuri and Radix Scutellariae granules is systemically researched and comprehensively improved from the extraction and purification of the effective components to the mixing of the effective components of medicines and to the granulation of a preparation. The method has the advantages of high operability, quality guaranteeing, improvement of the content of radix bupleuri volatile oil in the radix bupleuri and Radix Scutellariae granules, and enhancement of the curative effect of the radix bupleuri and Radix Scutellariae granules to a certain degree.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine granules, and in particular relates to a preparation method of chaihuang granules. Background technique [0002] Chaihuang granule comes from the tenth volume of traditional Chinese medicine preparations issued by the Ministry. The State Food and Drug Administration issued a revised standard in 2008, the standard number: WS3-B-2009-95-2008. [Prescription] Bupleurum 1250g, Scutellaria baicalensis extract 90g; [Preparation method] For the above two flavors, add Bupleurum to decoct twice for 2 hours each time, combine the decoctions, filter, and concentrate the filtrate to a relative density of 1.10-1.20 To clean the ointment, add ethanol under stirring until the alcohol content is 60%, let it stand for more than 12 hours, filter, recover the ethanol from the filtrate, and concentrate to an appropriate amount; take the extract of Scutellaria baicalensis, mix it with the above-men...
