Problems solved by technology

[0003] In the prior art, there is no report on the use of supercritical and microwave technology in the extraction and preparation of Qingnao Jiangya Tablets. However, the method of powdering and decocting in water is rough and backward in process and has many impurities, which leads to excessive dosage for patients and unnecessary It is convenient to take, which has seriously affected the clinical application of this product

Abstract

The invention provides a preparation method of a brain-soothing hypertension pill. The brain-soothing hypertension pill is prepared by using 100g of baical skullcap roots, 60g of common selfheal fruit-spike, 60g of sophora flower bud, 60g of forged lodestone, 60g of twotooth achyranthes roots, 100g of Chinese angelica, 40g of rehmannia, 40g of danshen roots, 20g of sanguisuga, 60g of uncaria rhynchophylla, 100g of semen cassia, 20g of lumbricus and 40g of nacre as bulk drugs and adopting supercritical extraction and microwave-assisted extraction modes. By adopting the method, the content of baicalin is greatly improved; and the invention also provides application of the brain-soothing hypertension pill in preparation of drugs for inhibiting cell proliferation of rat adrenal pheochromocytoma PC-12.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine preparations, in particular to a preparation method and application of a Qingnao Jiangya tablet. Background technique [0002] Qingnao Jiangya tablet is recorded in the standard WS3-B-0424-90 of the Ministry of Health, consisting of 100g of Scutellaria baicalensis, 60g of Prunella vulgaris, 60g of Huai Mi, 60g of calcined magnet, 60g of Achyranthes bidentata, 100g of angelica, 40g of rehmannia glutinosa, 40g of salvia miltiorrhiza, 20g of leech, Uncaria 60g, cassia seed 100g, earthworm 20g, mother-of-pearl 40g are made as raw materials, which can clear the brain and lower blood pressure. For high blood pressure, dizziness, dizziness, insomnia, forgetfulness, and memory loss. [0003] In the prior art, there is no report on the use of supercritical and microwave technology in the extraction and preparation of Qingnao Jiangya Tablets. However, the method of powdering and decoct...
