Abstract

The invention provides a preparation method of a middle calming tablet. The middle calming tablet is prepared from 180g of cassia twig, 180g of vinegar-treated corydalis tuber, 180g of calcined oyster, 120g of common fennel, 120g of amomum fruit, 60g of Chinese ginger and 120g of liquoric root serving as bulk pharmaceuticals. The middle calming tablet is prepared through ultrafine extraction and microwave extraction, so that the convent of tetrahydropalmatine is increased greatly. The invention further provides an application of the middle calming tablet to preparation of a medicament for inhibiting cell proliferation of rat breast cancer cells SHZ-88.

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 Anzhong tablets. Background technique [0002] Anzhong Tablets is recorded in the standard WS3-B-0929-91 of the Ministry of Health. It is made from 180g of cassia twig, 180g of vinegar-made corydalis, 180g of calcined oyster, 120g of fennel, 120g of amomum, 60g of galangal, and 120g of licorice as raw materials. It can warm the middle and dispel cold, regulate qi and relieve pain, harmonize the stomach and stop vomiting. For epigastric pain, chronic gastritis, hyperacidity, gastric and duodenal ulcer. [0003] In the prior art, there is no report on the use of supercritical and microwave technology in the extraction and preparation of Anzhong Tablets. However, the method of powdering and decocting in water is rough and backward, and there are many impurities, which leads to excessive dosage for patients an...
