Abstract

The invention provides a preparation method for a Sanhuang tablet. The Sanhuang tablet is prepared from the bulk drugs consisting of 300 g of rhubarb root and rhizome, 5 g of berberine hydrochloride and 80 g of baical skullcap root extract through supercritical extraction, so the content of Sanhuang tablet is greatly increased, and the dose of the Sanhuang tablet is reduced. The invention further provides application of the Sanhuang tablet in preparation of drugs used for inhibiting cell proliferation of human large cell carcinoma NCI-H460.

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 Sanhuang tablets. Background technique [0002] Sanhuang tablets are recorded in the Pharmacopoeia. The prescription is 300g of rhubarb, 5g of berberine hydrochloride, 21g of baicalin extract (equivalent to 15g of baicalin). 1 hour for the second time, 40 minutes for the third time, combine the decoction, filter, add hydrochloric acid to the filtrate to adjust the pH value to 1-2, let it stand for 1 hour, take the precipitate, wash with water to make the pH value to 5-7, and dry , crushed into fine powder, assayed for content, and set aside. Take 150g rhubarb, crush it into fine powder, and sieve; the remaining rhubarb is crushed into coarse powder, add 30% ethanol to reflux and extract three times, filter, combine the filtrate, recover ethanol and concentrate under reduced pressure to a thick paste, add r...
