Example Embodiment

[0012] Preparation of the traditional Chinese medicine extract of the present invention-paeoniflorin:

[0013] 5000g peony and licorice add 12 times the amount of water, decoct and extract 3 times, 1 hour each time, filter, combine the extracts, pass through a macroporous adsorption resin column, first wash with appropriate amount of water, and then eluted with 70% ethanol , Collect the ethanol eluate, recover the ethanol under reduced pressure, concentrate into an extract, and dry under reduced pressure to obtain 294 g of paeoniflorin, with a yield of 5.9%. After content determination, the total content of paeoniflorin, glycyrrhizic acid and total flavonoid glycosides is 52.9%, of which paeoniflorin total glycosides 29.4%, glycyrrhizic acid 13.7%, and total flavonoid glycosides 9.8%.

[0014] Method of content determination:

[0015] The total glucosides of paeoniflora were determined according to high performance liquid chromatography (Chinese Pharmacopoeia 2000 Edition One Appe...

[0124] Example one

[0125] Preparation of Chinese medicine extract:

[0126] 1000g peony and licorice add 10 times the amount of water, decoct and extract 3 times, 1 hour each time, filter, combine the extracts, pass through a macroporous adsorption resin column, first wash with an appropriate amount of water, and then eluted with 60% ethanol , Collect the ethanol eluate, recover the ethanol under reduced pressure, concentrate into an extract, and dry under reduced pressure to obtain 64.2 g of paeoniflorin, with a yield of 6.42%. It was determined that the total content of paeoniflorin, glycyrrhizic acid and total flavonoid glycosides was 54.1%, of which total paeoniflorin glycosides was 28.6%, glycyrrhizic acid 16.1% and total flavonoid glycosides were 9.4%. Add 17.5g of medicinal starch, mix well, and pack 0.28g / capsules. The usage and dosage are 2 capsules each time, three times a day.

[0127] Example two

[0128] 1000g peony and licorice add 15 times the amount of water, decoct and extract 2 times, 2 hours each time, filter, combine the extracts, pass through a macroporous adsorption resin column, first wash with appropriate amount of water, and then eluted with 75% ethanol , Collect the ethanol eluate, recover the ethanol under reduced pressure, concentrate into an extract, and dry under reduced pressure to obtain 61.8 g of paeoniflorin, with a yield of 6.18%. It was determined that the total amount of paeoniflorin, glycyrrhizic acid and total flavonoid glycosides was 56.6%, of which, the total amount of paeoniflorin glycosides was 31.2%, glycyrrhizic acid 14.8%, and total flavonoid glycosides 10.6%. Add 21.5g of medicinal starch and mix well to make a tablet 0.3g / tablet. The usage and dosage are 2 tablets each time, three times a day.

Abstract

A Chinese medicine is prepared from peony root and liquorice root through decocting, filtering, collecting the filtrate, adsorbing by macroreticular adsorptive resin, eluting with alcohol, collecting the eluting liquid, recovering alcohol, concentrating and drying. It can be used to treat chronic viral hepatitis B. Its advantage is high curative effect.

Description

technical field [0001] The invention relates to a traditional Chinese medicine extract, especially the extract of peony and licorice, its preparation method and its medical application. technical background [0002] Chronic hepatitis B is a liver lesion caused by long-term infection with hepatitis B virus that cannot be cleared. It is one of the common refractory diseases in the world today. The incidence rate of chronic hepatitis B is very high. According to the report of Center for Disease Control in Atlanta, USA, there are about 270 million HBsAg carriers in the world. At least 600 million people in my country have been infected with hepatitis B virus, and about 120 million people are HBsAg carriers, 1 / 4 of which eventually develop into chronic hepatitis B virus. Chronic viral hepatitis B has a complex transmission route, a long course of disease, easy recurrence and chronicity, and is closely related to liver cirrhosis and liver cancer. It is ver...
