preparation example Construction

[0017] The preparation method of the Chinese medicine for treating diabetes of the present invention comprises the following steps:

[0018] 1) The materials are weighed according to the mass percentage of 20-50% of coptis, 20-50% of red ginseng, 10-20% of Alisma, and 10-20% of kudzu root.

[0019] 2) Take Coptis chinensis, add medicinal ethanol with a volume percentage of 60-80%, and reflux for 1-3 times. The amount of ethanol used each time is 7-9 times the amount of medicinal materials, and each time is 0.5-1.5 hours. Collect ethanol reflux, filter, and recover ethanol under reduced pressure. Add hydrochloric acid to the concentrated solution to adjust the pH value to 2.0-3.0, let it stand overnight, and filter it with suction. Dissolve the precipitate in heated water, filter, concentrate the filtrate, cool and stand overnight, filter with suction, and dry the precipitate at a low temperature of 50-60°C. Obtain the Coptidis Rhizoma extract, set aside.

[0020] 3) Take re...

Embodiment 1

[0025] Take 400 g of Coptidis rhizome, add 70% medicinal ethanol to reflux three times, each time the amount of ethanol is 8 times the amount of the medicinal material, and each time is 1 hour. Collect ethanol reflux, filter, and recover ethanol under reduced pressure. Add hydrochloric acid to the concentrated solution to adjust the pH value to 2.0-3.0, let it stand overnight, and filter it with suction. Dissolve the precipitate in heated water, filter, concentrate the filtrate, cool and stand overnight, filter with suction, dry the precipitate at low temperature (50-60° C.) to obtain the extract of Coptis rhizome. Take 400g of red ginseng, 200g of Alisma, and 200g of kudzu root, add water to extract twice, each time for one hour, each time 10 times the amount, combine the two water extracts, filter, concentrate to a relative density of 1.15, add ethanol until the alcohol content reaches 70%, let it stand overnight, filter, the filtrate is decompressed to recover ethanol, and...

Embodiment 2

[0027] Take 240g of Coptidis Rhizoma, add 70% medicinal ethanol to reflux three times, each time the amount of ethanol is 8 times the amount of medicinal materials, and each time is 1 hour. Collect ethanol reflux, filter, and recover ethanol under reduced pressure. Add hydrochloric acid to the concentrated solution to adjust the pH value to 2.0-3.0, let it stand overnight, and filter it with suction. Dissolve the precipitate in heated water, filter, concentrate the filtrate, cool and stand overnight, filter with suction, dry the precipitate at low temperature (50-60° C.) to obtain the extract of Coptis rhizome. Take 600g of red ginseng, 120g of Alisma, and 240g of kudzu root, add water to extract twice, each time for one hour, each time 10 times the amount, combine the two water extracts, filter, concentrate to a relative density of 1.15, add ethanol until the alcohol content reaches 70%, let it stand overnight, filter, the filtrate is decompressed to recover ethanol, and the...

Abstract

The invention discloses a traditional Chinese medicine for treating diabetes and a preparation method thereof. The traditional Chinese medicine is prepared from the following materials in weight percentage: 20 to 50 percent of rhizoma coptidis, 20 to 50 percent of red ginseng, 10 to 20 percent of Alisma orientale and 10 to 20 percent of radix puerariae. The rhizoma coptidis is refluxed by alcohol; the red ginseng, the Alisma orientale and the radix puerariae are extracted by adding water; and extracts are dried and tabletted to obtain the traditional Chinese medicine. The traditional Chinese medicine has functions of treating the diabetes and complicating diseases of the diabetes by reducing blood sugar and blood fat, reducing cataract, improving the weak constitution of diabetes patients and so on.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine pharmacy, in particular to a traditional Chinese medicine for treating diabetes and a preparation method thereof. Background technique [0002] Diabetes is a kind of common disease, frequently-occurring disease. Diabetes has a long course and there is currently no cure. The number of deaths caused by diabetes complications ranks third after cardiovascular and cerebrovascular diseases and tumors in developed countries, which has attracted great attention from all over the world, and researches on the pathogenesis and drug prevention and treatment of diabetes have been carried out one after another. [0003] At present, the hypoglycemic market in my country is dominated by western medicine, accounting for about 73.68% of the entire market share; supplemented by Chinese patent medicine, accounting for about 24.7%. Chemical hypoglycemic drugs account for the absolute dominant share of hyp...
