Embodiment 1

[0021] Example 1 Preparation of Salvia Miltiorrhiza Extract

[0022] Take Salvia miltiorrhiza, crush it into coarse powder, soak it for 1 hour, add 8 times the amount of water to decoct three times, each time for 1 hour, combine the decoction, filter, and concentrate the filtrate under reduced pressure below 60°C to a clear paste with a relative density of 1.30~1.35 , let it cool, add 4 times the amount of 95% ethanol to make the alcohol content reach 50%, stir evenly, let it stand overnight, precipitate, filter, recover ethanol from the filtrate under reduced pressure, and dry the concentrated solution in a crawler-type vacuum oven to obtain final product.

Embodiment 2

[0023] Example 2 The detection of the salvia miltiorrhiza extract described in Example 1

[0024] Properties: yellow powder, fragrant gas, bitter taste.

[0025] Identification: Take 0.2g of this product powder, add 2ml of 75% methanol, ultrasonically treat for 20 minutes, filter, and the filtrate is used as the test solution. Another reference substance of salvianolic acid B and danshensu sodium was added with 75% methanol to make a solution containing 2mg per 1ml, as the reference substance solution. According to the test of thin-layer chromatography (Appendix VI B), draw 3 μl of each of the above two solutions, and spot them on the same silica gel HSG thin-layer plate respectively, using -chloroform-acetone-formic acid (10:4:1.6) as the developing solvent , unfolded, taken out, dried in the air, sprayed with 5% FeCl3 ethanol solution, and dried at 105°C. In the chromatogram of the test product, there are spots of the same color at the position corresponding to the chromat...

Embodiment 3

[0048] Example 3 Preparation of Salvia Miltiorrhiza Extract

[0049] Take Salvia miltiorrhiza, crush it into coarse powder, soak it for 1 hour, add 8 times the amount of water and decoct three times, each time for 1 hour, combine the decoction, filter, and the filtrate is concentrated by rotary evaporation to a clear paste with a relative density of 1.30~1.35, and let it cool. Add 4 times the amount of 95% ethanol to make the alcohol content reach 50%, stir evenly, let stand overnight, precipitate, filter, recover ethanol from the filtrate under reduced pressure, and spray-dry the concentrated solution to obtain the final product.

Abstract

A red sage root extract containing danshinolic acid (not less than 5.0%) and danshensu (not less than 2.0%) is prepared through pulverizing red sage root, decocting, collecting liquid extract, filtering, concentrating, cooling, adding alcohol, recovering alcohol, and drying. A medicine containing it is also disclosed.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine salvia miltiorrhiza, in particular to the technical field of salvia miltiorrhiza extract, preparation and preparation method thereof. Background technique [0002] Chinese medicine extract is an emerging field differentiated from the Chinese medicine industry, and it is an in-depth processing of Chinese medicinal materials. The essence of traditional Chinese medicine extracts is traditional Chinese medicine raw materials, which have the advantages and characteristics of less investment, high technical content, high added value of products, and wide international market. After years of development, Chinese medicine extracts have reached a certain industrial scale, and the export ratio has surpassed that of traditional Chinese medicine, showing an upward trend. At present, there are no national standards or industry standards for the vast majorit...
