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.
