Embodiment 1

[0019] Example 1 Preparation of Salvia Miltiorrhiza Extract

[0020] Take Salvia miltiorrhiza, crush it into coarse powder, soak for 30 minutes, add 10 times the amount of 70% ethanol to extract three times, each time for 1.5 hours, combine the decoction, filter, and concentrate the filtrate under reduced pressure below 60°C to a relative density of 1.30-1.35 (60°C) clear ointment, let it cool, and dry it in a crawler-type vacuum oven to get final product.

Embodiment 2

[0021] Example 2 The detection of the salvia miltiorrhiza extract described in Example 1

[0022] Properties: Brown powder, fragrant and bitter.

[0023] Identification: Take 0.2g of the powder of this product, add 2ml of ethyl acetate, ultrasonically treat for 20 minutes, filter, and the filtrate is used as the test solution. Another Tanshinone II A For the reference substance, add ethyl acetate to make a solution containing 1 mg per 1 ml, as the reference substance solution. According to the thin-layer chromatography (Appendix VIB) test, draw 5 μl of each of the above two solutions, and spot them on the same silica gel G thin-layer plate, use toluene-ethyl acetate (19:1) as the developing solvent, develop, take out, and dry Dry. In the chromatogram of the test product, there are spots of the same color at the position corresponding to the chromatogram of the reference product.
