[0007] Chinese patent, CN1247855A, disclosed in 2000 the method of extracting phenolic acids in salvia miltiorrhiza by resin method after water extraction, because the water extract has many impurities, resulting in low resin regeneration rate and low phenolic acid content in the extract
Chinese patent, CN1425659A, disclosed the method of extracting salvianolic acid B from salvianolic acid in 2003, which also has the above-mentioned defects, and salvianolic acid A, the most active active ingredient in salvianolic acid, has not been separated
Chinese patent, CN1513848A, disclosed in 2004 the method of extracting phenolic acids in salvia miltiorrhiza by means of water extraction, ultrafiltration, acidification, and extraction of acetates after acidification, and the extraction and extraction methods used in the literature It has been reported that the method of separation by reversed-phase column has been mentioned in the patent CN1425659A. This method does not explain how to specifically separate the components of phenolic acids in Salvia miltiorrhiza, and what is the content of the components of phenolic acids that are divided into also did not explain
[0010] At present, there are many reports on the pharmacological activity of the water-soluble components of Salvia miltiorrhiza, and there are many pharmacological studies on the main active components salvianolic acid A and salvianolic acid B, but there is no pharmacological study on the synergistic effect of the two, and the composition of traditional Chinese medicine is complex. , its efficacy is mostly the result of the synergistic effect of various chemical components. We have found through research that the contents of salvianolic acid A and salvianolic acid B in Danshen medicinal materials and different Danshen preparations and the ratio of the two are very different. The present invention finds that Salvia miltiorrhiza Phenolic acid A and salvianolic acid B have a synergistic effect on cardiovascular and cerebrovascular pharmacological effects, so the most reasonable composition of salvianolic acid A and salvianolic acid B based on pharmacodynamics is prepared

Embodiment 1

[0087] Embodiment 1: the preparation method of salvianolic acid A and salvianolic acid B and composition thereof (respectively extracting and mixing method)

[0088] The specific process steps are as follows

[0089] 1. Extraction: Take Danshen decoction pieces, add 10 times the amount of 20% ethanol, soak at room temperature for 3 hours, then heat to 80-100°C for reflux extraction for 1.5 hours, separate the first extract, add 8 times the amount of 50% ethanol, and heat Reflux extraction at 80-100°C for 1 hour, and separate the second extract. The two extracts were combined, and the solid impurities in the extract were removed by filtration.

[0090] 2. Precipitation: Concentrate the extract under reduced pressure to a relative density of 1.05 to 1.10. After cooling, add deionized water 8 times the amount of medicinal materials, refrigerate, let stand, take the supernatant, and concentrate under reduced pressure to obtain a concentrate.

[0091] 3. Separation and purificati...

Embodiment 2

[0101] Embodiment 2: the preparation method of salvianolic acid A and salvianolic acid B and composition thereof, (simultaneous extraction method)

[0102] Other parts of the method are the same as in Example 1, and the column chromatography separation and purification process is different, and the column chromatography separation and purification method is as follows:

[0103] The pre-treated AB-8 macroporous adsorption resin column on the concentrated solution, the ratio of the sample on the column to the amount of resin is 1:8 (W:W), first eluted with deionized water for 20 column bed volumes to remove impurities, and then Elute 20 column bed volumes with 20% ethanol aqueous solution to remove impurities, then elute salvianolic acid B and salvianolic acid A with about 70% ethanol aqueous solution, and monitor salvianolic acid B in the eluent with TLC during the elution process and the content changes of salvianolic acid A, combined with HPLC monitoring, until the two are co...

Embodiment 3

[0104] Embodiment 3: the selection of pH in the preparation technology of sodium salt derivative

[0105] Take 100 g of the salvianolic acid A and B raw materials obtained in the above-mentioned Example 1, dissolve them in 500 ml of water, add 0.01 to 0.5 N sodium bicarbonate solution to adjust the pH to 6, 7, 8, 9, 10, 12, and 14 respectively, and fully After stirring, centrifuge to remove insoluble matter, concentrate the solution under reduced pressure, add ethanol to the alcohol concentration of 80%, let it stand still, filter the precipitate, and dry under reduced pressure to obtain the sodium salt of salvianolic acid A plus B, calculate the weight, and measure the salvia miltiorrhiza The contents of phenolic acid A sodium salt and salvianolic acid B sodium salt are shown in Table 1.

[0106] pH

[0107] The data in Table 1 shows that the influence of pH in the preparation process of salvianolic acid A+B sodium salt derivatives is very important: pH10, the conte...
