Embodiment 1
[0020] Extraction of components:
[0021] 1000 g of Panax notoginseng medicinal materials are crushed into coarse powder, 2.5 times the amount of 90% ethanol is added, and the mixture is heated to reflux for extraction, and concentrated under reduced pressure until it has no alcohol taste. Dilute with water to 0.25g (crude medicine) / ml, stand for 24 hours, and filter. The filtrate was passed through a macroporous adsorption resin column, followed by gradient elution with 20%, 40%, 60%, 80% and 90% (volume ratio) ethanol, and collected in 500 ml portions. The eluent was analyzed by silica gel H thin-layer chromatography, the developing solvent was "n-butanol-ethyl acetate-water" 5:0.5:4 (upper layer), and the color was developed by a 10% (volume ratio) sulfuric acid ethanol solution. Combine the same components of the chromatographic spots and recover the solvent under reduced pressure. Then apply the chromatography silica gel column, and eluted with the solvents of "chloroform-...
Embodiment 2
[0031] The extraction of the components is the same as in Example 1.
[0032] Weigh the following components (same as above): ginsenoside Rg1 30g, ginsenoside Rb1 28.5g, ginsenoside Re3.0g, ginsenoside Rd 7.5g and notoginsenoside R1 7.8g.
[0033] The preparation method is as follows: mix the above-mentioned components, dissolve in an appropriate amount with water for injection, add needles to decolorize with activated carbon, filter, add water for injection to the total amount, adjust pH to 6.7, filter, freeze-dry, and get ready.
Embodiment 3
[0035] Weigh the following components: ginsenoside Rg1 45g, ginsenoside Rb1 29g, and ginsenoside Re 2.5g.
[0036] The preparation method is as follows: mix the above-mentioned components, dissolve in proper amount with water for injection, add needle to decolor with activated carbon, filter, add water for injection to the total amount, adjust pH to 6.0, filter, freeze-dry, and get ready.
