[0056] The preparation of embodiment 1 notoginseng triol group saponins
[0057] Panax notoginseng, crushed into granules, passed through a 20-mesh sieve, soaked in 6 times of 70% ethanol for 8 hours, installed in a percolation barrel for percolation, collected 30 times the amount of 70% ethanol percolation liquid, and the percolation flow rate was 1BV / h, and the percolation liquid Concentrate under reduced pressure below 70°C to 1.5 times the medicinal material, centrifuge, and concentrate the supernatant to dryness under reduced pressure. The dried sample was passed through a neutral alumina column, eluted with a certain ratio of ethanol and water (volume ratio 1:5), and the end point of elution was judged by TLC. The organic solvent is recovered under vacuum and decompression below 70°C; the concentrated solution is diluted with water to 5 times the volume of the medicinal material, and the sample loading flow rate on the diluted solution is 1BV / h, 7.5 times Column volume,...

[0071] Radix Notoginseng, crushed into granules (through a 20-mesh sieve), soaked in 3 times of 70% ethanol for 8 hours, installed in a percolation barrel for percolation, collected 20 times the amount of 70% ethanol percolation liquid, the percolation flow rate is 1BV / h, and percolated The solution was concentrated under reduced pressure below 70°C to 1.5 times that of the medicinal material, centrifuged, and the supernatant was concentrated to dryness under reduced pressure. Dry the sample through a neutral alumina column, elute with acetone and water in a certain ratio (volume ratio 1:1), and judge the elution end point by TLC. The organic solvent is recovered under vacuum and decompression below 70°C; the concentrated solution is diluted with water to twice the volume of the medicinal material, and the sample flow rate of the macroporous anion exchange resin ((resin and medicinal material 0.5: 1g / g) on the diluted solution is 0.5BV / h, 5 Double the column volume, flow rat...
Embodiment 4
[0073] Radix Notoginseng, crushed into granules (through a 20-mesh sieve), soaked in 10 times of 70% ethanol for 8 hours, installed in a percolation barrel for percolation, collected 40 times the amount of 70% ethanol percolation liquid, the percolation flow rate is 1BV / h, and percolated The solution was concentrated under reduced pressure below 70°C to 1.5 times that of the medicinal material, centrifuged, and the supernatant was concentrated to dryness under reduced pressure. Dry the sample through a neutral alumina column, elute with a certain ratio of organic solvent and water (volume ratio 1:10), and judge the elution end point by TLC. The organic solvent is recovered under vacuum and reduced pressure below 70°C; the concentrated solution is diluted with water to 2 to 10 times the volume of the medicinal material, and the sample loading flow rate on the diluent is 1.5BV / h on the macroporous anion exchange resin ((resin and medicinal material 1:1g / g) , 10 times the column ...
