Embodiment 1
[0015] Take notoginseng medicinal materials (roots, stems), crush them, add water to boil and extract three times and control the pH, the first time is 6 times the amount of medicinal materials and 0.7% Na2CO3, the second time is 4 times the amount of medicinal materials and 0.3% Na2CO3 % Na2CO3 of the amount of medicinal material, the third time is 4 times the amount of water of the medicinal material; side countercurrent circulation extraction, after boiling, keep for 1.5, 1, 1 hour respectively; the medicinal liquid is combined and cooled to room temperature, filtered, and the filtrate has treated macropores Type weakly basic anion D392 exchange column (Nankai University Chemical Plant), rinse with 2% NaOH solution of 2 times the volume of the resin bed, discard the rinse solution; then rinse with pure water 3 times, discard the water rinse solution; use 7 times the volume of the resin bed Elute with 70% ethanol by bed volume, collect the eluate, concentrate to a thick paste...
Embodiment 2
[0017] Take Panax notoginseng leaves, crush them, add water and ultrasonically extract four times and control the pH, the first time is 5 times the amount of water and 0.9% of the amount of NaHCO3, and the second time is 4 times the amount of water and 0.5% of the amount of herbs NaHCO3, the third and fourth times are 3 times the amount of water of the medicinal material; the medicinal liquid is combined and cooled to room temperature, filtered, and the macroporous weakly basic anion D380 exchange column (Nankai University Chemical Plant) that has been processed on the medicinal liquid filtrate ), rinsed with 2.5% NaOH solution of 1.5 times the volume of the resin bed, and discarded the rinse solution; rinsed with 4 times of pure water, discarded the water rinse solution; eluted with 65% ethanol of 8 times the volume of the resin bed, and collected the eluate , concentrated to a thick paste (relative density at 50° C. is 1.28 to 1.33), and dried with a dynamic belt drying devic...
Embodiment 3
[0019] Get the Radix Notoginseng medical material (root, stem), pulverize, add 50% ethanol backflow extraction three times and control pH, the Na2CO3 of 5 times of 50% ethanol amount and 1% medicinal material amount for the first time, the second time is medicinal material amount 4 times the amount of 50% ethanol and 0.5% Na2CO3 of the amount of medicinal materials, the third time is 4 times the amount of 50% ethanol of the medicinal materials; side countercurrent circulation reflux extraction, after the reflux starts, keep 1.5, 1, 1 hour respectively; liquid filtration And combine the filtrates, after the filtrates are concentrated under reduced pressure at 70°C until there is no alcohol smell, the concentrated solution is diluted with water to a ratio of medicinal material to liquid of 1:1.5, filtered, and the filtrate has been treated on the macroporous strong basic anion D201 exchange column ( Chemical Plant of Nankai University), rinse with 2% NaOH solution of 2 times the ...
