Method for extracting saponins of traditional Chinese medicine
A technology of saponins and traditional Chinese medicine, which is applied to medical preparations containing active ingredients, plant/algae/fungus/moss ingredients, pharmaceutical formulas, etc. It can solve the problems of inconvenient industrial production, large loss of active ingredients, and high polarity. Achieve the effects of easy industrialized large-scale production, high content of saponins, and high extraction and separation efficiency

Embodiment 1
[0015] Take Bupleuri herb, crush it, add water to boil and extract three times and control the pH, the first time is 6 times the amount of water and 0.7% of the amount of Na2CO3, the second time is 4 times the amount of water and 0.3% of the amount of Na2CO3 , 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, the medicinal liquid is concentrated to 2 times the volume of the medicinal material, and ethanol is added to make the alcoholic The amount reaches 70%, let it stand for 24 hours, filter, the filtrate decompresses and recovers ethanol until it has no alcohol smell, dissolves it in water, and filters; the macroporous weakly basic anion D382 exchange column (Nankai University Chemical Plant) that has been treated on the filtrate ), rinsed with 2% NaOH solution of 2 times the volume of the resi...
Embodiment 2
[0017] Take the residue after extracting volatile oil from Bupleuri, add 50% ethanol to reflux extraction three times and control the pH, the first time is 5 times the amount of 50% ethanol and 1% Na2CO3 of the amount of the medicinal material, and the second time is 4 times the amount of the medicinal material 50% ethanol and 0.5% medicinal Na2CO3, the third time is 4 times the amount of medicinal materials and 50% ethanol; side countercurrent circulation reflux extraction, after the reflux starts, keep it for 1.5, 1, 1 hour respectively; filter the medicinal liquid and combine the filtrate , after the filtrate was concentrated under reduced pressure at 70°C to no alcohol smell, the concentrated solution was diluted with water to a ratio of medicinal material to liquid of 1:1.5, filtered, and the filtrate was treated with a macroporous strong basic anion D201 exchange column (Nankai University Chemical Industry Co., Ltd. factory), washed with 2% NaOH solution 2 times the volum...
Embodiment 3
[0019] Get Acanthopanax medicinal materials (roots, rhizomes, stems), pulverize, add 50% ethanol to reflux and extract three times and control the pH, the first time is 5 times the Na2CO3 of 50% ethanol amount and 1% medicinal material amount, and the second time 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 amount of medicinal materials; side countercurrent circulation reflux extraction, after the reflux starts, keep it for 1.5, 1, and 1 hour respectively; Filter the medicinal liquid and combine the filtrates, concentrate the filtrate under reduced pressure at 70°C until there is no alcohol smell, dilute the concentrated liquid with water until the ratio of medicinal materials to liquid is 1:1.5, filter, and the treated macroporous strong basic anion D201 on the filtrate Exchange column (Nankai University Chemical Plant), rinse with 2% NaOH solution of 2 times the volume of the...
