preparation example 1
[0016] Preparation Example 1: Preparation of Ginseng Extract
[0017] Take 5 kg of ginseng, crush it, add 5 times the amount of water to soak, ultrasonically extract twice, combine the extracts, concentrate under reduced pressure to a relative density of 1.1, add ethanol solution to make the alcohol concentration reach 70%, stir well, and precipitate overnight; filter, filtrate Concentrate under reduced pressure to remove alcohol; the concentrated solution is loaded on the treated macroporous adsorption resin column, the ratio of sample volume to resin volume is 5:1, first eluted with 30% ethanol to remove impurities, and then eluted with 60% ethanol Until the concentration of saponins was significantly reduced, the 60% ethanol eluate was collected, concentrated under reduced pressure, and dried to obtain 320 g of ginseng extract with a yield of about 7%. The total saponin content of ginseng was 62%.

[0018] Preparation Example 2: Preparation of Ginseng Extract
[0019] Take 3 kg of ginseng, crush it, add 10 times the amount of water to soak, ultrasonically extract twice, combine the extracts, concentrate under reduced pressure to a relative density of 1.05, add ethanol solution to make the alcohol concentration reach 70%, stir well, and precipitate overnight; filter, filtrate Concentrate under reduced pressure to remove alcohol; the concentrated solution is loaded on the treated macroporous adsorption resin column, the ratio of sample volume to resin volume is 5:1, first eluted with 30% ethanol to remove impurities, and then eluted with 60% ethanol Until the concentration of saponin is significantly reduced, collect the 60% ethanol eluate, concentrate under reduced pressure until it has no alcohol smell, put the sample on the treated polyamide chromatography column, wash with water to remove non-absorbed impurities, and elute with 10% ethanol for 2 discarded, and then elut...
preparation example 3
[0020] Preparation Example 3: Preparation of Aconite Extract
[0021] Take 1000g of aconite medicinal material, add 8000ml of water, adjust the pH value to 12 with 1N sodium hydroxide solution, soak at room temperature for 24 hours, until there is no aconitine and hypoaconitine identified by TLC. The residue is percolated with dilute hydrochloric acid solution to extract alkaloids, and the alkaloid precipitation reaction is detected until the extraction is complete; the filtrate and percolation liquid are combined, and the pH value of the solution is adjusted to 2 with dilute hydrochloric acid; the sample is applied to the treated 732 strongly acidic cation exchange The resin was replaced with ammonia solution, and the organic solvent was eluted. The eluate was collected and concentrated under reduced pressure to obtain 3.1 g of total alkaloids of aconite, with a yield of about 0.3%. The content of total alkaloids determined by acid dye colorimetry was 58%.
