Embodiment 1
[0135] Example 1 Preparation of Ginseng Polysaccharide
[0136] Ginseng polysaccharide preparation process:
[0137] Take ginseng, chop it, extract with 75% ethanol, reflux for 4 hours, filter, dry the medicine residue, add water and cook five times, combine the decoction, add 0.3% activated carbon, stir for 30 minutes, let stand overnight, filter Pass the filtrate through a resin column, collect the effluent, concentrate under reduced pressure, add ethanol to make the alcohol content reach 95%, refrigerate, filter, take the precipitate and wash with acetone, drain the acetone, take out the precipitate and dry at 60~80℃, and crush it. Got.
[0138] Ginseng polysaccharide identification test
[0139] (1) Take about 0.2g of this product, add 5ml of water to dissolve it, add 5 drops of alkaline copper tartrate test solution, heat it to produce a red precipitate, cool, filter, take the filtrate and add 1 drop of hydrochloric acid to make it acidic, and heat it in a water bath for 10 ...
Embodiment 2
[0148] Example 2 Preparation of ginseng total saponins
[0149] Preparation process of total ginseng saponins:
[0150] Take the ginseng medicinal materials, crush them into fine particles, extract twice with ethanol reflux, 3 hours each time, add 10 times the amount of alcohol each time, combine the extracts, refrigerate, filter, and recover the ethanol from the filtrate and concentrate it to a thick paste. Add water to an appropriate amount ( Make each 1ml equivalent to 1g of the original medicinal material), stir well, refrigerate, and filter. The filtrate is added to the processed macroporous resin column, first eluted with 2V~3V column volume of water, discarded the washing liquid, and then Elute with 3 times the column volume of 80% ethanol, collect the eluate, recover the ethanol and concentrate it under reduced pressure to a thick paste with a relative density of 1.30 to 1.35, and vacuum dry to obtain.

[0152] Take 0.5...
Embodiment 3
[0165] Example 3 Preparation of Astragalus Polysaccharide
[0166] Astragalus polysaccharide preparation process:
[0167] Take astragalus medicinal materials, add 7 times the amount of 70% ethanol to extract twice, 2 hours each time, discard the extract, take the medicinal residue and add water to extract twice, combine the extracts and concentrate until the ratio of the volume of the extract to the crude medicinal material is 1.05: 1. Add ethanol to precipitate to make the alcohol content reach 70%, filter to obtain the precipitate, wash the precipitate with 70% ethanol, then dissolve it with an appropriate amount of water, filter, the filtrate is over the macroporous resin, eluted with water, collect the washing liquid, and wash the liquid Concentrate to a ratio of 1:2.5 between the volume of the medicinal solution and the medicinal materials. Add ethanol to make the alcohol content reach 70% to obtain a precipitate. The precipitate is washed and dehydrated with 95% ethanol an...
