Embodiment 1
[0058] Combined extraction of ginseng and schisandra, the extraction steps are as follows:
[0059] Add water to the medicinal material, adjust the pH to 9, decoct three times, 30 minutes each time, combine the extracts, purify the extracts with macroporous adsorption D101 resin, concentrate the eluent and filter, and the obtained product is a combined extract.
[0060] Ophiopogon japonicus is extracted separately, and the extraction steps are as follows:
[0061] Take the medicinal materials and use 95% ethanol to percolate and degrease, evaporate the residue in the column to dry the ethanol, add 8 times the amount of hydrothermal reflux to extract twice, each time for 30 minutes, concentrate the water extract to contain 0.2g of crude drug per ml, add ethanol to sink to The concentration is 80%, let it stand, filter, the precipitate is washed successively with appropriate amount of absolute ethanol and acetone, and vacuum-dried at 50°C to obtain the crude polysaccharide of Op...
Embodiment 2
[0064] Combined extraction of ginseng and schisandra, the extraction steps are as follows:
[0065] Add water to the medicinal material, adjust the pH to 14, decoct three times for 1 hour each time, and combine the extracts; the extracts are purified by macroporous adsorption D101 resin, the eluent is concentrated and filtered, and the product obtained is a combined extract.
[0066] Ophiopogon japonicus is extracted separately, and the extraction steps are as follows:
[0067] Take medicinal materials and use 60% ethanol to percolate and degrease, evaporate the residue in the column to dry ethanol, add 8 times the amount of hydrothermal reflux to extract twice, each time for 30 minutes, concentrate the water extract to contain 0.2g of crude drug per ml, add ethanol to sink to The concentration is 80%, let it stand, filter, the precipitate is washed successively with appropriate amount of absolute ethanol and acetone, and vacuum-dried at 50°C to obtain the crude polysaccharide...
