Embodiment 1
[0058] (1) Combined extraction of ginseng and schisandra, the extraction steps are as follows:
[0059] Add water to the medicinal materials, adjust the pH to 9, decoct three times, 30 minutes each time, and combine the extracts;
[0060] Successively use 75% ethanol and 85% ethanol to refrigerate and precipitate, filter, recover ethanol under reduced pressure until the relative density is 1.1-1.20, and the obtained product is a composite extract.
[0061] (2) Ophiopogon japonicus is extracted separately, and the extraction steps are as follows:
[0062] 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 ab...
Embodiment 2
[0065] (1) Combined extraction of ginseng and schisandra, the extraction steps are as follows:
[0066] Add water to the medicinal materials, adjust the pH to 14, decoct three times, 1 hour each time, and combine the extracts;
[0067] Successively use 75% ethanol and 85% ethanol to refrigerate and precipitate, filter, recover ethanol under reduced pressure until the relative density is 1.1-1.20, and the obtained product is a composite extract.
[0068] (2) Ophiopogon japonicus is extracted separately, and the extraction steps are as follows:
[0069] Take medicinal materials and use 95% 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 0.2g of crude drug per ml, add ethanol to sink to the concentration 80%, stand still, filter, precipitate with appropriate amount of absolute ethanol, wash with acetone in sequence, and...
Embodiment 3
[0072] (1) Combined extraction of ginseng and schisandra, the extraction steps are as follows:
[0073] Add 30% ethanol 4 times the amount of the crude drug, adjust the pH to 9, and extract under reflux for 1 hour each time, and the product obtained is a composite extract.
[0074] (2) Ginseng is extracted separately, and the extraction steps are as follows:
[0075] Take Ophiopogon japonicus medicinal material and percolate with 90% ethanol, remove alcohol after percolation, extract with water 3 times in the usual way, each time for 40 minutes, filter while hot, add 0.2% activated carbon to the filtrate, stir evenly, let stand overnight; filtrate decarbonized extraction Concentrate the liquid under reduced pressure to 1 / 10 of the original volume, add 95% ethanol for ethanol analysis, and make the alcohol content reach 80%, let stand to precipitate and precipitate, and the ethanol precipitate is drained, washed with absolute ethanol and acetone successively, and dried at 60°C ...
