Embodiment 1
[0040] Embodiment 1: the preparation of ginseng extract
[0041] 1) Take ginseng medicinal materials and add water to extract, and the extract is concentrated into a ginseng extract containing 25% solids;
[0042] 2) After the ginseng extract is degreased, it is purified by D-type macroporous resin, washed with water: 95% ethanol according to the gradient elution method to remove the ginseng triol glycosides components and most of the ginseng diol glycosides components outside Rd, and then separately with 70 % ethanol elutes the saponins mainly composed of ginsenoside Rd, collects the eluate and decolorizes it, recovers the solvent, concentrates it, and dries it under reduced pressure to make a dry product;
[0043] 3) The dry product is dissolved in 95.0% ethanol, and the insoluble matter is filtered out with a 50 μm filter membrane. After being absorbed by a monodisperse polymeric silica gel chromatography column, it is eluted and purified with water: the concentration is 95...
Embodiment 2
[0045] Embodiment 2: the preparation of ginseng extract
[0046] 1) Take ginseng medicinal materials and add ethanol with a concentration of 25% for extraction, recover ethanol from the extract to obtain a ginseng extract containing 20% solids;
[0047] 2) After the ginseng extract is degreased, it is purified by D-type macroporous resin, washed with water: 95% ethanol according to the gradient elution method to remove the ginseng triol glycosides components and most of the ginseng diol glycosides components other than Rd, and then separately with 95 % ethanol elutes the saponins mainly composed of ginsenoside Rd, collects the eluate and decolorizes it, recovers the solvent, concentrates it, and dries it under reduced pressure to make a dry product;
[0048] 3) The dry product is dissolved in 96% ethanol, and the insoluble matter is filtered out with a 45 μm filter membrane, and after being absorbed by a monodisperse polymeric silica gel chromatography column, it is eluted a...
Embodiment 3
[0050] Embodiment 3: the preparation of ginseng extract
[0051] 1) Take the ginseng medicinal material and extract it with 96% ethanol, recover the ethanol from the extract to obtain a ginseng extract containing 5% solids;
[0052] 2) After the ginseng extract is degreased, it is purified by D-type macroporous resin, washed with water: 95% ethanol according to the gradient elution method to remove the ginseng triol glycosides components and most of the ginseng diol glycosides components other than Rd, and then separately with 95 % ethanol solution to elute the saponins mainly composed of ginsenoside Rd, collect the eluent and decolorize it, recover the solvent, concentrate, dry under reduced pressure, and make a dry product;
[0053] 3) The dry product is dissolved in 98.0% ethanol, and the insoluble matter is filtered out with a 1 μm filter membrane, and then absorbed by a monodisperse polymeric silica gel chromatography column, and purified by gradient elution with water: t...
