Embodiment 1
[0014] Take 10 kg of wild Cyan ginseng root, crush it, extract it three times with 80% ethanol, combine the extracts, concentrate and recover the solvent. The concentrated solution was diluted with water, extracted three times with petroleum ether, and the aqueous layer was extracted three times with chloroform, and the chloroform fractions were combined. Chloroform was recovered to obtain 230 g of light yellow powder, with a yield of 2.3%. The obtained light yellow powder is the total glycosides of Qingyangshen, taking caudatin as the reference substance, referring to the drug standard (WS 3 -B-2343-97) method, the measured total glycoside content is 62.5%.
[0015] Both Lieberman-Burchard and Keller-Killiani reactions were positive, indicating that the total glycosides were steroidal compounds containing 2-deoxysugars.
Embodiment 2
[0017] Take 10 kg of cultivated Cyan ginseng root, crush it, extract it three times with 75% ethanol, combine the extracts, concentrate and recover the solvent. The concentrated solution was diluted with water, extracted three times with petroleum ether, and the aqueous layer was extracted three times with chloroform, and the chloroform fractions were combined. Chloroform was recovered to obtain 310 g of light yellow powder, with a yield of 3.1%. The obtained light yellow powder is the total glycosides of Qingyangshen, taking caudatin as the reference substance, referring to the drug standard (WS 3 -B-2343-97) method, the measured total glycoside content is 65.5%.
Embodiment 3
[0019] Mix 100g of total glycosides of Qingyang ginseng, 60g of starch, and 5g of dextrin evenly, add 10% starch slurry to make soft material, granulate with 14-mesh nylon screen, ventilate and dry at 60-70°C, granulate with 16-mesh sieve, add hard 1.5 g of magnesium fatty acid and 5 g of sodium carboxymethyl starch were mixed, pressed into 1000 tablets, and coated to obtain the required tablets, each containing 100 mg of total glucosides of Qingyangshen.
