Embodiment 1
[0049] Example 1 Preparation of Dipsacus total aglycon and hedera saponin
[0050] Take 1 kg of Dipsacus medicinal material, and reflux extract with 8 times the amount of 75% ethanol for 3 times. For 3 hours each time, combine the extracts three times, add 30g of calcium oxide, stir, stand overnight, filter, adjust the pH of the filtrate to 6-7 with dilute hydrochloric acid, add 200g of activated carbon, stir, filter, and recover ethanol from the filtrate until it is free of alcohol Add water to 2000ml, pass through the treated macroporous resin column, first wash 3 times the column volume with 20% ethanol with a pH value of 12, then wash with water until neutral, finally elute with 70% ethanol, collect 70% The eluate was concentrated to dryness under reduced pressure; hydrolyzed with 12 times the amount of 2N hydrochloric acid and 40% ethanol for 3 hours. Filtrate, discard the hydrolyzate, wash the filter cake with deionized water until neutral; then heat to boiling with 95...
