Embodiment 1
[0028] Take 500g of Shayuanzi coarse powder, add petroleum ether and reflux twice, each time for 2h, add 4L of petroleum ether each time, combine the extracts to recover petroleum ether under reduced pressure, add 50% ethanol to the dregs, and heat reflux for 3 times, each time reflux Flow for 2 hours, the amount of solvent is 5L each time, combine the extracts, concentrate under reduced pressure, add water to stir and dilute, add to the treated 1kgHPD100 column, wash with water until the collected solution is colorless, and then elute with 60% ethanol until it is colorless Or very shallow, combined, concentrated and dried to obtain the extract. Among them, sarcoside is 14.6%, and the total flavonoid content is 65.0%.
Embodiment 2
[0030] Take 500g of Shayuanzi coarse powder, add petroleum ether for ultrasonication 2 times, 2 hours each time, add 4L petroleum ether each time, combine the extracts to recover petroleum ether under reduced pressure, add 60% ethanol to the dregs and heat reflux twice, reflux 2 hours each time , the amount of solvent is 4L each time, the extracts are combined, concentrated under reduced pressure, stirred and diluted with water, added to the treated 1kgHPD100 column, washed with water until the collected solution is colorless, and then eluted with 70% ethanol until colorless or very shallow, combined, concentrated and dried to obtain the extract.
