Example Embodiment
[0023] Example 1:
[0024] Weigh 50g of rhubarb coarse powder, extract twice by flash extraction, add 9 times the amount of 50% ethanol for the first time and 6 times the amount of 50% ethanol for the second time. The extract is filtered with four layers of gauze. The total anthraquinone content of rhubarb in the extract was determined under the above chromatographic conditions and the extraction rate and extract rate were calculated.
Example Embodiment
[0025] Example 2:
[0026] Weigh 50g of rhubarb coarse powder, extract twice by flash extraction, add 9 times the amount of 70% ethanol for the first time, and 6 times the amount of 70% ethanol for the second time. The extract is filtered with four layers of gauze. The total anthraquinone content of rhubarb in the extract was determined under the above chromatographic conditions and the extraction rate and extract rate were calculated.
