Embodiment 1

[0041] Example 1 Preparation of effective fractions of flavonoids from hollyhock flower

[0042] Grind 100g of hollyhock flowers into coarse powder, extract with 15 times of 60% ethanol under reflux, and obtain the ambrette extract; after the amber extract is absorbed by activated carbon, filter it with an ultrafiltration membrane with a molecular weight cut-off of 3500, and collect the filtrate , the filtrate is filtered with an ultrafiltration membrane with a molecular weight cut-off of 500 to obtain a concentrated solution, and the concentrated solution is decompressed to recover ethanol at 50 ° C, and then treated with D101 macroporous resin. The treatment process of the macroporous resin is as follows: : The diameter-to-height ratio of the macroporous resin is 1:6, the concentration of the sample solution (aqueous solution) is 0.15g crude drug / ml, the volume of the sample solution is 7BV, and the sample is loaded at a flow rate of 2BV / h, with 6BV of pure water and 3BV of 5...

Embodiment 2

[0043] Example 2 Preparation of effective fractions of flavonoids from hollyhock flower

[0044] Grind 100g of hollyhock flowers into coarse powder, extract with 18 times of 70% ethanol under reflux, and obtain the ambrette extract; filter the amber extract with an ultrafiltration membrane with a molecular weight cut-off of 3500, collect the filtrate, Use an ultrafiltration membrane with a molecular weight cut-off of 1000 to filter out 70% of the liquid to obtain a concentrated solution. After the concentrated solution is decompressed at 60°C to recover ethanol, it is treated with D101 macroporous resin. The treatment process of the macroporous resin is: macroporous resin diameter The height ratio is 1:5, the concentration of the sample solution is 0.15g crude drug / ml, the volume of the sample solution is 6BV, the sample is loaded at a flow rate of 2BV / h, and impurities are removed with 6BV of pure water and 3BV of 5% ethanol at a flow rate of 2BV / h. Elute with 4BV 60% ethanol...

Embodiment 3

[0045] Example 3 Preparation of effective fractions of flavonoids from hollyhock flower

[0046] Grind 100g of hollyhock flowers into coarse powder, extract by percolation with 18 times of 60% ethanol to obtain the ambrette extract; The concentrated solution is obtained by filtering out 80% of the liquid with an ultrafiltration membrane with a molecular weight cut-off of 500. After the concentrated solution is decompressed at 60°C to recover ethanol, it is treated with D101 macroporous resin. The treatment process of the macroporous resin is: macroporous resin The diameter-to-height ratio is 1:8, the concentration of the sample solution is 0.15g crude drug / ml, the volume of the sample solution is 8BV, the sample is loaded at a flow rate of 2BV / h, and impurities are removed with 6BV of pure water and 3BV of 5% ethanol at a flow rate of 2BV / h , 4BV 60% ethanol was used to elute with a flow rate of 3BV / h to obtain an eluate, and the eluate was recovered under reduced pressure at ...
