Embodiment 1
[0020] A preparation method for extracting total saponins from Platycodon grandiflorum which can be industrially produced, comprising the following specific process steps:
[0021] 1) Take the bellflower medicinal material, and grind the bellflower medicinal material into a powder of 10-100 mesh;
[0022] 2) adding water or 50-85% ethanol to the bellflower powder obtained in step 1), adjusting the solution to a pH value of 10-12 and then extracting to obtain an extract;
[0023] 3) Put the extract on a macroporous basic anion exchange column, wash it with alkaline water and pure water first, discard the washing solution, then elute with 50-85% ethanol, and concentrate the eluent to obtain the total saponins of Platycodon grandiflorum;
[0024] Wherein, the macroporous basic anion exchange column in step 2) is selected from macroporous weakly basic anion D392 exchange column, macroporous weakly basic anion D380 exchange column, macroporous weakly basic anion D382 exchange colum...
Embodiment 2
[0026] This embodiment is further optimized on the basis of the above embodiments. In order to further better realize the present invention, in the step 1), NaOH, KOH, Na 2 CO 3 or NaHCO 3 Adjust the pH of the solution.
Embodiment 3
[0028] This embodiment is further optimized on the basis of any of the above embodiments. In order to further better realize the present invention, the preparation process of the extract described in step 1) is as follows:
[0029] 1-1) adding bellflower powder to water or 50-85% ethanol to obtain a solution, the ratio of the powder to water or 50-85% ethanol is 1:3-5 by weight;
[0030] 1-2) Adjust the solution to an alkaline solution with a pH value of 10-12, heat or ultrasonically extract the alkaline solution for 2-4 times, combine the extracts, and filter; further remove impurities from the filtrate, and use alcohol precipitation for the water extract Impurities are removed, and the alcohol extract is removed by water precipitation to obtain a clear liquid after removal of impurities.
