Embodiment Construction

[0021] Below with the hydrochloric acid of 0.2mol / L concentration as example, limited embodiment is described as follows:

[0022] 1. Percolation

[0023] Take dried fritillary bulbs, coarsely crush them to obtain coarse powder, or slice them to obtain flakes, place them in a percolator, percolate with hydrochloric acid, and collect percolation liquid. The amount of hydrochloric acid is about 10 to 15 times the amount of medicinal materials.

[0024] When using different concentrations of hydrochloric acid or other protic acids, the settings and procedures used are the same.

[0025] 2. Separation

[0026] (1) Neutralize the percolation liquid with dilute alkali to pH 7.2-7.5, then extract it with ethanol for 4-5 times in the extractor, and combine the extracts to obtain the ethanol solution of the extract.

[0027] (2) The X-5 macroporous adsorption resin is used for pretreatment and then loaded into the column. The pretreatment is to wash with medical ethanol, and then to...
