[0024] A method for rapidly separating and purifying tangshenoside monomers from Codonopsis pilosula medicinal materials produced in Shanxi, the following steps are carried out at 55°C:
[0025] A. Cold extraction: crush the dried roots of Codonopsis pilosula through a 60-mesh sieve, mix and soak them with ethanol for 24 hours, cold soak and filter to remove slag, and the obtained liquid is recovered under reduced pressure to remove ethanol to obtain a concentrated extract; the mixing ratio is the volume of Codonopsis pilosula powder and The volume ratio of ethanol or methanol is 1:3. The ethanol concentration was 95%.
[0026] B. Coarse separation of resin: After diluting the concentrated extract in the previous step with water, filter it with a fine gauze cloth of about 200 meshes to remove solid impurities such as sand and dust before applying the macroporous resin, and then pass it into the activated macroporous adsorption resin column, elute the macroporous adsorption re...

[0033] A method for rapidly separating and purifying tangshenoside monomers from Codonopsis pilosula medicinal materials produced in Shanxi, the following steps are carried out at 25°C:
[0034] A. Cold soaking extraction: mix and soak the dried tuber root powder of Codonopsis pilosula and ethanol for 36 hours, remove the slag by cold soaking and filtration, and recover the obtained liquid under reduced pressure to remove ethanol to obtain a concentrated extract; the mixing ratio is that the volume ratio of Codonopsis pilosula powder and ethanol is 1: 3; The concentration of ethanol is 100%, and the particle size of the dried tuber root powder of Codonopsis pilosula is 40 mesh.
[0035] B. Coarse separation of resin: After diluting the concentrated extract in the previous step with water, filter it with a fine gauze cloth of about 200 meshes to remove solid impurities such as sand and dust before applying the macroporous resin, and then pass it into the activated macroporous ad...

[0040] A method for rapidly separating and purifying tangshenoside monomers from Codonopsis pilosula medicinal materials produced in Shanxi, the following steps are carried out at 58°C:
[0041] A. Cold soaking extraction: Mix and soak the dried root tuber powder of Codonopsis pilosula and ethanol for 30 hours, then filter and remove the slag by cold soaking, and recover the obtained liquid under reduced pressure to remove ethanol to obtain a concentrated extract; the mixing ratio is that the volume ratio of Codonopsis pilosula powder and ethanol is 1: 3; The concentration of ethanol is 100%, and the particle size of the dried tuber root powder of Codonopsis pilosula is 100 mesh.
[0042] B. Coarse separation of resin: After diluting the concentrated extract in the previous step with water, filter it with a fine gauze cloth of about 200 meshes to remove solid impurities such as sand and dust before applying the macroporous resin, and then pass it into the activated macroporous ...
