Embodiment 1
[0051] The extraction method of flavonoids in the sealwort of embodiment 1
[0052] This embodiment discloses the extraction method of flavonoids in Polygonatum, the extraction preparation method is as follows:
[0053] a, by the weight-to-volume ratio of 1: 5m / v, carry out continuous countercurrent extraction at 60 ℃ with the pulverized raw material of Polygonatum leaf and stem and the water of 10% v / v and methanol mixed solvent, water and methanol mixed solvent are to every kilogram of Rhizoma Polygonatum The flow rate of the raw material is 2.5L / h;
[0054] b. After concentrating the extraction solution, the flavonoid crude product is dispersed with water and subjected to ultrafiltration. The ultrafiltration conditions are: the ultrafiltration membrane specification is 1K, the membrane penetration pressure is 20PSI, and the permeation flow rate is 15LMH to obtain the filtrate;
[0055] c. Adsorption and elution of the filtrate after ultrafiltration with polar resin, the ad...
