| Abstract: | Through the comparison macroporous resin's adsorption and desorption capacity of flavonoids from asparagus,waste materials,the optimal condition of AB-8 resin for separating and purificating flavonoids was determined as follows:the adsorption velocity was 2 mL/min,elution velocity was 1.5 mL/min,the pH value of under-adsorpted solution was 6,the elution solvent was the volume fraction more than 70% ethanol solution,and the quantity of elution solvent was 200 mL.Finally,the flavonoids of purification product... |
