Abstract: The separation and purification of total flavonoids from Gnaphlium affine D. Don were carried out using AB-8 macroporous adsorption resin in this study. The effects of various factors on adsorption and desorption efficiency of the resin were investigated. The optimal adsorption conditions for sample loading velocity, pH value and concentration were 2 BV/h, 4.5 and 1.7 mg/mL, respectively, and the optimal desorption conditions were achieved by using 1.8 BV of 60% ethanol as desorption solvent at a flow rate of 1 BV/h. Under these conditions, the quantityof flavonoids the final product was 35.42%.
