Purification of Total Flavonoids from Buddleja officinalis by AB-8 Macroporous Adsorption Resin

Abstract:

The separation and purification of total flavonoids from Buddleja officinalis were carried out by AB-8 macroporous adsorption resin. The optimum adsorption conditions for sample flow rate, pH value and feeding concentration were 2.0 mL/min, 4.5 and 1.6 mg/mL, respectively, and the optimum desorption conditions were obtained by using 2.0 BV of 70% ethanol as desorption solvent at a flow rate of 1.0 mL/min. Under these conditions, the flavonoids content of the final product was 90.43%, increased by 1.7 times than unpurified sample (53.09%).
