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