    Abstract:

    In this manuscript,five types of macroporous resins were selected for adsorption and separation of flavonoids from Bamboo Shell.It was found that resin HPD600 was an excellent adsorbent with higher adsorption and desorption capacity.The effects of concentration,pH and flow rate of the solution on the dynamic adsorption of resin HPD600 were also studied.The results showed that the optimum adsorption conditions are listed as following: 7 BV flavonoids concentration of extract solution at 3.89 mg/mL,pH 3.0,flow rate at 3 BV/h using 6 BV40% ethanol as the best desorption solvent,the total recovery of chlorogenic acid reached at 82.33%,and the content of flavonoids reached at 35.12% in the crude product.
