| Abstract: | The adsorption of macroporous resin for flavonoids was studied in detail.The results showed that the LD601 macroporous resin has the best effection which compared with the D101,the LS-303B,the LX-28 and the LX-38 macroporous resins.In pH 2~4 HCl medium,the static adsorption capacity was 5 849.312 μg/g and at a flow rate of 2 mL/min,the adsorption rate of LD601 macroporous resin can reach 96.27%.The LD601 macroporous resin which 1 500 μg flavonoids adsorbed on can be eluted entirely by 50 mL 40% alcohol solution at a flow rate of 3 mL/min.The desorption rate can reach 97.51%. |
