大孔树脂吸附法吸附分离黄酮的研究

摘要

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 HC1 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%.%研究了D101、LD601、LS-303B、LX-28、LX-38型大孔树脂对黄酮的吸附及分离性能.结果表明,LD601型大孔树脂对黄酮的吸附效果较好,pH 2 ～4的盐酸溶液中,静态吸附量为5849.312μg/g,对流速2 mL/min黄酮溶液的吸附率可达96.27％,负载1500μg黄酮的LD601树脂,用40％乙醇50 mL以3 mL/min流速进行解吸,解吸率可达97.51％.
