Title: Study on the Purification Process of Total Flavonoids of Sedum aizoon L.by Macroporous Adsorption Resin
Abstract: Taking Sedum aizoon L.as material,the dynamic adsorption and desorption performances of five kinds of macroporous adsorption resin including AB-8,HPD-100,D-101,DM-301,DM-130were researched to choose resin type; With the concentration of total flavonoids as indexes,adsorption and desorption conditions were investigated by single factor experiments.The technological conditions of the purification process of total flavonoids fromSedumaizoonL.by macroporous adsorption resin was investigated.The results showed that DM-301resin was selected to optimum purification technology,the conditions were:sample solution pH value was 3.0,the concentration was 1.63mg/mL,the adsorption rate was 2BV/h,2BV/h desorption rate using was 70%ethanol solution,desorption solution was 5BV.The total flavonoids of dry extract was purified from 8.99%to 25.6%,the enrichment ratio was about 3times.DM-301 macroporous resin used for enriching the total flavonoids of Sedum aizoon L.was better,the optimized operation was simple,the method was reliable.
