| 摘 要： | 本文研究了多种大孔吸附树脂对白藜芦醇的吸附与脱附性能,从中选出H103树脂具有较大吸附量和解吸率.动态吸附实验研究了提取液浓度、pH、流速对H103树脂吸附量的影响,适合的上柱浓度为0.7157mg/ml,上柱液的pH为4.10,上柱液流速为2BV/h.4倍树脂床体积的80%乙醇以1BV/h的流速进行洗脱即可基本将白藜芦醇完全从H103树脂上解吸下来.

| Abstract: | The properties of static and dynamic adsorption and desorption of macroporous resin for Resveratrol were investigated. The H103 resin was selected to purify Resveratrol. The effects of concentration, pH and work speed of the infusion on the adsorption of the H103 resin were studied with static experiment. The concentration of 0.7157mg/ml, pH 4.10 and work speed of 2BV/h were the optimal conditions. Resveratrol absorbed on H103 resin was eluted with 4BV 80% ethanol in 1BV/h speed. |
