以杜仲叶60%乙醇提取液为原料,研究NKA-2、NKA-9、LS-600、HZ806、HZ906、HPD100、HPD500、S-8八种大孔吸附树脂对绿原酸的静态吸附与解吸效果,优化最优树脂分离纯化杜仲叶绿原酸的工艺技术参数。结果表明:NKA-2树脂对绿原酸具有较好的吸附与解吸性能,在pH3的条件下静态吸附量为86mg/g,解吸率达93.23%;当主要考虑绿原酸得率时,最优工艺参数为上样质量浓度4mg/mL、上样流速4BV/h、上样体积5BV、洗脱剂乙醇体积分数80%、洗脱流速为3BV/h、洗脱体积为2BV,在该工艺参数条件下,绿原酸得率为83.14%,纯度为28.91%;当主要考虑绿原酸纯度时,最优工艺参数为上样质量浓度4mg/mL、上样流速4BV/h、上样体积5B...

Different types of macroporous adsorption resin,including NKA-2,NKA-9,LS-600,HZ806,HZ906,HPD100,HPD500 and S-8 were compared for their static adsorption and desorption capacities for chlorogenic acid in 60% ethanol extract of Eucommiaulmoidues leaves.NKA-2 was found to have a stronger ability to adsorb and desorb chlorogenic acid and the optimal operating parameters for purifying chlorogenic acid from the ethanol extract using NKA-2 were determined.The static adsorption quantity of chlorogenic acid on NKA-2 and desorption percentage were 86 mg/...
