大孔树脂对大果白刺花青素的分离纯化研究
Qinghai Science and Technology(2021)
Abstract
通过静态吸附特性研究,以吸附量和解析量为指标,从6种不同型号的树脂中筛选出对大果白刺花青素选择性好的树脂,然后考察各种工艺参数对树脂吸附及洗脱的影响.结果:DM21D大孔树脂对大果白刺花青素有较好的选择性,其最优工艺条件为大果白刺花青素上样液质量浓度0.128mg/mL,吸附流速为0.5mL/min,蒸馏水体积为4BV,洗脱剂浓度为70%,洗脱体积为4BV,洗脱流速为1mL/min.结论:DM21D型大孔树脂对大果白刺花青素具有良好的吸附与解析性能,适用于大果白刺花青素的纯化.
