摘 要:目的:采用离子交换树脂法脱色,精制大孔吸附树脂吸附分离得到的三七叶总皂苷。方法:静态吸附筛选适用的离子交换树脂,动态吸附流出曲线比较了2种阴离子交换树脂(D296,D t)的脱色性能;固定床柱操作方式阳离子交换树脂和阴离子交换树脂串联进行平行脱色实验。结果:Dt树脂的循环使用性能好,对三七叶总皂苷的脱色率近90%,获得品质好含量高的三七叶总皂苷产品。结论:离子交换树脂法脱色工艺,适用于精制三七叶总皂苷。The total leaves saponins of panax notoginseng decoloring by adsorption with exchange resins was studied and the decoloring capacity of six anions resins as adsorbent material was evaluated. The decoloring capacity of the selected resins ( D296 and Dt ) was compared by the dynamic adsorption decolorization experiments. Removel of coloured compounds in rew solution takes place in two serially coupled different ionic exchange columns, one packed column was I)72 cation resin, another anion resin. The results showed that macroporous anion exchange resin Dt was the best resin to decolorization of the total leaves saponins of panax notoginseng. The total saponin products with higher purity and quality were obtained. The results of this work shows that the method proposed is convenient, high efficcient and steady one.
