Abstract:
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 D72 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.
