Embodiment

[0050] The anion exchange resin selected by the present invention is a novel resin containing strong and weak base functional groups, and its structural formula is:

[0051]

[0052] Full exchange capacity (mmol / g): 5.94

[0053] Weak base exchange capacity (mmol / g): 2.9

[0054] Moisture content: 50-60%

[0055] Granularity: 0.3-1.0

[0056] pH range: 0~14.

[0057] The specific implementation steps are:

[0058] 1 Preparation of upper column solution

[0059] Weigh 10.0 g of Panax notoginseng total saponins powder, add 20 ml of industrial ethanol and 80 ml of pure water and stir to dissolve it, and obtain the upper column liquid. Also can use the ethanol eluting concentrate after the macroporous resin adsorption from the notoginseng stem and leaf extraction process.

[0060] 2 fixed bed resin column decolorization

[0061] Pass the prepared D72 cation exchange resin column through 20ml of processed D72 cation exchange resin column, and the flow rate is controlled a...

Abstract

The invention relates to a decoloration refining process of total saponins of panax notoginseng leaf ions exchange resin and a resin regeneration method. The decoloration refining process is: first cation-exchange the dilute alcohol water solution of the total saponins of panax notoginseng leaf with resin column and then anion-exchange resin column to decolorate, and when the decoloration is completed, shower the resin column to reduce the loss of total saponins of panax notoginseng leaf and then depressing and steaming the solution and the shower solution, and the product is formed when the leftover is dried. The failure resin can regenerate to get the decoloration ability. The invention method can improve the purity of the produced total saponins of panax notoginseng leaf to more than 90 percent, and improve the exterior color and further be crystallized and purified to get products with high purity. The invention of ion-exchange resin decoloration refining process does not lead into other chemical matters in the process of total saponins of panax notoginseng leaf decoloration, thus avoiding polluting the product again in the process of decoloration. The decoloration process is easy, and the cost is low, while the decoloration effect is obvious and the equipment structure is simple.

Description

【Technical field】 [0001] The present invention relates to the further refining technology of the total saponins of Panax notoginseng produced by the macroporous resin adsorption method, especially the decolorization of the total saponins of Panax notoginseng using a new type of anion exchange resin containing strong and weak base groups as the decolorizing agent Refined process. 【Background technique】 [0002] Panax notoginseng (Burk.) F.H.Chen, scientific name Panax notoginseng (Burk.) F.H.Chen, is a plant of the genus Panax of Araliaceae. It is a treasure in the treasure house of Chinese medicine in my country. It is a famous and precious traditional authentic medicinal material. It is similar to ginseng. It contains a lot of medicinal chemical components. In terms of compounds, the largest components include saponins, polysaccharides, flavonoids, amino acids, absolute oils, and volatile oils; and there are nearly a hundred kinds of monomeric chemical substances with differ...
