Abstract

The invention discloses a preparation method of syringin. The method specifically includes the steps of: (1) drying, crushing, sieving the Chinese herbal material ilex rotunda, and loading the productinto an extraction container; (2) conducting refluxing extraction with a solvent, combining the extracted liquid, and conducting concentration to an appropriate amount; (3) adding an alcohol solventinto the extracted liquid, performing heating to boiling, and conducting decolorization; (4) filtering impurities out of the decolorized solution, adjusting the solution to neutral, and concentratingthe filtrate; and (5) carrying out crystallization refining treatment. The preparation method of syringin disclosed by the invention has the advantages of high syringin content, convenient extraction,environmental protection and cost reduction. At the same time, the method is simple and fast, has high separation efficiency and achieves a good effect.

Description

technical field [0001] The invention relates to a method for extracting and preparing components of Chinese herbal medicines, in particular to a method for preparing syringin. Background technique [0002] Syringin is usually extracted from plants such as eleuthero, iron holly, white clove, snow lotus, etc. It has anti-tumor and hemostatic effects. In the prior art, the process of extracting syringin is complicated, the loss of active ingredients is large, the extraction yield is low, the cost is high, and resources are largely wasted. Contents of the invention [0003] In order to solve the above problems, the present invention proposes an environmentally friendly and low-cost method for preparing syringin. [0004] A kind of preparation method of syringin designed by the present invention specifically comprises the following steps: [0005] (1) Dried, pulverized and sieved the Chinese herbal medicine Ilex, and put it into an extraction container; [0006] (2) Extract ...
