Abstract
A kind of preparation method of Syringin disclosed by the invention, specifically comprises the following steps：（1）Chinese medicine ilexrotunda is dry, crushing, sieving, are packed into extraction vessel；（2）It is extracted, combined extract, is concentrated into appropriate with solvent refluxing；（3）Alcohols solvent will be added in extracting solution, is heated to boiling, and decolourize；（4）By destainer impurity screening, and it is adjusted to neutrality, filtrate is concentrated；（5）Crystal refining processing.The preparation method of Syringin disclosed in this invention, the content of Syringin is high, extracts convenience, not only environmental protection but also has reduced costs.The method is easy quickly simultaneously, and separative efficiency is high, has reached good effect.
Description
Technical field
The present invention relates to a kind of extraction preparation methods of medium-height grass explosive component, the especially preparation method of Syringin.
Background technique
Syringin is usually extracted from the plants such as wilsonii, ilexrotunda, white lilac, saussurea involucrata and is got, have it is antitumor and
The effect of hemostasis.In the prior art, complex process, the loss of effective components for extracting Syringin are big, and extraction yield is lower, cost
It is higher, and largely waste resource.
Summary of the invention
To solve the above problems, the invention proposes a kind of environmental protection and the preparation methods of low-cost Syringin.
A kind of preparation method for Syringin that the present invention designs, specifically comprises the following steps：
（1）Chinese medicine ilexrotunda is dry, crushing, sieving, are packed into extraction vessel；
（2）It is extracted, combined extract, is concentrated into appropriate with solvent refluxing；
（3）Alcohols solvent will be added in extracting solution, is heated to boiling, and decolourize；
（4）By destainer impurity screening, and it is adjusted to neutrality, filtrate is concentrated；
（5）Crystal refining processing；
Preferably, alcohols solvent can be ethyl alcohol or methanol.
Preferably, step（3）It is middle to be decolourized using active carbon.
Compared with prior art, the content of the preparation method of Syringin disclosed in this invention, Syringin is high, extracts
It is convenient, not only environmental protection but also reduced costs.The method is easy quickly simultaneously, and separative efficiency is high, has reached good effect.
