Purpose research departs from inside yew mellow extract the method of yew alcohol. The method uses high speed technology of refluent color atlas, use personal alkyl - ester of ester acerbity second - methanol - water (4:5: 3.5:5) is solvent system. Course high speed is refluent as a result color atlas rarefied, the quality mark of yew alcohol rises to 85.5 ﹪ by 5.1 ﹪ , reclaim rate achieve 98.6 ﹪ . Conclusion offerred a new approach for alcohol of yew of preparation tall purity.
Summarized nonlinear color atlas is academic (NLCT) departs in organic compound of young member of Chinese traditional medicine rarefied medium application. The material of active of yellow ketone of leaf of the bark of eucommia that has with this lab is nonlinear separate test considers to be exemple, brief introduction build Chinese traditional medicine young member material is nonlinear the scale that the theory of detached and rarefied system and methodological.NLCT use at material of young member of Chinese traditional medicine turns production, can exceed the appearance on the quantity, effect of chromatographic column of make the best use of, the purpose thing that achieves ideal is simple article. The application of this one theory and technology, can break through the traditional concept of linear enlarge, accelerate a lab to study achievement industrialization process, be helpful for Chinese traditional medicine the implementation of pharmacy modernization.
In recent years through reference molecular print technology departs rarefied Chinese traditional medicine is active the document of composition, be in to its yellow ketone, multivariate depart of body of phenolic, alkaloid, steriod, sweet legumin is rarefied medium application undertook summing up. Because molecular print technology is had alternative strong, operation wastage of simple, dissolvent is small wait for a characteristic, in Chinese traditional medicine good applied prospect was shown in modern research. In addition, the problem that still exists to its undertook be treatised simply.
